Determining Proper Wall Reduction With Tube Material

Knowing how to determine wall reduction is important; however it is equally important to know the characteristics of the popular tubing materials. A simple rule of thumb is the harder the material, the less wall reduction required to obtain a tube joint.

Minimum Vs Average Wall Tubes & Why It Matters

Getting the right tools for your application is critical in order to complete the job right the first time. One of the most overlooked factors when ordering tooling, is determining whether you have minimum wall or average wall tubing.

Best Practices For Expanding Water-Tube Boiler Tubes

The American Society Of Mechanical Engineers (ASME) develops standards to provide consistency and ensure public safety and reliability. While these codes are not always required, they have been widely adopted and implemented across many industries. As a result, it is important to be knowledgeable and aware of these standards prior to beginning a job.
