随着国家的科技进步和经济发展, 大型容器、加氢反应器等厚壁高温高压产品逐渐增多, 质量要求也更加严格, 一些大型容器需要在施工现场进行理化检验。由于施工现场设施简陋, 环境因素变化无常, 理化检验的质量控制就显得尤为重要。只有正确地掌控现场理化检验的各个因素, 才能得到精确的现场理化检验数据, 出具准确的检测报告。

With the development of national technology and economy, more and more thick wall products were produced, which could bear high temperature and high pressure such as heavy vessels and hydrogenation reactors. Stricter requirements were put forward to keep good quality of the products. Physical and chemical tests of large vessels should be carried out on construction site. Due to the simple facilities and changeable environment of the construction site, the quality control of physical and chemical tests was especially important. Only when each factor of physical and chemical tests on site was accurately controlled, the accurate data of physical and chemical tests on site could be obtained and accurate testing reports could be issued.
