In order to ensure the quality of seamless steel pipes, Conson Metal Materials has always insisted on controlling the following aspects:

a. Raw materials: Use high-quality steel billets to ensure that there are no defects, bubbles, or cracks on the surface. At the same time, it is necessary to ensure that the chemical composition and mechanical properties of raw materials meet standard requirements.

b. Production process: Strictly control each process in the production process to ensure that the quality of each process is stable and reliable. Especially during the piercing and rolling processes, temperature and pressure must be strictly controlled to avoid cracks and deformation.

c. Dimensions: Conduct dimensional inspection on finished steel pipes to ensure that their diameter and wall thickness meet standard requirements. Special measuring instruments can be used for measurement, such as micrometers, wall thickness measuring instruments, etc.

d. Surface quality: Conduct surface quality inspection on finished steel pipes, including surface roughness, presence of cracks, folding and other defects. Detection can be done using visual inspection or specialized testing instruments.

e. Metallographic structure: Conduct metallographic structure testing on the finished steel pipe to ensure that its metallographic structure meets standard requirements. Generally, a microscope is used to observe the metallographic structure and check whether there are microscopic defects.

f. Mechanical properties: Mechanical properties of finished steel pipes are tested, including hardness, tensile strength, yield strength and other indicators. Tensile testing machines and other equipment can be used for testing.
