带压堵漏技术是国际上70年代中期发展起来的化工设备维修技术。80年代初期我厂开始带压堵漏技术的研究，80年代中期从英国弗曼尼特公司引进带压堵漏技术。近年来，我们在不断提高带压堵漏技术的基础上，进一步加强带压堵漏的管理工作，逐步建立并完善了带压堵漏夹具设计，带压 Pressure sealing technology is the international development of the mid-70s chemical equipment maintenance technology. In the early 1980s, our factory began to research on pressure plugging technology. In the mid-1980s, pressure plugging technology was introduced from the British company Fremont. In recent years, we continue to improve the pressure on the basis of plugging technology, to further strengthen the management of pressure and plugging, and gradually establish and improve the design of pressure and plugging fixture with pressure
