LUBONYL PVC AVL Rör - fråga om datum

[MultiMan]

Can always start calling around for quotes, but if it's not cast iron, I'm satisfied.

Cast iron held/holds much better than eggshell pipes, but I think it was the opposite there. In the end, cast iron pipes became thinner and worse, while earlier versions were thicker and lasted longer. 🤓 I'm following a drainage channel in the USA (the guy above is in Sydney, Australia) and there are still plenty of cast iron pipes there.

Cast iron held/holds much better than the egg shell pipes. 🤓 Follows a sewer channel in the USA and there are still plenty of cast iron pipes there.

I read a bit more and googled further about egg shell. Found out that thickness and standard: The pipe follows the standard ⁠SIS 326⁠, which means that it is an approved, normal-walled sewer pipe designed to withstand ground pressure. Egg shell pipes are most often associated with thinner, gray or white pipes from the 60s that lacked this material stability.

So this is hopefully a later version?

There are still plenty of old cast iron pipes here as well. Some are in excellent condition and will last a few more decades, while others gave up decades ago... I suspect it depends on differences in what is flushed down the water and slight differences in the composition of the cast iron, this in combination.

Cast iron pipes are still installed in some cases due to fire protection requirements, but don't ask me about the details.

To my knowledge, there are no "later versions." They were used for 5-6 years or something similar and then pipes that hold in darker gray color or orange were used, which we still use without problems.

If you ask AI, you shouldn't trust everything you read, much of it is wrong.

Yes, the eggshell pipes were, of course, approved when they were installed. At that time, the problems were not yet known. PVC is a fantastic material if manufactured correctly.

Photograph the pipes to see if there are any problems. It doesn't cost much.

As I wrote, Lubonyl was bought out in the early 1980s, so your pipes are from the construction year.

I seem to remember that we have lubonyl in the house, I dug up a stretch to adjust a back slope. Held for the scoop until I reached a joint, then it cracked when I grabbed it.
So I don't think they were so weak, have a few meters hanging on the wall in the basement as well. Haven't sprung a leak.

Just like cast iron, it may vary between different installations, but I still think a camera inspection could be worth the money.

There are still plenty of old cast iron pipes here too. Some in excellent condition and will last a couple of decades more, some gave up decades ago... I suspect it depends on differences in what is flushed down and detail differences in the content of the cast iron, this in combination.

Okay, then it was completely wrong. Someone is going to come and check it but should I be worried or concerned? Everything flushes well, no blockage, the water moves well.
