What are the most commonly used PPR pipe fittings?
1 ppr pipe diameter introduction
PPR pipe standard GB / T18742 stipulates that there are ten specifications of PPR pipe outer diameter: 20, 25, 32, 40, 50, 63, 75, 90, 110, 160 (unit: mm). Generally, three specifications of 20, 25, 32 are enough for home decoration.
S3.2 and s2.5 hot water pipes are domestic hot water pipes, with PPR standard type and PPR type. If they are used for heating, standard PPR can be used. S4 and S5 are hot and cold water pipes. Generally, we use 4 branch pipes (with a diameter of 25mm and a thickness of 3.4mm) and hot water pipes. PPR pipes are divided into C pipes and B pipes, which are mainly related to the working temperature.

The joints are: direct, equal bend, big and small head, inner wire elbow, outer straight, etc
2 ppr fitting valves
There are many kinds of valves in PPR pipe fitting, such as ball valve, globe valve, gate valve, etc. different valves have different uses. Because PPR pipe has different structure, different composition materials and pressure, various valves have different classifications in the following aspects.
Valves are divided according to their structural forms. Various valves have different structural forms. For example, stop valves have DC type, angle type, through type, etc., while gate valves have masonry type, parallel type, etc.
The valve is divided by manufacturing materials. Generally speaking, the valve is made of cast iron, cast steel and copper. The valve seat is made of copper, alloy, plastic and stainless steel.
It can be divided into vacuum valve, low pressure valve, medium pressure valve, high pressure valve and ultra-high pressure valve according to the engineering pressure.

The pipe clamp plays an important role in pipe installation, usually between 30-40 cm, so that the sub pipe will not deform during use.
4 ppr fitting faucet
ppr fitting Faucet is a popular name for water valve, which is used to control the size of water flow switch and has the effect of water saving. The renewal speed of faucet is very fast, from old cast iron technology to electroplating knob type, and then to stainless steel single temperature single control faucet, stainless steel double temperature double control faucet and kitchen semi-automatic faucet. Now, more and more consumers choose faucets, which will be comprehensively considered from material, function, shape and other aspects.
5 copper wire connector
The copper wire joint is generally used in the place where the faucet is connected, and in the place where the radiator is connected.
