IS 13916 : 1994 Code of practice for installation of glass fibre reinforced plastic (GRP) piping system

1 Scope

1.1 This standard describes procedure of laying GRP pipingsystem installation and includes requirements for trenching,handling, jointing, compaction of back filling and postinstallation hydrostatic test.

1.1.1 This code does not cover installation that require specialattention, techniques and materials like:

a) Pipe through rigid walls,

b) Subaqueous piping, and

c) Plant or pumping station piping.

NOTES 1 Pipes, fittings and rubber gaskets to be used forinstallation of piping system as per this code shall conform to thefollowing standards:

a) The GRP pipes, jointing and fittings shall conform to IS12709 : 1993.

b) The Rubber gasket shall conform to IS 5382 : 1985.

2 Appropriate stiffness class of the GRP pipe (see IS 12709 :1994) shall be selected to withstand the overburden (dead load),live load and vacuum conditions, if any, considering siteconditions.
