1. After the measured length of Ball Valve Manufacturers is determined, you can use a hacksaw to cut a saw manually or a circular saw blade or a sawing machine to cut a saw.

2. One expansion joint is installed on each layer of the riser to compensate for the thermal expansion and cold contraction of the counter current pipe. Thirdly, pay attention to the direction along the water when installing the tee, so that the slope can be formed naturally when installing the horizontal pipe. If the height of each layer of the riser is less than 3m, consider setting a pipe hoop.

3. For the bonding test of PPR pipe fittings, the end of the outer pipe with a length of about 50 mm and the wall of the pipe fitting bearing interface must be cleaned before assembly, and then the end of the outer pipe and the wall of the pipe fitting bearing must be uniformly brushed and scrubbed with acetone cotton, and then the adhesive must be evenly coated on both of them without omission After that, rotate to the ideal combination angle to insert the pipe into the socket of the pipe fitting. Knock the pipe with a mallet to fully insert the pipe into the socket. Do not disassemble or change the direction within two minutes. Wipe off the extrusion glue in time to keep the pipe clean. The straight-line distance of horizontal pipe and drain pipe shall meet the requirements, and the inspection port or cleaning port shall also be set.
