Pressure Vessels Classification,Application Design,Erection&Inspect

Pressure vessels have been widely used in many industries. Pressure vessels can be classified according to many considerations. Some of these considerations are shape, pressure and temperature. According to pressure vessels could classified into Internal Pressure Vessel and external pressure vessel. The main components of pressure vessels are shell head, nozzle and support. Material selection process for pressure vessels is very important in pressure vessels design. The selection of construction materials for Code pressure vessels has to be made from Code approved material specifications. It usually specifies the most economical materials of low first cost and/ or low future maintenance cost that will be satisfactory under operating conditions and will meet other requirements. The modes of failure for pressure vessels should be consider to avoid catastrophic failures which could cause looseness in components or cause dangerous injuries. The inspection also considered a vital step in pressure vessels manufacturing and service.
