Parallel vs. Tapered Roll Expansion: Impact on Stress Corrosion Risk

2025-06-30T08:13:05-05:00

Stress corrosion cracking is a common tube failure mode in corrosive environments, which can lead to significant downtime and cost. While there are many different factors that can influence the occurrence of stress corrosion, it’s largely related to the amount of stress the tube material is under during fabrication and operation. Optimizing the manufacturing process to minimize residual stress can help reduce the likelihood of stress corrosion cracking from occurring.

3 Tips For Optimal Pneumatic Tool Performance

2023-02-02T10:45:09-05:00

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.
