Question: How many field joints are in a mile?
Question: How do I know how many shrink sleeves I'm going to need for my project?
Answer: They don't get very much simpler than this! In our world; pipe is almost always sold in lengths very close to 40 feet. Based on that, all we need is a calculator, pen and paper, or my favorite - and abacus to figure it out.
So, you've got 5 miles of pipe.
1 mile equals 5,280 feet.
Every 40 feet is a field joint.
You will have 132 field joints per mile of pipe.
5 x 132 = 660 sleeves will be needed
(this does not include any overage allowance).
Or, you've got a 1200 foot directional drill.
1200 / 40 = 30 DIRAX sleeves will be needed.
Or, you've got 57 miles of 24" pipe
57 x 132 = 7,524 sleeves will be needed.
