Description

Heat treatment unit RT150-12 is the best one for work in workshops at pre-assembly of tube assemblies. 

This unit allows multi-zone process control of heat treatment in different modes for preheating before and during welding or post-welded heat treatment of any welded joints. 

Same units found its application in air cooled heat exchangers manufacturing, pipelines of power stations (atomic hydroelectric etc.)

Post-welded heat treatment unit RT150-12

it easily ensures heating of welded joints in different joints while using this unit. Separate channel controllers can be started any time and execute different heating programs for welded joints at same time. 4 heating elements, connected to heating channels, allows to heat welded joints of pipe 325 mm OD up to 650 Celsius degrees.
