How to properly regulate the fastening flange bolts

First, as ready fastening flanges need to use tools including wrenches (wrenches and adjustable wrench) bolts, flanges and other related tools
Next, as shown in the bolts had to be put away tight gasket, and then another flange smooth on top, each one bolt hole to be aligned. Do not place the note after a smooth touch flange.
Next, the most important is when the bolt according to the angle, the first hand hold the bolt diagonal, until the flange can not shake up, note that at this time to guarantee the correctness of the position of the gasket.
Then, tighten the bolts with a wrench vigorously, until it stops, then the note is facing tight angle, while tight look, or the other side will tilt.
Then, another bolt also installed on the diagonal, the same is also a tight angle, while tight look, head to prevent warping.
Finally, all the bolts are eleven strengthened by diagonal sequence tighten again to prevent loosening, after adding other connections to such protection does not leak fastening flanges.

Something about flange

Flange, also known as flanges or flange flange. Flanges are interconnected between the tube and pipe parts for the connection between the pipe ends; import and export are also useful in the device on the flange for connection between the two devices, such as the reducer flange. Flange connection or flange joints, is defined by the flanges, gaskets and bolts of the three interconnected as a combination of a set of detachable connection seal structure. Pipe flange means plumbing fixtures in piping flanges, with import and export flange on the equipment means equipment. There are holes on the flange, so that the two flange bolts tightly connected. Between the flange sealing gasket. Threaded flange connection points (threaded connection) flanges, welded flanges and flange clip. Flanges are used in pairs, low-pressure pipe flange can be connected using wire, four kilograms more than the pressure of the use of welding flanges. Between the two flange gaskets, and then secured with bolts. Different flange thickness at different pressures, the bolts are used is also different. Pumps and valves, and pipe connections when local these facilities and equipment, but also made the corresponding flange shape, also known as the flange connection. Any use of the two planes simultaneously closed around the bolted connection components, generally known as the "flange", such as connecting ventilation ducts, this type of parts can be called "flange parts." But this is only a partial connection devices, such as flanges and pump connections, bad water pump called "flange parts." Relatively small, such as valves, etc., can be called "flange parts."
