ASTM A234 WP5 yog chromium-molybdenum alloy hlau uas yog tsim los kom muaj zog thiab corrosion-resistant nyob rau hauv high-temperature. Cov hlau no muaj xws li tsawg kawg yog 4 feem pua chromium thiab 0.45 feem pua molybdenum, uas muab tshwj xeeb tiv thaiv oxidation thiab kub-kub corrosion. Tsis tas li ntawd, ASTM A234 WP5 muaj cov lej ntawm lwm cov ntsiab lus xws li manganese, silicon, thiab carbon, uas txhim kho cov hlau cov khoom siv kho tshuab.
Lub luj tshib 180 degree ua los ntawm ASTM A234 WP5 yog cov yeeb nkab haum uas siv los txuas ob lub kav dej ntawm tib qhov loj tab sis nrog cov lus qhia sib txawv. Qhov kev haum no tseem hu ua lub luj tshib rov qab los yog U-khoov. Qhov nkhaus ntawm lub luj tshib 180 degree tso cai rau cov kua dej los yog cov pa roj ntws tawm ntawm cov yeeb nkab. Qhov no yog qhov tseem ceeb hauv cov xwm txheej uas cov dej ntws los yog roj yuav tsum tau tswj kom tsis muaj kev cuam tshuam lossis muaj kev kub ntxhov.
Thaum xaiv ASTM A234 WP5 180 degree luj tshib, muaj ntau yam los xav txog. Thawj qhov kev txiav txim siab yog cov yeeb nkab loj. Lub luj tshib xaiv yuav tsum yog tib yam li cov yeeb nkab uas nws haum. Tsis tas li ntawd, lub luj tshib lub thickness yuav tsum raug txiav txim siab los xyuas kom meej tias nws tuaj yeem tiv taus lub siab thiab kub ntawm cov kua los yog roj los ntawm cov yeeb nkab. Lub vojvoog ntawm lub luj tshib yog lwm qhov tseem ceeb uas yuav tsum xav txog. Lub vojvoog ntawm lub luj tshib txhais qhov khoov qhov nkhaus thiab cuam tshuam cov dej ntws los yog roj los ntawm cov yeeb nkab. Lub luj tshib loj dua tsis tshua muaj peev xwm ua kom muaj kev kub ntxhov lossis kev poob siab hauv lub cev. Txawm li cas los xij, lawv kuj siv ntau qhov chaw thiab tej zaum yuav tsis haum rau kev teeb tsa uas qhov chaw txwv.

180 degree ASTM A234 WP5 Luj tshib tuaj yeem ua tau ntau yam, suav nrog forged, cam khwb cia, thiab seamless. Seamless ntau lawm yog txoj kev nquag tshaj plaws vim nws tsim cov khoom zoo nrog cov tuab tuab thiab lub zog. Forging yog lwm txoj hauv kev tsim lub luj tshib uas muab lub zog ntau dua thiab tiv thaiv corrosion. ASTM A234 WP5 180 degree Luj tshib tuaj yeem coated nrog ntau yam khoom siv los txhim kho corrosion kuj. Epoxy yog txheej txheej txheem uas muab kev tiv thaiv zoo tiv thaiv corrosion thiab hnav. Polyethylene thiab zinc yog ob txheej txheej ntxiv uas tuaj yeem ua haujlwm.
