Pipe Cladding Station

FITco is honored to provide model XHL-PCS cladding station which is designed for pipes and vessels for oil & gas, chemical, valve manufacturing, pressure vessels and other industries.

The equipment is mainly used for less than 12.5m tube inner wall anti-corrosion welding, welding pipe is driven by end hollow chuck rotation, welding torch by wire rope pull and guide equipment positioning and complete welding into the channel.

It is suitable for the cladding of hot-rolled steel pipes, seamless steel pipes, forging pipes’

inner diameter from 130mm to 850mm.

It is powered by EWM Germany TETRIX 452 DC pulse arc welding power supply and the TETRIX 200 Hot Wire thermal wire power supply.
