China leading manufacturers and suppliers of Seamless Steel Pipe, and we are specialize in Seamless Stainless Steel Pipe, Seamless Carbon Steel Pipe, Seamless Steel Tube etc.
The carbon steel seamless pipe is produced by rolling, drawing, squeezing, and punching. As its name suggests, it has no seams on the surface. Compared with solid steel, steel pipe is lighter under the same compressive strength and tensile strength. Therefore, it is widely used in oil, chemical, shipping, automobile, aviation, energy, construction, military, and other industries.
Common technical standards: ASTM A106 Grade B, ASTM A53 Grade B, API 5L Grade B
The ASTM A106 Grade B and ASTM A53 Grade B are the most commonly used American standards for carbon steel seamless pipe. They are applicable to pipes for high temperature services as well as pipes operating below 350℃ for pressure piping, pipeline and general purposes. Products conforming to ASTM A106 are processed by cold drawing or hot rolling.
