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 designer, these codes impose certain safety factors in the calculation of allowable ...
ensuring that pipes can safely withstand the internal pressure and other loads they may encounter during operation. A pipe is considered to be a thin-walled vessel and the wall thickness of such elements is calculated using Barlow’s formula. The pipe wall thickness is proportional to the interna...
THIN-WALLED LINER FOR HIGH-PRESSURE VESSELS This invention involves thin-walled liner of amorphous materials for high-pressure vessels of composite material, e.g. fiberglass, containing a central cylinder part and two faces, with a socket in one of them. The thickness of face and ... KS Gle...
When the pressure vessel is designed without checking hole, thecalculated thicknessof the pressure vessel written on the drawing, sometimes, is not the same illustrated in GB150-89. 在压力容器中不设置检查孔所需标注的“计算厚度”,并非是GB150-89中的“计算厚度”,应考虑参与补强所需厚度这个因素。
Vessels working with static loads, made of ductile metals for which small elasticoplastic deformations are permissible in narrow stress-concentration zones, are most economically calculated for strength using the method of limiting loads. The wall thickness of the vessel, calculated using the limiting-...
Under the assumption that wall thickness of a polyhedron keeps constant during bulging, the constant-area spheritaxis principle is put forward. With this principle, methods of calculating diameter, wall thickness of a polyhedron and pressure under which the polyhedron becomes a spherical vessel are ...
These factors, together with the migration of smooth muscle cells and the formation of cholesterol crystals, increase the arterial wall thickness which reduces the luminal area where the blood flow takes place. A detailed description of the evolution, composition, and classification of atherosclerotic ...
