Product Description: Price of Magnesium Alloy Sacrificial Anodes for Cathodic Protection of Long-Distance PipelinesJiaozuo Libo Light Alloy Co., Ltd.13939157916Magnesium is a commonly used sacrificial anode material in electrochemical cathodic protection engineering. It has high chemical activity, a relatively negative electrode potential, and a high driving voltage. At the same time, it is difficult to form an effective protective film on the surface of magnesium. Therefore, in aqueous media, the driving force of the micro-corrosion cells on the magnesium surface is large, the protective film is easily dissolved, and the self-corrosion of magnesium is intense. A hydrogen evolution reaction occurs at the cathode: 2H⁺ + 2e⁻ → H₂. Magnesium-based sacrificial anodes include three types: pure magnesium, Mg-Mn series alloys, and Mg-Al-Zn-Mn series alloys. Their common characteristics are low density, high theoretical capacitance, negative potential, low polarization rate, and a large driving voltage for steel (>0.6V). They are suitable for protecting metal components in high-resistivity soils and freshwater environments.Characteristics and Functions of Magnesium Anodes:Magnesium anodes, also known as magnesium alloy anodes or magnesium sacrificial anodes, are used in cathodic protection systems as important equipment and materials to prevent electrochemical corrosion. Their characteristics include low density, high theoretical capacitance, negative potential, low polarization rate, and a large driving voltage for steel (>0.6V). They are suitable for protecting metal components in high-resistivity soils and freshwater environments. Classification of Magnesium Anodes:Based on production processes, they are mainly divided into cast anodes and extruded anodes.Based on applications, they are mainly divided into water heater anodes and engineering anodes.Based on shapes, they are further classified into rod-shaped, strip-shaped, D-type, S-type, and custom-shaped anodes.Based on materials, they are mainly divided into AZ63, AZ31, AZ91, and other anodes.Applications of Magnesium Anodes:Typically, D-type and S-type anodes are mainly used in soil environments. Strip-shaped anodes are primarily used in high-resistivity soils, freshwater, and confined spaces, making them engineering anodes. Rod-shaped anodes are commonly used for anti-corrosion in electric water heaters and boilers.Magnesium anodes are specialized anti-corrosion materials for cathodic protection engineering. They possess extremely high electrochemical performance, consume uniformly, have a long service life, and generate a large amount of current. They are suitable for the cathodic protection of metal structures in soil and freshwater media. During the cathodic protection process, magnesium anodes consume evenly, resulting in a long service life. In practical applications, magnesium anodes provide more obvious protection for target structures. In soils with a resistivity greater than 8000 ohm·m, the use of magnesium anodes is recommended. more>

Product Description: Non-Detaching Screw NutApplied to panel screws: Non-detaching screws, also known as spring screws. Non-detaching screws can be riveted onto iron plates, allowing free screwing in and out. The entire assembly remains securely embedded in the panel without detaching, hence also called non-falling screws. The outer hand-twist sleeve is typically embossed with straight knurls for easy hand-tightening or manual fastening, so it is also referred to as hand-tight screws or hand-twist screws.Non-detaching panel screws (spring screws) can be used for installing PCB boards, occupying minimal space. The hand-tight screw's press-rivet sleeve features knurled teeth, pressed into the chassis or thin sheet holes (note: the drilled hole diameter of the thin sheet must meet specific requirements relative to the press-tooth diameter of the spring screw), forming an exposed spring screw that is hand-twisted at the other end (i.e., the hand-twist end). Due to the internal fixed spring, the screw moves in and out relative to the other end of the thin sheet. This solution addresses the challenge of frequently needing to remove screws and is very convenient and practical.Name: Non-detaching screw, panel screw, spring hand-tight screwMaterial: Combination of carbon steel screw, carbon steel press-rivet sleeve, and aluminum hand-twist sleeve; combination of stainless steel screw, stainless steel press-rivet sleeve, and aluminum hand-twist sleeve. The non-detaching panel screws produced by Yaoda Hardware*** are entirely manufactured and assembled in-house, except for the spring, which is outsourced, with strict quality control.The panel spring screw (non-detaching screw) consists of several components:1. Screw part (used to fasten the other end of the chassis thin sheet; typically made of carbon steel or stainless steel, with cross or slotted head for tool tightening)2. Hand-twist sleeve (usually knurled with straight patterns, typically made of aluminum, sometimes anodized black as needed)3. Press-rivet sleeve (used for riveting onto the panel)4. Spring (facilitates the extension and retraction of the screw and prevents the entire assembly from detaching)After each component is produced, they are assembled into one unit, and the hand-twist part is pressed to fit together with the press-rivet part via the spring, forming a complete non-detaching spring panel screw.PF21 Type PF22 Type Press-in Style Panel Fastener   Assemblies PF21 PF22PF21-M3-12.3PF21-M3-14PF21-M3-15.5PF21-M3-17.1PF21-M3.5-16.4PF21-M3.5-18PF21-M3.5-19.6PF21-M3.5-21.2PF21-M4-16.9PF21-M4-18.5PF21-M4-20PF21-M4-21.6PF21-M5-16.9PF21-M5-18.5PF21-M5-20PF21-M5-21.6PF21-M6-20.5PF21-M6-22.1PF21-M6-23.7PF21-M6-25.3PF21-440-12.3PF21-440-14PF21-440-15.5PF21-440-17.1PF21-632-16.4PF21-632-18PF21-632-19.6PF21-632-21.2PF21-832-16.9PF21-832-18.5PF21-832-20PF21-832-21.6PF21-032-16.9PF21-032-18.5PF21-032-20PF21-032-21.6PF22-M3.5-16.4PF22-M3.5-18PF22-M4-20PF22-M3.5-21.2PF22-M4-16.9PF22-M4-18.5PF22-M5-20PF22-M4-21.6PF22-M5-16.9PF22-M5-18.5PF22-M6-23.7PF22-M5-21.6PF22-M6-20.5PF22-M6-22.1PF22-440-15.5PF22-M6-25.3PF22-440-12.3PF22-440-14PF22-632-19.6PF22-440-17.1PF22-632-16.4PF22-632-18PF22-832-20PF22-632-21.2PF22-832-16.9PF22-832-18.5PF22-032-20PF22-832-21.6PF22-032-16.9PF22-032-18.5PF22-0420-23.7PF22-032-21.6PF22-0420-20.5PF22-0420-22.1PF22-0420-25.3 more>

Product Description:         Silicon molybdenum rods are available in two types: 1700 and 1800. The 1700 type uses the old process, while the 1800 type uses the new process. The main differences between them lie in the molybdenum content and the production process. The new process adopts a hot bending technique, allowing the rods to be bent freely to meet the special requirements of different customers. This enables selection based on production needs and appropriately reduces production costs. The price of the new process silicon molybdenum rods is higher than that of the old process for the same specifications.       Silicon molybdenum rod heating elements are suitable for use in air and neutral atmospheres. Reducing atmospheres such as hydrogen can damage the protective layer, while vapors of chlorine and sulfur can cause direct harm to the elements.The screws on the silicon molybdenum rod fixtures should not be tightened too much at once. The conductive wires should be in close contact with the white aluminum-sprayed parts of the cold ends of the rods to prevent sparking. When the elements reach high temperatures, tighten the screws again, as the elements become somewhat plastic and are less prone to breakage at this stage.At room temperature, silicon molybdenum rods have low bending strength and cannot withstand impact. Protective measures should be taken during installation to avoid breakage due to external pressure.       Regularly check whether the connections at various points of the silicon molybdenum rod heating elements are secure, and ensure that the electrical connections in the furnace temperature control system are in good condition.    more>

By measuring the differential pressure of an orifice plate, averaging pitot tube, or pitot tube, along with extraction negative pressure, methane concentration, and pipeline temperature, it calculates the mixed flow rate and pure methane flow rate of extracted gas. When using a pitot tube for measurement, either the center-point method or the Gaussian three-point method can be selected for measurement and calculation. It can measure flow data for up to 120 points.2) The instrument can be used as a single-parameter sensor, allowing separate measurement of differential pressure, negative pressure, methane concentration, or temperature at a specific point. Measurements are taken independently and stored separately for printing. It is not suitable for continuous monitoring in pump houses.All the above functions can be selected arbitrarily. The instrument allocates independent memory space for each function, ensuring they do not interfere with each other.  more>

Product Description: The long-term success of the continuous negative pressure automatic slag discharge and water drainer relies on quality. The longevity of a brand is not built on exaggerated marketing but on integrity. The effectiveness of a product does not depend on low prices but on quality, and your quality is ultimately determined by your vision.The PZ-L continuous negative pressure automatic slag discharge and water drainer adopts a dual-tank structure. By utilizing the height difference of the water inlet valve and the secondary adjustment of the water distribution system, it achieves continuous water storage and drainage functions. This effectively resolves the issue of water accumulation and blockage in gas extraction pipelines caused by intermittent drainage.Product SpecificationsApplicable Negative Pressure Range: -60 to -70 kPaDrainage Capacity: 10 to 15 m³/h (continuous drainage)Inlet Diameter: 50 mmOutlet Diameter: 50 mmOverall Dimensions: 800 × 500 × 580 mmWeight: 65 kgProduct Usage Precautions1. Avoid collisions during transportation; handle with care.2. After installation, ensure the drain valve is not submerged by water in the roadway, as this will prevent drainage.3. Keep the area around the drainer clean to avoid blockage of the drain valve by rock (coal) dust (mud).4. The central axis of the drainer should be as perpendicular to the horizontal plane as possible to reduce frictional resistance during the float's ascent.5. Regularly inspect the working condition of the drainer and address any issues promptly. more>
