uPVC stands for unplasticized polyvinyl chloride, which is a type of piping that is made from PVC plastic. It is becoming an increasingly popular choice for water and waste water systems because of its many advantages over traditional materials like metal and concrete.
uPVC pipe is sanitary polyvinyl chloride (PVC) resin as the main raw material, add appropriate amount of stabilizers, lubricants, fillers, color enhancers, etc. through the plastic extruder extrusion molding, through the cooling, curing, shaping, inspection, packaging and other processes to complete the production of pipe.
uPVC manages acid resistant alkali, corrosion-resistant, and many chemical plant are as the transfusion pipe arrangement, the adhering junction of uPVC pipe adopts spigot and socket type bonding, the normal operation method is to determine first the mounting point and carry out mark, smear layer of adhesive on the bonding plane of pipe and link, immediately socket is inserted bellmouth again, and from axially adopt the article such as mallet to knock applied thrust to the bellmouth direction.
Good mechanical properties
PVC agricultural irrigation pipe rigidity, high resistance to external forces, buried water is not easy to be damaged by external forces.
Transmission efficiency
PVC agricultural irrigation pipe inner wall is smooth, small flow resistance, no rust, no scale, not easy to plug, efficient transportation.
Anticorrosion
PVC agricultural irrigation pipe has good corrosion resistance and stable performance, and it will not only not be corroded when conveying the water injected into the fertilizer, but also does not destroy the nutrients in the fertilizer to ensure the production needs of crops.
Anti-aging
The PVC agricultural irrigation pipe formula is added with antioxidants and light stabilizers, so that the pipe has excellent anti-aging properties, long-term light or buried can ensure its performance, and the service life is as long as 20 years - to 50 years.
Save Labor
The pipe has stable performance, good health performance, does not affect water quality, and will not cause non-toxic and pollution-free crops.
Easy to install
The pipe has the advantages of light weight, convenient transportation, installation and use.
1. Cost-effective; 2. Integated production line; 3. Advanced integrated equipements; 4. Strict processs control; 5. Presicion Meter weight control system; 6. Self owned CNAS laboratory; 7. Sturdy safe connection
