Pratik Pipe & Fittings is a renowned maker, supplier, stockist, and exporter of Stainless Steel 321 Flanges that offers an extensive range of superior quality products to meet the various industrial demands. The 321 austenitic stainless steel is stabilized through the use of titanium to produce an exceptional product that can be employed where there are corrosive atmospheres and exposure to elevated temperatures. The titanium added to the product minimizes the formation of carbides during the welding process to enhance the product's resistance to intergranular corrosion and ensure superior reliability and durability.
We offer our Stainless Steel 321 Flanges to withstand harsh environments with superior scaling and oxidation resistance to 900°C. The flanges are highly used within the chemical processing industry, petrochemical industry, oil and gas sector, and the power plant sector due to their superior mechanical properties and the ability to be stress corrosion cracking-resistant. We manufacture the flanges in forms such as Slip-On Flanges, Weld Neck Flanges, Blind Flanges, Socket Weld Flanges, and Lap Joint Flanges to meet the diverse needs of our customers.
Being the reliable manufacturers, suppliers, stockists, and exporters of Stainless Steel 321 Flanges, we maintain strict quality control measures and utilize top-notch quality raw materials procured from genuine vendors. We test our flanges through thorough quality control measures like material tests, dimensional tests, and pressure tests to ensure that our flanges are compliant to international standards like ASTM, ASME, ANSI, and DIN. We deal in various sizes, pressure classes, and specifications of these flanges to suit the various piping system and industrial uses.
Our commitment to quality, prompt shipment, and fair prices has made us the first choice amongst global customers. As premium exporters, we ensure that our Stainless Steel 321 Flanges are carefully packed to ensure that there is no damage during shipment, delivering them to our customers in the best possible condition.
