Description of DI universal coupling for all kinds of pipes                                                

Universal Flange adaptors facilitate the connection of plain ended pipe to flanged  products , in the same range

 of outside diameters, and multi-drilling flanges further simplify installation.To facilitate installation and avoid

 possible creep under rising load, it is strongly recommended that the rubber sealing gaskets are well lubricated

 with a suitable non-toxic soap solution before the introduction of the pipe. This practice should obviate the need

 for retightening the fasteners after pressure testing, and further facilitate the seating of the joint components.
