Driven by technology and striving for survival through quality. Seek efficiency from quality. Benefit comes from the return of serving society. Enterprise tenet: Quality comes before production, customer first, providing customers with excellent products and thoughtful services. Our commitment: The market is changing, but our commitment remains unchanged. The company adheres to the principle of "excellent quality, reputation first" to serve society and benefit humanity. Our company mainly produces polyurethane composites, foam insulation boards, foam insulation pipes, rock wool products, FRP winding pipes, and high-density polyethylene black and yellow jacket pipes (i.e., thermal insulation outer protective layer); Prefabricated polyurethane direct buried insulation pipe (i.e. pipe foam insulation); Prefabricated insulation elbow; Prefabricated insulation pipe fittings; Waiting for insulation materials. Our company can customize various shaped products according to customer requirements. And undertake polyurethane foam insulation projects for various large, medium, and small pipelines such as steam pipes, plumbing pipes, air conditioning pipes, power pipes, HVAC pipes, etc.

　　Prefabricated polyurethane insulated steel pipes are divided into three layers from inside to outside: layer: working steel pipe layer. Seamless steel pipes, spiral steel pipes, and straight seam steel pipes are generally selected according to the design and customer requirements. After advanced shot blasting and rust removal process, the rust removal grade of the steel pipe can reach Sa2 level in GB/T8923-1988 standard, and the surface roughness can reach R=12.5 microns in GB6060.5-88 standard. The second layer: polyurethane insulation layer: it is made by injecting the original liquid of rigid polyurethane foam into the cavity formed between the steel pipe and the outer protective layer with a high-pressure foaming machine at one time, which is commonly known as "pipe in pipe foaming". Third layer: high-density polyethylene protective layer: prefabricated black or yellow polyethylene plastic pipes with a certain wall thickness. Polyethylene is odorless, non-toxic, and feels like wax. It has excellent low-temperature resistance and can be used at temperatures ranging from -70 to -100 ℃. It has good chemical stability and can withstand most acid and alkali attacks (not acids with oxidizing properties). It is insoluble in general solvents at room temperature and has low water absorption. However, as a linear molecule, it can slowly dissolve in certain organic solvents without swelling, and has excellent electrical insulation properties. Its functions are twofold: firstly, to protect the polyurethane insulation layer from mechanical damage caused by hard objects; secondly, to prevent corrosion and waterproofing. High density polyethylene polyurethane foam insulation steel pipes shall comply with the SY/T114-2000 and SY/T115-2001 standards.
