Ukuqonda nokuvimbela ukugqwala kwezinto ezinhlangothini eWelds yensimbi engenasici

Incazelo ye-Meta: Funda mayelana nokugqwala kwezinto ezinhlamnyezwe ngama-welds wensimbi engagqwali, izimbangela zayo, izindlela zokuvimbela, nokubaluleka kokwelashwa kwesisombululo esikhanyayo. Lungiselela ikhwalithi ye-weld kanye nokuphila isikhathi eside.

Isingeniso:

I-Welding iyinqubo ebalulekile yokujoyina izingxenye zensimbi engagqwali, ikakhulukazi ekukhiqizweni kwamapayipi we-welded. Kodwa-ke, amaphutha we-weld, ikakhulukazi endaweni ye-weld, angathinta kakhulu ubuqotho kanye nokwenza umsebenzi wokugcina. Indaba eyodwa ebucayi ukugqwala okuphakathi, uhlobo lokugqwala okwenziwe kwasendaweni okungaholela ekwehlulekeni okuyinhlekelele.

Kuyini ukugqwala kwenhlangano?

Ukugqwala kwezinhlangano zenhlangothi zenzeka ngensimbi engazinzile engenasici nge-carbon okuqukethwe okudlula u-0.03%. Lapho kufudunyezwa phakathi kuka-425-815 Lokhu kuncipha kwe-chromium ezifundeni zomngcele okusanhlamvu kwenza insimbi ithambekele ekugculiseni ezindaweni ezinolaka. Ngaphansi kwengcindezi, insimbi ingaphuka kule mingcele yokusanhlamvu ebuthaka, okuholela ekulahlekelweni okukhulu kwamandla nokuphikiswa kokugqwala.

Izici ezinikela ngokugqwala kokuhlangana

• Okuqukethwe okuphezulu kwekhabhoni: Amazinga aphakanyisiwe calbon ku-wensimbi akhuthaza ukwakheka kwe-chromium carbides.

• Ukuvezwa kokushisa: Ukuchayeka isikhathi eside kububanzi bokushisa bokuzwakala (425-815 ℃) ngesikhathi sokushiswa noma ukwelashwa okushisa.

• Izindawo ezilimazayo: Ukuchayeka kwabezindaba ezinolaka, njengama-acid noma ama-chlorides, kusheshisa inqubo yokugqwala.

Izindlela Zokuvimbela:

1. Ukulawulwa Kwokwakheka Kwamakhemikhali:

• Ukungeza izinto zokuzinza njenge-titanium noma i-niobium ukubopha ngekhabhoni, ukuvimbela ukwakheka kwe-chromium carbide.

• Kusetshenziswa insimbi ephansi yekhabhoni (isib. 304l, 316l) ngokuqukethwe kwekhabhoni ngaphansi kwe-0.03%.

• Ukulungisa ukwakheka kwamakhemikhali kwe-weld ukwandisa ingxenyana enkulu ye-Chrome.

2. Ukusebenza kwenqubo ye-Welding:

• Ukunciphisa ukufakwa kokushisa nokulawula indawo ethintekile ekushiseni (hathini).

• Ukusebenzisa amasu asheshayo we-welding kanye nokupholisa ukunciphisa isikhathi esichithwa ebangeni lokushisa elizwakalayo.

3. Ukwelashwa Kwesisombululo Esikhanyayo:

• Le nqubo yokwelashwa ekushiseni ifaka ukufudumeza ngokushesha insimbi ekushiseni okuphezulu bese uyipholisa ngokushesha ukuncibilikisa i-chromium carbides futhi ibuyise ukumelana nokugqwala.

• Isibonelo, imishini ye-inthanethi yeHengao yezobuchwepheshe esheshayo ishisa futhi iphole amapayipi ensimbi engagqwali ngaphansi kokuvikelwa kwegesi, kusetshenziswa ukufudumeza kokufudumeza kanye nokubuyiselwa kwe-graphite okupholile kwe-hydrogen ngokudluliswa okusebenzayo.

Ukubaluleka kokwelashwa kwesixazululo esikhanyayo:

Ukwelashwa kwesixazululo esikhanyayo kubalulekile ukuze kukhiqizwe amapayipi anekhwalithi ephezulu yezimboni. Isusa ngempumelelo ingozi yokugqwala okuqhubekayo ngokuqinisekisa ukusatshalaliswa okunama-chromium ngensimbi kwinsimbi yensimbi. Le nqubo ibaluleke kakhulu kuzinhlelo zokusebenza lapho insimbi engenacala ivezwa khona ezindaweni ezihlanzekile noma ezicindezelwe kakhulu.

Isiphetho:

Ukuqonda nokuvimbela ukugqwala okunamandla kubalulekile ekuqinisekiseni isikhathi eside kanye nokwethenjwa kwama-welds wensimbi engagqwali. Ngokulawula ukwakheka kwamakhemikhali, ukwenza kahle izinqubo ze-welding, futhi kusetshenziswe ukwelashwa kwesisombululo esikhanyayo, abakhiqizi banganciphisa kakhulu ubungozi befomu elilimazayo lokugqwala.

Amagama agqamile: Ukugqwala kwe-Songsranur, ama-welds wensimbi engagqwali, amaphutha we-weld, ukwelashwa okukhanyayo, inqubo ye-welding, i-auntenitic yensimbi, insimbi engenacala, amapayipi angenacala.
