Naval Shaft Liners
Spunalloys supports many of the world’s navies with the provision of equipment for surface and subsurface propulsion systems.
Naval shaft liners are traditionally very long in length and require a heavy poured weight, so their successful supply requires all of Spunalloys’ experience and infrastructure. Naval shaft liners can be supplied in various anti-seawater corrosion resistant alloys such as gunmetal, tin and phosphor bronze, nickel aluminium bronze and Inconel. Spunalloys has in-house machining capabilities enabling liners to be supplied either proof or finish machined. Finish machining of these items is generally carried out in the bore, but ‘split’ liners can also be provided proof or finish machined as required.
Spunalloys has developed unique and proprietorial solutions to meet the stringent acceptance criteria demanded by naval shaft liners. Spunalloys carries approvals for many major 1st and 2nd tier organisations including UK MOD Approval to manufacture DEF STAN 02-830 (LG4) shaft liners, in accordance with DEF STAN 02-304 part 1.
