Khoom lub hauv paus rau phau ntawv
L290 Welded yeeb nkab yog tus cwj pwm los ntawm nws txoj kab uas muaj tuab loj, ua rau nws muaj ib qho ntawm cov yeeb nkab yeeb nkab zoo nkauj rau ntev thiab cov roj tsheb sib nrug ntawm cov kab tsheb. Nws lub zog nruab nrab tau ua kom cov kev xav tau ntawm cov roj thiab cov roj ntsha feem ntau xa cov phiaj xwm. Nws muaj cov txheej txheem weldability zoo, thiab cov kev sib txhuam vuam cov txheej txheem thaum lub sij hawm ntawm {}}, ua rau nws yooj yim kom ntseeg tau weld zoo. Piv rau PSL2 lossis qib siab dua cov kav dej steel, tus nqi ntau lawm thiab tus nqi sib tw ntau dua.
Parameter rooj
PSL1 muaj cov kev cai nyob hauv qab, feem ntau hais txog tsuas yog qhov siab tshaj plaws carbon sib npaug (CEQ) thiab siab tshaj plaws cov ntsiab lus carbon thiab siab tshaj plaws kom ntseeg tau weldability. Ib txwm muaj tshuaj lom neeg ntau npaum li cas rau l290 PSL1 yog raws li hauv qab no.
| Cov pa roj carbon (C | Tsawg dua los yog sib npaug rau 0.22% |
| Manganese (mn) | Tsawg dua los yog sib npaug rau 1.20% |
| Phosphorus (p) | Tsawg dua los yog sib npaug rau 0.025% |
| Sulphur (s) | Tsawg dua los yog sib npaug rau 0.015% |
| Carbon sib npaug (CEQ) | Feem ntau yuav tsum tau tsawg dua lossis sib npaug rau 0.36%- 0.40}}}}}}}}}}}}}. |
Kev Kho Cua Sov
GB / T 9711 PSL1 L290 LSAWW STIRS PIPES, TAB TAS NRHO, Feem ntau yias dhau ib txwm ua raws li lawv txoj kev kho cua sov tag nrho. Tus txheej txheem no uniformly warts cov yeeb nkab steel rau qhov ntsuas kub ntawm lub hauv paus, feem ntau yog 880 qib Tus txheej txheem no lub hom phiaj tshem tawm Post - kev hloov pauv micrerture, kom ua kom tau cov khoom sib xyaw ua kom tau raws li cov khoom siv tshuab hluav taws xob, kom ua kom tau cov khoom siv tshuab hluav taws xob, kom ua kom tau cov khoom siv tshuab hluav taws xob kom ua tau zoo rau cov kev ua kom tau zoo thiab kev sib raug zoo.
