Tàu thuyền, xe tăng, và đường ống dẫn mang, cửa hàng, hoặc nhận được các chất lỏng được gọi là áp lực mạch. Một tàu áp lực được định nghĩa như là một container với một áp lực sự khác biệt giữa bên trong và bên ngoài. | Pressure Vessels Design Olid Practice Somnath Chattopadhyay cpp. CRC PRESS chapter one Overview of pressure vessels Contents Introduction. Development of pressure vessel construction codes. References. Introduction Vessels tanks and pipelines that carry store or receive fluids are called pressure vessels. A pressure vessel is defined as a container with a pressure differential between inside and outside. The inside pressure is usually higher than the outside except for some isolated situations. The fluid inside the vessel may undergo a change in state as in the case of steam boilers or may combine with other reagents as in the case of a chemical reactor. Pressure vessels often have a combination of high pressures together with high temperatures and in some cases flammable fluids or highly radioactive materials. Because of such hazards it is imperative that the design be such that no leakage can occur. In addition these vessels have to be designed carefully to cope with the operating temperature and pressure. It should be borne in mind that the rupture of a pressure vessel has a potential to cause extensive physical injury and property damage. Plant safety and integrity are of fundamental concern in pressure vessel design and these of course depend on the adequacy of design codes. When discussing pressure vessels we must also consider tanks. Pressure vessels and tanks are significantly different in both design and construction tanks unlike pressure vessels are limited to atmospheric pressure and pressure vessels often have internals while most tanks do not and those that do are limited to heating coils or mixers .
