GOST / ГОСТ 12821-80 Flanges

India’s Leading ASTM A350 LF2 GOST / ГОСТ 12821-80 Lapped Joint Flanges, GOST / ГОСТ 12821-80 SOFF, GOST / ГОСТ 12821-80 Blind Flanges, Monel GOST 12821-80 Flanges, SS GOST / ГОСТ 12821-80 Flanges, Inconel ГОСТ 33259:2015 12821-80 Flange Manufacturer & Supplier in India.

Kanak Steel & Engg Co. is a known exporting and supplying unit of GOST / ГОСТ 33259:2015 / 12821-80 Flanges, which are used for numerous purposes, along with furnishing.

It combines excessive mechanical electricity and exact ductility with wonderful corrosion resistance in numerous environments. Typical packages of flanges encompass many additives for the chemical processing, marine, oil and fueloline, pollutants manipulate and meals industries among others. They are commonly extra significantly alloyed material, extra complex, and provide even advanced oxidation resistance and strength, for making them suitable for extraordinarily tough packages. Low carbon content material of flanges significantly lowers the danger of carbide precipitation on the grain obstacles for the duration of warmness treatment.

Therefore, the alloy is extraordinarily proof against carbide-associated intergranular corrosion. Typical makes use of Flanges are for Underwater manifolds, Flow lines, Process piping and pipelines, Underwater pipelines, Topside manner systems, Well heads, Pump pipes and riser pipes. They are designed to provide an extremely good mixture of warmth resistance, excessive temperature corrosion resistance, longevity and electricity, and are used within the world’s maximum technically worrying industries. It possesses exact weldability and may be joined to itself or different substances through shielded metallic arc welding, fuelling tungsten arc welding, plasma arc welding, flux cored wire, or submerged arc welding.

They are used for exceptional packages including in Aircraft exhaust manifolds, Expansion joints, Furnace elements, Heat exchangers and so on. Preheating of flanges isn’t important besides to save you condensation on a stony metallic. They are hardened on numerous parameters including electricity, temperature, strain resistance and sturdiness earlier than furnished to the customers. In dilute sulphuric acid infected with chloride ions, it has higher corrosion resistance, that’s an extraordinarily alloyed austenitic metallic grade in particular designed to face up to natural sulphuric acid. It is one of the maximum often used styles of metallic and is used to fabricate merchandise and elements for an in depth variety of packages. As a result, they may be getting used for sizeable programs in numerous markets inclusive of Petrochemicals, Refineries, Thermal, Oil & Gas.
