Alloy Steel P91 Pipes
We are a known manufacturer, exporter and trader of AS P91 Pipes, which is a utility steel resistant to wet abrasion and mild corrosion – weld stabilized. Alloy Steel P91 Seamless Pipes is a free machining grade, which is used in domestic and mild industrial environment, along with nuts and bolts, shafts, fittings. Alloy Steel P91 Welded Pipes is used in the region molten very narrow and that formed when laser welding solves then fracture, and this shows that the welding area remains weaker than the base metal. Alloy Steel P91 EFW Pipes do not suffer uniform corrosion, like carbon steel, when exposed to wet environments. Alloy Steel P91 ERW Pipes is used in a maximum of carbon in the weld deposit, where the electrode is used for welding type.
Alloy Steel P91 Round Pipes is also used in hose clamps, exhaust manifolds, stainless hardware, storage tanks, pressure vessels and piping. Alloy Steel P91 Square Pipes has a lower risk of weld decay due to addition of titanium, where with addition of niobium for desensitization during welding. Alloy Steel P91 Electropolish Pipes are typically used in: Chemical processing, transport and storage; Oil and gas exploration and offshore rigs; Oil and gas refining; etc. Alloy Steel P91 Hexagonal Pipes offers exceptional corrosion resistance and is recommended to use smaller gauge electrodes and avoid weaving for lesser heat input.
