Welding ntawm Clad Steel Phaj
Vuam Yam ntxwv ntawm Austenitic Clad Steel Phaj
Austenitic clad steel daim hlau xa mus rau cov uas muaj austenitic steel cladding txheej thiab pearlitic steel puag txheej. Lub vuam yam ntxwv ntawm xws li steels yog raws li nram no:
① Muaj qhov sib txawv tseem ceeb ntawm lub hauv paus txheej, cladding txheej txheej hlau, thiab cov khoom siv vuam, ua rau muaj zog dilution nyhuv, uas ua rau muaj kev sib tw ntawm solidification cracking.
② Martensite qauv yuav tsim nyob rau hauv fusion zone, ua rau kom muaj zog hardness thiab brittleness.
③ Cov ntsiab lus chromium sib txawv heev ntawm lub hauv paus txheej thiab txheej cladding, txhawb cov pa roj carbon tsiv mus rau txheej cladding thiab exacerbating lub embrittlement ntawm fusion cheeb tsam thiab softening ntawm tshav kub - cuam tshuam cheeb tsam ntawm lwm sab.
Vuam Yam ntxwv ntawm Ferritic-Martensitic Clad Steel Phaj
Ferritic-Martensitic clad steel daim hlau xa mus rau cov uas muaj ferritic-martensitic steel cladding txheej thiab pearlitic steel puag txheej. Lawv cov yam ntxwv vuam zoo ib yam li cov austenitic clad steel daim hlau. Tsis tas li ntawd, lub sij hawm incubation rau txias cracking nyob rau hauv xws li clad steel daim hlau yog ze ze rau cov khoom muab tub lim thiab vuam txheej txheem. Yog li ntawd, kev soj ntsuam vuam tsis tuaj yeem ua tam sim tom qab vuam.
Executive Standards thiab Parameters
Cladding txheej txheem: tawg vuam (feem ntau yog siv, haum rau loj thickness) los yog kub- dov cladding (tsim rau nyias specifications);
Cov qauv: GB / T 24511 (Tuam Tshoj), ASME SA266 (USA), EN 10025 (EU);
Tej Thickness Combinations: Base txheej 6-100mm + Cladding txheej 2-8mm (tag nrho thickness 8-108mm);
Corrosion Resistance Tests: Kev ntsuam xyuas ntsev tsuag (tsis muaj xeb liab tom qab 1000 teev ntawm cov tshuaj ntsev nruab nrab), intergranular corrosion test (raws li ASTM A262 Method E);
Vuam Requirements: Tsawg- carbon steel vuam cov ntaub ntawv (piv txwv li, E7018) rau lub hauv paus txheej, stainless hlau vuam cov ntaub ntawv (xws li, E410) rau txheej cladding, thiab interpass kub yuav tsum tau tswj ntawm tsawg tshaj li los yog sib npaug rau 150℃.
Muaj feem xyuam rau LNG cia / tsheb thauj mus los systems hauv lub zog sector, txais yuav clad steel daim hlau xws li P265GH+410 Clad steel (rau qis-kub toughness) los yog A537CL1+304L Clad steel. Yog tias koj xav txheeb xyuas -162℃cuam tshuam kev ua tau zoo, lub tshuab nqus tsev rwb thaiv tsev sib raug zoo, lossis kho qhov tshwj xeeb rau LNG tso tsheb hlau luam loj, tiv tauj peb kom tau txais cov kev ntsuas thiab cov lus qhia ceev.
