Technical Data

GS-Hydro has developed a number of machines, designed for cold flaring of tubes and pipes from 6 to 608 mm in diameter.

The machines are suitable for the flaring of a wide range of materials including carbon and stainless steel, duplex, copper, copper-nickel, etc. All the machines use a “rolling cone” method to achieve a perfect surface finish, which is suitable for JIC-37o and GS-37o and GS-90o Flare Flange Systems.

GS-Flaring Machines are available from light, portable machines to heavy-duty factory-type machines for the flaring of the following tube and pipe sizes:’
