Pipeline installation should be cleared one by one before the sand inside the pipe scrap iron and other debris, design documents with special requirements of the pipeline should be in accordance with the requirements of the design documents to clean up.
The openings in the pipes shall be completed before the pipes are installed. When the holes are opened in the installed pipes, the foreign matters arising from the cutting shall be cleaned to prevent entry into the pump.
Pipes connected to the pump unit shall be installed from the side of the pump unit and the pipe supports shall be installed first. The weight and additional torque of the pipes and valves shall not be applied to the pump unit. If the medium is different from the ambient temperature, Expansion joints shall be provided.
And the connection of the pipeline and the support of the pump, the hanger is completed, should be removed on the flange flange bolts in the free state of all the bolts should be able to pass through the bolt hole; flange sealing surface tolerance between the parallelism, Allowable deviation of coaxiality should be specified in the design document or product technical documents. Pairing the flange surface in the free state spacing, in order to be able to smoothly insert the gasket and the minimum distance is appropriate.
Pipeline and pump unit connection, should check the original pump to find the accuracy of the original, when the pipe connection caused by deviation, should adjust the pipe and its bracket and so on.
Pumps mentioned above include: self-priming pump, centrifugal pump, pipeline pump, screw pump, submersible pump, submerged pump.
