Flanged and dished heads with Omega Laser Plate

Omega Thermo Products is one of the few suppliers that can also supply F&D heads with Laser Plates under ASME, CE-PED, and CRN. Many of the bottoms supplied by Omega are used in the chemical and pharmaceutical industry. Also F&D heads are used for process tanks, with a full vacuum or high pressure prevailing in the tank.

Design

Two flat sheets of stainless steel are welded together and after this process the flat head is sent out for forming. Generally the Laser Plate covers 80% of the heads surface to allow the head to be formed without forming on the laser welded portion. The forming is hydro formed or bump formed depending on the size. The heads are sent to the customer fully formed, trimmed and ready to be installed on the tank. Once the head is installed the jacketing will be inflated hydrostatically.

Advantages

Using a laser welded head is a cost savings over welding on pre-formed dimple. There is also flexibility in design for isolations of tank connections and openings.

Other tank bottoms

Beside Flanged and Dished heads we can also provide cones or reverse dished heads with Laser Plates.
