Frequently Asked Questions (FAQ)
Q1: What is the difference between spiral welded and seam welded filter tubes?
A: Spiral welded tubes are formed by continuously winding a wedge wire in a spiral pattern and welding the intersections. This creates a stronger, more uniform structure compared to seam welded tubes, with better resistance to deformation under pressure and backwash cycles.
