Manufacturer directly buried hot water prefabrication Thermal insulation pipe Key points of construction
polyurethane The insulation pipe has excellent performance and is suitable for construction and service life industries. It is made of high functional polyether polyol and benzene Polyisocyanate as the main raw material.
Key construction points of manufacturer's directly buried hot water prefabricated insulation pipe
Production process 1, feeding 2, extrusion 3, mold 4, cooling 5, traction 6, corona treatment of inner surface 7, cutting 8, inspection 9, finished product
The polyurethane insulation pipe has the following characteristics in structure:
1. Working with fixed inside Steel pipe Flow on Bracket Friction with the inner wall of the outer casing, the thermal insulation material moves with the working steel pipe, and there will be no mechanical wear and pulverization of the thermal insulation material.
2. The outer steel pipe has high strength, good sealing performance, and can effectively waterproof and impermeable.
3. The outer wall of the outer sleeve steel pipe is treated with high-quality anti-corrosion treatment, so that the service life of the anti-corrosion coating of the outer sleeve steel pipe is more than 20 years.
4. The thermal insulation layer of the working steel pipe is made of high-quality thermal insulation materials with good thermal insulation effect.
5. There is a gap of about 10~20 mm between the working steel pipe insulation layer and the outer steel pipe, which can be used for further insulation. It is also a relatively unobstructed drainage channel for the directly buried pipeline, so that the tide drainage pipe can truly play the role of timely tide drainage, and play the role of signal pipe at the same time; Or it can be pumped into a low vacuum, which can more effectively insulate the heat and reduce the corrosion of the inner wall of the outer sleeve.
The polyurethane directly buried thermal insulation pipeline has been developed rapidly as a good thermal insulation material since the polyurethane synthetic material was born in the 1930s, and its application scope is also increasing, especially because of its simple construction and remarkable energy-saving and anti-corrosion effects. It occupies all walks of life.

6. Safety HDPE outer protective pipe polyurethane foam prefabricated directly buried thermal insulation pipe is popular for its excellent performance, convenient construction and long service life (30-50 years). Its structure is composed of three parts: outer protective layer, thermal insulation layer and anti leakage layer. The outer protective layer is made of polyethylene jacket pipe or glass fiber reinforced plastic or other materials. The laying methods include direct burial, overhead laying and trench laying.
The company first introduced foreign new technology and equipment, and has 16 extruder production lines, which can produce Ф 70 (mm) - 1680 (mm) super large polyethylene jacket pipes at a high speed. The product quality has reached or exceeded national standards and has been approved for testing. More than 200 specifications and models are available, and the delivery is timely and the quality is excellent. In addition, the prefabricated polyurethane directly buried insulation pipes, winding FRP polyurethane directly buried pipes, prefabricated high-temperature composite polyurethane directly buried pipes, steel sheathed steel directly buried pipes and other products produced by the company have been recognized by the national quality inspection department, and can independently undertake the design and construction of large-scale insulation projects. For a long time, our products have been widely used in industrial and mining enterprises, petrochemical enterprises, urban central heating pipe networks, residential areas and other fields throughout the country, and have been highly praised by users.
