Steel-lined polyethylene storage tank

Wuxi Xinlong Technology Co., Ltd. produces various models of chemical storage tanks in two major series:

1. Seamless Plastic PE Storage Tank Series: This series of products uses the company's proprietary PE formula as raw material and is manufactured through a rotomolding process for one-time integral molding. These plastic storage tanks and containers are produced without any additives or plastic fillers, entirely made from the company's PE (LLPE, HDPE) material. More importantly, from the tank body to the inlet/outlet ports, manholes, flanges, etc., everything is integrally molded in one go without any welding seams. As a result, the tanks feature no welding seams (the tank body, inlet/outlet ports, and flanges are all integrally molded without seams or welding, reducing chemical liquid leakage issues), no leakage, lightweight, aging resistance, impact resistance, corrosion resistance, cold and low-temperature resistance, and other characteristics, resulting in a longer service life under natural conditions.
Special Reminder for Purchasing Polyethylene Storage Tanks: We have repeatedly emphasized this many times, but some users still prefer to go for cheaper options. As the saying goes, "cheap is not good, and you get what you pay for." The key quality issue with polyethylene storage tanks is whether the tank body, inlet/outlet ports, level gauge ports, flanges, manholes, etc., are integrally molded in one go without welding. Due to the poor welding performance of polyethylene, the strength of welded joints cannot meet the required usage strength. Inlet/outlet ports that are added later (threaded method) or welded later (hot melt method) cannot meet the requirements of chemical non-leakage, dripping, or seepage. Therefore, when purchasing chemical polyethylene storage tanks, customers must ensure that the tank body, inlet/outlet ports, level gauge ports, flanges, manholes, etc., are integrally molded in one go without welding seams, fundamentally solving and reducing unnecessary running, leaking, dripping, and seepage issues. Never choose tanks with welded inlet/outlet ports.

2. Steel-Lined Plastic PE Storage Tank and Reactor Series: Steel-lined plastic (tortoise shell lining—steel, mesh, plastic integrated) is a series of steel-plastic composite products. It involves welding a steel mesh (tortoise shell) to the inner surface of the steel body, using PE as the raw material, and applying rotational lining technology (rotomolding) to integrally mold it onto the steel body surface in one go. Since the steel mesh (tortoise shell) and PE are integrated and the steel mesh is welded to the inner surface of the steel body, it is difficult for the PE to detach from the steel body's inner surface. This makes it an excellent corrosion-resistant product. The inner lining surface is smooth, sturdy, and even. Compared to traditional steel-lined plastic plate storage tanks and steel-lined fiberglass storage tanks, it offers better corrosion resistance, no leakage, no peeling, wear resistance, longer service life, and other advantages. It is an ideal storage and transportation container for corrosive liquids and can also be used for automotive transport tanks, pipelines, low-pressure tanks, vacuum tanks, reaction tanks, mixing tanks, ion exchange columns, pickling tanks, sedimentation tanks, neutralization tanks, electroplating tanks, extraction equipment, marine transport tanks, environmental protection equipment, etc., at temperatures below 90°C.

Wuxi Xinlong Technology Co., Ltd.'s rotomolding storage tank products include: seamless PE storage tanks (1-50 cubic meters); PE automotive urea tanks (20-50L); seamless PE automotive transport tanks (5-20 cubic meters); steel-lined plastic storage tanks (1-150 cubic meters); steel-lined plastic mixing tanks (1-50 cubic meters); steel-lined plastic pickling tanks, and other series of chemical anti-corrosion equipment. They are widely used in industries such as chemicals, biology, dyes, metallurgy, rare earths, smelting, machinery, power, electronics, electroplating, steel, automotive, environmental protection, textiles, brewing, food, aviation, water supply, drainage, and water treatment for chemical liquid storage. Products are sold to Jiangsu, Shanghai, Zhejiang, Fujian, Anhui, Jiangxi, Shandong, Shanxi, Hebei, Henan, Beijing, Tianjin, Liaoning, Jilin, Heilongjiang, Inner Mongolia, Ningxia, Shaanxi, Xinjiang, Qinghai, Hunan, Hubei, Chongqing, Sichuan, Guizhou, Yunnan, Guangdong, Guangxi, Hainan, and other provinces, municipalities, and autonomous regions.
