There are various grades of steel pipe, and the specifications of each grade are not the same, among which SCH40 indicates the thickness of the pipe, and the thickness of the pipe will increase with the increase of the number, while CS represents the material of the product is carbon steel.
What is SCH40 carbon steel pipe?
SCH40 carbon steel pipe is the most common pipe specification, it is a good pipe, it can be galvanized, but it does not necessarily have to be galvanized, it is usually used in water and gas lines, but also can be used in places that need decoration and support.
SCH40 carbon steel pipe features:
API 5L Grade B: This is another commonly used grade of No. 40 steel pipe, mainly used in the oil and gas industry. It has a minimum yield strength of 35,000 psi and a minimum tensile strength of 60,00psi.
SCH40 carbon steel pipe main applications:
Pipeline: Used to transport water, gas, oil and other fluids, especially in medium pressure systems, such as building water supply and drainage pipelines and industrial gas pipelines.Chemical processing: Used in chemical factories to transport acids, alkalis and other corrosive chemical components, and can also be used to transport other substances in corrosive environments.
