  • Type of Carbon Steel Pipe Coating

    Bare Pipe : A pipe is considered bare if it does not have a coating adhered to it. Typically, once rolling is complete at the steel mill, the bare material is shipped to a location designed to protect or coat the material with the desired coating (which is determined by ...

  • What is RHS , SHS and CHS ?

    The term RHS stands for Rectangular Hollow Section. SHS stands for Square Hollow Section. Less known is the term CHS, this stands for Circular Hollow Section. In the world of engineering and construction, the acronyms RHS, SHS and CHS are often used. This is most common in the United Kingdom and...

  • hot-rolled seamless steel pipe and a cold-rolled seamless steel pipe

    Cold-rolled seamless steel pipes are often of small diameter, and hot-rolled seamless steel pipes are often of large diameter. The accuracy of cold-rolled seamless steel pipe is higher than that of hot-rolled seamless steel pipe, and the price is also higher than that of hot-rolled seamless steel...

  • difference between pre-galvanized steel tube and hot-galvanized steel tube

    Hot dip galvanized pipe is the natural black steel tube after manufacturing immersed in the plating solution. The thickness of the zinc coating is affected by a number of factors, including the surface of the steel, the time it takes to immerse the steel in the bath, the composition of the steel,...

  • Carbon steel

    Carbon steel is a steel with carbon content from about 0.05 up to 2.1 percent by weight. Mild steel (iron containing a small percentage of carbon, strong and tough but not readily tempered), also known as plain-carbon steel and low-carbon steel, is now the most common form of steel because its pr...

  • ERW, LSAW Steel Pipe

    Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. The production process of straight seam steel pipe is simple, with high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally hig...

  • what is ERW

    Electric resistance welding (ERW) is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. Electric resistance welding is widely used, for example, in manufacture of steel pipe.

  • SSAW Steel Pipe vs. LSAW Steel Pipe

    LSAW Pipe (Longitudinal Submerged Arc-Welding Pipe), also called SAWL pipe. It is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, ...

  • Galvanized Steel Pipe vs. Black Steel Pipe

    Galvanized steel pipe features a protective zinc coating that helps prevent corrosion, rust, and the buildup of mineral deposits, thereby extending the pipe’s lifespan. Galvanized steel pipe is most commonly used in plumbing . Black steel pipe contains a dark-colored iron-oxide coating on its ent...
