Polyurethane insulation pipe is widely used in gas transmission pipe network, chemical pipeline insulation engineering, petrochemical industry, central air conditioning ventilation pipe, municipal engineering, etc. Polyurethane direct buried heat preservation pipe is a kind of direct buried prefabricated heat preservation pipe with good heat preservation performance, safety and reliability, and low engineering cost. Polyurethane insulation pipe has many other names, such as polyurethane pipe, polyurethane precast pipe, polyurethane precast directly buried pipe, polyurethane jacket tube, polyurethane foam insulation pipe, so it is not introduced here. Today, polyurethane insulation pipe manufacturers mainly introduce polyurethane insulation directly buried tube specification parameters and insulation tube how many meters?

　　Polyurethane direct buried insulation pipe

　　If you want to know the specifications and parameters of polyurethane insulation pipe, you should first know the composition and structure of insulation pipe products.

　　(1) Working steel pipe: according to the technical requirements of transmission medium, welded steel pipe with seam, seamless steel pipe and double-sided submerged arc spiral steel pipe are used respectively.

　　(2) insulation layer: rigid polyurethane foam felt or aerogel felt.

　　(3) Protective shell: high density polyethylene or glass fiber.

　　(4) Leakage alarm: high temperature prefabricated directly buried insulation pipe shall be manufactured close to the steel pipe insulation, and a warning shall be embedded. Once the pipe leaks, the conduction shall pass through the warning line, and the test instrument can alarm and display the accurate leakage position and degree. In order to inform the maintenance personnel to deal with the leaking pipe quickly and ensure the safe operation.

　　In formal work, due to the seamless steel pipe and welded steel pipe of polyurethane heat preservation pipe, the length of heat preservation pipe is the range of base metal length. The length of insulation pipe, main length and working steel pipe, steel pipe, if it is working spiral steel pipe, it is generally 12 meters long, if it is seamless steel pipe, it is uncertain foot, usually 4-12 meters, Usually, a prefabricated polyurethane direct buried insulation pipe with the norm of 12 meters can also be customized and processed according to the customer's requirements.

　　The above is the specification parameters and the number of meters of the polyurethane directly buried insulation pipe introduced by the polyurethane insulation pipe manufacturer.
