Detailed Information

What it does

Heat exchanger headers, coils and condenser tubes often need the end closed before drilling and brazing branch tubes. A welded end cap risks leaks and heat distortion; TD-31050 cold-spins the end into a dome in one piece with the tube, and covers larger diameters (above Ø40) that the TD-31040 cannot.

Why cold spinning

One piece, no weld seam, fewer leak paths
No heat, no oxide scale: ready for welding and machining
Stainless tube does not discolor or anneal

FAQ

Copper and stainless?
Steel, stainless, copper and aluminium tubes can be closed if the material is ductile enough; send samples for a trial closing.
