Carbon Steel Seamless Pipes are widely used in various industries due to their excellent strength, durability, and cost-effectiveness. They are commonly used to transport fluids and gases such as water, oil, and natural gas.
The seamless steel pipe is made of perforated whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes.
ASTM A53 ASME SA53 Black Carbon Steel Seamless Steel Pipe are mainly used as petroleum geological drilling pipes, cracking pipes for petrochemical industries, boiler pipes, bearing pipes and high-precision structural steel pipes for automobiles, tractors and aviation.The production of our seamless pipes is tightly regulated and all of the pipes we stock have been fully tested to international standards to ensure we only supply the highest quality products.
