What do I need to pay attention to when installing disassembly joints?

Disassembly joints can prevent pipeline leakage and damage of compensation joints due to excessive displacement, and are mainly used for loose-fitting connections of pipelines that absorb axial displacement and bear axial pressure thrust within the allowable displacement range.
The function of disassembly joint is to add a limit device to the original performance and lock it with double nuts at the oversized expansion and contraction. The pipe can be freely expanded and contracted within the allowed expansion volume, and once the oversized expansion volume is exceeded, it can be used as a limiting device to ensure the operation of the pipe. The disassembly of the joint installation requires us to pay attention to the following points.
1 . Loosen the pressure plate bolt before installation, stretch the disassembly joint to the installation length, and then tighten the bolt diagonally, do not press the deviation.
2 . The disassembly joint should be installed between two fixed brackets on the straight section of the pipe, and there should be no guiding bracket and gear to ensure the normal expansion and contraction of the disassembly joint and prevent pulling off.
3 . The disassembly joint is made of good steel, and the operating temperature of the disassembly joint is 150℃-300℃. The pressure range of the disassembly joint is 1MPa, 1.6MPa.
4 . Before installing the disassembly joint, loosen the pressure plate bolt, pull the disassembly joint to the installation length and tighten the pressure plate bolt by diagonal method, do not press the deviation, then, connect the two ends of the product. The automatic expansion joint of disassembly joint is suitable for both sides are connected with flange. When installing, adjust the connection length of both ends of the product, tighten the gland bolts diagonally and evenly in turn, and then adjust the limit nuts, so that the pipe can be freely expanded and locked the expansion amount, thus ensuring the operation of the pipe.
