Process

The SA516 Gr70 BQ plate is cut in our profile cutting CNC machine and rolled into a shell with semi-automatic rolling machine.

 

Then the edges are welded with automatic SAW (Submerged arc welding machine) to ensure radiography proof joints.

 

The tubesheet is also faced in-house in our workshop and holed, bored and grooved at our VMC (Vertical machining center) with highest precision, speed and accuracy.

 

The seamless tubes are expanded by a torque transmitter drive unit at tubesheet ends which ensures leak proof joint.

The complete assembly undergoes hydro-pneumatic and vacuum testing as standard.
