Prefabricated direct buried polyurethane foam insulation pipe for heating insulation steel pipe

Description :

　　If you have any questions about prefabricated steam insulation pipes, polyurethane insulation pipes, insulation water pipes, steel jacket steam insulation pipes, and steam information, please contact the company further to obtain more information on the supply of directly buried prefabricated steam insulation pipes, polyurethane insulation pipes, insulation water pipes, steel jacket steam insulation pipes, and steam.

　　Directly buried prefabricated insulation pipes have outstanding advantages over traditional insulation pipes:

　　1. Good insulation performance, with heat loss only 25% of traditional pipes, long-term operation can save a lot of energy and significantly reduce energy costs.

　　2. It has strong waterproof and corrosion-resistant capabilities, does not require a pipe trench, can be directly buried underground or in water, is easy and fast to construct, and has a low overall cost.

　　3. It also has good corrosion resistance and impact resistance under low temperature conditions, and can be directly buried in frozen soil underground.

　　4. The service life can reach 30-50 years, and correct installation and use can greatly reduce the cost of pipeline maintenance.

　　5. A reporting system can be set up to automatically detect pipeline leakage faults, accurately indicate the fault location, and automatically report.

　　The classification of polyurethane insulation pipes is very complex. Generally, according to people's habits, there are several ways: 1. According to the temperature of the conveying medium, it can be divided into: normal temperature polyurethane direct buried insulation pipes, high temperature polyurethane direct buried insulation pipes, and deep cold polyurethane direct buried insulation pipes; 2. According to the different outer protective layers, it can be divided into: fiberglass outer protective layer polyurethane direct buried insulation pipe, high-density polyethylene outer protective layer polyurethane direct buried insulation pipe, steel outer protective layer polyurethane direct buried insulation pipe, and other outer protective layer direct buried insulation pipes; 3. There are many kinds of different transmission media: such as polyurethane prefabricated insulation pipe for water supply, high-temperature resistant polyurethane insulation pipe, directly buried polyurethane composite prefabricated insulation pipe for steam transmission, and buried rigid polyurethane foam plastic anti-corrosion insulation pipe for oil, etc. The insulation layer is made of rigid polyurethane foam with a density of 60kg/m3 to 80kg/m3, which can fully fill the gap between the steel pipe and the casing, and has a certain bonding strength, so that the steel pipe, the casing and the insulation layer form a solid whole. The polyurethane directly buried insulation pipe foam has good mechanical properties and thermal insulation properties. Generally, it can withstand 120 ℃. By modification or combination with other insulation materials, it can withstand 180 ℃. Overview: To adapt to urban centralized heating and construction Polyurethane directly buried insulation pipe polyurethane directly buried insulation pipe, also known as "pipe in pipe", is composed of high-density polyethylene outer protective layer, polyurethane rigid foam plastic pipe and steel pipe. Directly buried prefabricated direct buried insulation pipe (pipe in pipe) is composed of a steel pipe for conveying medium, a high-density polyethylene outer sleeve, a polyurethane rigid foam insulation layer filled between the steel pipe and the outer sleeve, which is tightly bonded. There are many other names such as polyurethane buried pipe, polyurethane prefabricated pipe, polyurethane direct buried prefabricated pipe, polyurethane jacket pipe, polyurethane foam insulation pipe, and so on.
