Decarburization and Oxidation of Spiral Steel Pipe
When the spiral steel pipe (SSAW) is heated, the iron, alloy, and elements on the surface of the steel react with oxygen, carbon dioxide, and water vapor in the medium to form an oxide film. The pheno...
Comparative Analysis of Seamless Casing Pipe and ERW Casing Pipe
According to the manufacturing method, the steel pipe can be pided into two categories: seamless steel pipe and welded seam steel pipe. Among them, ERW steel pipe is the main variety of welded steel p...
Classification of Seamless Pipes for Low and Medium Pressure Boilers
Seamless steel pipes are pided into two types: hot-rolled and cold-rolled (dial) seamless steel pipes.
Hot rolled seamless steel pipes are pided into general steel pipes, low and medium pressure boil...
Different Forming Methods for Industrial Production of Large Straight Seam Pipes
The industrial production of large straight seam pipes (LSAW steel pipe) can be pided into the following types according to different steel pipe forming methods.
1. UOE process
The so-called "UOE" pro...
Differences between Precision Steel Pipe and Small Diameter Steel Pipe
Precision steel pipe is a kind of high-precision steel pipe raw material after cold drawing or hot rolling. Because there is no air oxide layer on the inner and outer walls of precision steel pipes, i...
Differences Between Seamless Pipe and ERW Pipe
Casing pipe and Tubing pipe made to API specifications uses seamless or electric-weld processes. Seamless pipe is defined as a wrought steel tubular product made without a welded seam. It is manufactu...
Quality Inspection of Spiral Steel Pipe
Spiral steel pipes should be subjected to mechanical performance test, flattening test and flaring test before leaving the factory, and must meet the requirements of the standard. The quality inspecti...
Analysis of Cutting Heat Treatment of Seamless Steel Pipe
The seamless steel pipes we use every day need to be done-some cutting treatment and heat treatment. What are the reasons for seamless steel tubes to be treated?
Seamless steel pipe cutting treatment...
Anticorrosion Technology of Buried Petroleum Pipeline
As a carrier of oil and gas transmission, buried oil pipelines are a link connecting upstream and downstream (analyzed by backward status), and are important facilities for surface engineering. Becaus...
ERW Pipe vs Seamless Cost
Seamless steel pipes have a hollow section and are used in large quantities as pipelines for conveying fluids, such as pipelines for conveying oil, natural gas, gas, water and certain solid materials....
