FAQ

Dab tsi yog qhov txawv ntawm P275N, P275NH, P275NL1, thiab P275NL2?

Qhov sib txawv tseem ceeb yog nyob rau hauv qhov ntsuas kub ntawm qhov ntsuas kub thiab siv tau rau kev ua haujlwm. Tag nrho plaub qib muaj qhov tsawg kawg nkaus tawm lub zog ntawm ntau dua lossis sib npaug rau 275MPa (rau thickness Tsawg dua lossis sib npaug rau 16mm) thiab ua raws li EN 10028-3 tus qauv:

P275N: Kev ntsuam xyuas cuam tshuam ntawm -20 degree, haum rau cov hlab ntsha ntawm qhov kub thiab txias thiab cov kav dej dav dav;

P275NH: Kev ntsuam xyuas cuam tshuam ntawm -20 degree, optimized rau siab -kev ua haujlwm kub, hloov mus rau nruab nrab- rau-siab kub siab hauv qab 350℃;

P275NL1: Kev ntsuam xyuas cuam tshuam ntawm -40 degree, haum rau cov tso tsheb hlau luam qis thiab cov khoom sib cais hauv cov cheeb tsam txias;

P275NL2: Kev ntsuam xyuas cuam tshuam ntawm -50 degree, muab qhov zoo tshaj plaws ultra-low kub toughness, yoog rau cov khoom siv cryogenic xws li kua nitrogen / LNG systems.

Yuav ua li cas yog tus lej sib raug rau plaub qib no?

P275N: 1.0483;

P275NH: 1.0485;

P275NL1: 1.0488;

P275 NL2: 1.1104.

Puas yog thickness cuam tshuam kev ua haujlwm?

Yog, nws ua. Thaum lub thickness ntau tshaj 16 hli, lub zog tawm los maj mam txo qis (piv txwv li, Ntau dua lossis sib npaug ntawm 245MPa rau 63 ~ 100mm), thiab qhov qis - kub toughness kuj poob me ntsis. Rau ultra- qhov kub thiab txias ua hauj lwm tej yam kev mob nrog thickness ＞40mm, nws raug nquahu kom ua qhov tseem ceeb ntawm P275NL2 thiab nce qhov piv txwv rau kev ntsuam xyuas cuam tshuam.

Cov cuab yeej cuab tam tseem ceeb ntawm plaub qib yog dab tsi?

Yield Strength (ReH): Ntau dua los yog sib npaug rau 275MPa rau thickness Tsawg dua los yog sib npaug rau 16mm, me ntsis txo nrog nce thickness (xws li, Ntau tshaj los yog sib npaug rau 255MPa rau 40 ~ 63mm);

Tensile zog (Rm): 410 ~ 560MPa;

Impact Energy (KV): Ntau dua lossis sib npaug rau 27J rau txhua qhov cuam tshuam qhov kub thiab txias (cov khoom siv tsis tu ncua ua tau raws li ntau dua lossis sib npaug rau 40J txhawm rau txhim kho kev nyab xeeb dua);

Elongation (A): Ntau dua lossis sib npaug li 22% ~ 24% (hloov nrog tuab).

Dab tsi yog qhov ntau ntawm qhov muaj nyob?

Thickness: 6mm ~ 300mm;

Dav: 1500mm ~ 4800mm;

Ntev: 6000mm ~ 18000mm;

Customized txiav, drilling, thiab beveling cov kev pab cuam muaj, nrog tsawg kawg txiav loj ntawm 500 × 500mm.

Lub weldability zoo li cas, thiab cov lus pom zoo welding yog dab tsi?

Nws muaj qhov zoo tshaj plaws weldability (CEV Tsawg dua lossis sib npaug rau 0.43%), nrog cov kev pom zoo:

Vuam Consumables: E5515-C1 rau phau ntawv arc vuam, H08MnA + F55A4 flux rau submerged arc vuam, thiab ER50-6 rau roj arc vuam;

Preheating Requirement: Tsis muaj preheating yuav tsum tau thickness tsawg dua los yog sib npaug rau 30mm; preheat rau 100 ~ 150℃rau thickness ~ 30mm;

Interpass Kub: Tsawg dua los yog sib npaug rau 250 degree, nrog cov cua kub tswj ntawm 15 ~ 35kJ / cm;

Ncej -Kev kho cua sov (PWHT): Pom zoo rau cov phaj tuab (＞50mm) - kev ntxhov siab rau kev ntxhov siab ntawm 580 ~ 620℃rau 2 teev.

P275 series puas tuaj yeem hloov tau rau ASTM A516 Gr70 (American standard) lossis Q345R (Suav tus qauv)?

vs. ASTM A516 Gr70: Lub zog zoo sib xws, tab sis P275 series muaj qhov zoo dua qis dua -kub toughness. P275 series yog qhov nyiam rau cov haujlwm nyob sab Europe, thaum ASTM A516 Gr70 haum rau North American cov haujlwm;

vs. Q345R (GB 713): Q345R muaj lub zog tawm los ntau dua (Ntau dua lossis sib npaug rau 345MPa), tab sis P275 series ua tau zoo nyob rau hauv qis- qhov kub thiab txias (-20℃cuam tshuam) thiab qhov kub thiab txias. Rau cov haujlwm thoob ntiaj teb, nws raug pom zoo kom xaiv raws li EN tus qauv ua ntej.

Dab tsi yog qhov txawv ntawm P275NL1 / NL2 thiab 16MnDR (Suav tus qauv)?

16MnDR (GB 3531): Kev ntsuas cuam tshuam ntawm -40 degree, tawm lub zog ntau dua lossis sib npaug rau 315MPa, tsim nyog rau cov haujlwm kub hauv tsev;

P275NL1: Kev ntsuam xyuas cuam tshuam ntawm -40 degree, yield zog Ntau dua lossis sib npaug ntawm 275MPa, koom nrog European txheej txheem nrog kev lees paub thoob ntiaj teb siab dua;

P275NL2: Kev sim cuam tshuam ntawm -50 degree, muab qhov zoo dua qhov kub thiab txias dua li 16MnDR, hloov tau mus rau qhov ua haujlwm hnyav dua cryogenic.

Qhov txawv ntawm P275NL1 thiab P275NL2 yog dab tsi?

P275NL1 yog qib qis -kub nrog qhov tsawg kawg nkaus tawm lub zog ntawm 275 MPa. Nws yog qhov tsim nyog tshwj xeeb rau cov ntawv thov uas tsis tshua muaj - qhov kub thiab txias cia thiab kev thauj mus los ntawm cov pa roj thiab kua. P275NL2 zoo ib yam li P275NL1 tab sis muaj kev txhim kho toughness ntawm qhov kub thiab txias.
