ASTM A213 TP317L Stainless Hlau Tube Thaum tshav kub kub Exchanger
ASTM A213 TP317L yog qhov qis-carbon, molybdenum-cov kabmob austenitic stainless hlau raj tshwj xeeb tsim los siv rau hauv cov khoom siv hluav taws xob, boilers, thiab superheaters ua haujlwm nyob rau hauv siab -kub thiab corrosive heev. Lub npe "L" qhia txog cov ntsiab lus qis carbon (< 0.03%), which, compared to standard 317 stainless steel, provides superior resistance to intergranular corrosion as well as enhanced weldability.

Hauj lwm lawm
Gnee Steel (Tianjin) Co., Ltd. yog ib qho ntawm feem kev manufacturers thiab lwm tus neeg ntawm astm a213 tp317l stainless hlau raj kub exchanger nyob rau hauv Suav teb. Nrog kev paub ntau, peb sov siab txais tos koj rau cov lag luam wholesale customized astm a213 tp317l stainless hlau raj kub exchanger los ntawm peb lub hoobkas. Rau nqe kev sab laj, tiv tauj peb.
Vim li cas cov tshuab hluav taws xob hloov hluav taws xob ua haujlwm nyob rau hauv ib puag ncig corrosive heev-xws li chloride-muaj lossis acidic media- tseem raug kev txom nyem los ntawm pitting, to, thiab txo kev pab cuam lub neej, txawm tias cov qauv stainless hlau raj siv? Qhov tseem ceeb yog nyob rau hauv seb cov khoom siv tshuaj lom neeg muaj pes tsawg leeg, kev kho cua sov zoo, thiab kev tsim khoom ua tau raws li qhov xav tau ntawm cov xwm txheej hnyav.
GNEE's ASTM A213 TP317L Stainless Hlau Tube rau Cov Hluav Taws Xob Hluav Taws Xob yog tsim los nrog kev tswj xyuas nruj thiab ua raws li cov txheej txheem kev daws teeb meem ntawm ntau dua lossis sib npaug rau 1040℃tom qab txias txias. Cov txheej txheem no ua kom tiav kev sib cais ntawm cov carbide, ib qho microstructure zoo li qub, thiab txo kev ntxhov siab zoo, txhim kho corrosion kuj thiab ntev - lub sijhawm ua haujlwm ruaj khov. Hauv kev siv cov tswv yim, tus nqi corrosion tsis ua haujlwm tuaj yeem txo los ntawm kwv yees li 30%.
TP317L yog siab-molybdenum, qis- carbon austenitic stainless hlau nrog cov tshuaj muaj pes tsawg leeg ntawm Cr 18–20%, Ni 11–15%, Mo 3–4%, thiab C Tsawg dua lossis sib npaug li 0.03%. Nws raug soj ntsuam raws li ASTM A262 Xyaum A lossis E kom ntseeg tau tias muaj kev tiv thaiv rau kev sib xyaw ua ke tom qab vuam lossis siab - qhov kub thiab txias. Ua tsaug rau nws cov ntsiab lus molybdenum siab dua, TP317L muaj kev tiv thaiv zoo tshaj rau pitting thiab crevice corrosion piv rau 316L, ua rau nws tshwj xeeb tshaj yog haum rau chloride - nplua nuj thiab tshuaj ua ib puag ncig.
Nyob rau hauv cov nqe lus ntawm cov neeg kho tshuab kev ua tau zoo, lub hardness ntawm ASTM A213 TP317L tshav kub exchanger tubes yog nruj me ntsis tswj ntawm tsawg tshaj li los yog sib npaug rau HRB 90, kom ntseeg tau zoo heev ductility thiab tube expanding kev ua tau zoo, thiab tiv thaiv microcracks los yog tsis ua hauj lwm thaum lub raj - mus rau - tubesheet installation. Peb nruj me ntsis ua raws li ASTM A213 cov qauv, tswj cov txheej txheem sab nraud nyob rau hauv ± 0.3% thiab phab ntsa thickness hauv ± 10%, thaum tseem muab cov phab ntsa thickness tsawg kawg nkaus raws li qhov yuav tsum tau ua.

FAQ
Q: Vim li cas lub sijhawm ua haujlwm rau TP317L ntev dua 304L / 316L?
A: TP317L yog qib tshwj xeeb. Steel mills tsis tas yuav khaws 317L billets (niam kav) hauv Tshuag. Cov voj voog ntau lawm nyob ntawm qhov muaj cov khoom siv raw, thiab cov txheej txheem kos duab / dov rau siab -Mo alloys xav tau ntau dua ntawm cov tshuab.
Q: Cov ntaub ntawv dab tsi kuv yuav tsum tau txais nrog kev xa khoom?
A: Koj yuav tsum tau txais daim ntawv pov thawj Material Test (MTC) rau EN 10204 3.1 (lossis 3.2 yog qhov thib peb- yuav tsum tau kuaj xyuas tog).
Q: Tus nqi PREN rau TP317L yog dab tsi?
A: Pitting Resistance Equivalent Number (PREN) rau TP317L feem ntau yog nyob ntawm 28 txog 30, piv rau 24–25 rau 316L.
