为了解决在大化肥生产装置中合理利用凯特克(HYTORC)液压扭矩扳手对设备螺柱进行预紧的问题,本文对尿素合成塔水压试验时螺柱预紧力矩的计算以及凯特克(HYTORC)液压扭矩扳手在尿素合成塔螺柱预紧工作中的应用,为今后合理利用凯特克(HYTORC)液压扭矩扳手对设备螺柱预紧总结经验。
In order to solve the problem of pre-tightening the equipment studs with HYTORC hydraulic torque wrench in the large fertilizer production plant, The application of hydraulic torque wrench in the prestressing of studs in the urea synthesis tower will provide lessons for the preconditioning of equipment studs for the reasonable utilization of HYTORC hydraulic torque wrenches in the future.
