ASTM A671 Pipe

The a671 cc60 cl22 is a product specification for an electric fusion welded pipe, with added metal fillers. The a671 pipe grades are suited to high pressure applications at lower as well as atmospheric temperatures. The a671 pipe is a carbon-based stainless-steel pipe that is fabricated in pressure quality plate for varying levels of strength.

The a671 pipe material includes 0.24% of Carbon, 0.13% to 0.45% Silicon, 0.79% to 1.30% of Manganese. This carbon-based stainless-steel alloy also contains trace amounts of other minerals. For example, 0.035% of phosphorus and Sulphur can be found in the alloy.

Addition of these elements during the formation of the alloy increases its mechanical properties. The Yield strength of the a671 gr cc65 is about 240 Mpa and the pipe’s tensile strength ranges between 450 Mpa to 585 Mpa.

The pipe ends for the a671 cc70 cl22 can be either bevelled with protective plastic caps on both the ends of the pipe or they could be plain, grooved, cut square. These pipe ends are also available in threaded ending and coupling ends.

The surface treatment of the a671 cc65 cl22 pipe includes a coating with various materials. For example, these pipes can be coated with EP, PE PP, FBE, anti-corrosion oil and black oil paint. The a671 cc60 cl32 could also be varnished or galvanized. Or the pipes could be left bare. Coating the pipes is known to increase their resistance to corrosion.

The applications of the a671 gr cc60 pipe includes industries like ship construction, oil and natural gas, fertilizer, fabrication etc. These pipes aid in the transportation of fluid and gas from the site to the factory.

astm a671 efw pipes undergo several tests like Hydrostatic testing or Ultrasonic examination, Eddy current testing and NDT.  Besides these tests, the a671 gr cc70 pipes physical and chemical properties are inspected.
