With the continuous development of science and technology, the update and iteration speed of various materials is also becoming faster and faster. The traditional ordinary cast iron drainage pipes and PVC drainage pipes can no longer meet people’s needs in terms of noise reduction. Therefore, pp pipes are used as A new type of silent pipe has been widely used. PP pipe has good physical and chemical properties, and has good impact resistance, bending fatigue resistance, high temperature resistance and acid and alkali resistance, especially this kind of pipe usually adopts socket connection.
The PP pipe is equipped with a special sealing rubber ring, which can effectively reduce the vibration between the pipe and the pipe fittings, and the mute effect is very good. When cutting the PP pipe, the end face should be flush and perpendicular to the axis of the pipe. For large-sized pipes, it is recommended to choose equipment such as grinding wheel saws and pipe cutters, while for small-sized pipes, it is more recommended to choose receipts, cutters, etc.; Use a manual grinder or a special chamfering machine to chamfer the pipe end to 15 degrees to 45 degrees. After removing the burrs, use sandpaper to smooth it. It should be noted that the thickness of the bevel is about half of the thickness of the pipe wall; Install the rubber ring, the rubber ring is in the shape of an oblique W, and it should be inclined in the direction of the pipe, which is more conducive to the socket and insertion of the pipe.
At the same time, special attention should be paid to ensure that the direction of the rubber ring cannot be installed in the opposite direction, otherwise it will lead to failure of normal installation; this step of lubrication is very important and cannot be ignored. Use a brush to apply detergent evenly on the sealing ring, socket and socket; Insert, use special construction tools, slowly insert the pipe into the pipe fitting. PP pipe is a building material that we often see in our lives. It can be seen in homes or industrial buildings. Compared with other traditional plastic pipes, the rigidity, The compressive strength should be higher, and it also has significant advantages such as light weight, corrosion resistance, hygiene and safety, energy saving, convenient installation, and long service life.
PP pipes have been widely used in the fields of chemical industry, food hygiene, environmental protection, building water supply and drainage, etc. The appearance of PP pipe is a reflection of the inherent quality of the product. If the appearance of the product is rough, there are some defects in molding, the color is not correct, there are impurities, and the quality of printing is relatively poor, it is not recommended to choose; PP pipe flexibility, when selecting samples When the pipe is cracked, you can try it with your foot to see if the pipe is brittle. Generally speaking, the better quality pipe has better toughness and can be easily bent without breaking. The inner and outer walls are smooth, and there will be no bumps and cracks. The products are more brittle, broken when bent, and the inner wall has a rough and uneven feeling.
