Does your home use PVC pipes? How much do you know about PVC pipes fittings? Today we are going to introduce you to the outer diameter of PVC pipe fittings.
The PVC pipe drainage pipe is made of PVC resin as the main raw material, adding a proper amount of stabilizer, lubricant, filling agent, color adding agent and so on by plastic extruder extrusion molding and injection molding machine. Through cooling, curing, setting, inspection, packaging and other processes to complete the production of pipe and pipe.
Common specifications of PVC pipe fittings
The usual specifications of PVC pipe drainage pipe are as follows:
The nominal diameter of the pipe is: 32mm, 40mm, 50mm, 75mm, 90mm, 110mm, 125mm, 160mm, 180mm,200mm, 250mm.
Dimensions are in inches unless otherwise stated. For the correct pipe and fitting connections, always use pipes and fittings with the same nominal pipe size. Keep in mind that although all PVC fittings of nominal pipe size are matched with PVC pipe of nominal pipe size, not all accessory manufacturers use the same mold, so some sizes may vary slightly, so you are choosing Be sure to measure accurately when using accessories.
Advantages of PVC pipes fittings
1. Aging resistance is good, normal service life can reach more than 50 years.
2. The surface hardness and tensile strength of the pipe are excellent, and the safety coefficient of the pipeline is high.
3. The linear expansion coefficient of the pipeline is small, 0.07mm/C, and the deformation is small under the influence of temperature. The thermal conductivity and elastic modulus of the cast iron drain pipe are smaller than those of cast iron drain pipes.
4. The pipeline has excellent corrosion resistance to inorganic acids, alkalis and salts, and is suitable for industrial sewage discharge and transportation.
5. Has good water tightness: the installation of PVC-U pipes, regardless of whether they are bonded or rubber rings, have good watertightness.
6. The connection of pipes and fittings can be made by bonding, the construction method is simple, the operation is convenient, and the installation efficiency is high.
7. The friction coefficient of the pipeline is small, the flow is smooth, it is not easy to plug, and the maintenance workload is low.
The above is the description of the outer diameter of the PVC pipe fittings. I hope that you can solve your doubts. If you still don't understand the place, you can consult the official website at any time. We look forward to your reply.
