Ukuthuthukiswa kwezimboni kushintsha ngokushesha, futhi amapayipi ensimbi engagqwali nawo alandela ukuthuthukiswa kwezimboni ukuhlangabezana nezidingo zokuthuthukiswa kwezimboni ezihlukahlukene. Okulandelayo ukusetshenziswa okubanzi kwamapayipi ensimbi engagqwali ezimbonini ezahlukahlukene:
Uhlobo lwepayipi lensimbi engagqwali
1. Ipayipi lensimbi engenamthungo
Ipayipi lensimbi engenamthungo ukusetshenziswa kwenqubo yokunwetshwa okubandayo, egoqekayo noma ebandayo, ngaphandle kwanoma iyiphi ipayipi lensimbi yomthungo. Ngenxa yokuthi izindonga zangaphakathi nangaphandle zepayipi elingenamthungo zibushelelezi futhi zihlanzekile, linokusebenza kwekhwalithi elihle kakhulu futhi lisetshenziswa kabanzi ku-petroleum, amakhemikhali, izindiza, i-metallurgy nakweminye imikhakha yezimboni. Insimbi engagqwali ipayipi izinto nekhono zihlanganisa 304, 304L, 321, 316, 316L, 310S nokunye.
2. Ipayipi elihlanganisiwe lensimbi engagqwali
Insimbi engagqwali ashiselwe ipayipi iyipayipi yensimbi eyenziwe inqubo Welding. Ngenxa yezindleko zayo eziphansi zokukhiqiza, ukukhiqizwa okulula nezinye izinzuzo, ipayipi elihlanganisiwe lensimbi engenasici lisetshenziswa kabanzi, njengokudla, uphethiloli, imithi, amakhemikhali nezinye izimboni. Insimbi engagqwali ashiselwe amapayipi izinto ngokuyinhloko 304, 316L, 321 nokunye.
Kunezindlela ezihlukahlukene zokuxhuma zamapayipi ensimbi engagqwali. Izinhlobo zokufakwa kwamapayipi ezivamile zihlanganisa uhlobo lokucindezelwa, uhlobo lokucindezela, uhlobo lwenyunyana, uhlobo lwe-push, uhlobo lwentambo yokusunduza, uhlobo lwesokhethi yokushisela, uxhumano lwe-flange lwenyunyana, uhlobo lwe-welding kanye nokushisela kanye nokuxhumeka kwendabuko. Izindlela zokuxhumana zochungechunge ezitholakalayo ezihlanganisiwe. Lezi zindlela zokuxhuma zinezinhlelo zokusebenza ezihlukene ngokwezimiso zazo ezihlukene, kodwa eziningi zazo zilula ukuzifaka, ziqinile futhi zithembekile. Indandatho yokuvala uphawu noma impahla ye-gasket esetshenziselwa ukuxhuma ngokuvamile yenziwe ngerabha ye-silicone, irabha ye-nitrile nerabha ye-EPDM ehlangabezana nezindinganiso zikazwelonke, ezikhulula abasebenzisi ekukhathazekeni.
Ipayipi lesikwele lensimbi engagqwaliimodi yokuthutha
1. Ezokuthutha ezihamba phansi
Imodi yokuthutha yomhlaba yepayipi yesikwele yensimbi engagqwali ihlanganisa izindlela ezimbili zokuthutha ujantshi kanye nokuhamba komgwaqo. Izinto zokuthutha ngololiwe zizinzile, kuyilapho ezokuthutha zomgwaqo zivumelana nezimo. Ukuze kuqinisekiswe ukuphepha kwezokuthutha, amapayipi wesikwele ensimbi engagqwali adinga ukupakishwa nge-anti-rust, anti-leakage kanye ne-anti-vibration ukugwema ukuguga ngenxa yokungqubuzana ngesikhathi sokuthutha. Izinto zokupakisha zingasebenzisa ama-pallets okhuni, amabhokisi okhuni, amafreyimu okhuni, njll, kodwa futhi kudingeka ukunaka ukuhlolwa okuvamile, ukugcinwa nokugcinwa ngesikhathi sokuthutha.
2. Indlela yokuthumela
Ezokuthutha ezihamba ibanga elide, ukuthunyelwa kwepayipi lensimbi engagqwali kuvame ukukhetha ukonga futhi okuphephile. Lapho ukhetha ezokuthutha olwandle, kuyadingeka ukukhetha ngokunengqondo uhlobo lomkhumbi olufanele kanye nohlelo lokulayisha ngokwesimo sangempela sempahla ehlukene, izilwandle ezihlukene nezinkathi ezahlukene zonyaka. Enqubweni yokuthunyelwa kwemikhumbi, kuyadingeka ukupakisha nokuthutha ngokuhambisana ngokuqinile nezindinganiso zikazwelonke nezifanele, ezingavimbela izimpahla ukuthi zingathinteki imvelo, isimo sezulu, izinga lokushisa, umswakama kanye nezinye izici ngezinga elithile.
Ezokuthutha:I-Express (Ukulethwa Kwesampula), Umoya, Umzila Wesitimela, Umhlaba, Ukuthunyelwa Kwasolwandle (i-FCL noma i-LCL noma i-Bulk)
