Factors affecting strength of steel pipe

Manufacturer of steel pipe like seamless steel pipe, ERW steel pipe, LSAW steel pipe, would make each kind of product as artwork. And we all know it is uneasy if the work don’t brilliant for engineering project. So even for steel pipe’s strength, we would like to have patience for researching it. First of all, the strength of the steel pipe relies on alloy composition. We should follow the high quality principle to add the alloy composition instead of violating it. All composition would include seamless and seamed steel pipe for substantially uniform strength alloy and its heat treatment. We can make it according to relative standard of the steel pipe. What’s more, tensile test and three-dimensional vibration test would be necessary before selling. We all know that tearing of steel pipe joint would happen almost in away from the welding spot or the heating place. Thus we have equipment test such as Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test, Blow Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, X-ray Test and so on.
