Medical gas outlet pipes supply, install, commissioning and testing of copper pipes drawn half hard temp.,solid drawn, seamless, Phosphorous di-oxidized, non-arsenic and degreased copper pipe (Grade CW024A/Cu-DHP) conforming to EN13348:2001with incorporation of amendment. All pipes should be installed as per HTM 2022 or NFPA 99. The supplies of copper pipe would be accompanied with manufacturers test certificate for the physical properties of copper pipes and their Chemical composition. The supply of pipes be further substantiated with inspection certificate from the third party like SGS/ Lloyds Register (MAKE: RAJKO, JANYA, MAX FLOW). Fittings:All copper fittings shall be manufactured to the highest standards complying with EN1254-1. The fittings should be manufactured in accordance with EN1254-1 and 4 (formerly BS864:Part 2). Copper pipes would be secured to wall with LDPE saddles or to ceiling fixed MS bracket wherever necessary . Brazing :For copper joints, brazing material to be used will be silver-copper phosphorous alloy which shall be used without flux. For copper to brass joints 43% silver brazing rods with flux would be used.Flow of nitrogen gas would be provided to avoid oxidization inside the pipeline during brazing. Fabrication: Cleaning : Before putting for erection all pipes,valves and fittings shall be cleaned and degreased.Pipe and tube joints: For copper fittings in the copper pipeline,the brazing for copper joints shall be done without using flux and the material for jointing used will be silver-copper phosphorous alloy. For brass joints for jointing outlet points and area/zonal valves material used is 43% silver brazing rod with specified flux. For installation of equipment's threaded connections equipped with nut, nipple & adaptors are used.

Bends: All bends are made of copper pipe of higher Dia than the pipe requiring change of direction and these bends will be made out of thicker size pipe to avoid thinning and flattening at any point.Erection:The erection of the copper pipe shall be done only after cutting the pipes to size as per site requirements.It does not leave any scope for springing. Supports:To avoid weight of the pipe on the joints supports (saddles made of LDPE material) are provided at a distance of every 4-6 feet as prescribed by HTM-2022 and NFPA99. Testing Blowing:After erection all the pipes are blown with nitrogen or compressed air. This blowing of the pipeline with nitrogen or compressed air under pressure cleans the pipeline thoroughly Joints tests: The entire pipeline after erection is put to test for checking leakage of brazing joints at a pressure one and a half times of the working pressure for 24hours. In case of drop in pressure the joints are examined with soap solution. Final test: After repairing the joints in case leakages are found, the pipeline shall again be put to test with compressed air at a pressure of one and a half times the working pressure for 24hours and then there after entire pipeline will be tested with specific gas for anti-confusion tests.Painting: All pipes after lying shall be painted as per color specification "IS CODE "2379: 1963 amended 1990 or BS1710: 1984 for size of 15 x 0.9mm outer dia complete all as specified and directed.
