Weihai polyurethane insulation pipe

Weihai polyurethane insulation pipe is anti-corrosion, with good insulation performance and long service life: the prefabricated polyurethane directly buried insulation pipe can play a good anti-corrosion role because the polyurethane rigid foam insulation layer is closely bonded to the steel pipe skin, which can isolate the infiltration of air and water. At the same time, its foam pores are all closed, and its water absorption is very low. The high-density polyethylene shell and fiberglass shell both have good anti-corrosion, insulation, and mechanical properties. Therefore, the outer skin of the working steel pipe is difficult to be eroded by external air and water.

The directly buried prefabricated insulation pipe, referred to as "pipe in pipe" or "jacket pipe", is a composite pipe that uses the excellent adhesion of polyurethane foam to skillfully combine the polyethylene shell or glass fiber reinforced plastic shell with rigid polyurethane foam plastic and steel pipe into an integral structure when foaming. Due to its better insulation performance, waterproofing, anti-corrosion, long service life, and easy construction compared to other structures, this pipe is currently the most advanced insulation material both domestically and internationally. Our company is responsible for on-site construction for users while ensuring product quality.

Steel sleeve steel buried insulation pipe/high-temperature steam insulation pipe/steel sleeve steel steam composite insulation pipe is suitable for transporting steam or other media below 2.5MPa and 350 degrees Celsius. This product uses steel pipes as the outer protective layer, which has the advantages of high strength, low damage, easy construction and maintenance, and long service life. The steel casing (steel sleeve steel) burial technology is a new burial technology that is waterproof, leak proof, anti-seepage, pressure resistant, and fully enclosed. It is a major breakthrough in the use of direct burial laying technology in areas with high groundwater levels. It is composed of steel pipes for conveying medium, anti-corrosion outer steel pipes, and ultra-fine glass wool filled between steel pipes and outer steel pipes. It can also be compounded by graphite, calcium silicate tile shell and polyurethane foam filled.

In short, prefabricated polyurethane buried insulation pipes not only have the technical and practical performance of traditional trench and overhead pipeline laying, but also have significant social and economic benefits, and are also powerful measures for heating energy conservation. The adoption of direct buried heating pipeline technology marks a new starting point for the development of heating pipeline technology in China. With the further improvement and development of this technology, it is imperative for heating pipelines to be buried directly instead of trenches and overhead structures
