The threaded PVC pipe is a white hard wire pipe that is used for corrosion protection, leakage prevention, and wire threading. It can be used in indoor normal environment and in places with high temperature, dust, vibration and fire hazard. It can also be used in wet places. However, it should not be used in places that are particularly wet, acid, alkali, salt corrosive and explosive. Threaded PVC pipe fittings are used to mechanically connect two sections of plastic pipe. This process is used to accommodate pressures above 100 pounds per square inch (psi).

Step to thread PVC pipe fittings


Step 1

Place the PVC pipe in a vise so that the end is at a threaded distance of 6 to 8 inches from the clamping mechanism. Be sure to pay attention to the distance between them. Only by controlling the distance can you continue the work.


Step 2

Wrap the PVC pipe with a rag to match the clamping mechanism. The rag protects the surface of the plastic. Secure the pipe in the vise and do not overtighten the clamp as this will rupture the pipe. If the pipe breaks, you can't do the rest.


Step 3

Place the tapered rod in the PVC tube. The tapered rod helps keep the center of the manual threading machine and the side walls of the pipe from rupturing prematurely.


Step 4

Slide the threader onto the pipe and then slide it first. The threads should face outwards, away from the tube ends. Don't go wrong, or there will be problems next.


Step 5

Start the thread die with a handwise. Push on the end of the die as you engage the pipe. This hand pressure will begin the threads evenly.


Step 6

Continue to use a long handle to screw into the pipe to rotate the mold. Place the threaded portion of the mold on the PVC pipe. When the back of the mold is aligned with the end of the tube, the threading is stopped.


Step 7

Turn the mold counterclockwise to remove it. After removing the new thread from the vise, wipe it off with a rag. This will be done.


What should I pay attention to when using it?


1. For the pipe line that is darkly applied to the wall, buried in the underground non-combustible body, and the line pipe for ordinary residential houses such as rural buildings, PVC threading with certain flame retardant properties and meeting the requirements of physical and mechanical properties shall be adopted tube.

2. For places with high fire risk, flame retardant PVC threading pipe with higher combustion performance level should be selected.

3. For the fire-fighting distribution line and the automatic circuit of the fire alarm system, it is mandatory to use it that meets the requirements of the Ministry of Public Security.

4. For the renovation of cultural relics, Mingfu electric circuit, indoor decoration and secondary decoration, and the renovation of old and old buildings, it is necessary to use it with burning performance above B1.


In conclusion


Typically, in deep well applications, they are also used, as long distances can create unusual stresses. Only the Schedule 80 and Schedule 120 PVC pipes can be threaded. Schedule 40 PVC pipe wall thickness is too thin. I hope this article can help you.
