Kalpataru has been involved in overall production manufacture an deployment of clients and professionals requiring various industrial grade components as needed by the assembly. Use of many of these components has led to seamless functioning and flow of the industrial commerce.
Spectacle flanges are similar to core construction of various ordinary flange except for addition of a steel plate called P blind which has a momentary anti-clockwise motion that is beneficial in case of many piping system where supply must be stopped or allowed at recurring time instead of turning off the entire assembly completely. Spectacle blind flanges look like a pair of spectacle with one circular flange opening that is bigger then Steel Blind that acts as a blocker and blocks flow inside a pipe. Two flanges that are attached together can avail one spectacle blind to block either of them at one time.
