Background
In life production, a connecting flange is often used in the butt joint of pipelines, and pipelines in different sections are butted to achieve the purposes of prolonging the erection length of the pipelines and changing the direction of the pipelines. However, most of the conventional pipe connection flanges cannot be adjusted in direction after being butted, and further have the following disadvantages.
Inconvenient layout adjustment: once the flanges are butted, the direction cannot be adjusted, the layout of the pipeline connection is possibly fixed, adjustment and change cannot be carried out according to actual needs, and the flexibility of a pipeline system is limited.
The connection difficulty is increased: if the pipeline system is required to be changed or expanded, the direction of the flange connection cannot be adjusted, so that the pipeline parts may need to be redesigned or replaced, and the connection difficulty and the workload are increased.
The maintenance difficulty is increased: in the pipeline operation process, if the pipeline parts of the connecting part need to be maintained or replaced, the direction of the pipeline parts cannot be adjusted, so that the surrounding pipelines may need to be disassembled and reassembled, and the maintenance difficulty and the workload are increased.
Leakage may occur: the butt joint between the pipelines has the condition that the angle needs to be finely adjusted, and in the butt joint process, gaps can appear at the joint parts due to the finely adjusted direction, so that the flange is not tightly sealed, and the risk of liquid or gas leakage is caused.
