3 Tips For Optimal Pneumatic Tool Performance


Pneumatic tools are utilized in a variety of tube tool applications from expansion to cleaning. While the power source is often determined based on operator preference, there are some applications where air may be required or preferred over electric. However, to get the best life and performance out of pneumatic tooling, it’s important that the quality of air and the amount used is regulated correctly.

Choosing The Right Rolling Motor


With a wide variety of rolling motors on the market, choosing the right one can seem overwhelming. There are several factors to consider when selecting a rolling motor. Power source, torque control, RPM, torque range, and the style of the motor will vary depending on the application.

How To Expand Welded Tubes


Expanding tubes after they have been welded can be frustrating for operators. If not rolled properly, tube material can build up and put stress on the weld. In extreme cases the tube material can build up so much that the expander can get stuck in the tube, delaying the job.

How to calculate roll ID


Tube Expanding is based on engineering principles, involving elasticity and plasticity, to compress the OD of the tube against a fixed container, such as rolling tubes into tube sheets, drums, ferrules or flanges. To assure a proper tube joint, the tube wall must be reduced by a predetermined percentage. The following chart can be used for determining the correct tube wall reduction.

Expanding Tubes In Heat Exchangers


Before you can start rolling, you will need to select the right expander for the job. Tube OD, and Wall/BWG will determine the size of the expander. However, there are some other factors to consider, such as tube projection, roll length, reach requirements, space constraints, and whether it’s minimum or average wall tubing.

Expanding Fire Tube Boiler Tubes


Firetube boiler tubes consist of an expanded and beaded tube end. The method for achieving a bead has advanced over the years to include both hand beading and single roll beading expanders. In order to ensure a proper bead, there are several steps that need to take place before expansion can occur.
