Polyurethane pyrotechnic foams have good mechanical performance and insulation polyurethane pyrotechnic applications: polyurethane pyrotechnics are used in indoor and outdoor pipelines, centralized heating pipes, central air-conditioning pipes, chemicals, etc., temperature and cooling projects. Pur pyrotechnic tubes have evolved rapidly since the birth of polyurethane synthesis materials in the 1930s as a good insulation heat-preserving material, and their applications have become increasingly widespread, and have been extensively used in various pipelines, such as heating, refrigeration, oil, gas, gas, etc., because of their simple construction and energy-saving preservation effects. Large quantities are used for various pipelines such as heating, refrigeration, oil and gas。
Selection of tubes:
In general, according to design and client requirements, the following are: dn200 or less sutureless tubes (gb8163-87), dn200 or more swirl tubes (gb9711-88; sy/t5038-92) and straight welders (gb3092-93). Plumb surfaces can be up to sa2 grade in the gb8923-1988 standard and the surface can be rough up to r= 12. 5 microscale in the gb6060. 5-88 standard after treatment by advanced rust removal process rice
Performance characteristics:
1 thermal insulation of rigid polyurethanes with low argon coefficients and good insulation is used, with excellent insulation。
2. When the water at 130°c is transported 40 km away after normal operation, the temperature is only about 1°c。
3. Strong waterproofness and corrosive resistance, which need not be accompanied by a cleavage, can be buried directly into the ground or water, and construction is simple and quick, with low combined costs。
4. It also has good corrosive and shock resistant properties at low temperatures and can be buried directly in the tundra。
5. Prefabricated thermostats use corrosive (hdpe: hdpve) coatings, free from biological and chemical corrosion。
6 plumbers and corresponding tubes (curves, three-channels, transformers, fixed sections, etc.) for the dn20 ~ dn1200, depending on user needs
7. Product implementation* of the professional standards for town construction in the people's republic of china cj/t 114-2000 and cj/t 115-2001。
In order to ensure that the pre-prefabricated straight-to-preserve tubes are triaded, that the exterior steel pipe is treated and that the internal surface of the plastic tube is treated for tizziness, which is up to the level of rust as specified in sa2. 5 in gb/t 8923-1998, and that the outer-hull tube has a surface tension of 50 g/cm。
The use of high-density polyethylene (hdpve) materials in polyethylene exteriors, supported by a variety of aids such as antioxidants, as well as rigorous testing of raw materials and product quality to ensure that the product quality meets the cj/114-2000 standards and the technical requirements of the directly buried exteriors improve the overall quality of the exterior tube. Specific technical indicators are presented in the table below。
Companies are equipped with imported and domestically produced high-pressure blowing machines and hydraulic penetrators, which improve the overall quality of their products。
