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 -
