Lifting and handling of a Pressure vessel

Pressure Vessel Heads Ellipsoidal Head, Hemispherical Head and Torispherical Head are three types of ASME Pressure Vessel Dished Heads. Ellipsoidal head This is also called a 2:1 elliptical head. The shape of this head is more economical, because the height of the head is just a quarter of the diameter. Its radius varies between the major and minor axis. Hemispherical head A sphere is the ideal shape for a head, because the pressure in the vessel is divided equally across the surface of the head. The radius (R) of the head equals the radius of the cylindrical part of the vessel. Torispherical head These heads have a dish with a fixed radius (CR), the size of which depends on the type of torispherical head. The transition between the cylinder and the dish is called the knuckle. The knuckle has a toroidal shape.

Cylindrical Pressure Vessel

Cylinders are widely used for storage due to their being less expensive to produce than spheres. However, cylinders are not as strong as spheres due to the weak point at each end. This weakness is reduced by hemispherical or rounded ends being fitted. If the whole cylinder is manufactured from thicker material than a comparable spherical vessel of similar capacity, storage pressure can be similar to that of a sphere.

Product Description

Our Pressure Vessel Designing services are specifically intended for catering to the requirements of refineries, chemical plants, power plants, nuclear plants and other processing facilities. Besides designing, we also support for continued operation in leaked vessels or vessels that do not meet the standards of minimum required thicknesses based on structural considerations. Our assistance is also rendered to clients in case of accidental over-pressurization, where we evaluate the pressure vessels for avoiding any accident in the future. We design the pressure vessels in such a way that it achieves maximum efficiency and use. Our team of technicians and engineers is capable of rendering complete solution for custom design process, starting from creating an initial design in Auto CAD till subjecting the completed vessel through testing for ensuring that it will stand the test of time.
