Lining 5 90°s | Tech Tip Tuesday
Hi! Welcome to Tech Tip Tuesday!
Today we're going to do a little shot here with Houseliner. So this is a 63 to 100 (3"-4") liner. We're going to shoot through a bunch of 4”. So we have five 90s in 4” that we're going to shoot through. I think I count them right. 1-2-3-4-5. Nailed it. So, we're going to be using a tail. We've talked a little bit about this recently.
You guys will see kind of how this navigates. We're not going to shoot cal tube through it. We have a, kind of a tearaway tail on the end of this one. So something we glue on there, it allows the liner to inflate itself. This is, really flexible Houseliner - there's actually one even more flexible that we could do even better bends with - but, it's probably the most common one that we use as the FL series 3-millimeter thick. It's a really, really good transitional and flexible liner. So we're going to get started. So we've got some, small kits that we're going to do with this. just to kind of keep our waste to a minimum here. So we're going to mix it on a slow speed a couple minutes here.
[Bonus Tip: Mixing on low speed from the bottom up, without breaching the surface, reduces the amount of air in your resin.]
We're going to vacuum the liner down here and make sure we get all the air out of the line.
So we're going to wet this guy out at 6.5mm thick.
[Bonus Tip: Use an ice bath or cool water to extend your resin working time!
Put that down in there to let it cool off. Just for a second. It's not necessary. Ice water. It's just like cold water.
[Bonus Tip: Put mineral oil on the surface of your ice bath. This lubricates the liner as it comes out of the water and into your inversion device!]
Just put a little oil in the water. So, as it comes through the top, it'll get some oil on it. We're going to tie this in here.
So one thing - I've got the letters up on the liner, so I'm going to keep it that way. So when I get this set, it still has to remain letters up.
[Side Note: Here comes the tail! Look at how cleanly it inverts past the liner, ensuring a smooth transition back to the original pipe.]
(Four hours later.)
All right, so the liner is cured. We're gonna go in and pull the tail off. So, like I said, I've got a pull rope all the way through here attached to that tail on the end of it. So I'm going to do is I want to drop the pressure in that tank in and reel back on that and it should just pull right back out of the liner and then reel back into the tank. So, drop our pressure here.All right. Now, this is easier below ground because the pipe doesn't move. But we can make it work. Well, there it goes. So, tails off and reeling back towards me, and there it is in the tank. So that's all the material used, guy That ripped off the liner at the end, and all we got to do is reel that back in through, - no struggling to get the cal tube out or anything like that.
All right - so there's the end of the liner and it's where our tail would go.
There is 90° number 5. 4. 3. Hang on, 2 (0 wrinkles), and 90° number 1 (zero wrinkles)!
There you go, so that's what using tails, using Houseliner or Brawoliner materials. This one's a Houseliner. 3” to 4” transitional. So if you use a 3” to 4” size in 4.” It inverts easier in the bends and looks amazing. So, around these will have very minimal wrinkling, and then it's just 1-step version.
You rarely, if ever, have any kind of issue with actually going in, because it's so much easier in cal tube. So, we can do a one-step inversion. This guy will be cured in, like, four hours. So, yeah, one-man shot, makes it really easy. You don't have to mess around with moving anything over or anything like that.
It's just, you load it, you have control of the liner the entire time because we've tied the knot on the tail into a drum so I can go back and do stuff like that whereas opposed if you're doing a two-step liner and then cal tube shot, you have to, once you got like halfway out, the liner just inverts.You don't really have that much control over. It's just air pressure. But this, I have full control of the liner the whole way around, and it's just a one-step, and it's just going to look so much better than the cal tube shot. So. Yeah. There you go. House liner with tails - and you can learn it here at APS.
