Introduction to the function of double flange force transmission joint
Loose sleeve force transmission joint is made by adding flange short pipe and force transmission screw on the basis of flange loose sleeve compensation joint. The difference between this type of compensation joint and loose sleeve compensation joint and loose sleeve limit compensation joint is that its compensation amount refers to the adjustment amount during installation and disassembly. Once all nuts are tightened, it is rigidly connected and can transmit axial force, thereby protecting equipment such as valves and pumps.
Scope of application of double flange force transmission joint
The C2F/VSSJAF double flange transmission joint is suitable for transporting media such as seawater, fresh water, hot and cold water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, finished oil, air, gas, steam and granular powder with a temperature not exceeding 250 degrees.
Brief installation instructions for double flange force transmission joints:
The C2F/VSSJAF double flange force transmission joint is suitable for pipelines connected to flanges on both sides. During installation, adjust the installation length of the product at both ends and the flange, and tighten the pressure bolts diagonally and evenly to make it a whole with a certain displacement. It is convenient for installation and maintenance, and can be adjusted according to the on-site dimensions. During operation, the axial thrust can be transmitted to the entire pipeline.
