Glued PVC pipes

[BjörnBygger]

Why aren't glued PVC pipes (usually UPVC) used in Sweden?

Used in many countries. Usually have a blue color. Costs a fraction of other materials (PEX, PEM, etc) and can be glued together quickly and securely.

Not the same lifespan as PEM? Can't handle our climate?

The Tangit adhesive used for bonding sampling detector pipes (fire alarms) has a very strong smell, so a protective mask (for breathing & eyes) and protective gloves are needed during use. The smell lingers for several hours, so respiratory protection is needed for a long time if it is in an "enclosed" property.

They don't have a protective casing, which is more or less a requirement for us today with our wooden houses filled with insulation. Then there's the labor cost, which is the biggest part when laying pipes, and it is faster to lay a flexible tube without joints than to piece together hard pipe parts. The glue and the occupational safety regulations around it also increase the cost.

The glue and the occupational safety regulations around it also drive up the cost.

Thank you, useless. It should be possible to have protective pipes of the same material, right? The glue usually contains butanone, tetrahydrofuran, and acetone, all of which are relatively harmless if you just have good ventilation. In the third world, they apply the glue directly with an unprotected finger.

I agree, PEX and PEM are much easier to install. They would have been my absolute favorites if they could be glued like UPVC. Sooner or later, there's always a connection that starts leaking.

Should we start burning coal & oil?
Should we start medicating animals, that we raise, preventively with antibiotics & all other medicines that maaaaybe would be needed?

Or should we remove all airbags, seat belts, etc., that are meant to protect the user?

I know, it sounds completely crazy to us Swedes, but in other countries, they have something called personal responsibility. They inform themselves about the risks and decide for themselves if they want to expose themselves to them. No one forces anyone to use PVC glue, there are many alternatives. But those who want to use PVC glue do so.

then it is very much that Sweden is the best and everyone else is worse........why do like everyone else when we can do it in a different way that we then think is better and at the same time think that others are doing it wrong.

How do you solve this with PVC seamless.

In what way should this be a disadvantage?

then there's the aspect that Sweden is the best and everyone else is worse........why do like everyone else when we can do it differently, which we then think is better and at the same time we think others are doing it wrong.

The conditions differ quite significantly from other countries.
- Partly, we build a lot with wood and have a lot of insulation, which means that any leaks have entirely different consequences than in stone houses in southern countries.
- We have better workplace regulations than the 'third world,' which makes it difficult, for example, to use glue with strong solvents on a construction site.
- Labor costs are relatively high in relation to material costs compared to many other countries, which often makes it cheaper to use more expensive materials that are quicker to install.

It's not possible to run without joints, as far as I know. But since the joints are glued, they are much safer than, for example, a regular PEX joint. The glue dissolves the PVC, so in practice, the pipes are welded together. However, more pipe bends are needed because the pipes are not very flexible.

Sure, the conditions are different, but in many ways, it's just as I wrote. There are plenty of good solutions for, for example, shower drains that don't even exist here. No, here we insist on using loose drains and compression rings and sealing layers that fail, and God knows what else. Because we know best, of course. When I worked at Arlanda before, they always procured completely custom fire trucks, from scratch, everything was built for the client. From electronics to everything, basically. Even though there are manufacturers that make fire trucks for the rest of the world's airports that work excellently and have available spare parts, it doesn't matter. We know best.

No, here we stubbornly stick with loose floor drains and sealing rings and membranes that come off, and who knows what else. Because we know best.
When I used to work at Arlanda, they always procured completely custom fire trucks, from scratch, everything was built for the client. From electronics to everything, basically. Even though there are manufacturers that make fire trucks for the rest of the world's airports that work perfectly fine and have spare parts available, it didn't matter. We are the best.

Agree. There is a lot to learn from other countries. Used this hoe frequently when I lived in Asia. For many jobs, it is far superior to a spade. It's found everywhere in the third world, but can't be bought in Sweden.

Many years ago, sewage pipes were glued here in Sweden, and the glue affected the pipes so they tend to crack. The blue pipes might have a better plastic blend.

The pickaxes look like a small trenching tool with a long handle, so something similar exists here. A planting pickaxe could be an alternative.

It's probably not superior to a spade in Swedish clay soil...

 

[prototypen]

There is also fine soil in Sweden.
