Good effect of flange fixed torque fastening technology

"After the steam pipe network overhaul this year, after the full implementation of the new fixed torque technology and fastening, the steam pipe network was put into operation to achieve zero leakage, which not only ensured that the steam pipeline was successfully put into operation at one time, but also eliminated the valve and bolt hot tightening link, saving manpower and improving To improve the reliability of the equipment, and realize the safety and green overhaul of the steam pipe network

Due to the daily operation of the device, the steam load cannot be stopped for a short time, and the maintenance of the main road and branch of the steam pipe network is difficult to carry out.

In order to further improve the refined management level of the overhaul, combined with the previous overhaul experience, this overhaul, the Department of Thermoelectricity will comprehensively promote the application of flange fixed torque fastening technology during the overhaul of the thermal pipe network

The flange fixed-torque tightening technology uses (manual, pneumatic, hydraulic) torque wrenches to operate in the order of tightening screws to ensure that the flange gap standards meet the requirements, so that the maintenance management is more standardized, standardized and refined, and the quality of maintenance is improved.

Before implementing the fixed torque tightening technology, after the pipeline is put into operation, the maintenance personnel must be contacted in time to heat tighten the replaced valve flange bolts.

"Flange fixed-torque tightening technology not only ensures accurate torque output, but also proper flange tightening, achieving a one-time maintenance and installation work, and greatly improving work efficiency
