Nickel Alloys Seamless Pipes and Tubes

Nickel Alloys Seamless Pipes & Tubes

Petroinox Private Limited has a facility specialised to the production of Nickel Alloy Seamless Tubes.

The plant has a Water Hydraulic Hot Extrusion Press with a capacity of 1750 MT. The company's fundamental competency is their Hot Extrusion Press, which allows it to make Mother Hollows with tighter dimensional tolerances and a better surface polish. Ratnamani is self-sufficient in the production of Mother Pipes containing a unique chemical.

Nickel Alloy Seamless Heat Exchanger Tubes are manufactured using Hot Extruded Mother Hollows. High-speed Cold Pilger Mills and contemporary Draw Benches are used to make the tubes. Off-Line Bright Annealing / Conventional Annealing furnaces are used to heat treat the tubes.

Petroinox Private Limited can provide tubes with reduced residual stress values, which is critical for the service life of high-pressure heat exchanger tubes.

Petroinox Private Limited has a dedicated facility for producing U bend Solution Annealed Tubes up to 40 metres in developed length.
