API 5L Standard Common Terms

1 Qhov Tsis Zoo: Nws yog qhov tsis xws luag uas nws qhov loj me thiab / lossis qhov sib faib ntom ntom tshaj qhov kev lees paub tau teev tseg hauv tus qauv.
2 Qhov tsis zoo: Nws yog qhov tsis sib xws lossis qhov tsis sib xws hauv cov phab ntsa tuab lossis ntawm qhov chaw ntawm cov khoom kuaj pom los ntawm txoj kev tshuaj xyuas tau piav qhia hauv tus qauv.
3 Delamination: Cov txheej txheem tsim los ntawm kev sib cais ntawm cov hlau sab hauv feem ntau yog sib npaug rau saum npoo ntawm cov yeeb nkab steel.
4 Cov yeeb nkab lub cev: Rau cov kav hlau welded, nws hais txog tag nrho cov yeeb nkab steel tsis suav nrog thaj tsam vuam thiab cua sov.
5 Cov yeeb nkab kawg: Nws suav nrog cov yeeb nkab steel hauv 100mm ntawm txhua qhov kawg ntawm cov yeeb nkab steel.
6 Kev tsis zoo: Lub radial offset ntawm cov npoo ntawm steel sawb / steel phaj.
7 Cold forming: Cov txheej txheem ntawm kev tsim steel sawb lossis steel phaj rau hauv cov yeeb nkab steel tsis muaj cua sov.
8 steel yeeb nkab qib: Lub npe qhia lub zog ntawm cov yeeb nkab steel. Tib yam li qib steel (steel lub npe lossis hom).
9 Kev Pabcuam Kev Pabcuam: Cov xwm txheej ntawm kev siv tau teev tseg los ntawm tus neeg yuav khoom hauv daim ntawv cog lus (sib faib rau cov kev pabcuam uas tsis yog acidic lossis tsis yog ntug dej hiav txwv, acidic thiab / lossis kev pabcuam offshore).
10 Cov txheej txheem yuav tsum tau ua pov thawj: yog hais txog kev ua haujlwm kawg hauv cov txheej txheem steel yeeb nkab uas cuam tshuam rau cov yam ntxwv ntawm cov khoom kom ua tau raws li cov qauv no (tshwj tsis yog tshuaj lom neeg muaj pes tsawg leeg thiab qhov loj me).
11 Khoom Specification PSL: API5L tus qauv txhais ob theem ntawm cov khoom specification (PSL1 thiab PSL2 qhia cov qauv sib txawv. PSL2 ua cov kev cai rau cov pa roj carbon sib npaug, notch toughness, siab tshaj tawm lub zog, siab tensile zog, yield zog piv, tus me nyuam, thiab lwm yam.
12 Kev xeem batch: ib qho tshwj xeeb ntawm cov kav hlau steel nrog tib lub kab uas hla sab nraud thiab phab ntsa tuab ua los ntawm tib lub cub tawg batch nyob rau hauv tib lub steel yeeb nkab raug mob thiab los ntawm tib cov yeeb nkab ua txheej txheem.
13 Cov khoom lag luam tsom xam: tshuaj ntsuam xyuas cov yeeb nkab steel, qib steel, thiab steel strips.
14 Cov cuab yeej calibration: kev ua haujlwm ntawm kev kho cov cuab yeej ntsuas tsis muaj kev puas tsuaj rau tus nqi siv tau teev tseg.
15 Undercut: grooves thiab underfills tsim los ntawm weld hlau ntawm cov khoom niam txiv uas nyob ib sab ntawm cov ntiv taw weld.
