With the exception of the basic raw material of steel coils/strips, valve necks and gas flow control valves, which are sourced externally, the whole process is carried out in our factory, in the second industrial city in Riyadh The Cylinder production is carried out in three separate divisions In the first stage, the metal fabrication takes place.
The collars, base rings, mid sections and top & bottom shells are produced from steel coils/slits. The various processes include blanking, shearing, deep drawing, piercing, trimming & beading, embossing, rolling and forming. The formed parts are then conveyed into the welding division. Here, all parts thoroughly degreased to ensure total welding integrity In this division, the welding process of valve necks and collars to the top shells, base rings to the bottom shells and the long seam on the mid sections take place.
The top and bottom shells and the middle parts are assembled and circumferential seam welding take place resulting in semi-finished cylinders. All welding is done automatically The final stage of production takes place in the finishing division.
