Cutting and sawing

Blasting and coating

Before it is made – through bending, end forming,

In an automated blast cycle, a titanium lance travels at consistent speed through the tube, providing even contact and excellent part quality. That evolution in processing also typifies the other two specialities considered here. But unprotected steel surfaces are famously susceptible to corrosion. Hence coating and galvanizing; and, with them, resistance to moisture, oxygen, solvents and a host of other threats to a long and reliable service life for the tubular product or part.

chamfering, drilling, punching, milling – into a product, a tube is known as a blank. And a blank it will remain if it is not cut with caliper precision: clean, straight, to length. If this process is not right, it will matter very little what else is. No amount of subsequent effort will rescue a profile that has been compromised from the first pass of a blade si tube makers know the critical importance of accurate cutting.
