Alloy 20 Fittings Manufacturers in India
The Alloy 20 Fittings are made up of different metals that include nickel-iron-chromium alloy, that help a structure to resist corrosion and aggressive chemicals. It’s a high-quality alloy that is manufactured with the specification of UNS N08020 and ASME SB366; these standards ensure that the alloy is properly made and can handle high-pressure in industrial applications. Many pharmaceutical and petrochemical industries use alloy fittings in their structure. Which make their structure more durable and increases their shelf life. Kalpataru Piping is the most reliable manufacturer and supplier of Alloy 20 Fittings, and also other alloy products that include round bars, pipe and tube, and flanges, etc. All of our product goes through high testing and quality checks to match the industry level and help engineers build their structures easily.
