PVC pipe nipple refers to the joint part of PVC pipe fittings, which is used to connect PVC pipes. Its main component is polyvinyl chloride (PVC), and other components may be added during the production process to enhance its heat resistance, toughness, ductility, etc.
In actual applications, when connecting PVC pipe fittings, you first need to use sandpaper to roughen the outside of the PVC pipe end and the inside of the PVC pipe nipple socket, then use a clean rag to wipe off the sanded hair, then evenly apply glue, and finally insert the pipe end into the socket of the fitting. This process requires the use of appropriate glue, and avoiding using inferior or expired glue to avoid potential hazards such as leakage.
PVC pipe nipple types
PVC pipe fittings are of various types, mainly including straight joints, elbows, tees, crosses, five-ways, six-ways, reducers, and flexible joints.
1. The straight joint is used to connect two PVC pipes in a straight line. Common specifications include 20, 25, 32, 40, 50, 63, 75, 90, 110, 125, etc., suitable for various purposes such as water supply and drainage.
2. The elbow is used to change the direction of the pipe, including PVC 45 Degree Elbow and PVC 90 Degree Elbow. The latter is commonly used in plumbing installation and is used for connection at the end of the pipe. It connects two pipes with the same or different nominal diameters to make the pipe turn 90° and various degrees.
3. Tees and crosses are used to branch a pipe into two or three pipes, suitable for occasions where multiple directions need to be connected at the same time.
4. Reducing joints are used to connect pipes of different diameters to achieve diameter conversion.
5. The flexible joint is easy to disassemble and assemble, suitable for occasions that require frequent disassembly and maintenance.
In addition, PVC pipe nipples also include other types of connectors, such as pipe clamps, flanges, threaded connections, etc., to meet different connection needs. These pipe fittings are widely used in many fields such as building internal and external water supply projects, industrial and mining enterprise water supply projects, and underground fire protection water supply projects. They are favored for their safety, durability, sustainability, and recyclability.
Advantages
1. Strong corrosion resistance: PVC pipe nipple has extremely strong chemical stability, can withstand strong acids and alkalis, does not rust and scale, and has no secondary pollution. , so that it can maintain good performance in a variety of environments.
2. Low fluid resistance: Its inner wall is very smooth, the surface roughness coefficient is low, the fluid resistance is small, and the water pressure will not be excessively reduced, effectively improving the water delivery capacity. This feature enables PVC pipe nipples to maintain a high efficiency when conveying fluids.
3. High mechanical strength: The joint has good water pressure resistance, impact resistance, and tensile strength, ensuring its safety in high-pressure and dynamic environments.
4. Light texture and easy installation and construction: It has low density, is easy to carry and load, and uses special adhesive bonding or elastic sealing sleeves to make installation and construction simple and quick.
5. Long service life: Under normal use conditions, the effective service life of PVC pipe nipples is more than 50 years, with good aging resistance and chemical resistance.
