Residential heating steel sleeve steel steam steel pipe buried steel sleeve insulation pipe solid factory

Description :

　　Compared with various types of insulation pipes, directly buried prefabricated insulation pipes have outstanding advantages: -1. Good insulation performance, heat loss of only 25% of the pipe material, and long-term operation can save a lot of energy, significantly reducing energy costs. --2. It has strong waterproof and corrosion-resistant capabilities, does not require a pipe trench, can be directly buried underground or in water, is easy and fast to construct, and has a low overall cost.

　　The problem that is prone to occur during the welding production of buried insulation pipes is that, because the specifications of the straight seam are all submerged arc welding, if there is a broken wire or insufficient flux during normal welding, it is a troublesome matter. As long as there is a broken wire and the welding cannot keep up, such welds are unqualified and need to be repaired manually. Failure to repair them during construction can easily cause accidents. Generally, welding problems at both ends are more troublesome than repairing them, and welding problems in the middle are more troublesome.

　　Prefabricated buried insulation pipes have the advantages of insulation, waterproofing, anti-corrosion, thermal insulation, sound insulation, flame retardancy, cold resistance, anti-corrosion, corrosion resistance, lightweight and easy construction, etc. Compared with ordinary pipes, the actual insulation of prefabricated buried insulation pipes can achieve a heat loss of more than 40%. Prefabricated buried insulation pipes not only have more technical advantages than trench and overhead pipeline laying, but also have more practicality; The important thing is the prefabricated buried insulation pipe, which has good insulation performance and reliability. Another important point is the low cost of the project, which can effectively solve the problem of insulation and waterproofing in urban centralized heating where high temperature heat transfer is mostly between 130 ℃ and 600 ℃.

　　The on-site joint insulation of prefabricated buried insulation pipes processed by the manufacturer must be carried out after passing the pressure test, and the on-site joint insulation construction can only be carried out. The construction quality of prefabricated buried insulation pipelines directly affects their service life. There are two methods for insulation layer: on-site foaming construction and insulation tile construction. Regardless of which method is used for construction, defects such as circular space, cracking, and delamination cannot be present. There are various methods for layer construction (such as high-density polymer and fiberglass protective layer), but the integrity, tightness, and waterproofness of the joints must be ensured.
