The various techniques that have previously been proposed for reducing peak stresses in pressure vessel nozzles by making the nozzle hole elliptical rather than circular are summarised. It is then shown that for nozzles in thick-walled cylindrical pressure vessels the optimal hole shape is likely ...
A radial nozzle assembly for use in a pressure vessel to enable fluid flow through the vessel wall is provided. The radial nozzle assembly has a nozzle and a cup-shaped flange extending from one end of the nozzle. The nozzle has a bore disposed therethrough along its length to permit ...
This significantly enhances the efficiency of local stress analysis at pressure vessel nozzles. Furthermore, the publicly available plugin automates and standardizes the process of local stress analysis. This eliminates subjectivity in the analysis process, such as stress linearization. Lastly, users can...
应力应变测定结果和断裂试验证明SCT试样能够较好模拟压力容器接管等高应变梯度区的力学特征和断裂特征。 Mechanics characteristic and fracture behavior of pressure vessel nozzles can simulated and we can...
Ellipsoidal heads are commonly used as end closures for cylindrical pressure vessels in chemical and process industries. In the design of nozzles in pressure vessels, stress and flexibility of the nozzle-vessel structure are important factors to be considered. In this paper, a parametric study of ...
The wear plate is just an non-pressure part all around the vessel, welded to both vessel and nozzle for tangential flow which may contain particles. Lots of applications in the industry, not a big deal. Using integrally reinforced nozzle may be ok, however, you will face a challenge in ...
Stress analysis upon opening of pressure vessel is a very common problem,but stress category around opening still has some disputes.Some people think bending stress around opening should be regarded as primary stress,while others label is as secondary stress.In this paper,an refining vessel is take...

A theoretical elastic analysis of the stresses due to a moment applied to a pad reinforced nozzle in a spherical pressure vessel has been carried out. The results have been compared with experimental values obtained by applying an external moment of 49·78 kN/m (200 tons/in) to one nozzle,...
CONSTITUTION: A nozzle cutting apparatus of a pressure vessel comprises a housing(110), a cut pin(300) and an igniter(200). The housing surrounds the end-blocked nozzle of the pressure vessel. The cut pin is movably installed within the housing. The igniter is combined in the housing and...
