The correct placement of the gasket and proper tightening of bolts in a flanged joint will ensure a leak-free joint. Proper bolt tightening will ensure uniform load distribution in all bolts without damaging the gaskets. The following procedure describes how to tighten flangebolts. Flange Bolt Tig...
After reaching the final torque, use rotational tightening until all bolts are stable at the final torque value (in general, two complete times around is required). Always use the crisscross pattern! Caution! Do not use this procedure to align and/or pull the joint together. ...
The utility model provides a tightening device for a flange bolt of a high-pressure heater of a thermal power plant. The tightening device comprises a fixed component, a first connector, a second connector, an oil supply device, an oil cylinder and a knocking wrench, wherein the fixed ...

When tightening the nuts (3), the micrometer gauges (1) mounted on the ends of the bolts indicated the current value of the rod protruding above the end of the bolt. Based on such measurement, the elongation of a given bolt can be directly assessed, and after determining the ...
aValve design shall be such that the bolting of body flange joint will not obstruct the bolting of the end flanges. Gap between end flange and body flange shall be sufficient to do bolt tensioning and to use wrenches for bolt tightening. The same shall be specified in the sample drawing ...
Single-step tightening is more convenient and faster than multi-step tightening, so it is often used in flange connections. However, the elastic interaction between bolts is greater in single-step tightening compared to multi-step tightening, which leads to a more dispersed distribution of bolt loa...
