Product Introduction:
The double-sided stainless steel clad steel pipe is made of double-sided stainless steel clad steel plates. Double sided stainless steel clad steel plate is hot-rolled with carbon steel as the intermediate base layer and stainless steel as the inner and outer cladding layer through a special composite process.
The main products include water transmission pipelines (inner and outer cladding of 304 stainless steel) and chemical pipelines (inner and outer cladding of 316L and 2205 stainless steel). The pipe diameter is 150-1600mm, and the pipe wall thickness varies from 5-30mm. The variety and thickness of the inner and outer stainless steel cladding of composite steel pipes can be customized according to customer needs.
Double sided stainless steel composite pipe has high mechanical strength, strong resistance to extrusion and co shock, dual purpose cold and hot, corrosion resistance, and no pollution. Due to its advantages such as almost no maintenance during use and a service life of up to 100 years, it is increasingly widely used around the world and can be widely used in water supply, river crossing water supply, nuclear power plants, thermal power plants, chemical enterprises, oil and gas transmission, etc.

The disadvantage is that : (1) Due to the low bonding force of the inner and outer layers, as a long-term transportation pipeline, due to the different thermal expansion coefficients inside and outside, the thermal stress caused by temperature changes is concentrated on the welded part of the pipeline joint, resulting stress corrosion problems that cannot be overcome; (2) The composition difference between the inner prefabricated thin-walled tube and the base material leads to Increased risk of electrochemical corrosion; (3) Once a corrosion leak occursIt cannot be repaired by welding, and the corrosive liquid will spread along the entire bonded layer gap in a large area; (4) The non-destructive testing of welds is complex,need to useX-Rays(RT) detected twice, after completing the second welding and the cover welding, it can be ensured that there are no defects in the weld; (5) Under high temperature environments, due to the difference in expansion coefficient between carbon steel and stainless steel layers and the presence of interlayer gases, the inner cladding layer is unstable and bubbles occur; (6) Lined welded pipe is in welded and cold-worked state, so that reduces its corrosion resistance; (7) Mechanically bonded structure making it cold and hot processing cannot be used to manufacture elbows, tees and other accessories.

The advantages of overcoming the above disadvantages of lined stainless steel composite steel pipes, include: (1) Can utilize tubing On-site production of small-angle elbows; (2) Can open holes at any position to connect branch lines or instruments; (3) once the pipeline’s if a point is damaged and leaks, only the point needs to be repaired; (4) Weld seam non-destructive testing is simple, only need to only once after cover welding; (5) High bonding strength, strong oxidation resistance and high corrosion resistance, cold and hot processing can be used, and the elbow accessories are complete.
