4 inch carbon steel pipe Material Specifications
ASTM A106 Gr.B is specially for high temperature service. It is the common carbon steel material is mainly applied for liquid transportation of some industries.
ASTM A53 Gr.B Gr.B is on steel grade in this standard, which can be seamless or welded pipes. If as seamless pipe it is similar to A106 Gr.B
API 5L Gr.B is a low steel grade of line pipe, which is specially used for transporting oil and natrual gas.
EN10216 P235GH is for cabon steel seamless pipe for pressure purposes. It is mainly used by European customers.
4 inch carbon steel pipe Applications
The 4 inch carbon steel pipe is commonly used for many industries and fields due to its excellent mechanical properties and low cost. The below are some application examples.
1. Carbon steel pipe is a very important material for transporting the oil and natural gas.
2. Carbon steel pipes can be used for construction and structure project, such bridge, high-rise buildings, road, tunnel and so on for support and transfer load.
3. Carbon steel pipe is used for one part of exhaust pipe, frame and chasis of motor- car industry.
4. Carbon steel pipe can be as one part of the transport system, pressure vessel and hydraulic system of mechanical engineering, which has the bearing capacity and stability.
5. Carbon steel pipe can be applied for chemical industry as the part of transport system, reactor and storage tank. It has corrosion resistance and high temperature resistance.
