Industry trends

The structure of high-temperature prefabricated directly buried thermal insulation pipe can be divided into three layers from the inside to the outside: the * layer is the working core pipe for conveying medium, which successfully solves the difficulty of waterproof and leakproof. The steel pipe is used as the external protective layer, and the high-strength high core pipe is generally made of seamless pipe (GB8163-87), spiral welded pipe (GB9711-88; SY/T5038-92), straight seam welded pipe (GB3092-93) and galvanized steel pipe; It can be selected according to different requirements of users. The core pipe diameter is [φ 22, 25, 32, 38, 45, 57, 76, 89, 108, 133, 15

Polyurethane foam plastic prefabricated insulation pipe price Polyurethane directly buried insulation pipe is closely combined with steel pipe for transmission medium, polyurethane rigid foam insulation layer and high-density polyethylene outer sleeve. This product is mainly used in urban central heating pipe network, oil transmission pipeline, water transmission pipeline in cold regions and industrial pipeline engineering in the plant area. It has * * * thermal insulation, waterproof and anti-corrosion and simple construction, It is not afraid of the advantages of plant root thorns. No trench laying is required for construction. It can be directly buried in the 0.6-1.2m frozen soil layer. The heat loss can be reduced by 40% compared with the traditional process, and the service life is more than 3-5 times longer than other heat insulation and anti-corrosion materials. The service life can reach

The price of polyurethane buried prefabricated insulation pipe can play a good anti-corrosion role because the polyurethane rigid foam insulation layer is tightly bonded to the outer skin of the steel pipe, which can isolate the infiltration of air and water. At the same time, its foam pores are closed, and its water absorption is very small. High density polyethylene shell and glass fiber reinforced plastic shell have good anti-corrosion, insulation and mechanical properties. The price of polyurethane buried prefabricated insulation pipe The directly buried prefabricated insulation pipe has outstanding advantages over traditional insulation pipes: 1. Good insulation performance, heat loss is only 25% of the traditional pipe, long-term operation can save a lot of energy and reduce energy costs. 2. It has a strong defense against
