Title: Zinc exclusion sleeve for screwed sockets, threaded nipples, bolts, threaded nut holes and bores
Inventor: KLEIN HERMANN
IPC: C23C2/34
Filed: 1993-05-10
Abstract: In hot galvanising operations, the practice hitherto has been to coat areas which are not to be galvanised with a heat-resistant paint or, in the absence of any other effective possibility, simply to galvanise these areas along with the rest and laboriously finish them later on. The novel method makes it possible to prevent galvanising in the desired areas by means of the zinc exclusion sleeves. Exclusion of the zinc is ensured by the precisely placed zinc exclusion sleeves since the contact pressure on the glass- or mineral-fibre sleeves exerted by the supporting tubes prevents penetration of the molten zinc. The zinc exclusion sleeves are suitable for preventing zinc deposition during hot galvanising.
