Van Stone Flanged Ends
This process mechanically flares the steel pipe to form a tafted end, a rotating flange is mounted behind this. We can supply standard pipe spool with 2 Van Stone flanged ends, offering considerable cost savings over welded pipe spools and allowing easy alignment of spools on site. Stainless steel pipe spools in particular can be very cost effective with this construction method.

Welded Construction Pipe Spools
Pipe spools are manufactured typically with a welded flange at one end and a loose slip on weld flange behind a welded stub end / taft ring allowing pipe spool alignment on site. We are also asked to supply pipe spools with fixed / fixed flanges or both rotating.

Threaded Construction
With this type of pipe spool the pipe is threaded and a threaded and hubbed flange is screwed home on the pipe forming a mechanically sound flanged end. With the flanges being threaded slight misalignments on site can be fixed by rotating the threaded flange.
