Five carburizing defects and prevention methods of heat treatment of steel pipes
1. Too high carbon concentration A. Causes and hazards If the carburizing is heated sharply, the temperature is too high, or a new carburizing agent is used during solid carburizing, or too much strong catalytic agent is used, the carburizing concentration will be too high. With the high carbon c...Read more -
Quality problems in the production process of seamless steel pipes – quality defects in steel pipe sizing (reduction) and their prevention
The purpose of steel pipe sizing (reduction) is to size (reduce) the rough pipe with a larger diameter to the finished steel pipe with a smaller diameter and to ensure that the outer diameter and wall thickness of the steel pipe and their deviations meet the relevant technical requirements. The q...Read more -
Uneven thickness of anti-corrosion coating on spiral steel pipe and its treatment
Spiral steel pipe is mainly used as fluid pipe and piling pipe. After the steel pipe is made, if it is used for water transportation, it will generally be treated with anti-corrosion on the inner or outer surface. The general anti-corrosion includes 3PE anti-corrosion, epoxy coal tar anti-corrosi...Read more -
