Specialist Manufacturers of 347 Welded/ERW/Large Diameter Stainless Steel Pipes in India – Largest Suppliers of Fabricated & Custom Size SS 347 Welded Pipes at Lowest Prices!

Metline is one of the biggest manufacturer and supplier of stainless steel 347 welded pipes in India, with daily sales of around 25-30 tons to customers across India and overseas. Our regular stock of products include SS 304/304L welded pipes, SS 316L welded pipes, SS 321/321H welded pipes, Duplex welded pipes, and SS 201 welded pipes in size range of 1/2″ NB to 24″. We also stock and manufacture stainless steel 347 welded pipes in OD size range from 1/4″ OD to 12″ OD in thickness upto 10mm.

Stainless steel electric resistance welded (ERW) pipe is manufactured by rolling metal and then welding it longitudinally across its length. SS ERW pipes are manufactured from Strip/Coils and can be manufactured upto 12” NB. For sizes from 6” NB to 36” NB, Metline can produce fabricated pipes, made from cut to size plates. The plates are first rolled and then 100% X-Ray welding is done. Since large diameter stainless steel 347 welded pipes cannot be made on a rolling mill, we produce such pipes by rolling cut to size plates and performing welding operations on them. All large diameter 347 welded stainless steel pipes, are produced as per ASTM A358 Class I to Class V specifications. Meanwhile, stainless steel 347 welded pipes in sizes from ½” to 12” (SCH 5, SCH 10, SCH 40) can be produced on rolling mill as per ASTM A312 specification.

Stainless steel 347 welded pipes are widely used in crude oil industry, chemical industry, petrochemical industry, construction industry, and food industry. In addition to SS 304 welded or fabricated pipes, we also manufacture and supply related fittings, bends, flanges and fasteners.

About 347 Stainless Steel

347 is similar to the 321 stainless steels in that it is often used as a stabilized alternative to Type 304. In the case of 347, however, the stabilizing agent is columbium. This metal intensifies 347’s already present ability to withstand intergranular corrosion for maximum capabilities. Additionally, the columbium allows for 347 to undergo repeated heating in temperatures up to 1650° F. As a result, the metal is commonly applied to high temperature equipment, such as gaskets and expansion joints, along with rocket engine and chemical manufacturing.

In addition to its heat resistance properties, 347 also enjoys better resistance against creep and stress rupture corrosions. This is another advantage of type 304, as 347’s characteristics may be better suited for environments where stabilization is a primary concern.

Type 347 is known for being workable under all common welding techniques, along with hot and cold working. However, when being heat treated the metal must be heated up in the range of 2100 to 2250°F. This is due to 347’s inability to work harden under heat treatment. Cold reduction is the only method that will utilize the alloy’s elevated properties.
