The rated pressure applicable to flexible steel tubing conforms to the ANSI classification by applying a flexible steel conduit to the old pipe, using api17j classification methods and materials to protect the bottom of the pipe from external influences. The design criteria for onshore flexible steel pipes deviate slightly from API standards and rank 600 equals 10.
It often happens that pipelines are forced to shut down and even stop due to corrosion. Flexible Steel Conduit The tests were carried out in accordance with the requirements of the apirp17b and reduced the damage to the environment and ensured the transfer of tension and pressure loads to the structure of the tube. The design of the terminal accessory can satisfy the integrity of the maintenance structure.
Flexible steel conduit has a four-layer structure flexible casing can be easily bent without affecting the continuity of the Tube objects, Flexible Steel Conduit tension and damage limits are within the scope of the specified, the pressure, 17K and rp17b, the most internal layer is extruded thermoplastic tube.
The design basis of offshore flexible steel conduit is api17j, which plays a sealing role in the transmission of liquid. 3MPa, it has the ability to withstand prolonged exposure to ultraviolet radiation. 89MPa; level 400 equals 6.15MPa, such as Level 300 equals 5. Flexible Steel Conduit The outer layer is the thick external shield which is extruded, and can exclude external electrostatic.
