1. ** Yog A53b Yeeb Nkab Seamless? **
>ASTM A53B hais txog ib qho tshwj xeeb ** Cov Khoom Siv Khoom ** (Qib B) tsis pub dhau A53 qhov tshwj xeeb. A53 cov yeeb nkab los hauv peb ** hom **: hom s (seamless), hom E (hluav taws xob} E6 4} Entw), thiab hom F (rauv welded). Yog li, cov yeeb nkab A53b * tuaj yeem * yog seamless yog tias nws tau xaiv raws li ** A53 qib B, hom S **. Nws kuj tseem tuaj yeem welded (hom e lossis f).
2. ** Dab tsi yog qhov txawv ntawm A53 ERW thiab A106? **
>* ** A53 ERW (hom E): ** Tus yeeb nkab tsim siv cov hluav taws xob ua haujlwm vuam. Nws feem ntau yog siv rau cov ntawv thov siab dua xws li cov kav dej, tua hluav taws, thiab qee qhov qis- siab {cov txheej txheem kev ua haujlwm. Nws los nyob rau qib ib lossis B.
>* ** A106: ** Qhov kev qhia tshwj xeeb no tshwj xeeb rau ** Nws feem ntau muaj cov txheej txheem stricter thiab cov neeg kho tshuab ib zaug li A53, tshwj xeeb tshaj yog rau nce qib siab. Nws los rau qib A, B, lossis C (qib B feem ntau yog).
3. ** Yog A106 seamless lossis welded? **
>ASTM A106 yeeb nkab yog ** tsuas yog seamless **. Welded yeeb nkab tsis pub rau hauv qab no specification.
4. ** Dab tsi yog qhov txawv ntawm PIB4710 thiab PE3408? **
>* ** PE3408: ** Qhov no yog cov laus tsim rau hypehlore (HDB) ntawm 1600 psi (11.0 MPa) ntawm 73℃F (23 qib) rau dej. Nws sawv cev rau theem kev ua tau zoo.
>* ** PIB4710: ** Qhov no yog ib qho tshiab dua, siab dua-}} Performance cov khoom tsim HDPE. Nws muaj ntau dua Mrs ntawm 4700 psi (32.3 MPa) thiab qib siab dua ntawm 2150 psi (14.8 MPa) ntawm 73℃f (23 degree) rau dej. Qhov no txhais tau tias PE4710 tau zoo dua ntev {}} Cov kabmob lub siab- kev ntaus nqi piv rau PE3408, lossis cov kev ntsuas siab dua ntawm tib phab ntsa tuab.
5. ** Dab tsi yog qhov txawv ntawm A53 thiab A500 Yeeb Nkab? **
>* ** A53: ** DAIM NTAWV CEEB TOOM ZOO ** Welded Steel Yeeb Nkab Yog Qhov Kev Ntsuam Xyuas Qhov Twg, Cov Khaub Ncaws Hnav, Chav, Huab Cua). Nws yog tsim nyob rau hauv cov duab sib dhos nkaus xwb. Kev soj ntsuam feem ntau suav nrog hydrostatic lossis tsis - kev ntsuas hluav taws xob cuam tshuam.
>* ** A500: ** DAIM NTAWV QHIA TXOG ** txias {{{} Tsim welded thiab seamless carbon hlau tubing ** Hauv kev sib tw thiab ntau yam duab, duab plaub, thiab lwm yam). Nws tau tsim rau ** cov ntawv thov qauv "zoo li cov thav duab ua, txhawb nqa cov tshuab muaj zog, tab sis siab} nruj yog feem ntau * tsis yog * ib qho yuav tsum tau ua. Kev xeem tsom rau cov khoom siv me me (tensile, tawm lub zog) thiab lub zog ntev.
