I-ASTM A106 ne-ASTM A53 zisetshenziswa kabanzi njengezindinganiso ezivamile zokwenziwa kwepayipi lensimbi ye-carbon.
Nakuba amashubhu ensimbi e-ASTM A53 kanye ne-ASTM A106 eshintshana kwezinye izinhlelo zokusebenza zezimboni, izakhiwo zawo ezihlukene zenza ukukhetha okufanele kwamashubhu amisiwe kubaluleke kakhulu ezindaweni ezithile nezimo ezithile.
Izinkinobho Zokuzulazula
Uhlobo Lwepayipi
Ipayipi lensimbi le-ASTM A53 libandakanya ipayipi lensimbi elishiselwe futhi elingenamthungo.
I-ASTM A106 ihlanganisa kuphela ipayipi lensimbi elingenamthungo.
| Okujwayelekile | Ububanzi | Izinhlobo | Ibanga | |
| I-ASTM A106: Ipayipi Lensimbi Lekhabhoni Elingenamthungo Yesevisi Yezinga Lokushisa Eliphezulu | I-NPS 1/8 - 48 in (DN 6 -1200mm) | Ipayipi Lensimbi Le-Carbon Elingenamthungo | A, B, kanye no-C | |
| I-ASTM A53: Imnyama futhi Iyashisa, Ifakwe Zinc, Ishiselwe futhi Ayinamthungo | I-NPS 1/8 - 26 in (DN 6 -650mm) | uhlobo S: Ayinamthungo | U-A kanye no-B | |
| uhlobo F: Isithando somlilo-izinqe-ezishiselwe, ezishiselwe ngokuqhubekayo | U-A kanye no-B | |||
| uhlobo E: Ukumelana nogesi-okushiselwe | U-A kanye no-B | |||
| Qaphela: Womabili amazinga avumela ukuhlinzekwa kwepayipi elinobunye ubukhulu inqobo nje uma lihlangabezana nazo zonke ezinye izidingo zekhodi. | ||||
Izidingo Zokwelashwa Kokushisa
I-ASTM A106
Kumelwe iphathwe ngokushisa, ngokuvamile ngokujwayela (inqubo yokushisisa ngaphezu kwezinga lokushisa elibalulekile bese ipholisa izinga lokushisa elimaphakathi).
Ipayipi eligoqiwe elishisayo: alidingi ukwelashwa kokushisa.Uma ipayipi eligoqiwe elishisayo liphathwa ngokushisa, lizophathwa ngokushisa ku-1200 °F [650 °C] noma ngaphezulu.
Ipayipi elidonswa ngokubanda: lizophathwa ngokushisisa ku-1200 °F [650 °C] noma ngaphezulu ngemva kwenqubo yokugcina yokudweba okubandayo.
I-ASTM A53
Uhlobo E, Ibanga B, Nohlobo F, IBanga B: luzophathwa ngokushisa ngemva kokushiselwa okungenani lube ngu-1000 °F [540°C] ukuze kungabikho i-martensite engavunyelwe ekhona, noma iphathwe ngenye indlela ukuze kungabi khona i-martensite engapheli.
Uhlobo S: Ukwelashwa kokushisa akudingekile kumapayipi angenamthungo.
Izingxenye Zekhemikhali
Lapho kuhlaziywa ukwakheka kwamakhemikhali kwe-ASTM A53 kanye neshubhu ye-ASTM A106, umehluko omkhulu obalulekile ungaqashelwa.I-ASTM A106 icacisa okuqukethwe kwe-silicon (Si) okungengaphansi kuka-0.10%, okunomthelela ekusebenzeni kwayo emazingeni okushisa aphakeme, okuyenza ifaneleke ikakhulukazi ukusetshenziswa ezindaweni ezinezinga lokushisa eliphezulu njengalezo ezisembonini ye-petrochemical kanye nezinhlelo zokuhambisa isitimu.
Kokuqukethwe kwekhabhoni (C), izinga le-ASTM A53 licacisa umkhawulo ongaphezulu ophansi, ikakhulukazi kumabanga A no-B oHlobo S noHlobo E. Lokhu kwenza amashubhu oHlobo lwe-A53 afaneleke kakhulu ekushiseleni nasekusebenzeni okubandayo ngakho-ke avame ukusetshenziswa ekwakheni nasemanzini. izinhlelo zokuhamba, njengamapayipi amanzi negesi.
Mayelana nokuqukethwe kwe-manganese (Mn), i-ASTM A106 ihlinzeka ngebanga elibanzi leBanga B kanye no-C, elivumela ukuguquguquka okuthuthukisiwe enqubweni yokukhiqiza ngenkathi kuthuthukiswa amandla.Ngakolunye uhlangothi, ipayipi le-A53 lilinganiselwe emkhawulweni ongaphezulu oqinile wokuqukethwe kwe-manganese, okwenza kube lula ukuzinza ngesikhathi sokushisela.

Izinhlelo zokusebenza
Izidingo zokuklama nokukhiqiza ze-ASTM A53 kanye nepayipi lensimbi le-ASTM A106 zibonakalisa izimo ezihlukile zohlelo lokusebenza zazo.
Ipayipi lensimbi le-ASTM A53ivamise ukusetshenziswa ekwakhiweni nasezakhiweni zemishini nasezindaweni ezinengcindezi encane yokuthutha uketshezi noma amagesi, njengamanzi kamasipala kanye negesi yemvelo.
Amashubhu ensimbi e-ASTM A106asetshenziswa kakhulu ezinhlelweni ezingaphansi kwezindawo ezishisa kakhulu, njengakumabhayela ezitshalweni ze-petrochemical kanye neziteshi zikagesi ukuthutha isitimu esinezinga lokushisa eliphezulu noma uwoyela oshisayo.Amandla aphezulu okudonsa kanye nesivuno abawanikezayo aqinisekisa ukusebenza nokuqina ngaphansi kwezimo ezinzima, ikakhulukazi kumashubhu ensimbi e-A106 Grade C, anikeza isici sokuphepha esiphezulu endaweni yokushisa ephezulu kanye nengcindezi ephezulu.
