Kaiflex - a cut above
The first cut may be the deepest but just where should you make it? Kaimann publishes a comprehensive application guide that covers all of the key skills and techniques needed to install the material on just about any piece of pipework or equipment.
Aimed at professional insulation contractors, the Kaiflex Application Guide is an invaluable tool for anyone looking to install Kaiflex. In practice, however, most installers of Kaiflex need far less information and the most frequently asked questions about how to install Kaiflex are actually the simplest ones. Making these answers available outside the Kaiflex Application Guide is something that we’re very keen to do.
Around the bend
Perhaps the most commonly asked question about how to install Kaiflex is how to insulate a bend using Kaiflex tube.
For air-conditioning contractors working with flexible Copper pipe coils this is a very straight-forward question. Provided the tube is sleeved on (always pushed on, never pulled!) the Kaiflex should be more flexible than the pipe itself and the nature of the pipe means that 90° bends are never too tight.
When tighter 90° bends are a part of the project you may still, depending on the pipe diameter and insulation thickness, find that Kaiflex is still flexible enough to push around the bend but this will often be either impossible or undesirable.
Angling for the right approach
In such situations the only way forward is to cut the tube at an angle to create a fitting that matches the pull of the bend but without any of the tension. Cutting Kaiflex is easy – any sharp flat bladed knife will do the trick. We’d always recommend keeping a sharpening tool nearby to keep the blade as sharp as possible.
Another tool that’s pretty invaluable is a cutting chart with the most common cutting angles marked on.
A cutting chart is something that we're always keen to provide to customers. It's really a fundamental tool which is why we offer it as a free download from our website. Just download the PDF below and print out as many copies as you'd like.
