Kalpataru Piping Solution is a leading manufacturer and exporter of high-quality Super Duplex S32750 Tube to Female Pipes, which can only be hardened by cold working and cannot be toughened by heat treatment. Parts constructed from Super Super Duplex S32750 Tube Fittings tend to find good use across a wide range of chemical applications that might otherwise oxidise the metal, in addition to outstanding resistance to all kinds of pitting and cracking. Non-oxidizing acids such as hydrochloric acid and sulphuric acid have no effect on Super Super Duplex S32760 Tube Fittings.
Superior thermal stability and manufacturing qualities distinguish Super Super Duplex S32750 Female Connector Fittings from earlier B-family alloys. Super UNS S32760 Female Connector Fittings, which were newly created, can withstand stronger non-oxidizing acids than C-type alloys and can endure oxidising impurities that B-type alloys cannot. It has been extensively used to protect against the most corrosive FGD systems and the most sophisticated pharmaceutical reaction vessels. UNS S32750 Compression Fittings is particularly resistant to pitting and crevice corrosion.
In the fertiliser business, Super Super Duplex S32760 Compression Fittings have been particularly effective as phosphoric acid heat exchanger tubing and other process components. Super Super Duplex S32750 Ferrule Fittings have a high chromium content, making them ideal for use in oxidising solutions and mixed acid pickling. Standard shop fabrication procedures can easily weld and process UNS S32760 Double Ferrule Fittings.
