A335 P5, P22, P91 Cracking Tubes yog siv rau hauv cov kav hlau, cov khoom siv hluav taws xob thiab cov kav dej sib txuas hauv cov roj av refineries.
A335 qhia txog seamless ferritic alloy steel nominal raj rau kev siv kub, qib P5, P22, P91 thiab lwm yam.
P5 yog ib qho tsis tshua muaj carbon chromium-molybdenum alloy steel nrog zoo toughness thiab weldability. Nws muaj lub zog tensile yam tsawg kawg nkaus ntawm 586 MPa (85 ksi) ntawm chav tsev kub thiab zoo ductility vim nws cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug rau 0.20%). Tsis tas li ntawd, nws muaj kev cuam tshuam zoo txawm tias qhov kub thiab txias (-150 degree F). Tsis tas li ntawd, cov hlau no tuaj yeem ua kom tawv nqaij los ntawm cov txheej txheem tempering, uas ntxiv dag zog rau nws lub zog thiab hnav tsis kam.
P22 yog chromium-molybdenum tshav kub-resistant steel, nws lub koom haum metallurgical yog bainite + ferrite organisation, nyob rau hauv cov txheej txheem vuam
Hardenability nyob rau hauv cov txheej txheem vuam, yooj yim los tsim cov kab nrib pleb txias, kub tawg, reheat tawg thiab lwm yam vuam tsis xws luag.
P91 yog martensitic tshav kub-resistant steel, tsis tsuas yog muaj kev tiv thaiv siab rau oxidation thiab kub kub chav corrosion kuj, tab sis kuj muaj kev cuam tshuam zoo toughness thiab siab thiab ruaj khov ntev plasticity thiab tshav kub zog zog.
Hauv kev siv kub hauv qab 620C, nws qhov kev tso cai muaj kev ntxhov siab siab dua li austenitic stainless hlau; saum toj no 550C, qhov pom zoo tsim kev tso cai kev ntxhov siab yog li ob zaug ntau npaum li P9 thiab 2.25Cr-1Mo steel.
Thaum P91 alloy yeeb nkab yog welded yam tsis muaj preheating tej yam kev mob, lub sij hawm ntawm cracking yog 100%. Nws tuaj yeem hais tau tias P91 alloy steel yeeb nkab muaj qhov ua kom txias txias ntau dua, feem ntau ntseeg tau tias thaum qhov kub thiab txias tau nce mus rau 200-250C, nws tuaj yeem tiv thaiv qhov txias txias.
A335 P5 thiab P22 nrog rau P91 muaj qhov kub thiab txias thiab tuaj yeem siv ua cov kav dej tawg.
GNEE Group tshwj xeeb hauv kev tsim cov A335 P5 Petroleum Cracking Pipe, A335 P22 Petroleum Cracking Pipe, A335 P91 Petroleum Cracking Pipe, yog tias koj xav tau, thov qhia rau peb tam sim.
