High density polyethylene direct buried insulation pipes are made of high-density polyethylene material, which has mechanical strength and excellent corrosion resistance, and can protect the pipes from damage caused by external factors during transportation, installation, and use.
High density polyethylene insulation pipe is an important factor affecting energy conservation, and polyurethane foam insulation steel pipe manufacturers are increasingly receiving widespread attention from countries around the world in their research and application. After the 1970s, foreign countries generally attached great importance to the production and application of insulated steel pipes, striving to significantly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. The insulation industry abroad has a long history, and new insulation materials are constantly emerging. Before 1980, the development of insulation pipes in China was very slow, and only a few insulation factories could produce a small number of underground buried insulation steel pipes. However, after more than 30 years of effort, especially after nearly 10 years of rapid development, many products in China's insulation industry have gone from scratch, from single to diversified, from low to high quality, and their applications have become increasingly common. Polyurethane material is currently a commonly used insulation material internationally. Rigid polyurethane has many excellent properties and is widely used in the field of thermal insulation in European and American countries.
The strength of polyethylene insulation layer made of high-temperature fiber felt and spiral welded pipe is generally higher than that of straight seam welded pipe. It can produce welded pipes with larger diameters using narrower billets, and can also produce welded pipes with different diameters using billets of the same width. The production process of seamless steel pipes is mainly achieved through the continuous rolling process of hollow base material without core rod, which is achieved through the process of expansion and reduction. The steel sleeve steel buried insulation pipe consists of an inner working steel pipe, an outer protective steel pipe, and an intermediate insulation layer. The working steel pipe is sandblasted and coated with two layers of anti rust paint. Prefabricated direct buried insulation pipe hot-rolled seamless steel pipe is resistant to high temperature and high pressure, suitable for medium temperature of 350 ℃, with strong pressure anti-corrosion ability, high anti-corrosion layer strength, and is not easily damaged. Seamless elbow is a type of pipe fitting used for pipeline bends. The proportion of all fittings used in the pipeline system is approximately. Usually, different forming processes are selected for elbows with different materials or wall thicknesses. The seamless elbow forming processes commonly used by manufacturers include hot pushing, stamping, extrusion, etc.

The overall performance of the polyethylene polyurethane insulation pipe is excellent, and the product strictly follows the CJ/T114-2000 industry standard. The working steel pipe adopts the process of shot blasting and rust removal on the outer surface and corona treatment on the inner surface of the outer protective pipe, further improving the three in one performance of the insulation pipe. The service life can reach 30-50 years, and correct installation and use can greatly reduce the cost of pipeline maintenance. The polyethylene outer protective pipe is made of high-density polyethylene material, which can ensure that the pipe is not damaged by external factors during transportation, installation, and use.
During production, the polyurethane combination must be weighed in strict accordance with the proportion required in the product specification, and the materials must be fully stirred evenly, otherwise the performance of polyurethane foam will be affected. When storing, it must be tightly sealed to prevent the escape of foaming agent and the entry of water vapor. It should be placed in a dark, dry, cool, and ventilated place, away from heat sources, and strictly protected from direct sunlight.
