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 -

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
