CNAF Gasket Cutting to Your Drawing
Every AEROlite® grade above is cut in-house on two ATOM CNC flash cutters, for local plants and export orders alike. Digital cutting needs no die or mould, so there is no tooling charge for one-off shapes, odd sizes or small batches.
Three ways to specify a gasket:
- Drawing – send a dimensioned drawing and we cut to it.
- Sample – send a used gasket and we measure and reproduce it.
- Flange standard, size and class – ASME B16.21 ring or full-face gaskets by nominal pipe size and class; AS 2129, AS 4087, DIN and other standards to the dimensions you state.
| Standard sheet sizes | 1,500 x 1,500 mm, 1,500 x 3,000 mm, 2,000 x 3,000 mm |
| Sheet thicknesses | 0.4 mm to 6.0 mm, depending on grade (see each datasheet). Other thicknesses on request. |
| Thickness tolerance | To BS 7531 |
| Supply | Full sheets, or gaskets cut to drawing, sample or flange standard. |
