I-ASTM A192:Ukucaciswa Okujwayelekile Kwamashubhu Abilayo Ensimbi Yensimbi Yekhabhoni Yesevisi Yokucindezela Okuphezulu.
Lokhu kucaciswa kuhlanganisa ukujiya kodonga oluncane, ibhoyela yensimbi engenamthungo, namashubhu okushisa aphezulu esevisi enengcindezi ephezulu.
Izinkinobho Zokuzulazula
I-ASTM A192 Ubukhulu Ububanzi
Ngaphandle Ububanzi: 12.7-177.8mm [1/2-7 phakathi.]
Ubukhulu obuncane bodonga:2.2-25.4mm [0.085 -1in.]
Amashubhu anobunye ubukhulu angase anikezwe, inqobo nje uma lawo mashubhu ethobela zonke ezinye izimfuneko zalokhu kucaciswa.
Ukukhiqiza
Amashubhu ngeke abe nekhono futhi ashise noma abandayo asetshenziswe njengokucutshungulwa okucacisiwe.
I-ASTM A192 yizindlela ezimbili eziyinhloko zokukhiqiza zamapayipi ensimbi angenamthungo: abandayo adonswayo futhi ashiswe ashiswe.
Ukwelashwa Kokushisa
Ukushisa kwelashwa ku-1200℉ [650℃] noma ngaphezulu ngemva kokumunca okokugcina okubandayo.
I-Dimensional Tolerances
Izinto ezinikeziwe zizohlangabezana nezidingo ezisebenzayo ze-ASTM A450.

Izinto Ezibalulekile Zokumaka
Izomakwa ngokucacile:
igama lomkhiqizi noma umkhiqizo
inombolo yokucaciswa,ibanga
igama nenombolo ye-oda yomthengi
kushisa noma kubanda.
Qaphela: Ukumaka akufanele kufake idethi yonyaka yalokhu kucaciswa.
Okwamashubhu angaphansi kuka-11/4ngaphakathi. [31.8 mm] ububanzi namashubhu angaphansi kwamamitha amathathu ubude, ulwazi oludingekayo lungase luphawulwe umaka onamathiselwe ngokuvikelekile kunqwaba noma ebhokisini okuthunyelwa kulo amashubhu.
Ukucutshungulwa Okungeziwe
Lapho uthenga futhi usebenzisa ipayipi le-ASTM A192, indawo yokusetshenziswa kokugcina kanye nezidingo ezithile zomsebenzisi zingadinga ukucutshungulwa okwengeziwe:
Paint noma Coating
Upende ongagqwali noma ezinye izinto zokuzivikela zingasetshenziswa phezulu.Lezi zembatho zinikeza ukuvikeleka okuthile ekugqwaleni, ikakhulukazi uma ishubhu lebhayela lichayeka kumswakama.
Imithi elwa nokugqwala
Ngaphezu kokudweba, ezinye izindlela zokwelapha zokunqanda ukugqwala okufana nokufaka i-galvanizing, i-aluminizing, noma ukumbozwa ngezinye izinto ezilwa nokugqwala kungase kusetshenziswe ukusiza ukwandisa ukuqina kweshubhu ezindaweni ezinokhahlo.
Ukwelashwa Kokushisa
Nakuba i-ASTM A192 icacisa izidingo zokwenziwa nokuhlolwa kwepayipi, kwezinye izinhlelo zokusebenza zokwelapha ukushisa okwengeziwe (isb., ukujwayela, ukuhlanganisa) kungase kudingeke ukuze kuzuzwe izici ezithile zemishini noma ukuthuthukisa isakhiwo esincane sepayipi.
I-Surface Yangaphakathi Nangaphandle Iyaphela
Indawo yangaphakathi nengaphandle yamashubhu obhayela kungase kudingeke ukuthi igaywe, iphuculwe, noma ihlanzwe ukuze kuthuthukiswe izici zokugeleza koketshezi noma ukuhlanzeka.
Qeda ukwenza imishini
Ngokuya ngezidingo zokufakwa nokuxhumeka, iziphetho zamashubhu obhayela zingadinga ukucutshungulwa, kushaywe, noma kwenziwe ngomshini ukuze kube lula ukufakwa.
Ukuhlola Okwengeziwe
Ukuqinisekisa ukuthi amashubhu ahlangabezana ne-ASTM A192 kanye nezidingo eziqondene nekhasimende, ukuhlolwa okwengeziwe kungenziwa.Isibonelo, ukuhlolwa kwe-ultrasonic, ukuhlolwa kwe-X-ray, njll.
Isicelo Esiqondile
Isebenza ngokukhethekile kubhayela wensimbi engenamthungo kanye namashubhu okushisa aphezulu.Lawa mashubhu asetshenziselwa ikakhulukazi izinsizakalo zokucindezela okuphezulu njengama-boilers anengcindezi ephezulu, ama-boilers we-ultra-high-pressure, nemishini esebenza ezindaweni ezishisa kakhulu nezinomfutho ophezulu.
Okulandelayo ukusetshenziswa kwepayipi lensimbi le-ASTM A192 ekusebenzeni:
Ama-boilers anengcindezi ephezulu
Amashubhu angenamthungo e-ASTM A192 afaneleka ngokukhethekile ukukhiqiza amashubhu okushisa aphezulu, amashubhu abhayela amanzi ashisayo, amapayipi omusi, amashubhu amakhulu, njll., kuma-boiler amashubhu amanzi anomfutho ophezulu nangaphezulu.Okuvame ukusetshenziswa eziteshini zamandla, izitshalo zezimboni kanye nezimayini kanye nemishini yamakhemikhali, esetshenziselwa ukukhiqiza izinga lokushisa eliphezulu kanye nomusi womfutho ophezulu.
Ama-boilers we-Ultra-high-pressure
Amashubhu e-ASTM A192 asetshenziswa kakhulu ku-ultra-high-pressure (imvamisa ebizwa ngokuthi ama-boilers anengcindezi yokusebenza engaphezu kuka-9.8 MPa) izinhlelo zokusebenza.Lawa ma-boilers ngokuvamile asetshenziswa eziteshini ezinkulu zikagesi.
Ama-Superheaters nama-reheaters
Lezi yizici ezibalulekile ze-boiler futhi zisetshenziselwa ukwandisa izinga lokushisa le-steam, okubuye kwandise ukusebenza kahle kokushisa kwalo lonke uhlelo.
Izishintshi zokushisa
Nakuba i-ASTM A192 ngokuyinhloko isetshenziselwa amashubhu okubhayela, ingasetshenziswa futhi ekushintshaniseni ukushisa lapho izakhiwo ezinhle zokudlulisa ukushisa zidingeka, ikakhulukazi endaweni yokushisa ephezulu, enengcindezi ephezulu.
Ama-Boiler Amafutha Ashisayo
Kulolu hlobo lwe-boiler, amandla ashisayo adluliswa ngokushisa uwoyela oshisayo, ovame ukusetshenziswa ezimbonini zamakhemikhali, zokucubungula ukudla nezindwangu.I-astm a192 tubing ifanele izinga lokushisa eliphezulu, izimo zengcindezi ephezulu ezitholakala kulezi zinhlelo zokusebenza.
Amazinga Abalulekile
I-ASTM A192: Kumashubhu kabhayela wensimbi engenamthungo wamabhayela anengcindezi ephezulu.
I-ASTM A179: Isishintshi sokushisa sensimbi esithambile esidonswa ngokubanda esingenamthungo kanye namashubhu e-condenser ezimweni zezinga lokushisa eliphansi.
