9. SPARE PARTS
Alfa Laval ViscoLine™-VLC heat exchangers are welded units that have a minimal
requirement for spare parts.
The only possible spare part required, is the gaskets for the SMS unions (product,
inlet and outlet unions) and gaskets on the flanged (service media, inlet and outlet)
connections.
It is, usually necessary merely to replace gaskets (for unions and flanges) at
designed service intervals or in the event of a leak.
The table below summarises the sizes of connections used:
