Hello, everyone.
This is Enta.
One piece of information we need is the hose diameter.
It's definitely useful to know this.
Please be sure to keep this in mind.
| Name | 1 minute | 2 minutes | 3 minutes | 4 minutes | 6 minutes | inches | 1/4 inch | one and a half inches | 2 inches |
| mm notation | 3 | 6 | 9 | 12 | 18 | 25 | 32 | 38 | 50 |
| Inch notation | 1/8 | 1/4 | 3/8 | 1/2 | 3/4 | 1 | 1 1/4 | 1 1/2 | 2 |
I think slope construction and earthwork contractors generally use the same notation.
Since it's just the nominal diameter, it's not very accurate.
Just keep in mind that if you multiply 1 minute or 2 minutes by 3, you'll get a rough measurement in millimeters.
For example, if you tell a contractor, “I measured the inner diameter of the hose, and it’s about 5.5 mm,” they’ll say, “That’s a 2-minute size, isn’t it?”
For slope work, the standard sizes typically used are 6-bun, inch, and 2 inches.
The spray hose has a slightly unusual diameter of 48 mm, lol.
If you're an anchor installer, you'll almost always need at least two minutes because of the hydraulic hoses.
I don't really use the 1-minute setting very often. I guess I might use it for something like injecting medication or something like that.
As contractors, we can usually tell just by looking, so asking another contractor is one way to make a decision, but if you know the answer yourself, you can respond immediately.
This is good information to know.
However, please note that the names of steel pipes and similar items may vary slightly.
See you later.
