Rectangular carbon steel pipe overview
Rectangular tube, also known as square tube, is a type of hollow strip steel that has the same bending and torsional strength and is relatively light in weight. Therefore, it is widely used in the manufacturing of mechanical parts and engineering structures. There are many materials used to make rectangular tubes, which can be divided into two categories: plain carbon steel and low alloy:
1. Plain carbon steel rectangular pipes: including S235, S275, S355, S420, S460, SS400, 20 # steel, 45 # steel, etc.
2. Low alloy rectangular tube: including Q345, 16Mn, Q390, ST52-3, etc.
1. Rectangular carbon steel pipe standards
EN10219，EN10210，ASTM A500，ASTM A501，ASTM A53，ASTM A106，JIS G3466,GB/T6728，GB/T3091，GB/T3094，etc
2. Dimensional standard for rectangular carbon steel pipe
The size of carbon steel square pipes should comply with the standards of the country and region required by the customer, generally specified according to parameters such as outer diameter, wall thickness, length, etc.
3. Processing standards:
The processing of carbon steel square pipes should comply with the national standards required by the customer, and generally use processes such as cold drawing, cold rolling, and hot rolling for processing.
4. Surface treatment standards:
The surface treatment of rectangular carbon steel pipes should comply with the relevant standards required by the customer, and generally adopts methods such as painting, galvanizing, and plastic spraying to improve the corrosion resistance and aesthetics of the product.
