Why does IPP call its convoluted pipe flanges IPP DELTAFLEX ?
The IPP DELTAFLEX Pipe Flanges are patented. They offer further performance improvements over the old patent-expired version. Since IPP maintains a full time engineering staff as well as a full time stress analyst, it contributes through this exceptional effort to the piping industry product performance assurances in terms of pressure/temperature ratings, safety factors, etc. In order to assure you get the real thing, specify IPP DELTALFEX flanges or back-up rings and reject anyone who claims savings but cant support its engineering. Obviously, copying is much cheaper but from where does one know whether the copy is a patent protected one? Savings and safety demand documentary evidence. IPP DELTAFLEX flanges provide that.
