PROCUREMENT PIPING AND FLOW CONTROL

Cold Bending Method

We are favored to offer a wide range of quality products in the Cold Bending process as it is possible to be applied on pipes made of carbon steel, alloy steel, stainless steel, duplex, titanium, welded (SAW or ERW) or seamless, with diameters ranging from 2″ to 60″. The radius can exceed 5D and angle 180°. All these are achieved by maintaining negligible ovalization and minimal thickness reduction.
Materials for hot and cold bending

Carbon and alloy steel for moderate and elevated temperatures
High yield steel
Carbon and alloy steel for low temperature service
Stainless steel
Ferritic
Austenitic stainless steel
Nickel alloy
Titanium alloy
Aluminum alloy
