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) materials. 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, with the tank body, inlet/outlet ports, and flanges all being integrally molded without welding, reducing chemical liquid leakage issues. They are also leak-proof, lightweight, anti-aging, impact-resistant, corrosion-resistant, and capable of withstanding extreme cold and low temperatures, offering 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, "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 for chemical leak-proof, drip-proof, and leakage-proof performance. 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 leakage, spillage, dripping, and leakage 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. A steel mesh (tortoise shell) is welded to the inner surface of the steel body, and PE is used as the raw material. Through the rotational lining process (rotomolding technology), the lining is integrally formed on 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 surface. This makes it an excellent corrosion-resistant product. The inner lining surface is smooth, even, and sturdy. Compared to traditional steel-lined plastic plate storage tanks and steel-lined fiberglass storage tanks, it offers better corrosion resistance, leak-proof performance, non-peeling, wear resistance, and a longer service life. 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 rotomolded storage tank products include: seamless PE storage tanks (1-50 m3); PE automotive urea tanks (20-50L); seamless PE automotive transport tanks (5-20 m3); steel-lined plastic storage tanks (1-150 m3); steel-lined plastic mixing tanks (1-50 m3); steel-lined plastic pickling tanks, and other series of chemical anti-corrosion equipment. They are widely used for chemical liquid storage in industries such as chemicals, biology, dyes, metallurgy, rare earth, smelting, machinery, power, electronics, electroplating, steel, automotive, environmental protection, textiles, brewing, food, aviation, water supply, drainage, and water treatment.
