I-ASTM A192 (I-ASME SA192ipayipi lensimbi) liyipayipi lensimbi yekhabhoni elingenamthungo elisetshenziswa ezindaweni ezinokushisa okuphezulu kanye nokucindezela okuphezulu futhi lisetshenziswa kabanzi kuma-boiler kanye nama-heat exchanger.
Ububanzi bangaphandle: 1/2″ – 7″ (12.7 mm – 177.8 mm);
Ubukhulu bodonga: 0.085″ – 1.000″ (2.2 mm – 25.4 mm);
Amanye amasayizi epayipi lensimbi nawo anganikezwa njengoba kudingeka, uma nje zonke ezinye izidingo ze-A192 zihlangatshezwa.
I-ASTM A192 ikhiqizwa kusetshenziswa inqubo engenamthungo futhi iqedwa ngokushisa noma ngokubandayo njengoba kudingeka;
Futhi, ukuhlonza ipayipi lensimbi kufanele kubonise ukuthi ipayipi lensimbi liqediwe ngokushisa noma ngokubandayo.
Ukuqeda okushisayo: Kubhekisele enkambisweni yokuqeda ubukhulu bokugcina bepayipi lensimbi esimweni esishisayo. Ngemva kokuba ipayipi lensimbi selidlule enkambisweni yokucubungula eshisayo njengokugoqa okushisayo noma ukudonsa okushisayo, alicutshungulwa ngokubandayo. Amapayipi ensimbi aqediwe ashisa kakhulu anokuqina okungcono kanye nokuguquguquka kodwa anokubekezelelana okukhulu.
Kuqediwe ukubanda: Ipayipi lensimbi licutshungulwa libe nobukhulu balo bokugcina ngezinqubo zokusebenza ezibandayo njengokugoqa okubandayo noma ukudweba okubandayo ekushiseni kwegumbi. Amapayipi ensimbi aqediwe ngokubandayo anokubekezelelana okunembe kakhulu kanye nezindawo ezibushelelezi kodwa angase alahlekelwe ukuqina okuthile.
Amashubhu ensimbi angenamthungo aqedwe ngokushisa awadingi ukwelashwa ngokushisa.
Amashubhu ensimbi angenamthungo aqedwe ngokubandayo aphathwa ngokushisa emazingeni okushisa angu-650°C noma ngaphezulu ngemva kokwelashwa kokugcina kokubanda.

I-ASTM A192 ayivumeli ukungezwa kwezinye izakhi ekwakhiweni kwamakhemikhali.
| Amandla okudonsa | Amandla okukhiqiza | Ukwelulwa | Ukuhlolwa Kokuthamba | Ukuhlolwa Kokuvutha |

Ngaphandle kokuthi kuchazwe ngenye indlela ku-ASTM A192, izinto ezinikezwe ngaphansi kwale ncazelo kufanele zihambisane nezidingo ezifanele zeI-ASTM A450/A450M.
Ukuqina kweRockwell: 77HRBW.
Kwamapayipi ensimbi anobukhulu bodonga obungaphansi kuka-0.2" [5.1 mm].
Ukuqina kukaBrinell: 137HBW.
Ubukhulu bodonga lwepayipi lensimbi obungu-0.2" [5.1 mm] noma ngaphezulu.
Ukuze uthole izidingo ezithile zokusebenza, bheka i-ASTM A450, Into 23.
· Imvamisa: Ipayipi ngalinye lensimbi lihlolwa ngengcindezi ye-hydrostatic.
· Isikhathi: Gcina ingcindezi encane okungenani imizuzwana emi-5.
· Inani lokucindezela kwamanzi: Libalwa kusetshenziswa ifomula elandelayo. Qaphela iyunithi.
Amayunithi e-Inch - Pound: P = 32000 t/D
Amayunithi e-SI: P = 220.6t/D
P = ingcindezi yokuhlola ye-hydrostatic, i-psi noma i-MPa;
t = ubukhulu bodonga obucacisiwe, ngo. noma mm;
D = ububanzi obungaphandle obucacisiwe, ngaphakathi noma mm.
· Umphumela: Uma kungekho ukuvuza emapayipini, ukuhlolwa kubhekwa njengokuphumelele.
Okunye okungenziwa esikhundleni sokuhlolwa kwe-hydrostatic kungenzeka ngokuhlolwa okufanele okungabhubhisi.
Noma kunjalo, indinganiso ayisho ukuthi iyiphi indlela yokuhlola engonakalisi engasetshenziswa.
Amapayipi uma efakwa kubhoyila kufanele ame anwebeke futhi abe nobuhlalu ngaphandle kokubonisa imifantu noma amaphutha. Amapayipi e-Superheater uma esetshenziswa kahle kufanele ame yonke imisebenzi yokwakha, ukushisela, kanye nokugoba edingekayo ekusetshenzisweni ngaphandle kokukhula kwamaphutha.
Insimbi yeBotopingumkhiqizi wepayipi lensimbi yekhabhoni elishiselwe ngekhwalithi ephezulu kanye nomhlinzeki ovela eShayina, futhi ingumthengisi wepayipi lensimbi elingenamthungo, ikunikeza izixazululo eziningi zamapayipi ensimbi!
Xhumana nathiukuze uthole ikhotheshini evela kumthengisi wepayipi lensimbi engenamthungo waseShayina.
