Kalpataru Piping Solutionss product has renown for extensive longevity and high stability to perform tasks in less favorable and stress condition with ever changing factors. Use of many complex designs and professional expertise has brought about this innovation in traditional products into modern ones that would fit any existing industrial assembly.
Forged threadings are very similar to coupling function wise but are constructed to be complex structured comprising of three parts that can be assembled together to form one union fitting. Union fittings consist of two parts: Nut for female end and male end. Described nut is tightened in center and holds female and male ends together using a threading engraved on both of them. In a way unions function like a flange by connecting two pipes that are connected to their ends of union fitting. Union fittings are also available as dielectric union with combination of electrically dissimilar metal that prevents occurrence of galvanic corrosion.
