Technical FAQs
Q: Can a single machine produce multiple oval sizes?
A: While each size requires specific tooling, our modular design allows quick changeovers by swapping roller frames while reusing core components.
Q: How does interlocking differ from welding?
A: Interlocking mechanically folds seams for materials ≤1.2mm, while welding (TIG/laser/HF) is used for thicker materials requiring fusion joining.
Q: What are tube connection methods?
A: Our systems can create necked ends with ribbing for secure push-fit connections between pipes.
