<\/p>\nHello, everyone.<\/p>\n
This is Enta.<\/p>\n
<\/p>\n
In dewatering drilling operations, after drilling the borehole, you insert a strainer pipe and then pull out the outer casing, right?<\/p>\n
At that point, it all falls together (the inserted strainer tube falls along with it), right?<\/p>\n
<\/p>\n
What do you do in situations like that?<\/p>\n

<\/p>\n
I think I introduced something like this a while back.<\/p>\n
<\/p>\n
It's nice to say things like this, too.<\/p>\n
But, to be honest, it doesn't really matter much considering the price\u2014it just slips out, lol.<\/p>\n
They'll both go down together.<\/p>\n
Every time I remove the casing.<\/p>\n
<\/p>\n
I'll teach you my trick, lol.<\/p>\n
It's quite effective on PVC.<\/p>\n
Since SGP pipes (gas pipes) are heavy, please use plenty of them!<\/p>\n
You're probably thinking, \"What?\" right?<\/p>\n

<\/p>\n
It looks something like this.<\/p>\n
For PVC, just attach it halfway around in two or three places, and you're good to go.<\/p>\n
<\/p>\n
As the saying goesEptsealer<\/span><\/strong><\/span>That's it.<\/p>\n If you wrap this around it halfway, it won't fall off.<\/p>\n Simply put, it increases circumferential friction resistance!<\/p>\n It's fine to wrap it around once.<\/p>\n <\/p>\n If you wrap it around too many sections, it will be a little harder to slide it on.<\/p>\n And if you put too much in, it gets hard to take out lol<\/p>\n Connect the PVC pipes, and apply the Eptosealer while they are in this position.<\/p>\n Most of them have an adhesive backing, so they'll stick firmly, but if there's grease or mud on them, please wipe it off.<\/p>\n Then just stick it somewhere convenient, and you're all set.<\/p>\n <\/p>\n This is for when the SGP is active, and since weight is applied when the angle is 5 degrees or more,<\/p>\n If you increase the friction\u2014for example, by applying Eptsealer tape in several places along the length\u2014it will become much harder to pull out.<\/p>\n It does make the inside of the casing a little heavier, but it still slides in easily.<\/p>\n <\/p>\n Maybe we don't need that anti-slip mechanism at the tip anymore? lol<\/p>\n If you want to keep costs down, this is the best trick!<\/p>\n <\/p>\n See you later.<\/p>","protected":false},"excerpt":{"rendered":" Hello, everyone.
