The structure of flexible steel pipe has four layers, the most internal layer is extruded thermoplastic pipe, the middle two-layer liner is filled with carbon polyethylene pipe, with long-term resistance to ultraviolet radiation capacity. Finally, the external shield is extruded to protect the bottom of the pipe from external influences. Flex Steel Conduit And Fittings Standard flexible steel pipe suitable for the nominal pressure to meet the ANSI classification, flexible steel pipe design standards slightly deviate from the API standards, the use of API 17J classification methods and materials, its pressure, Flex Steel Conduit And Fittings tensile and destruction limits are in line with the provisions. The test is based on the API RP 17B requirements.
Flexible steel pipe design to meet the integrity of the maintenance structure to ensure that the internal and external extrusion molding layer sealing requirements, and to ensure that the tension and pressure load transfer to the pipe structure.
The pipeline is forced to shut down and even stop the operation is often occurred, the use of flexible steel pipe repair technology can solve this problem, the method is a flexible steel pipe set to the old pipe. Flexible steel pipe Repair technology can not only save costs, Flex Steel Conduit And Fittings but also reduce the damage to the environment.
The flexible steel pipe plays a sealing role in the transmission of liquid; the middle two-layer liner is filled with carbon polyethylene tubing, Flex Steel Conduit And Fittings which has the ability to withstand prolonged exposure to ultraviolet radiation and can exclude external static. The outer layer is a thick external shield that is extruded to protect the bottom of the pipe from external influences. The nominal pressure of flexible steel pipe is in accordance with ANSI classification, such as level 300 equivalent to 5.15MPa; Flex Steel Conduit And Fittings grade 400 is equivalent to 6.89MPa; grade 600 equals ten. 3MPa.
