I-ASTM A210 Ibanga C (Ibanga C le-ASME SA210) iyipayipi lensimbi elingenamthungo eliphakathi nendawo elenzelwe ngqo ukusetshenziswa ekwakhiweni kwamapayipi ebhoyila kanye namapayipi ebhoyila, okuhlanganisa iziphetho zokuphepha, udonga lwesithando kanye namapayipi okusekela, kanye namapayipi e-superheater.
Ibanga C linezakhiwo ezinhle zomshini, elinamandla okudonseka angu-485 MPa kanye namandla okukhiqiza angu-275 MPa. Lezi zakhiwo, kanye nokwakheka kwamakhemikhali okufanele, zenza amashubhu ebanga C e-ASTM A210 afaneleke kahle ukusetshenziswa ezindaweni ezinokushisa okuphezulu kanye nokucindezela okuphezulu futhi akwazi ukumelana nezingcindezi ezibangelwa ukusebenza kwebhoyila.
Amapayipi kumele enziwe ngenqubo engenamthungo futhi kufanele aqedwe ngokushisa noma ngokubandayo.
Ngezansi ishadi lokugeleza kwenqubo yokukhiqiza ipayipi lensimbi elingenamthungo eliqediwe ngokubandayo:
Ngakho-ke uyini umehluko phakathi kwepayipi lensimbi elingenamthungo eliqediwe ngokushisa kanye nepayipi lensimbi eliqediwe ngokushisa eliqediwe ngokushisa futhi ukhetha kanjani?
Kuqediwe ngokushisaipayipi lensimbi elingenamthungo liyipayipi lensimbi eligoqwa noma elibhobozwa ekushiseni okuphezulu nakwezinye izinqubo bese lipholiswa ngqo ekushiseni kwegumbi. Amapayipi ensimbi akulesi simo avame ukuba nokuqina okungcono namandla athile, kodwa ikhwalithi yobuso ingase ingabi mihle njengamapayipi ensimbi aqediwe kubanda ngoba inqubo yokwelapha ukushisa ingaholela ekushiseni noma ekukhishweni kwekhabhoni kobuso bepayipi lensimbi.
Kuqediwe ngokubandayoIpayipi lensimbi elingenamthungo libhekisela ekucutshungulweni kokugcina kwepayipi lensimbi ngokudonsa okubandayo, ukugoqa okubandayo, nezinye izinqubo ekushiseni kwegumbi. Ipayipi lensimbi eliqediwe ngokubandayo linokunemba okuphezulu, kanye nekhwalithi enhle ebusweni, futhi ngenxa yokuthi ukucubungula okubandayo kungathuthukisa amandla nokuqina kwepayipi lensimbi, izakhiwo zemishini zepayipi lensimbi eliqediwe ngokubandayo zivame ukuba ngcono kunezo zepayipi lensimbi eliqediwe ngokushisayo. Kodwa-ke, inani elithile lokucindezeleka okusele lingadalwa ngaphakathi kwepayipi lensimbi ngesikhathi sokusebenza okubandayo, okudingeka kuqedwe ngokwelashwa kokushisa okulandelayo.
Ipayipi lensimbi eliqediwe ngokushisa alidingi ukwelashwa ngokushisa.
Amapayipi aqediwe ngokubandayo kufanele afakwe i-anneal engabalulekile, afakwe i-anneal ngokugcwele, noma aphathwe ngokushisa okuvamile ngemva kwenqubo yokugcina yokuqeda ukubanda.

Ukuhlolwa Kokuthamba
Ukudabuka noma ukuphuka kwenzeka ezindaweni ezingu-12 noma 6 ezikhungweni ze-Grade C ezinobukhulu obungu-2.375 in. [60.3 mm] ububanzi bangaphandle kanye nobuncane akufanele kubhekwe njengesisekelo sokwenqatshwa.
Izidingo ezithile zingabonakala ku-I-ASTM A450, into 19.
Ukuhlolwa Kokuvutha
Izidingo ezithile zingabonakala ku-ASTM A450, into 21.
Ubulukhuni
Ibanga C: 89 HRBW (Rockwell) noma 179 HBW (Brinell).
Ipayipi ngalinye lensimbi kufanele lihlolwe ingcindezi ye-hydrostatic noma ukuhlolwa kukagesi okungabhubhisi.
Izidingo zokuhlolwa okuhlobene nokucindezela kwe-hydrostatic ziyahambisana ne-ASTM 450, into 24.
Izidingo zokuhlola ezihlobene nogesi ezingabhubhisi zihambisana ne-ASTM 450, into 26.
Imisebenzi yokwakha iyadingeka kumapayipi ebhoyila ukuqinisekisa ukuthi amapayipi ahlangabezana nezidingo ezithile zesistimu yebhoyila.
Uma efakwa kubhoyila, amashubhu kufanele ame anwebeke futhi abe nobuhlalu ngaphandle kokubonisa imifantu noma amaphutha. Uma esetshenziswa kahle, amashubhu e-superheater kufanele ame yonke imisebenzi yokwakha, ukushisela, kanye nokugoba okudingekayo ukuze kusetshenziswe ngaphandle kokukhula kwamaphutha.
I-Botop Steel ingumkhiqizi kanye nomhlinzeki wamapayipi ensimbi yekhabhoni ashiselwe ngekhwalithi ephezulu evela eShayina, futhi ingumthengisi wamapayipi ensimbi angenamthungo, ikunikeza ipayipi lensimbi elisezingeni eliphezulu, elijwayelekile, nelibiza ngokuncintisana.
