FRPP pipeline installation process

FRPP pipeline installation process

FRPP pipeline measurement, marking and positioning: According to the actual situation of the site, draw the installation direction of the PP pipeline at the construction site according to the construction drawings, and reasonably determine the installation distance of the pipeline supports and hangers and the actual location of the site according to the specifications, and draw the pipeline concisely Large installation connection diagram for the next process.

FRPP pipe riser installation: Hang the wire before installation of the riser, make sure that the riser can pass through the reserved hole without hindrance (otherwise, correct the reserved pipe hole until the riser can pass through), and reasonably determine the riser on the wall The position of the bracket makes the verticality of the pipeline meet the requirements of Table 5.2.16 in GB50242-2002. Select the appropriate PP pipe fittings according to the floor height, the installation height of the drainage branch pipe, the installation height of the vertical inspection port and the position where the PP pipe meets other drainage pipes. After determining the installation sequence of the pipes (install from top to bottom or from bottom to top) , while playing the bracket, while prefabricating the connecting pipe. After the bracket is installed, tie one end of the prefabricated connecting pipe to the hemp rope and hang it on the wire to reduce the operation load and speed up the installation of the pipe.

Installation of pipe supports and hangers for FRPP pipelines: The installation positions of supports and hangers are reasonably determined according to the direction of the pipeline. The spacing between pipe supports and hangers should meet the requirements of Table 5.2.9 in GB50242-2002, and ensure that each pipe fitting is not stressed and meets the requirements Drainage slope requirements. When metal pipe clamps are used for the support and hanger pipe clamps, the pipe clamps and the pipe support should be protected by rubber pads.
