Petroinox India is an ISO 9001: 2015 certified company has engineered a wide range of products that are quality assured and guarantee complete customer satisfaction. We, at Petroinox India, focus on the fit and finish on every product of ours. Our clients are our priority, and we work to provide complete satisfaction to them.
We are a manufacturer, trader, stockist, supplier and exporter of Stainless Steel 321 Pipe Fittings, which are a member of the austenitic group of fittings, with a slight change of being stabilized by adding Titanium, which is, a hero, saving the fittings from falling prey to Carbide Precipitation due to Chromium. Thus, these stabilized fittings are available in seamless as well as welded nature, in some finishing and end connections.
We are a leading producer of SS 321 Buttweld Fittings that have excellent intergranular and general corrosion resistance, thus capable of joining pipe conveying moderately corrosive solvents and organic media. Additionally, our couplings are design-adaptable and provide snug fit installation and low maintenance service life.
Our products are completely certified, quality tested and offer complete satisfaction.
