Using rigid polyurethane with low thermal conductivity and good heat insulation performance as the heat insulation material, it has excellent heat insulation.
When the water at 130 ℃ is transported beyond 40 kilometers after normal operation, the temperature drop is only about 1 ℃.
It has strong waterproof and anti-corrosion ability. It can be directly buried in the ground or water without the need for a pipe trench. The construction is simple and quick, and the overall cost is low.
It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in the frozen soil layer.
The prefabricated insulation pipe uses a corrosion-resistant (HDPE: high-density polyethylene) jacket tube, which is not affected by biological and chemical corrosion.
According to user needs, can provide pipes with various pipe diameters and insulation thicknesses between DN20 ~ DN1200 and matching fittings (elbows, tees, reducers, fixed joints, etc.)?
The products implement the CJ / T 114-2000 and CJ / T 115-2001 standards of the People`s Republic of China`s urban construction industry.
In order to ensure the trinity of the prefabricated direct buried insulation pipe, the outer surface of the steel pipe before foaming, and the inner surface of the plastic pipe are corona treated. The rust removal level reaches the requirements of Sa2.5 in GB / T 8923-1998. Dyne / cm.
The polyethylene outer protective tube is made of high-density polyethylene material, supplemented with various additives such as antioxidants, and strictly inspects the quality of raw materials and products to ensure that the product quality meets the CJ / 114-2000 standard and is directly buried. The technical requirements of the outer tube protect the overall quality of the outer tube. Specific technical indicators are shown in the table below.
The company is equipped with imported and domestic high-pressure foaming machines and hydraulic pipe-penetrating machines, which improves the overall quality of the products.
