We manufacture & export ERW steel pipes that are available in various qualities, wall thicknesses and diameters of the finished pipes. While manufacturing ERW steel pipes only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubing possess high strength corrosion resistance, higer deformability, better strength and toughness.

Characteristics of galvanized steel pipes Black and galvanized steel pipes are both made of steel, but galvanized pipes have a zinc coating while black pipes do not. Therefore, galvanized pipes are more expensive and more durable. How does the galvanization protect steel pipes? The zinc of galvanized steel pipes serves as a sacrificial layer. It will rust before the steel beneath it, allowing the integrity of the pipe to remain intact for much longer time than regular pipes. Moreover, even if the zinc layer is scratched or damaged, it can still protect the steel beneath it. How long will galvanized steel pipes last? The thicker your zinc coating, the longer the pipe lasts. The environment also plays a crucial role in determining the pipe’s life span. If the pipes are placed in highly corrosive conditions, they often last from 50 to 100 years. Applications of black steel pipes and galvanized steel pipes Black steel pipes and galvanized steel pipes are the two most common types of pipes used for transporting liquid and gas.
