Medical Grade Copper Pipeline With Tubing’s, Fittings, Pressure Gauges . The copper pipes shall be copper annealed ASTM B/75/B68 or equivalent standards.The Diameter of the pipe should be suitable for 1000 LPM average flow and this pipeline will have to be divided into two in the oxygen supply plant and attached to two pipelines systems presently feeding the hospital.Grossly the diameter should not be less than38mm X 1.5mm or thicker so as to bear pressure of 10 -12 All pipe work materials shall be manufactured by BS EN ISO 9001:2000 registered companies marking for sizes up to 108 mm, copper pipes shall be permanently and durably marked at regular intervals along its length with the following information -The harmonized standard number EN 13348; -Lloyds/BSI Kite mark or equivalent approved to EN 13348:2008 -Nominal dimensions, diameter x wall thickness; -Temper designation to EN 1173; -Manufacturer's identification; -Date of production: year and month (1 to 12) -Confirmation of degreasing for oxygen Brazing shall be carried out flame source temperatures and materials as per HTM/ NFPA recommendations Brazed Pipeline Joints (Copper to copper) should be made using a silver-copper-phosphorous brazing alloy CP104 (5% Silver Brazing Filler Metals Rod) to BS EN 1044-1999, no flux to be used. Copper Fittings: Medical Gas Pipeline Fittings shall be end feed type, manufactured from the same grade of copper as the pipes and be in accordance with the requirements of BS EN 1254- 1:1998 Part 1. O.D 28mmX0.9 mm thick

The manufacturing company should comply with BS EN ISO 9001:2000 and should be Kite Marked/Lloyds or equivalent to EN 1254-1 (up to 54mm). Fittings should be factory degreased suitable for oxygen use and be supplied individually sealed in protective polythene bags. Fittings should be certified for medical use and accompany with oil analysis certificate and Conformity certificate indicating suitability for medical use. Protection for pipes The pipelines in the bare area like space between buildings should be suitably protected and covered with fire resistant/ retardant insulation in such a manner that inner copper pipe does not come in contact with outer GI pipe. High Quality GI pipe quality covers which should be welded in such a way that only authorized person can open it using proper tools only. Further these should be of such a material and supported in such a manner so as to take load of monkeys/ languor’s. Any such supports required should be quoted in the technical bid in the civil work. Uncovered Sections of GI pipe will have to be protected with weather resistant stainless steel Barbed wire. The pipeline should be suitable for tolerating temperatures of (–) 10oC to (+) 30oC and high ambient humidity exceeding 90% and ice formation during winters. Given the length of the all end connections, pressure gauges, valves and fittings of cascade shall be within tamper proof, See through and wire cage enclosure. These shall Parts of the pipe between the building blocks may have to be supported with columns/ beams of iron angle or concrete if necessary, which will have to be done by the firm laying down The copper tube used for venting (if any) shall be of ASTM B75, B68.The rate is including octroi, royality, Malkana, toll tax, and any other taxes imposed by the Government but excluding GST. Sizes of pipeline with above specification to be used. O.D. 22mm x 0.9mm thick

Shut Off Valve with Brass fitting. The rate is including octroi, royality, Malkana, toll tax, and any other taxes imposed by the Government but excluding GST. 28 mm
