Supplied Pipe Chain Coupling Pack calculator.
Count supplied joints in separate open chains or already specified closed loops, then round matching couplings to packs.
Your inputs
Use measurements from your plan and properties from your chosen product. Any prefilled values are illustrative.

Formula and assumptions
How this calculation works.
Joints in an open chain = segments − 1; joints in a supplied closed loop = segments. Does not design a network, approve a loop or choose a coupling suitable for a service.
A worked example
Illustrative inputs only. Product properties and design dimensions are not recommendations for your project.
- Matching couplings per pack
- 5
- Your supplied connection topology
- Open chains
- Already specified straight segments
- 4
- Identical chains
- 2
Matching coupling packs: 2 packs
Counts this specified topology only; branches, elbows, tees and equipment connections are not automatically supplied.
Before you purchase
Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.
