API 5L PSL2LSAW steel yeeb nkab
LSAW steel yeeb nkab yog tsim los ntawm cov hlau hauv tsev tsim thiab smelted nyob rau hauv lub cub hluav taws xob, kho nrog hluavtaws slags thiab nrum los ntawm nruam casters.Cov txheej txheem siv hlau ua kom ntseeg tau tias kev ua tiav ntawm cov tshuaj ntshiab hlau nrog kev siv cov sulfur thiab phosphor cov ntsiab lus muab siab tensile, ductility thiab corrosion kuj zog ntawm cov kav dej yuav tsum tau ua nyob rau hauv qis kub nyob rau hauv ntau yam corrosion media.
Rolling siv lub xovxwm piercing zeb thiab nruam zeb nruab nrog ib tug taag mandrel tso cai nruj me ntsis ntsuas tolerances yuav tsum tau thiab xyuas kom meej tsis muaj cov yeeb nkab lub cev thiab nto defects.
Txhawm rau kom ua tiav siab tensile thiab ductility steel nrog rau nws cov qauv xav tau, muab kev tiv thaiv corrosion siab nyob rau hauv ntau yam kev tshaj tawm corrosion, cov kav dej tau kho cua sov hauv lub tshuab computer taug kev nqaj.70% ntawm cov kav dej yog raug rau kev kho cua sov.
Cov kav dej raug tshuaj xyuas rau sab hauv thiab sab nraud ntws los ntawm kev ntsuas tsis siv neeg tsis zoo ntawm kev tshuaj xyuas ultrasonic thiab electromagnetic.Cov yeeb nkab xaus kev tshuaj xyuas tom qab beveling yog ua los ntawm kev sib nqus-fluoroscopic flaw detection.
Thaum tsim cov kav dej seamless kom kuaj xyuas cov khoom tiv thaiv corrosion los ntawm hydrogen suav nrog kev sib tsoo raws li NACE MR 02-84 thiab sulphide stress corrosion cracking method raws li NACE MR 01-77.
npi 5 l grseamless yeeb nkab
Lub hom phiaj ntawm api 5l gr.b seamless yeeb nkab yog tsim rau siv nyob rau hauv conveying gas, dej, thiab roj nyob rau hauv ob qho tib si roj thiab natural gas industries.
