Cov npe qub thiab tshiab DIN

Tau ntau xyoo, ntau DIN cov qauv tau muab tso rau hauv ISO cov qauv, thiab yog li kuj yog ib feem ntawm EN cov qauv. Nyob rau hauv lub cource ntawm kev hloov kho ntawm European qauv serveral DIN cov qauv raug tshem tawm thiab hloov los ntawm DIN ISO EN thiab DIN EN.
Cov qauv siv yav dhau los xws li DIN 17121, DIN 1629, DIN 2448 thiab DIN 17175 txij li thaum feem ntau tau hloov los ntawm Euronorms. Cov Euronorms kom meej meej qhov txawv ntawm cov yeeb nkab cheeb tsam ntawm daim ntawv thov. Yog li cov qauv sib txawv tam sim no muaj nyob rau cov kav dej siv los ua cov khoom siv, cov kav dej lossis rau kev siv tshuab engineering.
Qhov kev sib txawv no tsis meej li yav dhau los. Piv txwv li, qhov qub St.52.0 zoo tau muab los ntawm DIN 1629 tus qauv uas tau npaj rau cov kav dej thiab cov khoom siv tshuab engineering. Qhov zoo no kuj tau siv rau cov qauv steel, txawm li cas los xij.
Cov ntaub ntawv hauv qab no piav qhia txog cov qauv tseem ceeb thiab cov hlau zoo nyob rau hauv cov txheej txheem tshiab ntawm cov qauv.

Seamless Yeeb Nkab thiab Tubes rau Kev Siv Siab

EN 10216 Euronorm hloov cov qauv qub DIN 17175 thiab 1629. Cov qauv no yog tsim los rau cov kav dej siv hauv kev siv siab, xws li cov kav dej. Qhov no yog vim li cas cov hlau zoo sib xws tau raug xaiv los ntawm tsab ntawv P rau 'Pressure'. Tus nqi uas ua raws li tsab ntawv no qhia qhov tsawg kawg nkaus yield zog. Cov ntawv xaiv tom ntej no muab cov ntaub ntawv ntxiv.

EN 10216 suav nrog ntau qhov chaw. Cov khoom uas cuam tshuam rau peb yog raws li nram no:

• TS EN 10216 - Ntu 1: Cov kav dej tsis-alloy nrog cov khoom tshwj xeeb ntawm chav sov
• TS EN 10216 Ntu 2: Cov kav dej tsis muaj hlau nrog cov khoom tshwj xeeb ntawm qhov kub siab dua
• TS EN 10216 Ntu 3: Cov kav dej hlau ua los ntawm cov hlau zoo rau txhua qhov kub thiab txias

Qee qhov piv txwv:

1. EN 10216-1, Zoo P235TR2 (yav tas los DIN 1629, St.37.0)
   P = Siab
   235 = Yam tsawg kawg nkaus tawm lub zog hauv N / mm2
   TR2 = zoo nrog cov khoom tshwj xeeb hais txog cov ntsiab lus txhuas, cuam tshuam qhov tseem ceeb thiab kev tshuaj xyuas thiab kev xeem. (Qhov sib txawv rau TR1, uas qhov no tsis tau teev tseg).
2. TS EN 10216-2 Zoo P235 GH (yav tas los DIN 17175, St.35.8 Cl. 1, boiler yeeb nkab)
   P = Siab
   235 = Yam tsawg kawg nkaus tawm lub zog hauv N / mm2
   GH = kuaj cov khoom ntawm qhov kub siab dua
3. EN 10216-3, Zoo P355 N (ntau dua lossis tsawg dua sib npaug rau DIN 1629, St.52.0)
   P = Siab
   355 = Yam tsawg kawg nkaus tawm lub zog hauv N / mm2
   N = normalized*

* Normalized yog txhais raws li: normalized (sov) dov los yog txheem annealing (ntawm ib tug min kub ntawm 930 ° C). Qhov no siv tau rau txhua yam khoom tsim los ntawm tsab ntawv 'N' hauv Euro Standards tshiab.
