Stainless Steel 321H Welded Pipe / Tubes composition having low nickel and molybdenum and exhibiting high corrosion resistance and good formability. Stainless Steel 321H Welded Pipe / Tubes are often chosen because of their resistance to corrosion, they are not immune to it. Stainless Steel 321H Pipes & Stainless Steel 321H Tubes are mostly used in space heating, oil and gas equipments, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, water and oil and gas transmission, petroleum refineries, natural-gas processing, sea water applications, and sewage treatment. Stainless Steel 321H Welded Pipe / Tubes are preferred for transmission since they can withstand harsh climatic conditions and high internal and external pressure.

Stainless Steel 321H Welded Pipe / Tubes Specifications

Generally Stainless Steel 321H Welded Pipe / Tubes are less expensive, have narrower tolerances, thinner nominal wall thickness, better concentricity (outer/inner diameter OD/ID), higher internal surface quality and are often chosen since they can be produced in longer lengths with larger diameters. Initially all stainless steel tubular products were of seamless construction, but with improved metallurgy and welding processes, the benefits of welded products have diminished the use of seamless.

AOD melting technology and precision cold-rolling/slitting processes combined with rapid technological leaps in welding techniques resulted in Stainless Steel 321H Welded Pipe / Tubes supplies soon becoming the dominant market supply. Longitudinally welded stainless steel 321H tubes for pressure applications are fusion welded with inert gas protection with or without filler metal. The corrosion resistance of the weld is of the same level as the base metal and the strength higher than the base metal.

Depending on the outer dimension, wall thickness and final application of Stainless Steel 321H Welded Pipe / Tubes, there are different ways of manufacturing SS 321H welded tubes and pipes. SS 321H Strip welded tubes are typically made in accordance with the production route. The material is decoiled, preferably into a strip accumulator which then enables continuous tube production.

Processing and testing advancements on the SS 321H welded and cold worked tubing have created many technical and commercial advantages over the seamless product. Their high strength makes them ideally suitable for pressure applications within the oil & gas, petrochemical, chemical, energy, pulp & paper industries, etc

Stainless Steel 321H Pipe & Tube Value Added Options

Stainless Steel 321H Pipe Polishing

Ashtapad can polish nearly any stainless steel pipe item to a #4 polish, #6 Polish, #7 polish or a #8 mirror finish. Stainless steel polished pipes can also be cut to size.

Stainless Steel 321H Pipe Beveling

Ashtapad can bevel stainless steel pipe to prepare for welding or other processes.

Stainless Steel 321H Pipe Honing/Turning

Ashtapad can hone pipe and tube, using a precision abrasion process in order to obtain a desired finish or close dimensional tolerance.

Heatreating & Annealing

Some grades of stainless steel pipe and tube can be heatreated to change the mechanical properties. Precipitation Hardening Stainless Steels such as 17-4PH can be heatreated. 410 stainless steel plate can also be heatreated. In some cases, secondary annealing 300 series stainless steel may be required depending on the application

Positive Material Identification (PMI)

Ashtapad can perform PMI testing in house for most stainless steel grades, or we can work with independent labs to complete PMI in order to meet customer specifications.

SS 321H Pipe/ Tube UT Testing

In some cases, UT testing of the stainless steel pipe and tueb may be required. We can assist you with this requirement.
