Composition
Stainless steel snap rings, spring bands, are made from stainless steel equivalent to Aisi301.
Strip supplies
The stainless steel strip is rolled to produce a mirror finish. The bright surface improves the resistance to corrosion.
Production
The strip is firstly machined to remove the sharp corners. This makes handling safer during sewing into the filter bags and protects the filter bag fabric from damage during operation.
The strip is then cut into ring lengths. The ring lengths are then fastened together using stainless steel eyelets/rivets. By using stainless steel eyelets the risk of electrolytic corrosion between the strip and the eyelets is eliminated. Spot welding can also be performed when required.
Ring dimensions
Rings can be supplied in any diameter size from a minimum of 95mm. Smaller rings can be supplied from some widths of stainless steel strip.

When thicker rings are required we can supply a laminated type of ring made from our standard strip sizes. This gives a stronger spring character but retains the additional flexibility provided by a thinner strip thickness.
We are happy to discuss enquiries for rings manufactured from other dimensions of stainless steel strip. |
