This is a batch of steel pipes sent by our company to Singapore, which need to undergo strict inspection and audit before delivery to ensure the quality of the goods, which is not only responsible for our customers but also a strict requirement for ourselves.
Appearance inspection: Check whether the surface of the steel pipe is smooth, no obvious depression, cracks or scratches and other defects, whether there is corrosion, oxidation and other phenomena.
Size measurement: measuring the length, diameter, wall thickness and other dimensions of the steel pipe, and comparing with the technical requirements to ensure that the size meets the standard.
Chemical composition analysis: Collect steel pipe material samples, and test whether its alloy composition meets the requirements through chemical analysis.
Mechanical properties test: tensile, bending, impact and other experimental tests are carried out on the steel pipe to evaluate its strength, toughness, impact resistance and other mechanical properties.
Corrosion performance testing: through salt spray testing, corrosion experiments and other methods to evaluate the corrosion resistance of steel pipes.
Welding quality inspection: Visual inspection and non-destructive testing of the welding site to assess the quality and reliability of the weld.
Surface coating inspection: Check the adhesion, hardness and thickness of the coating to ensure that the coating quality is good.
Marking and packaging inspection: Check whether the marking of the steel pipe is clear and accurate, and whether the packaging is intact to ensure that no damage will occur during delivery.
