Copper Pipe for Medical Gas Pipeline System (MGPS)

Medical Grade Copper Pipes

At Metal Alloys Corporation we proudly manufacture marked Medical Grade Copper Pipes used in Medical Gas Distribution system. Uninterrupted Medical Gas supply is a necessity in hospitals (ICCU, Operation Theater, Wards, Nursery etc). Pipes facilitate this in most effective manner.

marked medical grade copper tubes are manufactured as per EN13348 / BS EN 1057 specifications. The pipes are manufactured under thorough inspections and quality control measures.

marked medical grade copper tubes are available in size range 6mm to 108mm OD, 0.6mm to 2.0mm wall thickness in Half Hard/Hard conditions and Length 3 meter as per requirement.

Pipes are subjected to Third Party Inspection agencies like Lloyds, SGS, TUV as per customer demand.

  • Grain structure is compact and unidirectional
  • Grain size is less then 0.025µ mm

  • Alpha & Beta phase non uniformly distributed
  • Scattered Grain structure
  • Grain size
Manufacturing Process Seamless Extrusion of Hollows
  • Higher compactness
  • Better hardness
  • Surface roughness (RA) of finished product can be easily achieved with minimum turning loss.
Sand / Gravity Casting Methods
  • Low compactness
  • Higher porosity
  • Higher machining cost
Machining Better machinability as brass alloy with minimum Process loss. Due to alloy composition higher machining Required for achieving desired component.
