The range, and the bores the examples use
The published layflat range of this manufacturer runs from 3/4 in to 16 in inside diameter, in standard rolls of 30 m to 100 m, across a published working-pressure range of 2 to 10 bar for the family as a whole — the rating at your bore is confirmed in the quotation. The worked examples in this guide are built on four bores — 2, 3, 4 and 6 in — and the table below sets example roles against them: roles to test against your own pump curve and ground, not a statement of what any size is typically bought for. The handling notes are worked assumptions on the same basis: crew numbers are figures to check against the delivered roll, not measured facts, and the roll weight for your order is one of the figures the quotation confirms.
| Size | Example roles | Handling — worked assumptions |
|---|---|---|
| 2 in | Small pumps, farm and site dewatering, sprinkler supply | Light rolls; worked here as one-person handling |
| 3 in | General construction dewatering, irrigation mains on small farms | Mid-weight rolls; worked here as one person for short rolls, two when wet |
| 4 in | Main irrigation lines, municipal drainage, larger dewatering | Standard rolls 30 m or 50 m; worked here as two-person handling when wet |
| 6 in | High-volume transfer, flood and bypass pumping | Heavy rolls; plan mechanical handling and larger couplings |
| 8 in and above | Industrial and municipal trunk lines, mining water | Quoted per project; coupling and reel planning essential |
The three-way trade every size decision makes
Bore, pressure and handling pull against each other. The published range is a family figure, not a rating for your size, so the class confirmed at your bore in the quotation is the only figure to order against; a buyer who needs both a big bore and a high pressure should expect a heavier construction class and say so plainly in the enquiry, rather than shopping the headline numbers of two different sizes. Roll length is the third leg: the published rolls run from 30 m to 100 m, and the company's FAQ notes the usual roll lengths as 30 m or 50 m.
Sizing mistakes
- Sizing to the pump outlet alone: the coupling for an order is confirmed in the quotation against the outlet and the hose tail it has to join, and the run length belongs in the bore choice too.
- Reading the range backwards: '2 to 10 bar' describes the family across all sizes, not every size; confirm the class at your bore in the quotation.
- Forgetting the suction side: a layflat size plan that ignores the corrugated-wall suction hose feeding the pump is half a plan — the two are sized together.
- Ignoring coupling availability: include the camlock and flange hardware in the enquiry from the start.
Worked examples, stated as examples: a farm irrigation main that will be moved twice a season is worked on 4 in in 50 m rolls; a hire-fleet example is worked on 2 in and 3 in, the bores whose rolls the worked handling notes above treat as one-person work; a flood-response stockpile is worked as a 6 in layflat kit with matched suction hose and camlocks. None of these is a claim about what farms or fleets usually buy — they are worked examples — and share your pump curve and run length with the enquiry and ask for the examples to be tested against them in the quotation.
Which layflat sizes are the common ones?
The sizes this guide treats in depth are 2, 3, 4 and 6 in — the bores around which the worked examples and role notes in this guide are built. This manufacturer's range covers those sizes and far beyond them, to 16 in.
Can I order mixed sizes in one shipment?
Yes — mixed sizes can be quoted as one programme. List each size with its pressure class and metres; the quotation prices each line; ask for the packing to keep sizes separated by roll marking.
Does a bigger bore always move more water?
Only if the pump can feed it. Flow is set by the pump curve against the system. Match bore to pump and run length together.
Request a Quotation
Send the hose family, bore size, working pressure, length per roll and total quantity. MOQ, packing and lead time are confirmed in the written quotation for your exact specification. If the hose will be supplied as a finished assembly, name the coupling standard you need (for example camlock type and size, flange or thread) — or state that you need bare hose only.
