Each kind of test measurement such as Technical Properties (Flattening Test, Bending Test, Blow Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, X-ray Test would be necessary for guarantee of the high quality of steel pipe like seamless steel pipe, galvanized steel pipe. There are some characteristics for visual inspection of non-destructive testing: 1.Weld surface defects test: surface cracks would be the first step for check of the steel pipe and then the impermeability and weld quality of the leak. 2.Detailed exam for raw material for steel pipes production, such as the surface cracks, peeling, cables, scratches, dents, bumps, spots, corrosion and other defects. 3.Cavity detection. This test would carry out according to the engineering projects demand and the engineers requirement. 4. Additional material inspection. Inspect the product for dust, foreign matter and other residues in the cavity.
No matter which kind of steel pipe, seamless steel pipe, or ERW steel pipe, or straight seamless welded pipe, there is the pipe forming demands for them in order to have the best quality when they applied in various engineering project. Here is the list for welded steel pipeâ??s joint surface demands for manufacture and this would lead customers to figure out the better steel pipe too. 1.It is not allowed for cracks, pores, slag, lack of fusion, spatter during the production process. 2.Temperature would be controlled strictly. For example, we should figure out the different temperature for surface treatment about Fusion bond Epoxy coating, Coal Tar Epoxy, 3PE, Vanish Coating during the whole production. 3.It is necessary to notice that we should keep the whole temperature must not be lower than the surface of the weld surface of the pipe. For example, some of the welding reinforcement does not exceed 3mm (the maximum width of the weld after the groove). We have to pay high attention to every step during the production process in order to have high quality steel pipes for customers.
