Ppr pipe specifications explain how to select and install ppr pipes
Water pipe Gully gratings are metal or plastic grates that are used to cover and protect gully openings in the ground. These openings are typically found along roadsides, sidewalks, or other areas where water runoff needs to be collected and directed to a drainage system.

Ppr pipe specification one, ppr pipe specification introduction
1, the general home water pipe specifications are: DN15 (4 in charge), DN20 (6 in charge), DN25 (1 inch tube), DN32 (1 inch 2 tube), DN40 (1 inch half pipe), DN50 (2 inch pipe), DN65 (2-inch half pipe), DN80 (3-inch pipe), DN100 (4-inch pipe), DN125 (5-inch pipe), DN150 (6-inch pipe), DN200 (8-inch pipe), DN250 (10-inch pipe), etc. .
2, the water pipe Φ25×1/2 means its outer diameter is 25. The actual corresponding nominal diameter is DN20 (that is, people often say 6 in charge). You can buy a 6-point faucet. You can also buy a 4 point faucet (just add a diameter between the tube and the faucet). 
3. The styles and materials of household faucets are ever-changing, but the threaded parts of the connecting faucets are divided into four points, six points, and one inch. Don't worry about buying the wrong one.
4, usually said that the 4 in charge is in terms of inches, so 4 minutes is 1/2 inch (4/8 = 1/2), and an inch = 25.4mm, so the diameter of the 4 in charge is 25.4/ 2=12.7mm, and this is the inner diameter of the so-called DN15 water pipe. 
Ppr pipe specifications Second, ppr pipe selection skills
1, "touch": whether the texture is delicate, whether the particles are uniform. At present, the PPR tube on the market is mainly composed of several colors of white, gray and green. Under normal circumstances, recycled plastic cannot be white, so many people think that white is the best. In fact, this view is more one-sided. With the improvement of technology, color is not a good standard for distinguishing ppr tubes. The quality of the pipe does not solve the problem. If it is touched, it is likely that the coarse particles are mixed with other impurities.
2, "smell": There is no smell. The main material of the ppr pipe is polypropylene. Good pipes have no odor. Poor ones have a strange smell. It is very likely that polyethylene is blended instead of polypropylene. 
3, "pinch": ppr tube has a considerable hardness, you can easily squeeze into a deformed tube, certainly not ppr tube.
4, "ç ¸": a good PPR tube, "resilience" is good, too easy to break naturally not a good PPR tube. However, the hardness is not equal to the elasticity, and we have no doubt about the PPR tube that is not broken. Because some unscrupulous manufacturers increase the hardness of pipes by adding too many impurities such as calcium carbonate, such pipes are prone to embrittlement for a long time.
5, "burn": Igniting a fire, very intuitive and very useful. The ppr tube mixed with recycled plastics and other impurities in the raw material will emit black smoke with a pungent odor. After the good material is burned, it will not only emit black smoke and odor. After burning, the melted liquid is still very clean. 
PPR water pipe specifications III, ppr water pipe installation
1, first get the line up, and then slotted on the ground, I think we should let plumbers do better, because at least people are professional, if their own water pipes leak is not great. The connection from the PPR tube is: hot melt connection. The heat melting temperature is 260 degrees. From 
2. Your installation criteria then refer to your design criteria. This is based on your home improvement design. General PPR can not be installed, the first surface installed PPR to be subject to gravity deformation, the second surface mounted PPR easily aging. If the third is a white PPR, the exposed light can easily form a breeding bacterium. So it is recommended to bury it. PPR pipes can also use the hot melt socket connection method. The pipes and fittings are completely integrated. The strength of the joints even exceeds the strength of the pipe body. As long as the construction is completed properly, the reliability is extremely high after passing the pressure test.
3, PPR tube afraid of prolonged exposure to the sun, so the installation can be properly covered with foam insulation cover, easy to use 3.4 thick hot water pipe, so more durable. Of course, the PPR management also has to choose big brands, and it is recommended to use Taurus or Kinder. 
Ppr water pipe specifications above have been introduced for you, then in the selection of the time must be more understanding, and then according to their own needs to buy on the line, otherwise, the size does not correspond, then it can not be installed, ppr water pipe How to install it, be sure to master the correct method when installing it, or ask a professional person so that you can have better protection.
Gully gratings are designed to allow water to flow through while preventing larger debris, such as leaves, trash, or rocks, from entering the drainage system. They are usually made from durable materials like cast iron or galvanized steel to withstand heavy loads and resist corrosion.
In addition to their functional purpose, gully gratings also provide a safety measure by preventing pedestrians or vehicles from accidentally falling into the gully. They are often designed with anti-slip surfaces or raised edges to enhance traction and prevent accidents.
Gully gratings come in various shapes and sizes to accommodate different gully openings and flow rates. They can be square, rectangular, or circular in shape, and may have different patterns or designs on their surface for aesthetic purposes.
Regular maintenance of gully gratings is important to ensure they remain clear of debris and allow for proper water flow. This may involve periodic cleaning or removal of any obstructions that may accumulate over time.
Overall, gully gratings play a crucial role in managing surface water runoff and preventing drainage system blockages. They provide both functional and safety benefits, making them an essential component of urban infrastructure.
