Plastic pipe laying points plastic pipe brand recommended

Plastic pipes, as the name suggests, are made from plastic materials. It is very extensive in everyday home use. With corrosion resistance, light weight, high compressive strength, and more hygienic safety, environmental protection and health, water flow through plastic pipes will also reduce a lot of resistance. Next, Xiaobian introduced the main points of plastic pipe laying and the brand recommendation of plastic pipes.

Plastic pipe laying points

1. When the plastic pipe is laid and connected, the construction environment temperature should not be lower than -5°C;

2, the choice of pipe material should meet the following requirements:

1) The specifications and materials of the pipe should meet the current national standards and design requirements;

2) The normal temperature environment should choose PVC (PVC-U) plastic pipe;

3) In rodent and termite areas, plastic pipes with appropriate protection capabilities should be selected;

3, plastic pipe group should meet the following requirements

1) The tube group should be rectangular, and the number of horizontally arranged tube holes should be an even number. When two plastic laying tubes are to be placed, they should be discharged in a “one” shape; when the plastic tube is three, it should be “product” type. Emissions; when the number of plastic pipes is greater than 3, the stacking mode should be adopted;

2) The height of the rectangle should not be less than the width, but it should not be more than double;

3) Pipes with large inner diameter of the pipe hole should be placed on the lower side and outer side of the pipe group. Pipes with small inner diameter of the pipe hole should be placed on the upper side and inner side of the pipe group;

4) In the case of multiple porous tube groups, 10~20mm gaps should be left between the tubes, 50mm gaps should be left between the porous tubes when entering the human pores, and 20mm gaps should be left between the single-hole corrugated tubes and solid wall tubes. All the gaps should be Subdivision

5) The pipe position between two adjacent manholes should be the same, and the cross section of the pipe group should meet the design requirements;

4, pipeline laying should meet the following requirements

1) When the pipeline enters the manhole, the net distance from the top of the pipeline to the top surface of the manhole is ≥300mm, the net distance from the bottom of the pipeline to the floor of the manhole is ≥400mm, and the pipe leading into the manhole is preferably covered by the top. Within the range of ~400mm, and staggered with the position where the pipe enters;

2) The length of the straight pipeline should be ≤ 200m, the length of the straight pipeline on the high-grade highway should be ≤ 250m, and the length of the curved pipeline should be ≤ 150m;

3) When the plastic pipe is laid, the curved pipe may be laid and the radius of curvature may not be less than 15m. It is forbidden to heat and bend the plastic pipe; S-shaped bends (that is, reverse bending) are forbidden in the same pipe; The joints should be arranged in straight sections. If it is unavoidable, the joints should be partially or fully encapsulated.

4) When the pipe enters the hole of the hand (hand), the nozzle shall not protrude from the inner wall of the hand (hand) hole, and it shall terminate at 100mm from the inside of the wall, and shall be tightly sealed and the nozzle shall be made into a bell mouth.

5) The plastic pipe should be manually transferred into the ditch, and it is forbidden to roll into the ditch or use a rope to hang in the hole.

5, plastic pipe connection should meet the following requirements

1) The signage of the plastic pipe should face upwards;

2) The connection of plastic pipes should adopt socket-type bonding and socket-inserted elastic sealing rings; the length of socket-type pipe joints should be ≥200mm;

3) The inner and outer walls of the socket of the porous plastic pipe should be evenly coated with a special neutral glue adhesive, and the plastic pipe should be inserted in the end and squeezed firmly;

4) The interfaces of plastic pipes should be staggered, and the distance between the joints of two adjacent pipes should not be less than 300mm; the pipe joints in the curved part of the pipe should be reinforced;

5) The corrugated tube and silicon core tube should be bundled once with a spacing of about 3m with a Lex band. The plum tube should be stratified and arranged neatly; when the tube group is smaller than two layers, the whole bandage is tied; when there are more than two layers, two adjacent layers For a group of lashings and then banding;

6) The cutting of plastic pipe is based on the size of the pipe diameter, and different sizes of pipe cutters are used. The cross-section of the pipe should be perpendicular to the center of the pipe and it should be straight and free from burrs.

7) The connection of the single-hole corrugated plastic pipe should be connected with the elastic gasket of the socket; before performing the connection operation, check whether the sealing ring is intact, clean the inner and outer ports of the socket, and then place the sealing ring on the socket. In the middle of a ripple groove, the direction should not be reversed. Apply a small amount of soapy water to the socket and insert the socket end into the socket until it is firm.

Plastic pipe brand recommended

1, Liansu

Because of the rapid development of plastic pipes, it also allows a number of plastic pipe brands to rise. The brand scale has also been further expanded. New materials, new types of research and development products, and emerging markets, advanced design concepts have emerged in an endless stream. This has also made the performance of plastic pipes clearer, and the field of popularization and application has been further expanded. And in China's plastic pipe brand in the plastic pipe industry, one of China's top ten pipeline brands. Headquartered in Guangdong, the merger and acquisition of a lot of small management companies, consumers think plastic pipe brand Liansu, quality is very small, but the price is a bit high.

2, Yatong

The plastic pipes of the Asia Tong brand are also the old brands of the pipe industry. Most of them are based on drainage pipelines and are strictly designed according to standards. However, they live in the southeast and have not expanded their own business territory. The temperature is not hot, the market operation and sales model are not clear. In short, this plastic pipe brand is also one of China's top ten pipe brands, with excellent quality, affordable, standard and personalized design, demonstrating the exquisite technology.

3. Rifeng

In China's pipeline survey, the share of plastic pipelines accounts for about 30% of the entire pipeline industry, and today it is still rising. Most of the construction rainwater drainage pipes are plastic pipes, building drainage, and urban drainage. Water supply pipelines have almost reached 60% usage rate, showing that the trend of plastic pipelines is large. The day of the plastic pipe brand is one of the top ten brands in the pipeline industry. There was also a period of great glory. The brand of plastic pipes was of high quality and slightly higher prices.

Editor's summary: The points on the laying of plastic pipes and brand recommendations for plastic pipes are introduced here. I hope to help everyone. If you want to know more related information, you can pay attention to this website information.
