Wanfang PVC-U drainage pipe is made of health grade PVC resin as the main raw material, adding a proper amount of stabilizer, lubricant, filler, color additive, etc. to be extruded by plastic extruder and injection molded by injection molding machine, and completing the production of pipes and pipe fittings through cooling, curing, shaping, inspection, packaging and other processes. It has excellent physical and chemical properties, chemical corrosion resistance, high impact strength, small fluid resistance, 30% higher flow rate than cast iron pipe of the same diameter, aging resistance, long service life, and is widely used in various systems such as internal and external buildings or buried drainage, industrial sewage, ventilation pipeline, etc.
Unplasticized polyvinyl chloride (PVC-U) pipes for building drainage GB / T 5836.1-2018
Unplasticized polyvinyl chloride (PVC-U) pipe fittings for building drainage GB / T 5836.2-2018
Key words: safety, long life, corrosion resistance, self extinguishing, frost resistance, convenient installation, water tightness
1. The surface hardness and tensile strength of the pipe are excellent, and the safety coefficient of the pipe is high.
2. good aging resistance.
3. The friction coefficient of the pipeline is small, the water flow is smooth, it is not easy to block, and the maintenance workload is small.
4. Good corrosion resistance and drug resistance. PVC-U pipe has excellent acid, alkali and corrosion resistance, and is not affected by moisture and soil pH, so no anti-corrosion treatment is required when laying the pipe.
5. The material has high oxygen index and self extinguishing property.
6. The linear expansion coefficient of the pipeline is small, which is 0.07mm / ℃, and the deformation affected by the temperature is small. The coefficient of thermal conductivity and modulus of elasticity are small, and the frost resistance is better than that of cast iron drain pipe.
7. The connection of pipes and pipe fittings can be glued, the construction method is simple, the operation is convenient, and the installation efficiency is high.
8. Good water tightness: the installation of PVC-U pipe has good water tightness whether it is glued or rubber ring connected.
It can be widely used in municipal engineering, construction engineering, industry, agriculture, garden engineering, road engineering and other fields.
For the indoor and outdoor drainage pipeline works of industrial and civil buildings, the temperature of the continuous discharged domestic sewage is not far more than 40 ℃, the temperature of the instantaneous waste sewage is not far more than 80 ℃, and the industrial sewage that does not rust the pipes can be used.
1. Wipe the pipe spigot and pipe fitting socket before connection
2. Measure the depth of the socket and mark the pipe
3. Apply adhesive, apply socket first, then spigot, coating evenly, appropriate amount
4. Align the direction, insert into the scribed part once, rotate 1 / 4 turn
5. Wipe the excess adhesive at the interface
6. Set the stuck pipe to the joint to solidify the pipe cutting: after measuring the appropriate length of the pipe, it can be cut by hand saw or machine. After cutting, the two sections should be kept flat. Use butterfly file to remove the burr and chamfer, and the chamfer should not be too large.
