5mm Stainless Steel Composite Material

Double-Sides Stainless Steel Composite Material With Thickness 5-30mm For Pipe, Tube, Plate



Product Introduction:

Double sided stainless steel clad steel pipes are hot-rolled using carbon steel as the intermediate base and stainless steel as the inner and outer cladding through a special composite process. It is characterized by high mechanical strength, strong resistance to extrusion and common impact, dual use of 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 water supply, nuclear power plants, thermal power plants, chemical enterprises, oil and gas transportation, and other fields.
Double-sided stainless steel composite materials are mainly made into water pipelines (304 stainless steel inner and outer cladding) and chemical pipelines (316L and 2205 stainless steel inner and outer cladding). The pipe diameter is 150-1600mm, and the pipe wall thickness varies from 5-30mm. The variety and thickness of the stainless steel cladding inside and outside the composite steel pipe can be customized according to customer requirements.

Pipe Material Comparison 





Composite method









Lined with stainless steel

Composite steel pipe







Mechanical complex


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.




Double-sided stainless steel

Composite steel pipe






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.
