Quality inspection method of seamless steel pipe: (1) Geometric specification detection of seamless steel pipes The diameter, thickness, bending degree, and length of the seamless steel pipe can be inspected on the inspection table with external calipers, vernier calipers, bending level rulers, and length meters. For external opening diameter, thickness and length, automatic specification inspection equipment (such as automatic…
Read MoreGenerally, manufacturers have the following requirements for their quality when producing seamless pipes. 1. Ingredients. It clearly stipulates the components of hazardous chemical molecules As, Sn, Sb, Bi, Pb and vapor N, H, O, etc., in order to improve the uniformity of the components in the steel and the purity of the steel, and reduce the non-metallic material parameters…
Read MoreWhat are the factors that affect the quality of American Standard seamless tubes? 1. Temperature Temperature is the main factor affecting the quality of American Standard seamless steel tubes. First of all, the uniformity of the heating temperature of the tube blank directly affects the wall thickness uniformity and inner surface quality of the perforated capillary, which in turn…
Read MoreIn the process of purchasing seamless steel pipes, we often encounter several steel pipe length terms. If we cannot fully understand these terms, hidden dangers will often be buried in the signing of the contract, which will bring inconvenience or heavy losses to our later use. Therefore, we should fully understand these terms in the procurement process and confirm…
Read MoreThere are many reasons for longitudinal cracking of seamless pipes, both material and process reasons. Taking the thick-walled seamless steel pipe as an example, if the thick-walled seamless steel pipe has poor plasticity or poor annealing, the probability of longitudinal cracking will increase, but the fundamental reason is that the residual stress of the cold-drawn thick-walled seamless steel pipe…
