ASTM A672 EFW Pipes

ASTM A672 pipes are electric fusion welded carbon steel pipes made using pressure vessel quality plates. These pipes are suitable for high-pressure applications at both atmospheric and lower temperatures. Popular grades like ASTM A672 Gr B60 Class 12 are known for their strength and durability. The A672 pipe material is perfect for projects requiring durability and reliable performance because it is easy to fabricate. These pipes are a popular option in many industries, since they come in a variety of sizes, thicknesses and large diameters.

Application of ASTM A672 EFW Pipes

● Power plants: Especially in boiler and steam systems, these systems require piping that is resistant to high temperatures and pressures for the safe transfer of steam and hot water.
● Refineries: In the refining process, piping is needed to efficiently transfer crude oil and products between different processing stations, and these pipes must be able to withstand the high temperatures and chemical attack of the process.
● High-Pressure Transmission Lines: High-pressure transmission lines are used to transport high-pressure fluids or gases such as natural gas and oil.
● Industrial Pressure Systems: In manufacturing and other industrial applications, many pressure systems require reliable high-pressure piping to ensure production safety and efficiency.
