Analysis of the causes of transverse cracks on the inner wall of cold-drawn seamless steel pipes
1. Analysis of crack characteristics It can be seen that there are many transverse cracks distributed along the longitudinal direction of the steel pipe. The cracks are arranged neatly. Each crack has a wavy feature, with a slight deflection in the longitudinal direction and no longitudinal scrat...Read more -
Quenching deformation in steel pipe production
1. Residual stress and deformation: When steel is heated to about 450℃, it changes from an elastic body to a plastic body, and plastic deformation is likely to occur at this time. On the other hand, when heated to about above 450℃, the stress disappears due to the residual recrystallization. Ther...Read more -
6 questions about heat treatment deformation of steel pipes
First, the quenching strain has dimensional change and shape change. Quenching strain (distortion) has two types: dimensional change and shape change (deformation). The so-called dimensional change is the dimensional change caused by expansion or contraction caused by phase change during quenchin...Read more -
Uses and packaging and storage of oil casing
First, the use of oil casing Oil casing is a large-diameter pipe that plays the role of fixing the wall or wellbore of oil and gas wells. The casing is inserted into the wellbore and fixed with cement to help the wellbore separate the rock layer and prevent the wellbore from collapsing while ensu...Read more -
