GUTH VENTILTECHNIK | FLUID PROCESS GROUP technical information Change of standard DIN 11850 At the beginning of 2014 the new European tube standard DIN EN 10357 has been put into effect by the CEN (European Committee of Standardisation). This DIN EN 10357 replaces DIN 11850. DIN EN 10357 has been elaborated for longitudinally welded stainless steel tubes for the food and chemical industry. Fundamental amendments compared to DIN 11850 are as follows: The tube series 1 and 2 are replaced by the series A to D or completed respectively.  Series A replaces DIN 11850 series 2  Series B replaces DIN 11850 series 1  Series C corresponds to ISO dimensions  Series D corresponds to OD and SMS dimensions DIN EN 10357 Austenitic, austenitic-ferritic and ferritic longitudinally welded stainless steel tubes for the (formerly DIN 11850) food and chemical industry Use: Food, pharmaceutical and chemical industry Materials: AISI 304/AISI 304L, AISI 316L Dimensions Tube length: 6,000 mm, smooth ends and free of burrs Limit deviation: DIN EN ISO 1127 Size DN 10 15 20 25 32 40 50 65 80 100 125 150 200 Series A Tube outside diameter 13 (±0.1) 19 (±0.1) 23 (±0.12) 29 (±0.15) 35 (±0.18) 41 (±0.21) 53 (±0.27) 70 (±0.35) 85 (±0.43) 104 (±0.78) 129 (±0.97) 154 (±1.16) 204 (±1.53) Wall thickness 1.5 (±0.15) 2 (±0.2) Working pressure (bar) 20° C 355 242 200 159 131 112 87 87 72 59 47 39 30 Working pressure (bar) 150° C 219 150 124 98 81 69 53 54 44 36 29 24 18 Weight (kg/m) 0.43 0.66 0.81 1.03 1.26 1.50 1.90 3.43 4.16 5.03 6.36 7.49 10.12 Series B Tube outside diameter 12 (±0.1) 18 (±0.1) 22 (±0.11) 28 (±0.15) 34 (±0.18) 40 (±0.21) 52 (±0.27) Calculation series B, A calculation value material 1.4031 according to DIN EN 10217-7 and DIN EN 10088-2 product Form C (cold rolled strip) permissible calculation tension welding = 100 % Wall thickness 1 (±0.1) Working pressure (bar) 20° C 256 170 139 105 90 76 59 Working pressure (bar) 150° C 158 105 86 67 55 47 36 Weight (kg/m) 0.27 0.42 0.51 0.66 0.82 0.97 1.26
