Carbon Steel Pipe Fittings Manufacturer

Carbon Steel Pipe Fittings Manufacturer

Metline Industries is a growing manufacturing company in the field of carbon steel flanges, carbon steel fittings and low temperature carbon steel fittings and flanges. Our rich technical experience and organized production procedures has helped us become one of the most trusted supplier of carbon steel fittings and flanges to large shipyards, fabrication companies, chemical plants, oil refineries, machinery manufacturers, textile, and fluid transportation companies among others.

In general, carbon steel pipe fittings and flanges are widely used for applications which do not require materials with higher resistance to corrosion such as stainless steel and nickel alloys. Carbon steel products corrode and get rusted easily if exposed to water.

METLINE offers a complete range of pipe fittings such as carbon steel reducer, carbon steel elbow, carbon steel tee, carbon steel cross, carbon steel stub ends and carbon steel pipe bends. Our carbon steel or mild steel forged flange products include threaded flange, weld neck flange, slip on flange, socket weld flange, blind flange, lap joint flange, plate flange. We specialise in the manufacture of special size and custom shape flanges for our customers.

We can manufacture and offer high quality carbon steel pipe bends with bending radius ranging from R=3D-10D and bending angle of 10 degree to 180 degree. In addition, we can also manufacture carbon steel bends as per custom requirements of our esteemed clients. All our carbon steel fitting and flange products are supplied with relevant test certificates of raw materials and finished products. Carbon steel pipe bends with a bending radius 3D, 5D and 7D are most commonly used across various industries. Our key pipe bend products include – high quality carbon steel long radius piggable bends, seamless long radius piggable bends and welded long radius piggable bends.

METLINE also stocks and supplies a complete range of carbon steel seamless and welded pipes to complement our existing production range of buttweld fittings and flanges. Carbon steel pipes can be supplied in cut to length sizes and also machined or fabricated to meet your piping requirements.
