ASTM A671 Grade CC65 EFW Pipe

We are the leading Manufacturers, Suppliers & Exporters of High Quality ASTM A 671 Grade CC 65 Carbon Steel EFW Pipes & Tubes. The steel pipe shall be fabricated from a pressure vessel quality plate of various analysis and strength levels. Several grades and classes of pipe shall be provided. All Pipe is manufactured and inspected/tested to the relevant standards including ASTM, ASME, API. These pipes & tubes is commonly used in oil & Gas, power Plants, boilers, ships etc.

Our A671 specification covers standard requirements for electric-fusion-welded steel pipe with filler metal added, for atmospheric and lower temperatures. The steel pipe shall be fabricated from a pressure vessel quality plate of several analysis and strength levels. Several grades and classes of pipe shall be provided. We Supply Carbon Steel ASTM A671 CC65 CL22 EFW Pipes in ASTM A671 EFW pipes. These ASTM A671 Grade CC65 Pipes come in a variety of sizes, grades and class designations that indicate the testing methods required for a given application. They come in single, double, and cut-to-length. It can be up to 250mm thick. That's why you have to heat the material before you weld it. A671 Grade CC65 Class 22 also needs to be heated and cooled after it's been welded. As long as you don't break it, the material can be strong enough to last for years. It has a minimum yield strength of 240MPa. These ASTM A671 Gr.CC65 Cl.13 and other lower classes have less mechanical strength. This is more than that.
