The calculation of pressure vessel wall thickness is made with formulae usually imposed by national codes. Although the Lam茅s formulae give actual stresses and leave the decision on the safety factor to the des
Figure 2. Pressure vessel applications. 35 MPa) require materials of higher strength to keep their wall thicknesses at practical levels. It should be noted, however, that high-strength steels have limited use due to possible degradation of their mechanical integrity through hydrogen embrittlement. In...

This technology had been applied in welding of circular seams of several thick-wall pressure vessels. The test results of product could completely satisfy the requirements of code and design.关键词: low alloy steel thick-wall pressure vessel double-wire SAW narrow gap ...
The changes in PP and SBP are proportional to volumetric changes based on the arterial wall characteristics defined by compliance75, where the parameters for the equation changes per individual (see Supplementary Fig. 3). The blood pressure pulse wave velocity (PWV) is also related to the ...
The liner of a CNG pressure vessel is manufactured by a DDI (deep drawing and ironing) process for the cylinder part, which is a continuous process that includes a drawing process to reduce the diameter of the billet and a subsequent ironing process to reduce the thickness of the billet. A...
