How HDPE Pipe is Assembled and Installed

We have discussed the different types of HDPE Pipe Fittings from the first two posts. We define what  an HDPE Pipe is and the several types of it that are mostly used in the piping industry. While the third post talks about how the lack of piping system affects the Agriculture in the Philippines.

But today, we will talk about the assembly and installation of HDPE Pipes through this video that I found from YouTube. This is shared by the user “adsancorpipe” and is entitled as “HDPE Pipe Installation Video – HDPE Pipe Assembly”. The video was uploaded back in June 28, 2010. It is described as an Innovative Drainage and Water Conservation Solutions using the Corrugated HDPE Pipes.


We learn from this video that it is very important to join the pipes properly to maintain high level of performance that the pipe is designed to provide.

The Assembly of the pipe is showed in step by step procedure.

  •  It should be lowered to the trench. Two workers should be enough to handle an 18-inch or smaller pipes. Larger pipes are lowered using nylon straps.
  • Once the pipes are lowered to the trench, the pipes should be cleansed to remove foreign matter.
  • Apply an approved lubricant on the bell and spigot of the gasket so that it can be aligned properly.
  • After the pipes are aligned properly, it can now be assembled.

The method of assembly is demonstrated by the video and other installation process and tips on how the job can easily be done. But there are major things to inspect the alignment and assembly of the joints.

  • Improper Alignment
  •  Foreign Material Infiltration
  • Rolled Gasket

Failure to correct any of those will compromise the joint integrity of the pipes.

Shortening and fabricating of pipes are also discussed. Scenarios like that also happen on the site of installation. But a tip is demonstrated to easily fix them and ensure the proper joining of pipes. A cut & joint kit is needed to accomplish that.

Workers are reminded that the:

“Writing on the gasket should be facing up and out toward the end of the pipe. It is important that the gasket is seated properly.”

And we are warned that the failure to do it properly will once again compromise the joint integrity.

Another tip is using a homing mark and measurement of the mark on the bell to make sure that the assembly is fitted properly.

That’s it folks! Thank you for dropping by, I hope you enjoyed our pipeful discussion. J
