0.9mm
0.9mm

1.1 Copper Fittings
Copper fittings shall be made of Copper and suitable at working pressure of 17 bar and especially made for brazed socket type connections. Copper fittings should meet and as per EN 1254 standards.
1.2 Installation & testing
Installation: Installation of piping shall be carried out with utmost cleanliness. Only pipes, fittings and valves which have been degreased and brought in polythene sealed bags should be used at site. Pipe fixing clamps should be of non ferrous or non-deteriorating plastic suitable for the diameter of the pipe. All pipe joints should be made using flux less brazing method. All joints should be made of copper to copper. Adequate supports should be provided while laying pipelines to ensure that the pipes do not sag. The spacing of supports should not exceed 1.5 meter for any size of pipe. Suitable sleeves should be provided wherever pipes cross through wall/slabs. All pipe clamps should be non-reactive to copper.
1.3 Test
After erection, all the new pipes cleaned or purged with the help of dry nitrogen gas and complete existing and new system should be tested with dry nitrogen at
1.5 times of working pressure for 48 hours.
1.4 Painting & Supporting
Painting: All existing and proposed exposed pipes should be painted with two coats of synthetic enamel paint & color codification as per IS:2379 of 1963 standards. All concealed pipes to have gas identification bands/labels at appropriate distance.
1.5 Support
Supports should be provided to ensure that the pipes do not sag. The spacing supports should not exceed. 1.5m for size of pipe. Suitable sleeves should be provided wherever pipe cross through walls/slabs. All pipe clamps should be nonreactive to copper.
2.0 Gas Terminal Unit
The medical gas terminal unit: The wall mounted first fix assembly should consist of brass pipeline termination block with copper stub pipe permanently secured between a back plate and a gas specific plate which allows limited radial movement of the copper stub to align with the pipeline.
Terminal units should be gas specific and only accept the correct medical gas probe. Gas specific components should be pin-indexed to ensure that a correct gas specific assembly is achieved so that in normal course of dismantling for repair or maintenance, parts from other gases cannot inadvertently be used. Wall mounted terminal units should incorporate an anti-rotation pin to engage with connected downstream medical equipment ensuring correct orientation. Terminal units installed in booms or pendants should be attached to their respective flexible gas hose by a gas specific NIST fitting. Terminal units located in a rigid installation should be capable of single-handed insertion and removal of the correct medical gas probe.
