UNS S31803 Welded Pipes are distinguished by their dual-phase microstructure, composed of approximately 50 % austenitic and 50 % ferrite. Our Welded Pipes have a smooth finish and are durable as ASTM A790 UNS S31803 Welded Pipes. ASTM A790 UNS s31803 Welded Pipes have a yield strength that typically exceeds that of austenitic stainless steel. Sizes range from 1/8′′ to 6′′ with Plain End, Beveled End, and Threaded End.

These ASTM A790 UNS S31803 Welded Pipes are the most commonly available duplex grade. They should not be used at temperatures above 300 degrees Celsius due to embrittlement. ASTM A790 UNS S31803 Welded Pipes are used in a variety of industries including chemical, petrochemical, marine, oil and gas, and transportation. We test these pipes before they are sent to the clients so that we don’t deliver damaged pipes. This stress-relieving operation is carried out at temperatures ranging from 525 To 600 degrees Celsius, and as a result, resistance in harsh environments has increased. Every employee here is held accountable for their quality of work.

Furthermore, we are committed to improving our employees’ technical and operational capabilities through training and continuous technical quality awareness. We have achieved high quality due to the dedication of our professionals.

We specialize in ASTM A790 UNS S31803 Welded Pipes Exporting in Turkey, Egypt, Singapore, Malaysia, Indonesia, Jordan, South Africa, Oman, Qatar, and Italy.
