压力容器是石油、化工,化肥、电力、冶金、轻工、医药等各工业领域中广泛使用的一种承压设备,如果这些设备在制造和运行中得不到可靠的质量保证,一旦发生事故,破坏性非常大,其危险程度是无法估计的,会给国家、企业和人民生命财产带来巨大的损失。因此我们必须对压力容器涉及的各质量环节进行全过程控制,才是防止事故发生的根本。 Pressure vessel is a pressure-bearing equipment widely used in petroleum, chemical, fertilizer, electric power, metallurgy, light industry, medicine and other industrial fields. If these equipments can not get reliable quality assurance in manufacture and operation, , The destructiveness is very large and the degree of danger is incalculable, which will bring huge losses to the life and property of the country, enterprises and people. Therefore, we must control the quality of the pressure vessel involved in all aspects of the whole process, is to prevent the root cause of the accident.
