The specifications covered are wall thickness, sizes, lengths, schedules, dimensions, standards, etc. In addition, we make the same readily available to various industrialists in custom-made requirements and standards. We are one among the leading companies who are the Duplex Stainless Steel Tube suppliers of the iron and steel industry.
The complete range of ASTM A790/789 S32205 duplex steel stainless pipes at our production unit is designed using the high quality of DUPLEX 31803 alloy. Also, we keep in mind several production norms and industrial standards (API, ASME, and ASTM). The types other seamless in which the pipe of the same grade is made available are welded, ERW, fabricated, EFW, Saw, rectangular, square, triangular, oval, and rectangular. The schedules are SCH 20, SCH 80, SCH 40, SCH 30, STD, SCH 160, SCH 140, SCH 120, etc. The lengths are single random and double random and in demanded sizes as well.
Duplex UNS 31803 materials are one of the most commonly used duplex steel grades available in the market and are used for making products like pipes etc. This material is having excellent resistance to stress corrosion cracking and general corrosion. Also, it has outstanding mechanical strength. However, this material is intended to use at temperatures ranging more than 300 degree C because of embrittlement.
Because of many good features, the demand for Duplex Steel S31803 Tubes and Pipes has significantly got maximized. The features of these pipes are outstanding corrosion resistance, high tensile strength, ideal for use in high-temperature applications, rugged constructions, high yielding strength, crevice corrosion resistance, IGC resistance, etc.
DUPLEX 31803 SEAMLESS PIPES applications include chemical processing, oil & gas industries, pulp & paper industries, liquor tanks, etc. The thorough quality testing is done of the whole range of DUPLEX 31803 SEAMLESS PIPES. Thus, it assists the supplying the superior quality of pipes only. Few tests are hydrostatic test, PMI tests, chemical tests, eddy current tests, etc.
