Product Details

Description

Natural gas is a very important and common energy, so its transmission is also very important. Gas Pipeline Steel Plate is specially used to make steel for natural gas transmission pipelines. High-grade steel pipes can be used for natural gas pipelines because the strength and toughness of high-grade steel pipes can meet the various indicators of natural gas pipelines. In addition, natural gas pipeline materials are more selective, including steel pipes and cast iron pipes, which should be selected according to the pipeline laying situation. Steel pipes can be selected for high-pressure, medium-pressure, and other gas pipelines, and cast iron pipes can be used for low-pressure gas pipelines.


Gas Pipeline Steel Plate is made by smelting, refining, and rolling processes, with high strength and corrosion resistance. Steel grades are generally X52, X60, X65, X80, etc., and steel pipes of higher grades, such as X100, and X120, are also applicable. Usually, outdoor natural gas pipelines are made of steel pipes, which are also the main materials of natural gas pipelines. The pipes made of our products have strong pressure resistance, certain weldability, and high strength, which can ensure that the gas connection is in place and are not easy to leak.


Delivery condition:

TMCP, hot rolled and normalized, etc.
