Seamless alloy steel pipe before receiving what will we do?
We will check the appearance and size of the steel pipe and conduct various performance tests, such as ASTM A335 P5, outer diameter 219.1*8.18
Seamless steel pipe is an important building material and industrial material. In order to ensure the product quality of seamless steel pipes, various tests are often required in the production and supply process to ensure that the quality of the pipes meets the standards and requirements. The following are common testing items for seamless steel pipes:
Appearance inspection: The purpose is to check whether the surface quality of the seamless steel pipe is good, such as whether there is rust, oil and other defects.
Size testing: The purpose is to ensure that the size specifications of seamless steel pipes meet the standards and contract requirements.
Chemical composition testing: The purpose is to detect the main elements in the seamless steel pipe to determine that its quality and material meet the relevant standards.
Mechanical properties testing: The purpose is to test the tensile strength, yield strength, elongation and other mechanical properties of seamless steel pipes to determine that their stress properties meet the relevant standards.
Pressure test: By applying a certain water pressure in the tube, test the bearing capacity and pressure resistance of the seamless steel pipe.
Magnetic particle inspection: The purpose is to find a variety of surface and internal defects in seamless steel pipes, such as cracks, inclusions, pores and so on.
Ultrasonic inspection: The defects in the seamless steel pipe are detected by ultrasonic detection instruments to determine the structure and internal quality of the pipe material.
Hardness test: Test the hardness or strength of seamless steel pipes for related processing or welding.
In short, these testing items can effectively test the performance parameters of seamless steel pipes to ensure that the quality and performance of seamless steel pipes meet the standards and contract requirements.
