What are the Tips for Buying Seamless Stainless Steel Pipes?

As a Seamless Steel Pipe Supplier, share with you. Seamless stainless steel pipes are widely used in fluid transportation, petroleum, chemical, machinery, etc. The manufacturing process on the market is mainly cold-drawn or cold-rolled reinforcement and solution treatment, and the microstructure is mainly austenite shape. Let me share with you 3 tips for buying seamless stainless steel pipes:

Alloy Seamless Steel Tubes

1. Look at the appearance. The stainless steel seamless pipe with high-quality outer surface should be smooth and free of defects such as cracks, wrinkles, scars, etc. The inner and outer surfaces of the passive film pickling steel pipe should be complete, and the steel surface should have obvious and comprehensive product information coding.

2. Measure the size. Relevant technical standards have their own requirements for the length, curvature, out-of-roundness and uneven wall thickness of the steel pipe and the shape of an end. The steel pipe can be placed on a flat ground, and the steel pipe can be rolled to observe the size and changes of the gap between the steel pipe and the ground environment. The two ends of the qualified seamless steel pipe should be perpendicular to the development axis, and the cut should be free of burrs.

3. Check the product quality certificate. By checking the manufacturer’s name, production date, production (furnace) batch number, manufacturing standard, factory inspection items and related test data, inspection special seal and other information on the product quality manual, further confirm whether the selected steel pipe meets the design or relevant technical specifications .

Seamless stainless steel tube or solid steel ingot is made of perforated capillary tube, then the call is made of hot rolled, cold rolled or cold. With a hollow cross-section, it is used to transport large, round steel and solid steel fluid conduits with the same torsional strength compared to the same bending. It is lighter and is an economical cross-section steel. It is widely used in the manufacture of structural components and seamless steel pipes. Mechanical parts, such as drill pipes, automobile transmissions, have bicycle frames and construction steel scaffolding.
