FAQ
Q1: Dab tsi yog qhov txawv ntawm TP2 tooj liab raj thiab ASTM C12200 rau HVAC daim ntawv thov?
TP2 tooj liab raj yog Suav ncaj qha sib npaug rau ASTM C12200 (DHP - Deoxidized High Phosphorus Copper). Ob leeg muaj 0.015%-0.040% phosphorus thiab hloov pauv tau rau cov cua txias txias kab thiab HVAC systems.
Q2: Qib twg, T2 lossis TU1, muaj hluav taws xob ntau dua rau cov khoom siv hluav taws xob?
T2 tooj liab raj (Ntau dua lossis sib npaug ntawm 99.90% Cu) muaj cov khoom siv hluav taws xob zoo tshaj plaws rau cov khoom siv hluav taws xob feem ntau. TU1 lub raj tooj liab (Ntau dua lossis sib npaug ntawm 99.97% Cu) muab qhov tshwj xeeb conductivity tab sis feem ntau tau teev tseg tsuas yog rau siab -kawg hluav taws xob uas xav tau ultra- cov ntsiab lus oxygen tsawg. Rau cov txheej txheem hluav taws xob, T2 yog tus nqi - qhov kev xaiv zoo dua.
Q3: TP2 tooj liab raj puas tuaj yeem welded yam tsis muaj kev pheej hmoo hydrogen embrittlement?
Yog lawm. TP2 tooj liab raj muaj 0.015% -0.040% phosphorus ua deoxidizer, uas tshem tawm cov kev pheej hmoo ntawm hydrogen embrittlement thaum vuam. Qhov no ua rau TP2 yooj yim dua rau vuam dua qib T2, uas tsis muaj phosphorus ntxiv. TP2 yog qib pom zoo rau kev siv vuam ntau zaus.
Q4: Vim li cas TU1 lub raj tooj liab pom zoo rau kev sib txuas ntawm lub qhov ncauj (trumpet lub qhov ncauj)?
TU1 oxygen- tooj liab dawb muaj cov pa oxygen tsawg heev (<0.002% P) and more uniform internal grain structure with reduced secondary phase particles. This results in superior strain distribution uniformity during flaring, producing more stable, reliable, and leak-free flare connections compared to TP2 or T2 grades.
Q5: Dab tsi yog qhov sib npaug European tus qauv qib rau T2 tooj liab raj?
T2 tooj liab raj (Ntau dua los yog sib npaug rau 99.90% ntshiab tooj liab) yog sib npaug rau EN CW004A. Rau kev txiav txim thoob ntiaj teb, ib txwm thov daim ntawv pov thawj rau ASTM C11000 lossis EN CW004A kom ntseeg tau tias muaj kev sib raug zoo nrog T2 specifications.
Q6: Puas yog TP2 lub raj tooj liab haum rau cov dej haus (haus dej)?
Yog lawm. TP2 tooj liab raj lub phosphorus deoxidized muaj pes tsawg leeg muab zoo corrosion kuj, ua rau nws haum rau ob qho tib si kub thiab txias potable dej mov kab. Txawm li cas los xij, ib txwm txheeb xyuas cov kav dej hauv zos, vim qee thaj tsam yuav xav tau cov ntawv txhuas tshwj xeeb -dawb lossis qis- cov ntawv pov thawj txhuas.
Q7: Tus nqi sib txawv ntawm TU1 thiab TP2 tooj liab raj yog dab tsi?
TU1 tooj liab raj yog tus nqi siab dua TP2 tooj liab raj vim nws xav tau ntau lawm (lub tshuab nqus tsev melting, ultra- siab purity tswj). Rau cov ntawv thov uas tsis tas yuav tsum tau muaj ductility lossis flaring kev ntseeg siab, TP2 muaj txiaj ntsig zoo dua. Thov ib daim ntawv cog lus nrog koj cov qib tshwj xeeb, qhov loj me, thiab ntau npaum li cas rau tus nqi them.
Q8: T2 tooj liab raj puas siv tau rau cov kab roj es tsis txhob TP2?
T2 tooj liab raj siv tau rau cov roj kab tab sis tsis pom zoo. TP2's phosphorus ntxiv muab qhov zoo tshaj plaws weldability thiab corrosion kuj tshwj xeeb rau kev siv roj kab. T2 tsis muaj qhov ua kom zoo dua no thiab tej zaum yuav xav tau kev tiv thaiv ntxiv. Rau cov roj kab, TP2 yog kev lag luam - qib nyiam.
Q9: Dab tsi yog qhov tsawg kawg nkaus xaj kom muaj nuj nqis (MOQ) rau TU1 tooj liab raj hauv qhov ntau thiab tsawg?
MOQ rau TU1 tooj liab raj txawv ntawm txoj kab uas hla thiab phab ntsa thickness. Rau qhov ntau thiab tsawg, MOQ yuav pib los ntawm 500 kg. Rau kev cai qhov ntev, cia siab tias yuav muaj MOQ siab dua thiab ntev dua cov sij hawm ua. Hu rau tus neeg muag khoom ncaj qha nrog koj cov lus qhia meej kom paub meej.
Q10: Puas yog TP2 tooj liab raj ua tau raws li ASTM B280 tus qauv rau cua txias?
Yog lawm. TP2 tooj liab raj tuaj yeem muab tau raws li ASTM B280 cov cai (tus qauv rau seamless tooj liab raj rau cua txias thiab tub yees kev pab cuam). Ib txwm thov daim ntawv pov thawj Mill Test (MTC) qhia ASTM B280 ua raws li koj qhov kev txiav txim tshwj xeeb.
Q11: Dab tsi yog lub sij hawm txhuas txhuas rau kev txiav txim ntawm T2 tooj liab raj?
Tus qauv coj lub sij hawm rau T2 tooj liab raj xaj xaj yog 7-15 hnub tom qab kev txiav txim pom zoo thiab tso nyiaj. Kev cai qhov ntau thiab tsawg lossis tsis yog tus qauv tempers yuav xav tau 15-25 hnub.Hu rau pab pawg muag khoom nrog koj qhov ntau thiab cov lus qhia tshwj xeeb rau lub sijhawm ua khoom lag luam raug.
Q12: Koj puas muab cov qauv dawb ntawm TP2 tooj liab raj rau kev ntsuas vuam?
Txoj cai qauv txawv ntawm tus neeg muag khoom. Ntau tus neeg muag khoom muab cov qauv qauv (feem ntau 300mm-500mm ntev) rau tus nqi nominal, uas yuav rov qab tau raws li kev txiav txim ntau lawm. Qhia koj qib uas xav tau (TP2), txoj kab uas hla, phab ntsa thickness, thiab vuam lub hom phiaj thaum thov cov qauv.
