Ukudubula okuqhumayo: fafaza insimbi yokugqwala ethimba i-Sa5, ukugqwala, ukubukeka kwensimbi okuveziwe kakhulu okucwebezelayo okuyisiliva-mhlophe kwensimbi, ubulukhuni obungaphezulu obungu-40 ~ 70μm.
I-spray enamathelayo: qinisa i-epoxy yetiyela yezinga elikhethekile, noma i-primer, isihlathi sesi-5, isikhungo sinamathisele izendlalelo ezine zendwangu yengilazi ye-epoxy, ukujiya okungu-0.9 ~~ 1mm, kuhlanganiswe ngopende opendwe kupende ngamunye isikhawu esomisa isihloko esinamathelayo.
Ukuhlolwa kwekhwalithi: kusukela ekuhloleni okubonakalayo, penda ukubukeka kweyunifomu, bushelelezi, akukho ukugoqa, akukho amabhamuza, akukho mibimbi.Igeji yobukhulu bohlelo lokusebenza, isampula ngamaphesenti angu-5, ikalwa ngokugcwele ukuze kuzuzwe ukujiya komklamo, noma ukujiyisa umdwebo.Ibanjwe ku-5000V 5000V spark pinhole detector ukuvuza, iphinifa kanye nokuhlola ukwahlukanisa ukuze kungabi nenhlansi.Ukunamathela ukuhlola enamathela ukusika umlomo ongunxantathu, aphethwe ukudabuka force kufanele kube nzima ukudonsa up;uma idonswa phezulu, kodwa ungqimba lokuqala lwe-primer kufanele lufakwe ekubukeni kwensimbi yepayipi, ukuze ifaneleke.

Ukugqwala kwangaphandle kwecarbon steel pipengaphandle kwe-tube
Ukusebenzisa i-STIC heavy-duty coatings.
Ukuqhuma kwesibhamu: ukugqwala kwamapayipi ezingane.
Fafaza okokuvikela ukugqwala: Uma ukugqwala kufaneleka, sebenzisa isibhamu sokufutha esingenamoya esiphezulu ukuze ufafaze ungqimba lokuqala lwe-primer ebomvu kuze kube yilapho upende womisa isandla esingenanduku, bese ufafaza ekugcineni kogqinsi lwefilimu yesibili engu-300μm.
Ukuhlola upende: ukuhlolwa okubonakalayo, konke ukujiya kwengane kukalwa kusetshenziswa isilinganiso esibanjwayo sokujiya kazibuthe, ugqinsi lwefilimu oluphelele olungaphezu kuka-600μm.

Amapayipi okugcoba angaphakathi
Amapayipi agqitshiwe kanye nama-penstocks ngaphakathi kwe-anti-corrosion, asetshenziselwa ukulenga ucingo oluhlabayo oluhlabayo, ukufafaza amandla okucindezela angekho ngaphansi kuka-30N/mm2 ulwelwesi lukasimende lodaka.Isilinganiso sengxube kasimende, amanzi: usimende: isihlabathi = 22:200:270;ukusetshenziswa kwamanzi asekhaya;# 525 Portland usimende;isihlabathi semvelo esiqinile, esihlanzekile, esibekwe kahle, okuqukethwe kobumba kungaphansi kuka-2% wosayizi wezinhlayiyana ezingaphansi kuka-2mm.
