A671 Pipe is a low temperature pipe specification that can have different material grades under it. The pipes are created by filler material added electric fusion welding. Multi Metals (India) is a leading manufacturer and supplier of the A671 Pipe products in various dimensions and grades for use in various application types. The pipe is made from a pressure vessel quality plate. The pipes are then to be undergone with several tests such as transverse and tension tests.

The ASTM A671 Efw Pipes vary in grades of steel such as CA55, CB60, CD, CH and so on with numerous chemical composition differences and mechanical property deviations. All the pipes are electric fusion welded in this specification. As one of the leading A671 Pipe Manufacturers we produce the pipes ranging from class 10 to class 42. There are schedules 20 through XXS and heavier upon request. The wall thicknesses of the pipes can range up to 250mm and the nominal bore size ranges from 16 inches to 100 inches.

The ASTM A671 Pipe Suppliers produce the pipes in different lengths starting from 5m to 12m as single random, double random and cut to length sizes. The pipes can come with different pipe ends to be fitted onto different components. The pipe ends vary as plain, beveled and coupling ends. Our ASTM A671 Pipe Price is very competitive to the market price and you can order any size of order with us for better pricing. Please contact us for detailed information on the ASTM A671 Carbon Steel Pipe and the prices.
