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 -

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 -
Importance of Right Filler Metal for Welded Steel Pipe
In the welding process of large welded steel pipe, we should pay great attention to the melted region of the work piece and form a molten solder, because the melted region is the connection of cooling and solidifying the material after the pool is formed. Usually, the pressure is required by lar...Read more -
What is Structural Tubing
Most people don’t even notice structural tubing, but it is an integral part of everyday life for many people. This sturdy alternative to solid steel is used in an impressive array of industries and products, from shopping carts to hand rails to truck bumpers. These tubes come in many shapes...Read more -
Zinc coating thickness
Zinc coating thickness is the surface of the zinc and the total thickness of the zinc alloy coating, expressed in km. Local thickness of the zinc coating, the arithmetic mean of a number of basic measuring surface as required by law the measured magnetic coating thickness measurement or coating m...Read more -
Carbon steel pipe welding
Generally, carbon steel pipe has a good welding ability. carbon steel pipe welding means a metal material in some welding under the process conditions, the ability to obtain high-quality welded joints. As long as the right choice for mild steel, welding materials (electrodes) and the welding proc...Read more -
