Product Description

When installing the flexible composite pipe, ensure that it is not twisted. The twisted flexible composite pipe will be damaged or the joint will be loose under the action of pressure.

Product discription

Coal Mine Quick Plug Type Hose Coupling are the most convenient plug-and-play connection method, especially in some air tube connection is very inconvenient and difficult space occasions, more reflect the superiority of quick release couplings.It is widely used in the coal mining industry for pipe connection.The company can also provide RTJ150 type pipe joint for polyurethane pipeline，Customized non-standard Shaped Pipe Joints.

The correct installation of flexible composite high-pressure transmission pipe is very important to ensure the system performance and obtain the best service life. The following illustration provides the correct installation method of flexible composite pipe.

When the flexible composite high-pressure conveying pipe is installed in a straight line, enough allowance shall be reserved for the length of the flexible composite high-

pressureconveyingpipetocompensateforthelength change during pressurization.

Use appropriate angle transition joints to prevent the flexible composite high-pressure transmission pipe from being twisted or bent excessively.

High ambient temperature will shorten the service life of the flexible composite high-pressure transmission pipe, so ensurethattheflexiblecompositehigh-pressure

transmission pipe is away from high-temperature parts. If this is not possible, insulate the flexible composite high-pressure delivery pipe.

Use 45 ° or 90 ° transition joints and pipe joints directly toinstallflexiblecompositepipes.Toimprovethe convenience of installation, do not fix the bending part of the

flexible composite pipe, and do not fix the high-pressure pipeline and low-pressure pipeline together.

When connecting the end of flexible composite pipe, the flexible composite pipe shall be bent on the same plane to prevent distortion and deformation of flexible composite pipe.
