Basic structure of the steam generator body: steam drum
Negotiable
Category: Chemicals/Dyes/Basic Dyes
Company: Shaanxi Deli Energy Technology Co., Ltd.
Product Description: Drum: It is a cylindrical vessel in natural circulation and multiple forced circulation boilers that receives feedwater from the economizer, connects the circulation circuit, and delivers saturated steam to the superheater. The drum body is made of high-quality thick steel plates and is one of the heaviest components in the boiler.The main functions of the drum are to store water, perform steam-water separation, and discharge brine and sludge from the boiler water during operation to prevent boiler water with high concentrations of salts and impurities from entering the superheater and steam turbine along with the steam. If these salts and impurities cause scaling, salt deposition, and corrosion in the superheater tubes and steam turbine passages, they can affect the economic and safe operation of the equipment. The steam at the boiler outlet generally meets certain quality standards. The internal devices of the drum include steam-water separation and steam washing devices, feedwater distribution pipes, blowdown and chemical dosing equipment, etc. The steam-water separation device separates saturated steam from the water coming from the water-cooled walls and minimizes the fine water droplets carried in the steam. Medium and low-pressure boilers commonly use baffles and gap baffles as coarse separation elements. In boilers above medium pressure, various types of cyclone separators are widely used for coarse separation, followed by further separation using louvers, wire mesh, or steam distribution plates. With advancements in water treatment technology, steam separation devices tend to be simplified and standardized. Blowdown devices (including continuous and periodic blowdown) can discharge a portion of boiler water containing higher salts and sludge during boiler operation. The drum is also equipped with monitoring and protection facilities such as water level gauges and safety valves. more>

Basic structure of the steam generator body: furnace chamber
Negotiable
Category: Chemicals/Dyes/Basic Dyes
Company: Shaanxi Deli Energy Technology Co., Ltd.
Product Description: The furnace, steam drum, burner, water-cooled wall, superheater, economizer, air preheater, framework, and furnace wall in the boiler body of a steam generator constitute the core components for steam production, collectively referred to as the boiler proper. The two most critical components in the boiler proper are the furnace and the steam drum.Furnace: Also known as the combustion chamber, it is the space where fuel is burned. A furnace that burns solid fuel on a grate in a bed of fire is called a stoker-fired furnace, also known as a bed furnace; a furnace that injects liquid, gaseous, or pulverized solid fuel into a fire chamber for combustion is called a chamber-fired furnace, also known as a fire chamber furnace; a furnace where air suspends coal particles for fluidized bed combustion, suitable for burning low-grade fuels, is called a fluidized bed furnace; a cylindrical furnace that uses an air stream to make coal particles rotate at high speed and burn intensely is called a cyclone furnace.The cross-section of a furnace is generally square or rectangular. Since fuel burns in the furnace to form flames and high-temperature flue gas, the furnace walls surrounding it are constructed from high-temperature-resistant and insulating materials. Water-cooled wall tubes are often installed on the inner surface of the furnace walls, which not only protect the walls from being damaged by fire but also absorb a significant amount of radiant heat from the flames and high-temperature flue gas. The structure, shape, volume, and height of the furnace must ensure complete fuel combustion and reduce the flue gas temperature at the furnace outlet below the temperature at which slag begins to condense.When the temperature inside the furnace exceeds the ash melting point, the ash becomes molten. Molten slag particles adhere to the water-cooled wall tubes or other components when they come into contact with them. As the adhered ash particles accumulate, they form slag blocks, a process known as slagging. Slagging reduces the heat transfer efficiency of the boiler's heating surfaces. In severe cases, it can block the flue gas flow passages, affecting the safe and economical operation of the boiler.Furnace design must fully consider the characteristics of the fuel used. Each boiler should ideally burn the fuel it was designed for. When fuels with significantly different characteristics are used, the economic efficiency and reliability of boiler operation may be compromised. more>

Vanderlee Boiler (Diagram)_Number of Modular Boilers_Gansu Modular Boiler
Negotiable
Category: Machinery & Equipment/Electric Heating Equipment/Medium Frequency Power Supplies
Company: Shaanxi Deli Energy Technology Co., Ltd.
Product Description: Features of Vandelay Gas Modular Boilers 1. Modular design, simple structure, flexible and convenient installation The concept of a modular gas boiler is equivalent to splitting a single large boiler into several smaller units. Therefore, modular boilers can achieve the scale of any steam tonnage through "simple parallel combination" in quantity, making them capable of replacing various heating and hot water boilers below 10 steam tons commonly used today. In large boilers, the air-gas mixture is delivered into the furnace by a blower, which generates significant noise, causing sound pollution and worsening the working environment for employees. In contrast, modular boilers utilize atmospheric combustion, eliminating the need for a blower. As a result, they operate very quietly—only a slight "whooshing" sound is heard during combustion, with no other noise. Most modular boilers use burners made of special aluminized steel materials, specifically designed with aerodynamic processes to ensure highly efficient gas combustion. Tests have proven a combustion efficiency of over 98%. Complete combustion reduces the nitrogen oxide content in the flue gas, minimizing environmental pollution. Vandelay gas modular boilers feature staged startup, resulting in significant energy savings. The modular boiler system automatically adjusts the startup and shutdown of modules based on the system’s thermal load through its staged startup function. When one module reaches full load, another module is activated, ensuring that the system’s heat output always matches the actual demand. This guarantees that each boiler operates at high efficiency, maximizing the overall system’s operational thermal efficiency and completely eliminating the energy waste common in traditional large boilers. Additionally, the control system automatically balances the operating time of each module, extending the overall system lifespan. In summary, the Vandelay gas modular boiler series represents a breakthrough in design concept and form compared to traditional boilers. This series offers unparalleled advantages in environmental protection, energy efficiency, safety, automation, lifespan, installation, power consumption, capacity expansion, footprint, and space utilization. It has been widely applied in various new and renovated heating and hot water projects. Vandelay gas modular boilers are safe and reliable. In open installation systems, the water pressure system operates under constant atmospheric pressure and includes multiple comprehensive safety protections: flameout protection, dry burn protection, freeze protection, low water level protection, automatic exhaust protection, overheat protection, and leakage protection. In closed installation systems, the sealed water circuit operates under a pressure of 0.05–0.3 MPa. In addition to the safety features of open systems, closed systems also include: pressure expansion protection, low water pressure protection, and a safety pressure relief device for high-pressure conditions. more>

Q390E steel, introduction to the reasons for unqualified low-temperature impact of Q390E steel plate
$5000
Category: Others
Company:
Product Description: The reasons for the failure of low-temperature impact in Q390E steel may include the following aspects:Unreasonable chemical composition. For example, excessively high carbon content or excessively low manganese content may lead to failure in low-temperature impact.Inappropriate heat treatment process. During heat treatment, temperature and cooling rate directly affect the low-temperature toughness of the steel plate. Excessively high or low temperatures, as well as excessively fast or slow cooling rates, may result in reduced low-temperature impact performance.Unreasonable coil forming process. During the forming process, the steel plate undergoes significant stretching and compression, which may cause cracks and fractures at low temperatures, thereby reducing low-temperature impact performance.Unreasonable content of alloying elements. The content of elements such as chromium and nickel is related to low-temperature strength. Chromium can improve the corrosion resistance of steel but has little effect on low-temperature toughness, while nickel can improve the toughness of steel but has little effect on corrosion resistance. Therefore, appropriate additions of elements such as nickel and chromium can simultaneously enhance the toughness and corrosion resistance of the steel plate, thereby improving its low-temperature impact performance.To address this issue, the following measures can be taken:Optimize the material formulation and reasonably control the chemical composition, such as carbon and manganese content.Optimize the heat treatment process by establishing appropriate heating and cooling systems to achieve good low-temperature toughness.Optimize the coil forming process to reduce potential issues such as cracks and fractures during forming.Reasonable combination of alloying elements, with appropriate additions of elements such as nickel and chromium to improve the toughness and corrosion resistance of the steel plate.In summary, the reasons for the failure of low-temperature impact in Q390E steel are multifaceted and require comprehensive consideration of material formulation, heat treatment process, coil forming process, and alloying element content. By implementing corresponding measures, the low-temperature impact performance of the steel plate can be effectively improved. more>

Three-dimensional flexible welding platform overcomes challenges of aluminum alloy welding deformation and precise positioning.
$2311
Category: Metallurgy & Minerals/Non-Ferrous Processed Materials/Non-Ferrous Metal Sheets
Company:
Product Description: The 3D flexible welding platform is specifically designed for the welding industryThe welding industry is facing dual challenges: the transition to "multi-variety, small-batch" production and the quality requirements of "high precision and efficiency." Traditional welding fixtures suffer from poor adaptability, slow changeover, and significant precision fluctuations, making it difficult to meet the complex welding demands of automotive parts, engineering machinery structural components, and more. As a core equipment customized for the welding industry, the 3D flexible welding platform is fully tailored to welding production scenarios in terms of material, structure, function, and interfaces. With specialized designs such as modular reconfiguration, high-precision positioning, and strong load-bearing and vibration resistance, it has become a "flexible tool" to address industry pain points. This article details its industry-customized design highlights and application value.1. Material and Structure: Exclusive Adaptability Design for Welding ScenariosThe high-temperature, high-vibration, and heavy-load environments of the welding industry require the platform to possess strong durability and stability. The platform has been optimized in material and structure accordingly:High-Temperature and Deformation-Resistant Material: HT300 gray cast iron or QT600 ductile iron (welding industry materials) is selected, undergoing 550°C high-temperature aging + 6 months of natural aging treatment, with a residual stress removal rate ≥85%.Vibration and Impact-Resistant Structure: The bottom adopts a "cross-rib plate + box-type main body" design, with rib plate thickness of 12-15mm and spacing of 200-250mm, forming a dense support network. A 2000×3000mm platform has a rated load capacity of up to 30 tons, absorbing over 80% of high-frequency vibrations (50-200Hz) during welding, with a vibration transmission rate ≤15%, avoiding weld seam deviation caused by vibrations. For heavy-duty workpiece welding (e.g., engineering machinery booms over 10 tons), the table thickness is increased to 200mm to further enhance impact resistance and prevent table surface dents caused by welding impacts;2. Core Functions: Customized Solutions for Welding ProductionAddressing the core needs of the welding industry for "fast changeover and multi-process coordination," the platform features three exclusive functions:Modular Quick Reconfiguration: A standardized modular system customized for multi-variety welding, including dozens of specialized modules such as square boxes, angle rulers, support blocks, and quick-locking pins. All modules are combined via T-slots on the table surface (slot width 16/22/28mm, spacing 50/100mm, common specifications in the welding industry). When switching between different welding workpieces, there is no need to redesign fixtures; only module layout adjustments are required, reducing changeover time from 4-8 hours with traditional fixtures to 15-30 minutes. For example, automotive plants switching between "car chassis" and "SUV chassis" welding, or engineering machinery plants switching between "excavator arms" and "crane booms" welding, can quickly adapt, significantly enhancing production line flexibility;3. Scenario-Based Customization: Covering Full Industry Welding NeedsThe platform provides customized solutions for different细分 scenarios in the welding industry, adapting to all types of welding from small parts to heavy structural components:Automotive Industry Welding: Customized for components such as new energy vehicle battery trays and body frames, using 2000×3000mm Grade 0 precision platforms equipped with small positioning modules and quick-locking mechanisms. Positioning error ≤±0.06mm, meeting weld seam sealing and dimensional precision requirements (tolerance ±0.2mm), with changeover efficiency improved by 300%, adapting to multi-model customized production;Every design aspect of the 3D flexible welding platform closely aligns with the production characteristics and needs of the welding industry—materials suited for high temperatures and heavy loads, structures resistant to vibrations and impacts, functions enabling fast changeover and precise positioning, and interfaces compatible with automated equipment. As a core equipment customized for the welding industry, it not only addresses many pain points of traditional fixtures but also drives the transformation of welding production from "rigid" to "flexible," helping enterprises improve efficiency, stabilize quality, and reduce costs in multi-variety competition. As the demand for flexible production in the welding industry becomes increasingly urgent, this exclusively customized 3D flexible welding platform will become a key support for industry transformation and upgrading, propelling welding production toward a new stage of higher efficiency, greater precision, and enhanced flexibility.Weiyue Machinery Ms. Xie 15350773479 more>

Category: Others
Company: Hengshui Changjiang Prestressing Co., Ltd.
Product Description: GPZ(KZ) 2DX±50 Seismic Pot Bearing for Bridges ManufacturerThe GPZ(KZ) series seismic pot rubber bearings include two types: fixed bearings and unidirectional movable bearings, along with bidirectional movable bearings for配套 use. The bearing specifications are divided into 31 grades according to JT391-1999 requirements. The vertical design bearing capacity, bearing rotation angle, bearing friction coefficient, and displacement are all designed in accordance with standard requirements. Only the horizontal force in all directions of the fixed bearings and the non-sliding direction of the unidirectional movable bearings has been increased from 10% to 20% of the original bearing design capacity.Currently, both rigid seismic resistance and flexible shock absorption methods are adopted domestically and internationally. GPZ(KZ) 2DX±50 Seismic Pot Bearing for Bridges Manufacturer, Rigid seismic resistance requires increasing the size of the structure (including the foundation structure and seismic bearing structure). The characteristics of flexible shock absorption are: good shock absorption performance but relatively small stiffness, with the possibility of damage under strong seismic waves. This series of bearings adopts effective seismic measures such as a combination of rigidity and flexibility, increasing the energy dissipation capacity of the bearings and greatly improving their seismic performance.GPZ(KZ) 2DX±50 Seismic Pot Bearing for Bridges Manufacturer, Therefore, during an earthquake, it can enhance the bridge's seismic resistance,最大限度地 limit the relative displacement between the upper and lower structures of the bridge, and reduce the amplification factor of seismic forces. When there is no earthquake, it functions等同 to general pot rubber bearings.Since the GPZ(KZ) series seismic pot rubber bearings are designed with fixed bearings and unidirectional movable bearings, the combined use of these two types of bearings compared to installing seismic bearings only on the fixed piers of the bridge undoubtedly improves the seismic resistance of the entire bridge structure.Structural form of GPZ(KZ) pot rubber bearings: GPZ(KZ)GD (Fixed Seismic Pot Rubber Bearing), mainly GPZ(KZ) 2DX±50 Seismic Pot Bearing for Bridges Manufacturercomposed of an upper seat plate, energy dissipation plate, sealing ring, rubber plate, pot base, and damping rubber ring, etc. GPZ(KZ)DX (Unidirectional Movable Seismic Pot Rubber Bearing) also includes an intermediate steel plate, PTFE sliding plate, stainless steel sliding plate, and lateral sliding device, etc. The shock absorption principle is mainly that when the horizontal force on the bearing exceeds 20% of the design vertical bearing capacity, the energy dissipation plate begins to slide, providing the first isolation effect; then the damping ring发挥 the second damping effect, and the bearing serves its seismic role; when the seismic shock wave exceeds a certain limit, the rigid seismic resistance of this series provides the third seismic effect. more>
