Product Overview
Carbon Steel Seamless Steel Pipe is a high-performance tubular product manufactured by hot rolling or cold drawing without a longitudinal weld seam. Compared with welded pipe structures, the seamless design provides reliable mechanical strength and stable performance for high-pressure and demanding industrial applications. It is widely used for fluid transmission, pressure equipment, boiler systems, hydraulic applications, and chemical processing pipelines.
This product covers a wide range of carbon steel, low-alloy steel, and low-temperature seamless grades, including 10#, 20#, 45#, Q355B, 16Mn, ASTM A106, ASTM A53, ASTM A333 low-temperature grades, P235GH, P265GH, 16Mo3, and 13CrMo45. It is manufactured according to international standards including GB/T 8163, GB/T 699, ASTM A106, ASTM A53, ASTM A333, EN 10216, and JIS G3454.
With an outer diameter range of 6–720 mm and wall thickness from 1–100 mm, Carbon Steel Seamless Steel Pipe supports different pressure requirements through complete Schedule options such as Sch20, Sch40, Sch80, Sch160, and XXS heavy wall series. Standard lengths include 6 meters and 12 meters, with customized processing available for different project requirements.
The pipe can be further processed with threading, end beveling, hot-dip galvanizing, 3PE coating, and coal-tar epoxy anti-corrosion treatment. It is suitable for industries including chemical plants, power stations, pressure vessel manufacturing, engineering projects, and other applications requiring high-pressure, high-temperature, or cryogenic service capability.
