The Best Piping Products for Repair, Maintenance and Upgrades 7 December 2017
Sometimes repairs or modifications to the piping system need to be done. This can be years or decades after the initial installation. Sometimes mistakes are made during the initial installation that will prompt a correction or repair.
Regardless of the reason, there are a few product that can really come in handy whenever repair or modifications are being done.
1. The repair socket
The repair socket is used whenever there is need to replace a socket, either because it was found to be leaking or if there was a power outage in the middle of welding. Shit happens, we just need to be able to fix it.
The repair socket looks like any welding socket on the outside. But in this case it is the inside that matters. The repair socket lacks the pipe stop you will find in regular sockets.
Once you have cut out the faulty welding socket, measure up a piece of pipe that will fill the gap. (Make sure the cuts are nice and square first!)
With regular sockets you would need to free long lengths of pipe to be able to fit everything together, but not with the repair socket. Since there are no pipe stops in it, it will slide over the pipe - and then you can slide them into position over the joint.
Just remember to measure and mark the correct position on the pipe, clamp the pipe on either side and verify the socket's position before you weld.
Remember that two repair sockets are needed in order to replace the first welding socket. Always keep 4-6 in the box with extras and spares.
2. The "Anaconda"
This is basically the same thing, a repair socket, but for double wall piping. It takes a bit more work and extra thought before you get started.
For the inner pipe you will do the exact same thing as for the single wall pipe above, but you will need to trim the green outer pipe a bit so that you can fit the black repair sockets on.
Then you are going to encapsulate all of that with two reducers and a 125 mm pipe. Both of the black repair sockets will sit inside of this.
Once mounted on the pipe, it will look sort of like a snake that had a very big lunch. Hence it got the nickname "anaconda".
What is important to remember is to slide these green parts on BEFORE you weld the primary pipe. Otherwise you waste another 30 minutes doing the whole operation all over again... And there is quite a bit of scraping, cleaning, measuring and marking involved here so the best thing is to remember this.
Getting the Anaconda in place may seem like a lot of work, but it is way better than replacing the full pipe run. Always keep 2-4 of the reducers or 1-2 anaconda kits in the van.
3. The mechanical transition fitting
Yes, this is just a regular compression type plastic-to-steel transition fitting. But it can come in very handy when doing repairs and upgrades at a site that has been in operation. At these sites, there is always a risk that vapors are present, and you must not do electrofusion welding in areas where there is a risk of flammable atmosphere.
In these cases, there are two options: Either ventilate or purge with nitrogen to remove any vapors before welding - or use the KP C14 transition fitting which can be installed using wrenches. This fitting requires no electrofusion welding so you will not have to worry about the presence of vapors.
And that was our top solutions for repair and maintenance. Stock up and be prepared!
