Consumables

Image	Type	Name	Part number	Description	Add to quote
	Consumable	Bottle roll set	R-15-2RBL	For tube expansion after welding, allowing the rolls to bypass the hardened weld area and expand the tube behind the weld.	Quantity
	Consumable	Double radius roll set	R-15-2R	For expansion in secondary tube sheets and step rolling in thick tube sheets, providing a smooth transition during expansion.	Quantity
	Consumable	Mandrel	M-11	Tapered drive component that forces the rolls outward, expanding the tube against the tube sheet.	Quantity
	Consumable	Standard roll set	R-15	Standard rolls, delivered with expander. For regular tube expansion in single and primary tube sheets of condensers and heat exchangers.	Quantity
