Causes and Adjustment of the Uneven Wall Thickness of Steel Pipe
Causes and adjustment of the uneven wall thickness of steel pipes: 1. The causes of uneven wall thickness of the spiral shape are: the uneven wall thickness caused by the adjustment reasons such as the uneven rolling center line of the piercer, the inclination angle of the two...Read more -
The use of OCTG casing
The OCTG casing is a large-diameter pipe that acts to fix the wall or bore of oil and gas oil wells. The casing is inserted into the wellbore and fixed with cement to help the wellbore separate the rock formations and prevent the wellbore from collapsing while ensuring the cir...Read more -
The reasons for the leakage of hot-dip galvanizing of seamless steel pipes
The leakage of hot-dip galvanizing of seamless steel pipes causes and solutions: 1. The surface of the plated parts is not clean (1) The surface of the plated parts contains paint, grease, and soldering iron; it can be polished or scrubbed with relevant solvents. ⑵ iron oxide;...Read more -
