Tube vs Pipe – The Differences

Even looking on the internet can lead to confusion, as many websites have mistakenly misidentified the real differences between them. Well, since I’m a know-it-all, let me try and explain as best I can what exactly differentiates tube and pipe. There’s a nifty looking infographic you can share at the bottom. Tubing Tubing is generally used for structural purposes and the OD is an important and…

How To Use A Tubing Bender

A tubing bender is a relatively simple tool to provide accurate and consistent bends on a variety of tubes including copper tubes, steel tubes and aluminum based tubes. While there are numerous automated tube benders available that are electrically and hydraulically powered, these machines can be bulky and not suitable for on site applications that may not have access to appropriate power…

Pipe and Tube Cutters Information

Pipe and tube cutters are hand-held tools or machines that use a rotating cutting wheel, blade, or other tool head to separate a long piece of tubular material into two or more parts. Pipe and tube cutters can be manually, electrically, pneumatically, or hydraulically powered. The type of cutter used depends on the material, diameter, and thickness of the pipe or tube. Pipe and tube cutters are…

Temperature and pressure decide which type of tube fitting is needed. Metal fittings are used for high temperature and pressures, plastic fittings for low. Typically, metal fittings are used with metal tubes, but plastic fittings are sometimes used with metal tubes to reduce galvanic corrosion. The fittings used on hydraulic tubing for high-pressure applications are categorized as either…
