"PIB ALLOY STEEL HTASTM A335 GR P22- TSI 80. ASME B36.10 PLAIN ENDS (QUANTITIES UNIT: M)" yog cov txheej txheem kev qhia tshwj xeeb uas piav qhia txog cov kav hlau alloy.

PIPE Alloy STEEL HT:
"PIPE" txhais tau tias cov yeeb nkab, thiab "ALLOY STEEL" txhais tau tias alloy steel. Alloy steel yog cov hlau uas muaj ib lossis ntau lub ntsiab lus alloying (xws li chromium, molybdenum, tungsten, thiab lwm yam) thiab muaj cov khoom zoo xws li kub tsis kam, corrosion kuj thiab lub zog.

"HT" feem ntau yog hais txog qhov kub thiab txias, qhia tias cov yeeb nkab steel no haum rau qhov kub thiab txias.

ASTM A335 GR P22 Cov ntsiab lus:
Qhov no yog ib qho kev piav qhia ntawm tus qauv thiab qib ntawm cov khoom siv yeeb nkab.

ASTM A335 Cov Lus Qhia Tshwj Xeebyog tus qauv tsim los ntawm American Society for Testing and Materials (ASTM) rau seamless alloy steel kav, tshwj xeeb tshaj yog rau cov kub thiab kub siab.
GR P22 yog cov khoom siv tshwj xeeb raws li tus qauv no, qhov "P22" qhia txog cov tshuaj muaj pes tsawg leeg thiab kev ua tau zoo ntawm cov khoom siv yeeb nkab. P22 alloy steel feem ntau muaj chromium (Cr) thiab molybdenum (Mo) cov ntsiab lus, muaj qhov kub thiab txias zog thiab corrosion kuj, thiab haum rau qhov kub thiab txias.
TSI 80:
Qhov no yog hais txog phab ntsa thickness qib ntawm cov yeeb nkab, thiab "SCH" yog cov ntawv luv ntawm "Schedule".

SCH 80 txhais tau hais tias phab ntsa tuab ntawm cov yeeb nkab yog tuab thiab tuaj yeem tiv taus siab sab hauv. Rau SCH 80 cov kav dej, nws cov phab ntsa tuab yog loj dua ntawm cov kav dej ntawm tib txoj kab uas hla, uas tuaj yeem ua rau nws muaj peev xwm ua rau muaj peev xwm thiab cuam tshuam.
ASME B36.10:
Qhov no yog tus qauv tsim los ntawm American Society of Mechanical Engineers (ASME) uas qhia txog qhov loj, zoo li, kam rau ua, qhov hnyav thiab lwm yam kev xav tau ntawm cov kav hlau. B36.10 tshwj xeeb yog lub hom phiaj ntawm sab nraud txoj kab uas hla, phab ntsa thickness thiab lwm yam tsis xws li carbon steel thiab alloy steel seamless kav thiab welded kav los xyuas kom meej tus qauv thiab sib xws ntawm pipeline khoom.

PLAIN xaus:
"Plain Ends" yog hais txog cov kav dej uas tsis muaj machining lossis kev sib txuas xaus, feem ntau nrog cov npoo du. Muab piv rau cov kav dej nrog cov xov los yog flanged sib txuas, cov kav dej tiaj tiaj feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj kev sib txuas welded.

QUANTITIES UNIT: M:
Qhov no qhia tau hais tias chav tsev ntawm kev ntsuas rau cov khoom yog "meter", uas yog, qhov ntau ntawm cov yeeb nkab yog ntsuas hauv meters, tsis yog daim los yog lwm yam units.

Cov yeeb nkab uas tau piav qhia hauv cov lus piav qhia no yog cov yeeb nkab kub kub uas ua tau raws li ASTM A335 GR P22 tus qauv, nrog rau phab ntsa tuab ntawm SCH 80 thiab ua tau raws li ASME B36.10 tus qauv loj. Qhov kawg ntawm cov yeeb nkab yog dawb (tsis muaj xov lossis flanges), qhov ntev yog ntsuas hauv meters, thiab nws yog qhov tsim nyog rau cov kav dej hauv qhov kub thiab txias, siab thiab corrosive ib puag ncig.
