Carbon Steel Seamless Pipe is a weld-free steel pipe produced from solid round billets through piercing, rolling or drawing. It is suitable for fluid conveyance, high-temperature service and structural applications.
Product Description
Carbon Steel Seamless Pipe uses high-quality carbon steel round billets as raw material, with no welding involved throughout the process, giving the pipe body good overall consistency. By manufacturing standard, it can be classified into several categories: ASTM A106 for high-temperature service, ASTM A53 for general fluid conveyance, ASTM A524 for ambient and low-temperature service, and API 5L for line pipe. Common materials include 10#, 20#, Q345B and ASTM A106 Gr.B.

FAQ
Q: What tests are usually required during acceptance inspection of Carbon Steel Seamless Pipe?
A: Routine acceptance includes tensile testing, flattening or bending testing, and hydrostatic testing. Hydrostatic test pressure is usually twice the working pressure and not less than 7.0 MPa, with sufficient holding time for inspection.
Q: What should be noted during transportation and storage of this product?
A: Protective caps should be installed on pipe ends to prevent damage during transport. Wooden or plastic dunnage should be used during stacking, with at least three rows of dunnage perpendicular to the pipe body between layers to avoid direct contact. Stack height should not exceed 3 meters, and the stack should be at least 46 cm above ground for moisture protection.
Q: What service conditions is ASTM A524 suitable for?
A: ASTM A524 covers seamless carbon steel pipe for ambient and low-temperature service. The pipe shall be killed steel, normalized or normalized and tempered, suitable for sizes from NPS 1/8 to 26.
