Product Description
Carbon steel pipe is the most commonly used material for process piping. It has the advantage of wide availability, high strength, and a large array of connection possibilities, for example, screwed, socket-welded, and butt-welded. Steel pipe should be selected for the required strength and durability required for the application and the ductility and machinability required to join it and form it into piping spools. The pipe must withstand the pressure, temperature, and corrosion conditions of the application. These requirements are met by selecting pipe made to an appropriate ASTM or API standard. Carbon steel pipe is used for liquid, gas, and steam services both above- and belowground services. It is not recommended for use in corrosive services but may be used in caustic services.SSAW Steel Pipe | Out diameter:219mm-3620mm |
