Basic Info.


For PPR pipe, there are two parameters: pipe diameter and wall thickness.

For PPR pipes, the pipe diameter is the size of the pipe diameter. In the field of home improvement, the commonly used PPR water pipe diameters are water pipes with an outer diameter of 20mm, 25mm, and 32mm.

As for the wall thickness of the water pipe, it is usually marked behind the diameter of the water pipe, such as 25×3.5mm, 25×4.2mm. These are the two common wall thickness specifications for 25 gauge pipes.

1. Mechanical properties
Good mechanical properties are an essential element for high-quality PPR pipes. Since it is used in the water supply system, the PPR pipe needs to withstand a certain water pressure for a long time, so the most important mechanical property of the PPR pipe is the pressure resistance. There are many factors affecting the mechanical properties of pipes, which are related to equipment and technology, the uniformity of mixing materials, and the performance parameters of raw materials.

2. Corrosion resistance, anti-scaling
Corrosion resistance and anti-scaling are the basic needs of daily water for pipelines. Good PPR pipes have better chemical corrosion resistance and can resist the erosion of chemical elements in the water. At the same time, the smooth inner surface can avoid the formation of scale, making the transported water more clean and hygienic.

3. High temperature resistance, high pressure resistance
The melting point temperature of relatively pure PPR raw materials is 220 ° C. If other impurities are added to the raw materials during manufacture, the melting point of the mixture will drop, resulting in a drop in the softening point. This means that the water pipes tend to become soft at lower temperatures, thereby reducing their ability to withstand pressure. PPR water pipes with good materials will not have this problem.

4. Easy to weld
PPR pipes made of high-quality PPR raw materials are easier to weld, and the welding openings expand evenly during welding, making the welding firmer. Because the melting point of the PPR water pipe mixed with impurities decreases, the melted part tends to become thin and soft during welding, and it is not easy to socket and insert during welding, which affects the welding quality and also causes the passage of the water pipe to become smaller. 

5. Solid materials
The wire mouth used in good PPR metal pipe fittings is made of high-quality brass material, and the amount of brass will not cut corners to ensure the safer and more reliable operation of the piping system.

Pipes often need to use different connection methods according to the occasion of use and material characteristics. The connection of the PPR pipeline adopts the method of hot melt, which is characterized by easy and fast operation and simple tools. And, since binding at the molecular level is possible, very reliable connections can be easily achieved by simply doing what is required. So what other commonly used connection methods? What are the characteristics of various connection methods?

1. Flange connection
Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate, then add a flange gasket between the two flange plates, and finally tighten the two flange plates with bolts. A detachable joint which is tightly combined.

The main features of flange connection are easy disassembly, high strength and good sealing performance. When installing the flange, it is required that the two flanges be kept parallel, and the sealing surface of the flange should not be damaged and should be cleaned up. Flange gaskets should be selected according to design regulations.

Flange connections are often used for pipes with larger diameters. Flange connections are generally used in main road connecting valves, check valves, water meters, water pumps, etc., as well as pipe sections that need to be disassembled and repaired frequently.

2. Welding
Metal pipes are often connected by welding. Welding is a manufacturing process and technology for joining metals by heating, high temperature or high pressure, usually in the following ways:

Fusion welding - heating the workpieces to be joined to locally melt to form a molten pool, and if necessary, a filler can be added to assist, and the molten pool is cooled and solidified before joining.
Pressure Welding - The welding process must apply pressure to the weldment.
Brazing - use a metal material with a lower melting point than the base metal as the brazing filler metal, use the liquid brazing filler metal to wet the base metal, fill the joint gap, and diffuse with the base metal to connect the weldment.

Welding is suitable for metal pipes, and is mostly used for concealed pipes and pipes with larger diameters. When the pipe diameter is less than 22mm, socket or sleeve welding should be adopted, and the socket should be installed facing the flow direction of the medium. When the pipe diameter is greater than or equal to 22mm, butt welding should be used.

The biggest problem with welding is the risk of causing corrosion, and the welded joints are prone to rust under long-term use. Welding quality is highly dependent on welding technology, and it is difficult to control the quality of pipe connections stably.

3. Snap-on connection
Compression connections are commonly found in thin-walled pipe connections. It adopts radial contraction external force (hydraulic pliers) to clamp the pipe fittings on the pipe, and seals water through the O-ring to achieve the connection effect. Similar principles are also ring pressure connection.

The compression type connection is easy to install, but it is more suitable for the exposed pipes of the cold water system and the direct drinking water system. Because it is more troublesome to replace the sealing ring in the tube when it is aging. The hot water system should be avoided as much as possible, because the thermal expansion and contraction properties of the sealing ring and the metal material are different, and the sealing ring is more prone to aging after the cold and heat cycle. Therefore, concealed pipes and hot water systems are generally not recommended for pipes with this connection.

4. Threaded connection
The threaded connection adopts the method of tightening the two connectors with the inner and outer interfaces of the conical pipe thread, and the connection effect is achieved by the pressure sealing of the thread of the connection port. It is widely used in traditional galvanized steel pipes.

Threaded connections are suitable for galvanized steel pipes with a pipe diameter less than or equal to 100mm, and are mostly used for exposed pipes. Because the thread of the threaded connection often damages the surface of the galvanized layer, it is very easy to cause corrosion of the pipeline.

5. Socket connection
Socket connections are mainly used for cast iron pipes, concrete pipes, ceramic pipes, plastic pipes, etc. with socket joints. There are two types of flexible connections and rigid connections.

Rigid socket connection is to insert the socket of the pipe into the socket of the pipe. After alignment, use caulking material to caulk first, and then seal it with sealing material. The rigid connection is sealed with asbestos cement or expandable packing. It becomes a solid closed whole.

The flexible socket connection joint puts an elastic rubber ring on the seal stop of the pipe socket, and then applies force to insert the pipe spigot to form a closed pipe that can adapt to a certain range of displacement and vibration.

6. Groove connection
Grooved connection, also known as clamp connection, can be used for the connection of galvanized steel pipes with a diameter greater than or equal to 100mm in fire water, air conditioning hot and cold water, water supply, rainwater and other systems. It has the characteristics of simple operation, does not affect the original characteristics of the pipeline, safe construction, good system stability, convenient maintenance, labor-saving and time-saving.

7. Hot melt bonding
The pipe connection method used by the PPR pipe during hot melt connection is to use the heating method to make the PPR connection part reach the melting point to melt, and the pipe and the pipe fittings are fused together by the socket method.

The hot-melt connection is a permanent connection with strong reliability, and once the hot-melt is completed, there will be almost no water leakage accidents. It is precisely because of this reliable connection that PPR pipes have been widely used.

8. Electrofusion connection
Electrofusion connection is generally a connection method used for welding PE pipes. By electrifying and heating the copper wire embedded in the inner wall of the pipe fitting, the plastic resin in the fusion zone undergoes a phase change, the polymer segments penetrate each other under a certain pressure, and the cross-linking is strong, and the cooling material is re-crystallized and arranged to combine the fusion parts into a whole. .

Compared with electrofusion welding, the quality of hot melt welding can be directly expressed by the amount of flanging and peeling. The welding strength and welding stability are relatively high, and the quality of the welded pipeline can be basically guaranteed by checking the welding joint. Capacitor welding uses the internal melting of the electrofusion sleeve to connect the two nozzles. Due to the wrapping of the electrofusion sleeve, the quality of the welding opening cannot be directly seen from the outside, but only indirectly through the observation hole to indicate the length of the column. To judge whether the electrofusion welding process is completed, the quality inspection of the butt welding joint can only be done by the pipeline through the pressure test.
