How do you measure a lay flat hose?

Decoding Lay Flat Hoses: A Simple Guide to Getting the Right Size

Lay flat hoses. You see them everywhere, right? From farms to construction sites, even battling wildfires. Their superpower? They fold flat when you’re not using them, making them a breeze to store and haul around, unlike those rigid, clunky hoses. But here’s the thing: figuring out their size can be a bit of a head-scratcher.

Now, most folks make the mistake of just measuring across when the hose is flat. Nope! The real key is the inner diameter (ID). Think of it like this: the ID is the width of the pipe that the liquid flows through. This measurement, usually in inches or millimeters, tells you how much liquid the hose can actually handle. Getting this right is super important, because you want everything to fit together properly – pumps, connectors, the whole shebang.

So, how do you actually measure one of these things? Let’s break it down:

Converting Flat Width to Inner Diameter: A Mini-Cheat Sheet

Okay, grab your measuring tape. Lay the hose flat, nice and smooth. Measure from one edge to the other. Got it? Now, find your measurement on this list to get the I.D.

• A width of about 65mm? That’s roughly a 38mm I.D.
• Around 85mm wide? You’re looking at a 50mm I.D.
• Spot on 125mm? That converts to a 75mm I.D.
• Stretching to 175mm? You’ve got a 100mm I.D. hose.
• A hefty 250mm across? That’s a 150mm I.D.
• A whopping 325mm? You’re dealing with a 200mm I.D. hose.

Now, a word of caution: these are just guidelines. Depending on the hose – what it’s made of, how thick the walls are – these numbers can wiggle a bit. Always, always double-check before you buy fittings. Trust me, it’ll save you a headache later.

More Than Just Size: What Else Matters?

Picking the right lay flat hose is more than just getting the diameter right. Here’s what else you need to think about:

• What’s it made of? PVC, rubber, polyurethane… they all have different strengths. Make sure the material can handle whatever you’re pumping through it, and that it can stand up to the weather.
• Pressure, pressure, pressure! Can the hose handle the pressure you’re throwing at it? Check the pressure ratings – both the normal working pressure and the “burst” pressure (the point where it goes kaboom!).
• What are you using it for? A tiny hose won’t cut it for a huge job. Two-inch hoses are great for gardens and smaller firefighting tasks. But if you’re dealing with a mine, a construction site, or a flood, you’ll want something bigger – three, four inches, or even more.

Common Sizes: A Quick Rundown

You’ll find lay flat hoses in all sorts of sizes, but here are some of the usual suspects:

• 2 inches
• 3 inches
• 4 inches
• 5 inches
• 6 inches
• 8 inches
• 10 inches
• 12 inches

The right size really depends on how much water you need to move, how far you need to move it, and how much pressure you’re working with.

One Last Thing: Burst Pressure Isn’t Always What You Think

Here’s a fun fact: bigger isn’t always stronger. Just because a hose is wider doesn’t mean it can handle more pressure. In fact, sometimes the smaller hoses can take more of a beating! It all comes down to the material, how thick the walls are, and how it was made.

Wrapping It Up

So, there you have it. Measuring a lay flat hose isn’t rocket science, but getting it right makes a huge difference. Nail that inner diameter, consider the other factors, and you’ll be well on your way to smooth, reliable operations. Whether you’re irrigating crops, draining a construction site, or moving fluids in an industrial setting, the right hose will make your life a whole lot easier.
