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.

　　The steel sleeve embedding technology is a new type of embedding technology that integrates anti leakage, seepage, compression, and full sealing. This is a major breakthrough in the application of direct burial technology in areas with high groundwater levels. It consists of steel pipes for conveying media, anti-corrosion outer steel pipes, and ultra-fine glass wool or aluminum silicate wool filled between steel pipes and outer steel pipes. It can also be made of graphite, calcium silicate and polyurethane foam. The key issue for directly buried pipeline protective pipes is the firmness. In addition, it should also have good mechanical strength. Due to the high strength of the steel casing and the use of welded connections, the sealing performance is very high. In addition, its performance is unmatched by other external pipes.

　　Insulated pipelines are prone to breakage and leakage of substances due to thermal expansion and contraction, causing economic losses and polluting the surrounding environment. At this time, we need rock wool pipes to help. It is a new type of material for insulation, heat insulation, and sound absorption, made through special processes. By utilizing its excellent insulation and fire resistance principles, it effectively prolongs the service life of pipelines and prevents the occurrence of hazardous events. The better the rock wool pipe, the better its raw materials and the relatively high price.

　　The structure of steel sheathed buried steam insulation pipes is divided into two types based on the sliding mode: internal sliding type and external sliding type.

　　1. Internal sliding type: The insulation structure consists of a working steel pipe, aluminum silicate, drag reduction layer, microporous calcium silicate, insulation layer, stainless steel fastening steel strip, aluminum foil reflective layer, polyurethane insulation layer, outer steel pipe, and external anti-corrosion layer.

　　2. External sliding type: The insulation structure consists of a working steel pipe, a glass wool insulation layer, an aluminum foil reflective layer, a stainless steel fastening strap, a sliding guide bracket, an air insulation layer, an external protective steel pipe, and an external anti-corrosion layer.

　　The thermal compensation of the steel sleeve buried steam insulation pipe adopts a corrugated pipe compensator, which is installed inside the casing and made in a direct burial form without the need for an observation well. The construction operation is convenient and the construction period is short.

　　Technical parameters of steel sleeve buried steam insulation pipe:
