First of all, it should be considered that transport and erection operations of pressure vessels could be focused from two different points of view, which are intrinsically related. On the one hand, the pressure vessel must not be damaged under no circumstances, since the moment the equipment leaves the manufacturer’s workshop until it is installed […]

Conical transitions are really usual in several industrial sectors so that people minimally related to design or manufacturing of pressure vessels are used to deal with them. The shape or these conical sections is mainly imposed by the process in which vessel is immersed. In order to satisfy properly the process needs, the conical part […]

Thin-walled pressure vessels are widely used in industry for storage and transportation of liquids and gases when configured as tanks. For most applications, pressure vessels are either spherical or cylindrical. Depending on the application, pressure vessels will adopt one shape or the other. Most pressure vessels are fabricated from curved metal sheets that are joined […]

The word “cryogenics” comes from two Greek words, “kryos” meaning icy cold, and “genes” meaning to form. The term cryogenics was first used in 1875 and has come into general usage since 1955. Cryogenic temperatures are normally considered as below (-)100ºC. One of the major benefits of handling gases in liquefied form is the enormous […]

Non-standard flanges will only be used in cases where pressure, temperature and size requirements exceed the capabilities of standard flanges. Keep in mind that non-standard flanges require calculation, design and special manufacturing procedures, which is why they are chosen only as a last resort. The most common such applications are large equipment flanges and heat […]

Fatigue analysis is often more demanded for Pressure Vessels and Shell and Tube Heat Exchangers (S&T). Operating conditions involving pressure and/or temperature cycles could result in a fatigue analysis requirement. Previous to perform a fatigue analysis is necessary to run screening criteria in order to check according to ASME VIII Div. 2 Ap. 5.5. if […]
