EN 10216-5 1.4301 Stainless Hlau Tube rau Kub Exchangers
Tso lus
Vim li cas 1.4301 (304) stainless hlau raj, txawm hais tias ua raws li cov qauv, tseem raug kev txom nyem los ntawm kev tawg, vuam corrosion, lossis teeb meem kev teeb tsa hauv cov phiaj xwm hluav taws xob? Qhov tseem ceeb yog nyob rau hauv kev kho weld, kev kho cua sov, thiab qhov tseeb qhov tseeb thaum lub sij hawm tsim khoom- cov yam ntxwv uas ncaj qha txiav txim siab qhov kev ua tau zoo ntawm 1.4301 cov cua kub exchanger raj.
Peb EN 10216-5 1.4301 Stainless Hlau Tube rau Cov Hluav Taws Xob Hluav Taws Xob yog tshwj xeeb tsim los rau siab - xav tau kev sib pauv cua sov. Cov raj feem ntau muab nkag rau hauv W1 (kub tiav + kho cua sov + descaled) lossis W2 (txias tiav + kho cua sov + descaled / ci annealed) cov xwm txheej. Ntawm cov no, W2 tus mob, nrog rau kev ua haujlwm txias thiab ci ntsa iab, muab qhov chaw qis qis thiab qhov siab dua qhov tseeb, txo cov dej tsis kam thiab txo qhov fouling, ua rau nws yog qhov kev xaiv zoo tshaj rau kev siv hluav taws xob sib hloov.
Nyob rau hauv cov nqe lus ntawm corrosion kuj, 1.4301 stainless hlau raj tau dhau qhov kev ntsuam xyuas intergranular corrosion raws li EN ISO 3651-2, xyuas kom meej tias cov khoom tsis raug rau rhiab heev tom qab vuam lossis raug kub. Qhov no yog qhov tseem ceeb tshwj xeeb rau kev pabcuam mus sij hawm ntev hauv ib puag ncig uas muaj dej, chav dej, lossis cov xov xwm me me.
Hais txog qhov raug thiab qhov ncaj, peb nruj me ntsis ua raws EN ISO 1127 tus qauv, txais yuav D3 / T3 lossis D4 / T4 cov chav kawm kam rau ua. Qhov no ua kom lub siab sab nraud precision thiab qhov ncaj ncaj, tso cai rau lub raj xa mus rau lub sijhawm sib dhos, tiv thaiv kev thaiv lossis tsis zoo hauv cov ntawv raj thiab baffles, thiab txhim kho kev txhim kho kev ua haujlwm zoo.

Kev soj ntsuam zoo
Txhawm rau ua kom tau raws li cov kev cai nruj rau kev nyab xeeb siab thiab raj -rau-tubesheet sib koom ua ke kev ncaj ncees hauv cov khoom siv hluav taws xob, cov txheej txheem tshuaj xyuas nruj me ntsis ua raws li TC1 / TC2 (Test Category) specifications:
Kev Ntsuas Tshuaj: Ua tau siv lub spectrometer (PMI).
Flaring thiab Flattening Tests: xyuas kom meej tias cov raj tsis pom qhov tawg ntawm qhov muag liab qab tom qab nthuav dav mus rau 1.15-1.2 npaug ntawm nws txoj kab uas hla.
100% Eddy Current Testing (ET) / Hydrostatic Testing: Ua raws li EN ISO 10893 tus qauv kom ntseeg tau tias lub raj phab ntsa tsis pub dhau los ntawm - phab ntsa tsis xws luag thiab xau.
Kev Ntsuas Ultrasonic (UT): Siv rau TC2 qeb tubing txhawm rau txhawm rau txhawm rau sab hauv longitudinal thiab transverse micro- tawg nyob rau hauv lub raj phab ntsa.
Kev ntim khoom
End Caps: Ob qhov kawg ntawm txhua lub raj yuav tsum tau muab nrog lub kaus mom tiv thaiv kom tsis txhob muaj plua plav nkag los yog noo noo nyob rau hauv cov phab ntsa sab hauv.
Export-Qib Fumigated Plywood Cases: Cov raj tau muab tso rau hauv cov txheej hauv cov ntoo crates, nrog rau txhua txheej sib cais los ntawm cov ntoo los yog cov ntaub ntawv cushioning.
Kev txiav txim siab tshwj xeeb:
Kos Npe: Sab nrauv ntawm lub crate yuav tsum tau cim kom meej nrog cov ntaub ntawv hauv qab no, Qhov Loj (OD x WT x L), Thaum tshav kub kub tsis muaj., Qhov hnyav, nrog rau cov cim ceeb toom xws li "Tsis Txhob Txhaum" thiab "Kua kom qhuav."
