EN 10217-7 stainless hlau raj yog dab tsi?
EN 10217-7 yog cov khoom siv nyob sab Europe tus qauv uas qhia txog cov txheej txheem kev xa khoom rau welded stainless hlau raj ntawm ncig hla ntu. Nws ua tau raws li qhov yuav tsum tau ua ntawm Cov Khoom Siv Siab Cov Lus Qhia (PED 2014/68 / EU), thiab cov raj no tau tsim tshwj xeeb los tiv thaiv lub siab sab hauv thiab tiv thaiv corrosion thoob plaws ambient, qis, lossis siab kub ib puag ncig.
Txawm hais tias koj xav tau tus qauv EN 10217-7 raws TP304/TP316L welded raj lossis cov kev daws teeb meem tshwj xeeb rau kev ua haujlwm siab tshwj xeeb, GNEE muab cov kev taw qhia txog kev xaiv cov khoom siv txhim khu kev qha, cov sij hawm sib tw ua tau zoo, thiab kev txhawb nqa dav dav los ntawm kev nug thawj zaug mus txog rau qhov kawg ntawm kev xa khoom.
GNEE muab welded stainless hlau raj ua raws li EN 10217-7 tus qauv. Peb cov khoom lag luam suav nrog kev xaiv dav ntawm qib steel, suav nrog 1.4301, 1.4307, 1.4401, 1.4404, 1.4541, 1.4571, 1.4462, thiab 1.4410. Peb txhawb nqa sab nraud txoj kab uas hla ntawm 6 hli mus rau 114.3 hli thiab phab ntsa thicknesses ntawm 0.5 hli mus rau 25 hli. Qhov no suav nrog cov qauv siv dav dav xws li 21.3 hli, 33.7 hli, 42.4 hli, 48.3 hli, 60.3 hli, 88.9 hli, thiab 114.3 hli, nrog rau cov kev xaiv loj tuaj yeem hloov tau. Tsis tas li ntawd, peb cov raj muaj nyob rau hauv ntau yam kev xa khoom, suav nrog cov tshuaj annealed & pickled, ci annealed, thiab mechanically polished.

Kuv yuav tsum xaiv dab tsi kam rau ua rau lub tshav kub exchanger?
Rau cov khoom siv hluav taws xob, ISO 1127 Class D4 / T4 tau pom zoo.
Standard raj feem ntau yog D3 / T3 (± 0.75% OD / ± 10% WT).
D4 / T4 (± 0.5% OD / ± 7.5% WT) ua kom muaj kev sib haum xeeb rau hauv lub raj ntawv qhov, uas yog ib qho tseem ceeb rau kev vam meej tube expansion (dov) thiab tiv thaiv kom tsis txhob xau ntawm lub raj - mus rau -tubesheet sib koom.
Thaum xa daim RFQ (Thov kom Quote) rau EN 10217-7, suav nrog cov ntsiab lus no:
Txheem: EN 10217-7.

Kev Tswj Xyuas Zoo
Rau qhov tseem ceeb siab- cov ntawv thov kev coj tus kheej, peb muab 100% eddy tam sim no kuaj, ntsuas hydrostatic, PMI (Positive Material Identification), thiab kev soj ntsuam qhov ntev, nrog rau cov ntaub ntawv pov thawj raws li EN 10204 3.1 los xyuas cov tshuaj muaj pes tsawg leeg, cov khoom siv kho mob, thiab cov khoom traceability.
Txheem ntim
Rau lub voj voog welded stainless hlau kav raws li EN 10217-7 tus qauv, GNEE ntiav cov kws tshaj lij kev ntim khoom. Ua ntej kev ntim khoom, txhua lub yeeb nkab yuav raug tshuaj xyuas rau qhov chaw nyob, qhov ntev, qhov ntau, cov cim, thiab cov khoom siv traceability; Cov kev tiv thaiv tsim nyog raug xaiv raws li cov yeeb nkab specifications, nto tiav, thiab qhov yuav tsum tau ua.
Cov kav dej txheem feem ntau yog bundled siv steel straps los yog siab -lub zog PP pluaj, nrog rau txhua pob khoom hnyav li ntawm 500 mus rau 1,500 kg (nyob ntawm cov yeeb nkab txoj kab uas hla thiab phab ntsa thickness). Cov kaus mom yas kawg yog haum rau ob qho kawg ntawm cov kav dej kom tsis txhob muaj plua plav lossis ya raws thiab tiv thaiv kev cuam tshuam ntawm txhua yam thaum tuav.
FAQ
Qhov txawv ntawm TC1 thiab TC2 yog dab tsi?
TC1 (Test Qeb 1): Yuav tsum muaj kev ntsuam xyuas yooj yim thiab kev xau -tightness test. Nws yog feem ntau siv tau rau qis-siab lossis tsis yog- daim ntawv thov tseem ceeb.
TC2 (Test Qeb 2): Yuav tsum tau 100% tsis yog- kuaj kev puas tsuaj (NDT, feem ntau yog los ntawm kev ntsuas ultrasonic lossis eddy tam sim no) ntawm cov vuam seam thiab suav nrog kev kuaj xyuas cov cuab yeej nruj dua. Cov hlab ntsha tseem ceeb thiab cov khoom siv hluav taws xob feem ntau xav tau TC2 tus qauv.
Dab tsi yog qhov txawv ntawm EN 10217-7 thiab ASTM A249?
Teb: Txawm hais tias ob qho tib si qauv npog welded stainless hlau raj rau cov khoom siv hluav taws xob thiab kev siv siab, muaj qhov sib txawv hauv qab no:
Qeb xeem: EN 10217-7 ntiav TC1 thiab TC2 kev faib tawm thiab suav nrog NDT cov cai tshwj xeeb; conversely, ASTM A249 qhia txog cov txheej txheem ntawm qhov yuav tsum tau ntsuas cov cuab yeej cuab tam (xws li kev ntsuas rov qab khoov) uas txawv ntawm cov hauv EN tus qauv.
Kev kam rau ua: Hais txog qhov ntev, EN 10217-7 hais txog EN ISO 1127 tus qauv, thaum ASTM A249 ua raws li tus qauv ASTM A1016.
Dab tsi yog qhov txawv ntawm EN 10217-7 welded raj thiab EN 10216-5 seamless raj?
Tsis tas li. Raws li European tsim cov cai (xws li EN 13445), qhov sib txuas ntawm 0.85 feem ntau yog siv rau welded hlab, thaum qhov tseem ceeb ntawm 1.0 yog siv rau seamless raj.
Txhawm rau siv EN 10217-7 steel tubes nrog qhov sib npaug ntawm 1.0, cov raj yuav tsum ua tau raws li TC2 cov cai (piv txwv li, dhau 100% NDT), thiab cov khoom siv vuam yuav tsum suav nrog hauv cov qauv tsim. Zuag qhia tag nrho, piv rau seamless hlab, welded hlab yog tus nqi ntau dua thiab muab cov phab ntsa thickness zoo dua qub.
