Polythene Layflat Tubing Video Transcript
Layflat tubing is an endless and seamless tube of polythene in exactly the state it comes from the extrusion machine. I’m going to explain how we measure the tubing and how to choose the right size layflat for your needs. I’ll be using the example of 4” layflat but it comes in many different sizes.
4 inches is the width of the tubing when its laid out flat. In other words, it is half the circumference of the tube. This width is the measurement you will find on our website and in our catalogue. The diameter of the tubing (so the distance across the circular) is not therefore 4 inches and would not fit 4” diameter tubing inside. To fit over a pipe with a 4-inch diameter, the layflat circumference must be calculated. Let me show you how to do it. Take the diameter of your pipe – 4 inches, and multiply it by 3.142 (commonly known as Pi). This is the circumference of the tubing. And it comes to 12.568 inches. To get the layflat width you need to half this measurement. This comes to 6.284 inches. So, to fit a 4-inch diameter pipe inside layflat you will need layflat with a 6.248-inch width. The nearest size we stock is 7 inches. A nice fit, with a little space. Next comes the duty.
Polythene layflat tubing comes in 3 duties. Medium duty, Heavy Duty and Ultra Heavy Duty. Here are two examples to help you decide on the duty you need. Firstly - which duty would you need to hold steel angle iron? For this the medium duty wouldn’t be heavy enough. Heavy duty would be fine with limited handling, but we’d recommend Ultra Heavy Duty if you are going to dispatch with an outside carrier. How about curtains? Medium duty would suffice to hold curtains but not for shipping by carriers. For that we’d recommend Heavy Duty.
