The difference between precision ...
Precision seamless steel pipe is a kind of high-precision steel pipe after cold drawing or hot rolling. Due to the advantages of precision seamless steel pipe on the inner and outer walls of precision seamless steel pipe, high pressure and no leakage, high precision, high smoo...
What is a petroleum steel pipe?
What is a petroleum steel pipe? The petroleum steel pipe is a long steel with a hollow section and no joints around, and the petroleum cracking pipe is an economical section steel. Role: Widely used in the manufacture of structural parts and mechanical parts, such as oil drill...
How to identify thick-walled seam...
1. The shoddy thick-walled seamless steel pipe is prone to folding. Folding is a variety of fold lines formed on the surface of thick-walled seamless steel tubes, which often extend throughout the longitudinal direction of the product. The reason for the folding is that the in...
What types of oil casings are there?
What types of oil casings are there? Different types of casing used in oil extraction: Surface oil casing protects the well from contamination by shallow water and shallow gas, supports wellhead equipment and maintains the weight of the other layers of the casing. The technica...
What is the use of oil casings?
What is the use of oil casings? Oil casing is the lifeline for maintaining oil well operations. Due to different geological conditions, the state of the downhole is complicated, and the combined action of tension, compression, bending and torsion stress acts on the pipe body, ...
