Details of 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 -
Steel pipe welding defects and causes
Welding is a key task in the construction of large-scale installation projects. Its quality and efficiency directly affect the safe operation and manufacturing period of the project. Due to the different levels of technical workers, the welding process is uneven and prone to many defects. The typ...Read more -
Characteristics, application fields, construction and storage of epoxy resin anti-corrosion steel pipe
Characteristics of epoxy resin anti-corrosion steel pipe: good durability, the paint film after epoxy resin curing is tough and water-resistant, and the coating film is non-toxic and does not pollute water. Strong adhesion, the paint film has good adhesion. Excellent anti-rust and water resistanc...Read more -
Other methods of extending hot-processed steel pipes
Due to the limitations of billet conditions and the extension capacity of the piercing machine, the size and accuracy of the rough pipe after perforation cannot meet the user’s requirements. The rough pipe needs to be further processed. There are many methods for hot-processing and extendin...Read more -
Decarburization of steel pipe surface during heat treatment and its prevention measures
Decarburization is the phenomenon in which the carbon content on the surface of a steel pipe decreases during heat treatment. The essence of decarburization is that the carbon atoms in the steel pipe react with the furnace atmosphere such as hydrogen or oxygen at high temperatures to generate met...Read more -
Is the passivation layer of precision stainless steel pipe corrosion-resistant
Precision stainless steel pipes are widely used. Some industrial equipment and production machinery working in harsh environments have very high requirements for pipe fittings because the acidity, alkalinity, or corrosive salts in the environment will threaten their lifespan; then, many people wi...Read more
