带压堵漏（在线密封）技术起源于英国，国内从1984年开始使用不停车带压堵漏技术，今天此技术广泛应用于电力、化工企业，成为企业实现长周期、无泄漏的重要手段，同时避免停车的物料排泄不仅给企业带来巨大的经济效益，而且有着巨大的环保意义。
The technology of plugging with pressure (on-line sealing) originated in the UK. In China, the technology of plugging with pressure without stopping has been used since 1984. Today, this technology is widely used in electric power and chemical enterprises, and becomes an important means for enterprises to realize long-term and no leakage. At the same time, avoiding the discharge of materials for stopping not only brings huge economic benefits to enterprises, but also has great environmental protection significance.
带压堵漏通常需要制作和安装卡具，然后通过专门的注胶工具，把专用带压堵漏密封胶注入卡具，形成密实的充填物，形成新的密封。我公司在长达十四年的带压堵漏施工中，积累了许多经验，在温度550℃、压力16Mpa的条件下，都进行了成功的带压堵漏，并拥有了注剂堵漏、磁压堵漏、胶粘堵漏、顶压堵漏和建筑堵漏多种带压堵漏手段。
It is usually necessary to make and install clamps for plugging under pressure. Then, special sealant for plugging under pressure is injected into the clamps through special glue injection tools to form a dense filler and a new seal. Our company has accumulated a lot of experience in the construction of plugging under pressure for up to 14 years. Under the conditions of 550 ℃ and 16MPa, we have successfully plugged under pressure, and we have many means of plugging under pressure, such as injection plugging, magnetic pressure plugging, adhesive plugging, top pressure plugging and building plugging.
