1. Txhais thiab siv
Lus Txhais: L360 pipeline steel yog cov hlau tsis muaj roj carbon tsawg uas ua raws li cov qauv tshwj xeeb (xws li API 5L, GB / T21237, thiab lwm yam) rau kev tsim cov kav dej. Qhov "X" nyob rau hauv nws qib sawv cev rau pipeline steel, thiab "360" sawv cev rau qhov tsawg kawg nkaus yield zog ntawm steel phaj yog 360mpa (6.895Mpa=1ksi), uas yog hais txog 52ksi.
Kev Siv: Feem ntau yog siv rau hauv kev thauj mus los hauv cov kav dej xws li roj thiab cov nkev, thiab tseem tsim nyog rau lwm yam kev thauj mus los xws li cov khoom siv tshuaj lom neeg, dej, thiab lwm yam. Nws lub zog siab, siab toughness, zoo vuam kev ua tau zoo thiab corrosion kuj ua rau nws zoo tagnrho. cov khoom siv rau cov teb no.
2. Cov yam ntxwv tseem ceeb
Lub zog siab: L360 pipeline steel muaj lub zog tensile siab thiab lub zog tawm los, thiab tuaj yeem tiv taus siab thiab tensile quab yuam.
High toughness: Thaum muaj kev kub siab, nws tuaj yeem zam cov kab nrib pleb lossis tawg kom ntseeg tau tias kev ua haujlwm zoo ntawm cov kav dej.
Corrosion kuj: Nyob rau hauv tus txheej txheem ntawm conveying xov xwm, nws muaj peev xwm tiv taus qhov yaig ntawm ntau yam corrosive tshuaj thiab ncua lub neej kev pab cuam ntawm lub raj xa dej.
Zoo weldability: Ntau txoj kev vuam tuaj yeem tau txais cov txiaj ntsig zoo los xyuas kom muaj kev sib khi thiab kev ntseeg siab ntawm cov kav dej.
Kev lag luam zoo: Piv nrog rau lwm cov qib high-qib steels, tus nqi ntawm L360 pipeline steel yog tus nqi qis, uas yog qhov tsim nyog los txo tus nqi ntawm kev tsim cov kav dej.
3. Tshuaj muaj pes tsawg leeg thiab txhua yam khoom
Tshuaj muaj pes tsawg leeg: C cov ntsiab lus Less dua los yog sib npaug rau {{0}}.26% (welding) los yog tsawg tshaj los yog sib npaug rau 0.28% (seamless), Mn ntsiab lus Less dua los yog sib npaug rau 1.40%, P thiab S cov ntsiab lus Tsawg dua lossis sib npaug rau {{10}}.030%, Cu, Ni, Cr cov ntsiab lus Tsawg dua lossis sib npaug li 0.5%, Mo cov ntsiab lus Tsawg dua lossis sib npaug li 0.15%. Tsis tas li ntawd, tag nrho cov ntsiab lus ntawm V, Nb, thiab Ti yuav tsum tsis pub tshaj 0.15%.
Mechanical zog: yield zog Ntau tshaj los yog sib npaug rau 360Mpa, tensile zog Ntau dua los yog sib npaug rau 460Mpa, elongation Ntau tshaj los yog sib npaug rau ib qho nqi (tus nqi tshwj xeeb muaj feem xyuam rau thaj tsam ntawm qhov sib npaug ntawm cov qauv tensile).
IV. Kev tsim khoom thiab tshuaj xyuas
Cov txheej txheem ntau lawm: Kev tsim cov L360 pipeline steel xav tau ntau yam kev sib txuas xws li steelmaking, dov, thiab kev kho cua sov. Ntawm lawv, cov txheej txheem dov suav nrog perforation, raj dov, sizing, straightening thiab lwm cov kauj ruam los xyuas kom meej qhov tseeb qhov tseeb thiab nto zoo ntawm cov yeeb nkab steel.
Kev soj ntsuam cov qauv: L360 pipeline steel yuav tsum ua raws li cov kev cai ntawm cov qauv, xws li API 5L, GB / T21237, thiab lwm yam. Thaum lub sij hawm kev soj ntsuam, cov tshuaj muaj pes tsawg leeg, mechanical zog, seem sib txawv, nto zoo, thiab lwm yam. yuav tsum tau soj ntsuam tag nrho kom ntseeg tau tias nws zoo raws li tus qauv yuav tsum tau.
