Manufacturing Process and Application of Seamless Steel Pipe:

Application: Seamless Carbon Steel Pipe is used for conveying gas, water, and petroleum of both the oil and natural gas industries. Besides, people used it for structure purpose and engineering purpose. We can also do hot-dipped galvanizing and widen the use of such pipes. Manufacturing Process: Seamless Carbon Steel Pipe are produced either by cold-drawn or hot rolled, as specified.Hot finished pipe need not heat treated. When hot finished pipe is heat treated ,it shall be heat treated at a temperature of 1200°F or higher. Cold drawn pipe shall be heat treated after final cold draw pass at a temperature of 1200°F or higher.
