Shandong Liaocheng Polygram steel company to provide you with the relevant information needed steel pipe inspection: Different materials have different test methods, such as steel (divided carbon steel, alloy steel, stainless steel, etc.), sheet metal, steel, non-ferrous materials, its detection methods and content are different, the relevant inspection requirements of various materials in both standard and can be tested in accordance with the requirements of the standard, contracts, technical agreements, then there are configuration detection tools, test equipment, etc. and also restricting the test implementation, is to verify the arrival of seamless steel tubes, for example, said simply: 1, check the packaging: for damage, compliance with contracts, technical agreements and standards. 2. Check mark: Flag content is complete, complete Tianjin Steel Plant, flag is clear and firm. 3, check the technical documents: whether the certificate, quality certificate and check specifications and lot number is consistent with the physical. 4. Check the appearance of the pipe (1) and external surface shall have a crack pipe, folded, rolled off, separation, hairline and scarring defects; (2) at both ends of the tubes shall be cut at right angles, and clear the glitch; ( 3) Pipe bending and not have severe deformation phenomena. (4) steel surface may not have serious corrosion phenomenon, the general corrosion should clean repaired. 5, check the pipe diameter, wall thickness, length, etc. should be consistent with the standard geometry, contract requirements. 6, roundness and wall thickness of pipe inspection uneven, and should not exceed 80% of the diameter and wall thickness tolerances. 7, if the conditions can be chemical composition, mechanical properties of detection. 8, if the conditions, according to the contract, the technical information, can be detected microstructure.
