ASME BTH-1 Standard – Design of Below the Hook. Lifting Devices, arises after the creation by ASME of a design task group in 1997, to develop a design standard that complements the ASME Code B30.20 Below the Hook. Lifting Devices. Safety Standard, for the design of lifting elements. The standard was published in 2005, consisting […]

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 […]

External pressure can be caused in pressure vessels by a variety of conditions and circumstances. The design pressure may be less than atmospheric due to condensing gas or steam. Often vessels are design for some amount of external pressure, to allow for steam cleaning and the effects of the condensing steam. Other vessels are in […]
