placed between sections of pipe, squeezed between the flanges. This ring has a raised groove on both sides mating with the indentations of the two pipes on either side. * an enclosing clamp with C-shape clamping sections that cover the outer circumference of the flanges, applying pressure to squeeze the two pipe sections together onto the sealing ring. The clamp also provides structural strength and rigidity to the pipe sections. The combined lip flange and gasket do not impede the flow of fluids through the piping. The clamping system may be permanent, using a hose clamp style screw and band, or it may be easily removable using a fold-over hinged clamp assembly. ISO 2852 is withdrawn as international standard since 31 July 2018.
