SMO 254 Pipes

Forms and Shapes of Pipes

Seamless Pipes:- – Unlike normal pipes, Seamless Pipes are without seam and weld, hence can withstand high pressure, high amount of mechanical stress. It’s an ideal choice to carry high-pressure liquid and gas. We also have them in different shapes like – Square Seamless Pipes, Rectangular Seamless Pipes, and Round Seamless Pipes.

Welded Pipes:- Due to the weld seam which it possesses Welded Pipe exhibits lower operating pressure, as compared to Seamless Pipes. But on the other hand, they possess tighter dimension tolerance then seamless pipes. We also have them in different shapes like – Square Welded Pipes, Rectangular Welded Pipes, and Round Welded Pipes

ERW Pipes (Electric Resistance Pipes):-They are made from HR strip/coil by rolling down the metal and welding them longitudinally along the length, so as to achieve higher diameter. We also have them in different shapes like – Square ERW Pipes, Rectangular ERW Pipes, and Round ERW Pipes.

EFW Pipes (External High-Frequency Welded Pipes) or HFW pipes (High-Frequency Welded Pipes):- In HFW pipes, high-Frequency current is used to make weld to circularly rolled sheets. And in EFW pipes, External High Energy electric arc is used to create weld to circularly rolled sheets.
We also have them in different shapes like – Square EFW Pipes, Rectangular EFW Pipes, and Round EFW Pipes, Square HFW Pipes, Rectangular HFW Pipes, and Round HFW Pipes.

SAW Pipes (Submerged Arc Welding Pipes):-  In this method of making Single seam SAW pipes, the welding arc is submerged in welding flux and the rolled sheets or coils are welded first from inside and then from outside.
In Double Seam SAW pipes, two half are joined using tack-weld also know as fit-up. After two-welded-seam opposite of each other are used simultaneously both from inside as well as outside. This method is used for high thickness pipes or multiple pass welding pipes.
In Spiral Welded SAW pipes, a steel sheet is rolled in form of circular loops which are then welded both from inside and outside. Spiral Weld pipes are usually applicable in low-pressure applications and hence cheaper than straight SAW pipes. This method helps in manufacturing welded pipes of varied sizes.

We also have them in different shapes like – Square SAW Pipes, Rectangular SAW Pipes, and Round SAW Pipes.

Duplex UNS S31803 / UNS S32205 Pipes Suppliers

Duplex 2205 Pipes | ASTM A790 UNS S31803 Pipes | WNR 1.4462 UNS S32205 Pipes | Duplex UNS S32205 Pipes Suppliers

Duplex 2205 alloy is equally ferritic and austenitic in nature, and hence a widely used grade of Stainless Steel. It consists of 22% Cr and 3% Mo, 5 to 6% Ni alloyed stainless steel.

In addition to high strength and excellent impact toughness, stress corrosion cracking resistance and high strength is exhibited by its Ferritic nature whereas ease of fabrication and corrosion resistance are exhibited by its Austenitic nature. It has high applicability where demand for good corrosion resistance and good strength is required. In oxidizing, acidic and caustic environments, it exhibits good resistance towards pitting and crevice corrosion.

UNS S32205 Pipes are applicable in chemical processing, pulp and paper production, marine and other high chloride environments, Liquor tanks and paper machines, Transport and storage, Oil and gas exploration and processing equipment. Oshwin Overseas has a huge inventory of Duplex UNS S32205 Pipes in different standards and different dimensions, thickness, and sizes.

SMO UNS S31254 Pipes Suppliers

SMO 254 Pipes| ASTM A312 UNS S31254 Pipes | WNR 1.4547 UNS S31254 Pipes | UNS S31254 Pipes Suppliers

SMO 254 Pipes is a super austenitic stainless steel alloy, with very high-end molybdenum and nitrogen content with low carbon content. Since it has Low carbon, hence less chance of carbide precipitation during heating. It exhibits good resistance to pitting and crevice corrosion, very high resistance to chloride stress, corrosion cracking, Excellent impact toughness, and high ductility, Excellent workability and weldability.

It possesses a lower coefficient of thermal expansion and higher thermal conductivity. Also provides good general corrosion resistance and sulfide stress corrosion resistance. It is 50% stronger than 300-series austenitic stainless steels and has a Pitting Resistance Equivalent (PREN) of > 42.5.
