Fluid pipes are a seamless steel pipe generally used to transport oil, natural gas, petroleum, and other utility products at a pressure less than 10 MPa and temperatures below 350ºC. Yuanhua offers a range of fluid pipes in a diameter of 0.25mm-75mm, and in DN6-DN600 specs. Steel grades used in the construction of these pipes include 10, 20 and Q345B.
Standards
GB/T8163-2008, ASTM A53, ASTM A106, DIN 1629
Uses
Fluid pipes are used to transport petroleum, natural gas and water. These steel piping products are commonly seen in large scale pipelines.
