What type of PPR pipe is used for home improvement water and electricity renovation

Hello, it is home decoration, bathroom and stove room, hot and cold water, generally with 20 Weixing ppr pipes, heating with 25 ppr hot water pipes.

It depends on what area you are in. In some places, 20 (4 points) is used, and in some places 25 (6 points) is used. Look at the caliber of the main pipe in your home. Like Shanghai, they are all in charge of 6.

Depending on how big your area is, the general supervisor uses 25 (6 in charge) and the branch pipe uses 20 (4 in charge).

Summary. Hello dear! The difference between PPR pipe and PPC pipe is that PPC contains chlorine and is toxic, and the stability is not as high as PPR. Aluminum-plastic pipes generally have three layers, the surface layer is protected, and the middle aluminum pipe is an anti-corrosion layer. PPR is relatively expensive, and now home decoration is used as water pipes.

The difference between PPR pipe and PPC pipe for home improvement.

PPR, PPC are polypropylene plastics, in the international standard, polypropylene hot and cold water pipes are divided into PP-H, PP-B, PP-R three kinds, no PP-C. The PP-C pipe on the market is actually a PP-B pipe, and its raw material is a special material for block copolymer polypropylene pipes. PP-B pipe is a kind of hot and cold water pipe, which is relatively cheap, and its heat resistance and pressure resistance are very different from PP-R.

For example: the use of conditions classification 2, the design of pressure pipes, PP-R pipe wall thickness, PP-B (PP-C) pipe wall thickness; Design pressure, PP-R pipe wall thickness, and PP-B (PP-C) is not available. Because the required wall thickness is too thick.

The PP-C pipe with the same structure size as PP-R on the market has much lower use conditions, and cannot be mixed with PP-R pipe, let alone replace PP-R pipe with PP-C pipe after determining the use conditions. Condition 2 indicates the design temperature of 70, for hot water.

1. The material is different PPC, also known as polymethyl ethylene carbonate, which is a fully degradable and environmentally friendly plastic synthesized from carbon dioxide and propylene oxide. PPR, commonly known as type III polypropylene, is a random copolymer polypropylene synthesized by (PP and PE) gas phase method, and is also an environmentally friendly material. 2. Different uses PPC is used to increase the toughness of some epoxy resins, and is used as a sacrificial adhesive in the ceramic industry, decomposing and evaporating during the sintering process.

It is also suitable for the preparation of dielectric materials and piezoelectric ceramics and other electric porcelain, and the composite of polycarbonate and starch (PPC starch) is used as biodegradable plastics. PPR is one of the most widely used water supply pipes in home improvement projects, which can be used for drinking water transportation. It is widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.

First of all, PPR water pipe, as a new type of water pipe material, and he has a unique advantage. PP R water pipe can be used as a cold water pipe or as a hot water pipe. Because of its light weight, pressure resistance and corrosion resistance, it has become a more commonly used material.

It is also suitable for some hot water pipes, even pure drinking water pipes. Generally, PVC material is a kind of plastic decorative material. It has the characteristics of light weight, heat and heat insulation, moisture and flame resistance, and easy construction.

PPR pipe specifications are indicated by pipe series S, nominal outer diameter DN and nominal wall thickness EN.

For example, PPR pipe series S5, PPR nominal outer diameter DN25mm, PPR nominal wall thickness is expressed as S5, DN25

PPR pipe series S: It is a dimensionless numerical series used to represent the specifications of PPR pipes, and there is the following relationship S=(DN-EN) 2 EN

Wherein: dn - PPR nominal diameter (inner diameter), the unit is mmen - PPR nominal wall thickness, the unit is mm

Generally, the commonly used PP-R pipe specifications are five series.

Because the functions and performance of rooms, electrical appliances and other functions and performance cannot be achieved, the requirements for the Hongqin models of water and electricity pipes are not the same, so what are the models of water and electricity pipes for decoration?

1. Water supply pipe.

The water supply pipe has cold water pipe and heat shrinkable pipe, and the commonly used water pipe for home improvement is ppr 25 hot water pipe.

Accessories are: 25 gate valves, 25 pipe clamps, 25 inner wire elbows, 25 outer wire elbows, 25 direct, 25 inner wire tees, 25 outer wire tees, bridge bending reeds, plugs, raw tape, tees, 90° elbows, 45° elbows, conjoined elbows, etc.

2. Drainage pipe.

There are 110 pipes, 75 pipes, 50 pipes, 11090° elbows, 11045° elbows, 110 direct, 110 tees, 110 water traps, 11075 cores, 11050 cores, 11075 tees, and 11050 tees. 7590° Elbow, 7545° Elbow Sale, 75 Water Elbow, 75 Direct, 75 Tee, 7550 Core Filler, 5090° Elbow, 5045° Elbow, 50 Direct, 50 Tee, 50 Water Elbow, and Glue, etc.

3. Strong and weak current system.

Back box: The bottom box is divided into two models, one is 86 type and the other is 118 type.

Threading pipe: There are 16 pipes and 20 pipes, yellow wax pipe. The threading pipe is divided into colors, strong and weak electric colors, commonly used red and green, red and blue, and accessories are: direct, lock, pipe card.

Wire: combustion-supporting phoenix copper core wire, with specifications of 6 square, 4 square, square, square;

Weak current: TV lines, lines, network cables, speaker cables, etc.
