Easy Installation Of Flexible Steel Pipe Transportation

- Aug 23, 2017 -

The flexible steel pipe has a four-layer structure, the most inner layer is extruded thermoplastic pipe, in the transmission of liquid from the sealing effect; the middle two layers of lining with carbon filled polyethylene tube, it has a long-term resistance to ultraviolet radiation , Flex Steel Conduit And Fittings And can exclude external static electricity. The outermost layer is an extruded thick outer shield for protecting the bottom of the tube from external influences. Standard flexible steel pipe for the rated pressure in line with ANSI classification, Flex Steel Conduit And Fittings such as the level of 300 equivalent to 5.15MPa; grade 400 is equivalent to 6.89MPa; grade 600 is equivalent to 10.3MPa.

Flexible steel pipe design standards slightly deviate from the API standard requirements, the use of API17J classification methods and materials, the pressure, Flex Steel Conduit And Fittings tension and damage limits are within the specified range. The test was carried out according to the requirements of APIRP17B.

Flexible pipe fittings are designed to meet the integrity of the structural structure, Flex Steel Conduit And Fittings to ensure that the inner and outer extrusion molding layers are sealed, and to ensure that the tension and pressure loads are delivered to the tube structure. The samples of the terminal fittings were subjected to blasting and axial tensile tests.

Material properties of flexible steel tubes

Although the flexible pipe according to the different materials have many different classification, but its common are:

1, strong corrosion resistance. Glass fiber reinforced plastic pipe, rubber material corrugated pipe is a non-metallic materials, corrosion resistance; Flex Steel Conduit And Fittings metal coil corrugated pipe galvanized layer also has good corrosion resistance.

2, the pipeline is flexible and good. Glass fiber reinforced plastic sand pipe is made of glass fiber winding, in order to increase the middle of the sandwich sand; rubber (or plastic) material bellows is hot cast molding, some varieties in the middle with metal wire skeleton, metal bellows is book metal Crimping, the axial stiffness of these pipes is very good, the stiffness value increases with the wall thickness of the pipe. Flex Steel Conduit And Fittings Compared with the reinforced concrete pipe, the axial large deformation will not damage the pipeline itself, the maximum axial allowable deformation of the pipe length of 1%, the maximum radial allowable deformation of 5%, (manufacturers to provide value) can be well adapted Weak foundation. So it can also be called flexible steel pipe.

3, transport installation is simple. Flex Steel Conduit And Fittings Pipeline production length of 6 to 8 meters, or even longer, less interface, so the installation period is short.

4, the interface construction time is short. The use of mechanical, physical, chemical seal instead of using concrete wiping seal, and some even do not make concrete base, eliminating the need to wait for the time of life of concrete.
