Stainless Steel Tube Fittings Manufacturer in India
Kalpataru Piping Solution is a reputable and established producer and distributor of high-quality stainless steel tube fittings in India, which produces precisely engineered products to serve global industries. We develop our stainless steel fittings based on well-regulated chemical compositions that increase their durability, resistance to corrosion, and overall performance in harsh environments. In our SS Tube Fittings, chromium is the main alloying element so that the strong passivated oxide covering offers long-term reliability since the surface is not susceptible to oxidation and rusting.
As a way of satisfying the various needs of industries, we produce stainless steel compression fittings, push-in fittings, pneumatic fittings, tube nuts, and sleeves to meet the different grades. Our fittings can be alloyed with molybdenum and are able to resist reducing acids and other harsh chemicals as well, and thus are suitable for chemical processing, manufacturing of fertilizers, and sea use. Such grades are also extremely effective in the presence of phosphoric and nitric acids at room temperatures.
Wherever possible, we absorb nitrogen in some of our stainless steel 304 tube fittings grades in environments likely to be exposed to pitting or chloride attack. This addition also contributes greatly to pitting resistance and strength, and so our fittings are suitable for high-pressure and high-temperature utilization.
At Kalpataru Piping Solution, we have integrated high-level production, rigorous quality testing, and international standards to provide reliable, high-performance tube fittings in stainless steel that can be used in all types of industries.
