Polyurethane insulated steel pipe manufacturer has low thermal conductivity and good thermal insulation performance

Tianyuan Anti-corrosion Steel Pipe Co., Ltd. Manager Zhang Black Jacket Polyurethane foam insulation pipe foam has good mechanical properties and thermal insulation Polyurethane insulation pipe applications: Polyurethane insulation pipes are used in various indoor and outdoor pipes, central heating pipes, central air conditioning pipes, chemical industry, and other industries Pipeline insulation and cold insulation projects. Overview: Since the birth of polyurethane synthetic materials in the 1930s, polyurethane foam insulation pipes have been developing rapidly as an excellent thermal insulation material. They have significant energy-saving and anti-corrosion effects and are widely used in various heating, oil and steam transportation. and other various pipelines. It is widely used in various pipelines such as heating, refrigeration, oil transportation, and steam transportation.
Performance characteristics
Use rigid polyurethane with low thermal conductivity and good thermal insulation performance as the thermal insulation material, which has excellent thermal insulation.
After normal operation, when water with a temperature of ℃ is transported to kilometers away, the temperature drop is only about ℃.
, has strong waterproof and corrosion resistance, no need for attached pipe trenches, and can be directly buried in the ground or water. The construction is simple and fast, 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 outer casing, which is not affected by biological and chemical corrosion.
, Pipes of various diameters and insulation thicknesses and matching pipe fittings (elbows, tees, reducers, fixed joints, etc.) can be provided according to user needs
In order to ensure that prefabricated straight The trinity of buried insulated pipes, the outer surface of the steel pipe is treated before foaming, the inner surface of the plastic pipe is corona treated, the rust removal level reaches the specified requirements, and the inner surface tension of the outer shell pipe reaches dyne/cm.
The polyethylene outer protective pipe is made of high-density polyethylene material, supplemented by various additives such as antioxidants. The raw materials and product quality are strictly inspected to ensure that the product quality meets the standards and is directly buried outside the pipe. The technical requirements for protecting pipes have improved the overall quality of externally protected pipes. See the table below for specific technical indicators.
