ISO 2852 clamp ferrules (welded-type liners), 25 to 219.1 mm tube: bore, neck, flange, length, groove — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/sanitary-clamp-iso-2852-ferrules/ (sheet CC BY 4.0) Basis: ISO 2852:1993 Table 2 (welded-type liner) and Figure 1 (face profile), read from ISO's public sample pages; 38 mm row cross-checked against Alfa Laval's ISO 2852 ferrule listing Catalog version: 2026-10-20 Sizes: see table below - Dimensions are exact nominal (no tolerance). Nominal size = tube OD in mm (ISO 2037 / ISO 1127 tube). C6 bore, C8 neck OD at the weld end, C7 flange OD, F2 overall length, C2 gasket-groove diameter. - Face per ISO 2852 Figure 1: flat from the bore to C7, one gasket groove on C2 1.6 deep with R1.2 bottom and 23° walls, flange 2.85 thick, 20° clamp back cone. Small edge radii (P1, P2 0.8, R2 2) are not drawn. - Same clamp flanges as the inch and DIN 32676 series: 50.5, 64, 77.5, 91, 106 and 119 mm flanges take the matching tri-clamp clamp and Type B gasket. 40 mm tube already moves to the 64 mm flange (DIN 32676 DN40 stays on 50.5). - Files for 25, 38, 40, 51, 63.5, 76.1, 88.9 and 101.6 mm. 114.3 to 219.1 are listed but not drawn: the face-profile column for the large sizes could not be read cleanly from the sample pages. - ISO 2852 also has an expanded-type liner (tube rolled into it, 12 to 76.1 mm, Table 1): bore C5 = tube OD, neck C1 = tube OD + 4.0 to 5.8, length F3 16 to 30. That type is not on this page. tube OD mm C6 bore C8 neck OD C7 flange F2 length C2 groove file 25 22.6 25.6 50.5 21.5 43.5 yes 33.7 31.3 34.3 50.5 21.5 43.5 no 38 35.6 38.6 50.5 21.5 43.5 yes 40 37.6 40.6 64.0 21.5 56.5 yes 51 48.6 51.6 64.0 21.5 56.5 yes 63.5 60.3 64.1 77.5 21.5 70.5 yes 70 66.8 70.6 91.0 21.5 83.5 no 76.1 72.9 76.7 91.0 21.5 83.5 yes 88.9 84.9 89.8 106.0 21.5 97.0 yes 101.6 97.6 102.5 119.0 21.5 110.0 yes 114.3 110.3 115.6 130.0 28.0 122.0 no 139.7 135.7 141.2 155.0 28.0 146.0 no 168.3 163.1 170.0 183.0 28.0 174.0 no 219.1 213.9 221.2 233.5 28.0 225.0 no Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - ISO (sample pages via iTeh): ISO 2852:1993 Stainless steel clamp pipe couplings for the food industry: Table 2 welded-type liner, Figure 1 face — web — Publisher's page; dimensions are facts — https://cdn.standards.iteh.ai/samples/7851/ed46f309bca445d2b99cf80609e01429/ISO-2852-1993.pdf - ISO (sample pages via iTeh): ISO 2852:1974 clamp liners: face profile and flange / groove diameters — web — Publisher's page; dimensions are facts — https://cdn.standards.iteh.ai/samples/7850/eb49c396488d408c8ced3e2961d76cf3/ISO-2852-1974.pdf - Alfa Laval: Clamp ferrule 38 mm, ISO 2852 (1279889): OD/ID 38.60/35.60, A 50.50, B 21.50 — web — Publisher's page; dimensions are facts — https://shop.alfalaval.com/en-bz/hygienic-fittings-iso-en-10357-d--3261317/clamp-ferrule-38mm--1279889- Free files (CC BY 4.0, Xem Studio; STEP + STL, 8 parts): https://xemstudio.com/files/hardware/sanitary-clamp-iso-2852-ferrules/index.json API: https://xemstudio.com/api/geometry?object=sanitary-clamp-iso-2852-ferrules
