Manufacturing Line:


Step 1:  Inspection Of Raw Materials
The steel coils are straightened and circular blank sheets are cut via the hydraulic press.

Step 2:  Hydrolic deep drawing press & Edge Trimming
The deep drawing hydraulic press transforms the sheets into half elliptic forms. For each pair produced the edges will be cut, one will be trimmed and the other will be juggled joint formed.

Step 3:  Collar Welding
The valve boss (collar) is welded by electrical arching on the punched hole which is assigned to it on the middle top end of the shell.

Step 4:  Valve Guard & Footring Welding
The valve guard and foot ring are welded by electrical arching on the top and bottom end of the elliptic shells.

Step 5:  Circumferential Joints Welding
Fitted drawn halves are welded at the circumference via the automatic welding machine.

Step 6:  Pneumatic Pressure Test
The cylinder then undergoes the leakage test by dipping each into a tub of water and applying air pressure into the valve. Any leakage can directly be spotted by air bubbles that would be visible to the naked eye.

Step 7:  Heat Treatment
The chemical composition of the cylinder is unified allowing it to regain its original properties by entering the annealing furnace (oven). Cylinders are uniformly heated to reduce the residual stress without altering the structure of the steel.

Step 8:  Shot Blasting
In order to apply the primary coat onto the cylinders, the surface of each cylinder is shot blasted therefore creating a smooth metal surface.

Step 9:  Paint and Zinc Coating
The cylinders are then sprayed with zinc (which prevents it from rusting in the long run) and powder coated via the spraying booth's automated guns.

Step 10:  Valve fitting

The valve is fitted onto the top of the cylinder after having the threads in the cylinder opening cleaned (to remove any foreign material).

Step 11:  Hydraustatic Pressure Test
All cylinders are then pressure tested according to the required standard.
