Copper tube, metric (EN 1057): OD × wall for 6 to 219 mm, R220 / R250 / R290 tempers, + metric Types A, B, C and 100 mm sections — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/copper-tube-metric-en-1057/ (sheet CC BY 4.0) Basis: Engineering ToolBox's EN 1057 table (nominal OD × wall grid, typical X / Y sizes), cross-checked against Pirtek's R250 listing (OD and ID) and a Halcor product certificate; metric Types A, B, C from Enggcyclopedia Catalog version: 2026-10-20 Overall (mm): length 219.0, width 219.0, height 100.0 - EN 1057 is the European standard for round seamless copper tube for water, gas and heating. Tube is named by outside diameter in millimetres (6, 8, 10, 12, 15, 18, 22, 28, 35, 42, 54, 66.7 / 67, 76.1 / 76, 88.9, 108, 133, 159 ...) and the wall is chosen separately. The standard itself was not read; the numbers are Engineering ToolBox's. Its page grid lists nominal ODs 6, 8, 10, 12, 14, 15, 16, 18, 22, 28, 35, 40, 42, 54, 64, 66.7, 76.1, 88.9, 108, 133, 159, 219, 267 mm against walls 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.1, 1.2, 1.5, 2.0, 2.5, 3.0 mm; the grid cells are empty in the text read, so which OD comes in which wall is taken from the 'typical available' list below. - Typical plain straight tubes (R250 and R290, 3 m and 6 m lengths) with two wall thicknesses per OD, headed X and Y on the source page (the page does not define the letters): 6 / 8 / 10 mm 0.6 and 0.8; 15 mm 0.7 and 1.0; 22 and 28 mm 0.9 and 1.2; 35 and 42 mm 1.2 and 1.5; 54 mm 1.2 and 2.0; 67 mm 1.2 and 2.0; 76 mm 1.5 and 2.0; 108 mm 1.5 and 2.5; 133 mm 1.5 only; 159 mm 2.0 only; 219 mm 3.0 only (6 m only). Pirtek's R250 listing prints OD and ID for 15 to 67 mm, and (OD − ID) ÷ 2 gives 0.7, 0.9, 0.9, 1.2, 1.2, 1.2, 1.2 mm, equal to the X column (a derivation made here). A Halcor product certificate (EN 1057:2006+A1:2010) lists further sizes it makes, without labelling the two numbers, read here as OD × wall: R250 12 × 1.0, 15 × 1.0, 18 × 1.0, 22 × 1.0, 28 × 1.0, 35 × 1.5, 42 × 1.5, 54 × 1.5; R290 10 × 0.8, 12 × 1.0, 15 × 1.0, 18 × 1.0, 22 × 1.0, 28 × 1.0, 28 × 1.2, 35 × 1.5, 42 × 1.5, 54 × 1.5, 64 × 2.0, 76.1 × 2.0, 88.9 × 2.0, 108 × 2.5. So 15 × 1.0 and 22 × 1.0 are made as well as the X / Y walls above. - Disagreement shown, not resolved: Engineering ToolBox's grid has the nominal ODs 66.7 and 76.1 mm, while its typical-size list and Pirtek print 67 and 76 mm, and Halcor prints 76.1. The sections on this page are drawn only at ODs that are the same in every source (6 to 54, 108, 133, 159, 219 mm), not at 67 / 76. - Tempers (EN 1173 designations; the page says the R number is the tensile strength in MPa), as Engineering ToolBox prints them: R220 annealed ('soft'), 6 to 54 mm, 40 % elongation, 40–70 HV5; R250 half hard, 6 to 66.7 mm, 20 %, 75–100 HV5; R290 hard, 6 to 159 mm, 5 %, 95–120 HV5. Plain coils are R220: 15 × 1.0 and 22 × 1.2 mm in 25 m coils; PVC-covered coils are R220: 8 × 0.6, 10 × 0.7, 15 × 1.0, 22 × 1.2 (25 m) and 28 × 1.2 (20 m). Chrome-plated R250 / R290 tube: 15 × 0.7, 22 × 0.9, 28 × 0.9, 35 × 1.0, 42 × 1.0, 54 × 1.0 mm. - A second metric table, for the case where 'metric copper tube' means something other than EN 1057: Enggcyclopedia prints OD, wall, tolerance and mass per metre in mm for 'Types A, B and C' of ASTM B88 tube; the page does not name the edition (B88M) or say how A, B and C relate to US Types K, L and M, so no mapping is claimed. Mass per metre follows (OD − wall) × wall to within about 6 % across all sizes of each type (a check made here). The tolerance column is not copied. - Compare with US sizes: US Type L 3/4 in is 22.225 × 1.143 mm, close to the 22 mm EN 1057 tube but not the same OD, so check the fitting's stated tube size, not just 'three-quarter'; see copper-tube-types-k-l-m-dwv-astm-b88-b306. Files: 100 mm hollow sections of the X and Y walls at the ODs the sources agree on; the length is Xem's example length. table OD, mm wall, mm ID, mm (OD − 2 × wall) check / mass per metre EN 1057 'X'
