High density polyethylene external protection foam insulation pipe

Polyurethane direct buried insulation pipes are widely used in liquid and gas transportation pipelines, chemical pipeline insulation engineering, petroleum, chemical, central air conditioning ventilation pipelines, municipal engineering, etc. Polyurethane direct buried insulation pipe is a type of prefabricated insulation pipe with good insulation performance, safety and reliability, and low engineering cost. Polyurethane buried insulation pipes not only have traditional trench and overhead pipeline technology and practical performance, but also have significant social and economic benefits, and are a powerful measure for heating energy conservation.

Application of polyurethane insulation pipe products: (used for heating insulation pipes, hot spring insulation pipes, heating insulation pipes, heating insulation pipes, air conditioning insulation pipes, steam insulation pipes, and cold insulation pipes). The product is composed of steel pipe for conveying medium (as working pipe), polyurethane rigid foam plastic (as insulation layer), high-density polyethylene outer sleeve or wrapped glass fiber reinforced plastic (as protective layer), which are closely combined.

Polyurethane direct buried insulation pipes only need to be buried in the soil, without the need for heating trenches. During construction, excavators are used to dig trenches according to the route, and polyurethane insulation pipes are placed and welded firmly. Insulation joints are also done well. Due to the high compressive strength of polyurethane insulation pipes and the high-density polymer outer shell, they have obvious advantages in corrosion resistance and resistance to harsh conditions. Polyurethane direct buried insulation pipe has good insulation effect, with a thermal conductivity of only 0.03, which is superior to other similar insulation products. Greatly accelerating the rate of heat dissipation, polyurethane insulation pipes can work with various temperature media. At almost high temperatures, composite insulation layers such as rock wool can be added to the pipes, greatly enhancing the high temperature resistance of polyurethane insulation pipes.

Polyurethane insulation pipe manufacturers are mainly engaged in the production and sales of pipeline foam insulation and various supporting insulation pipe fittings. They have strong technical strength, rich production experience, and attach great importance to the innovation and introduction of new technologies. They can strictly control the technical quality of their products. The direct buried insulation pipes they produce have good insulation performance, light mechanical height, and easy installation advantages. Regular models are in stock, and special requirements can be customized for processing!

Since the birth of polyurethane composite materials in the 1930s, hot water foam direct buried insulation pipes have been rapidly developed as an excellent insulation material, and their application scope is becoming more and more extensive. Moreover, due to the specifications of hot water foam direct buried insulation pipes, polyurethane insulation pipes, and polyurethane foam insulation steel pipes used in pipeline systems, elbows are pipe fittings that change the direction of pipelines. According to the angle, there are three commonly used types, and according to engineering needs, there are also other abnormal angle elbows. The materials for elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. The methods of connecting with pipes include: direct welding, commonly used flange connection, hot melt connection, electric melt connection, threaded connection, and socket connection. According to the production process, it can be divided into welded elbows, stamped elbows, cast elbows, etc. Other names: Degree Bend, Right Angle Bend, Love Bend, etc.
