Effect of cooling water through the pipe welding process performance
Welded square tube water cooling technology: controlled cooling device installed after the finishing mill, the use of rolling after finishing fast deformation, immediately rapidly cooled by welded square tube deformation induced phase transition, the control bars under high temperature grain grow...Read more -
Galvanized coating on pipe surface
Galvanized coating has a number of characteristics that make it a well-suited corrosion protective coating for iron and steel products in most environments. Th excellent field performance of Galvanized coating results from its ability to form dense, adherent corrosion product films of corrosion c...Read more -
China Line steel pipes
Line steel pipes are hollow tubes used for long distance pipelines in transporting combustible liquids and gases which can be mostly seen in industrial frameworks of energy distribution. These pipes are durable due to its high corrosion resistance property and thus can be also used for constructi...Read more -
Black Pipe vs Galvanized Pipe
Black and galvanized pipes are commonly used steel pipes. Pipes are needed in every home and commercial building because of need of water and gas. These two are basic necessities for everyone and as such every building requires pipes to be run from main pipelines. The two most commonly used types...Read more -

（1）Seamless steel pipe or seamless steel tube for pipeline project ,oil and gas transportation （2）LSAW steel pipe or SAWL steel pipe for Gas pipeline or oil pipeline or pipe construction （3）Spiral welded steel pipe or SAWH steel pipe or SSAW steel pipe or spirally steel pipe for water sys...Read more -
Different Grades of API Steel Pipes
API steel pipe is most commonly made by using a duplex stainless steel or a grade of iron that has higher nickel content, such as a six percent of Mo material or high nickel alloys. Ferrite stainless steels are very resistant to API steel pipe but grades may vary with equivalent pitting resistanc...Read more -
Anti-corrosion surface treatment process of spiral pipe
Typically the metal surface will be accompanied by dust oxide corrosion layer of oil contaminants salt or old paint. Dense oxide layer is an oxide layer formed in the forging steel produced by high temperature, usually attached relatively firmly, but more brittle than the steel itself, and the ca...Read more -
The advantages of galvanized steel pipe
The advantages of galvanized steel pipe are following below: 1. The entire surface of the steel is to be protected, both in the inside the recess at the tube member, or any other coating is difficult to enter the corner, and solubilized zinc are easily uniform coverage. 2. Galvanized layer hardne...Read more -
Carbon steel piping passivation

Welded Steel Pipe Usages and Recommendations
Chain vises are one of the most important welding technologies and tools and they are made with jaws for holding welded steel pipe. In fact, jaws are engineered so they can provide holding power without causing any damage to the pipe. However, we should never use dry granular calcium hypochlorite...Read more -
Seamless steel pipe piercing theory
In the seamless steel pipe production, the role of the perforation process is to wear a solid hollow tube capillary. As a first step of perforated metal deformation, wear thick pipe wall thickness, length is shorter, poorer quality of inner and outer surfaces, so called capillary. If there are so...Read more
