ASTM A252spiral welded steel pipee entsoe ka tšepe ea boleng bo holimo e lumellanang le litekanyetso tsa ASTM A252.Tekanyetso e tiisa matla a phahameng le ho tšoarella ha liphaephe, ho etsa hore li tšoanelehe bakeng sa mefuta e fapaneng ea lits'ebetso ho kenyelletsa phetisetso ea oli le khase, metheo ea liqubu le lisebelisoa tsa metsi.Li-welds tsa Spiral li eketsa matla le ho hanyetsa ha liphaephe ho matla a ka ntle, ho etsa bonnete ba hore li ka mamella maemo a phahameng a khatello le maemo a leholimo a thata.
Ho sebetsa hantle le ho baballa litšenyehelo:
O mong oa melemo ea mantlha ea phala ea tšepe ea ASTM A252 spiral welded ke ts'ebetso ea eona e phahameng ea ho kenya le ts'ebeliso.Sebopeho sa eona sa spiral se bonolo ho se tsamaisa le ho se tšoara ka lebaka la boima ba eona bo bobebe ha bo bapisoa le lisebelisoa tse ling tsa liphaephe.Ho feta moo, ho tenyetseha ha liphaephe tsena ho thusa ho kobeha, ho fokotsa litlhoko tsa li-fittings le manonyeletso.Sena ha se boloke nako feela, se boetse se fokotsa haholo litšenyehelo tsa ho kenya, ho etsa hore mofuta ona oa ductwork e be tharollo e theko e boima bakeng sa merero e fapaneng.
E matlafalitsoe ho hanyetsa kutu:
Corrosion ke bothata bo boholo litsamaisong tsa lipeipi, haholo liindastering tse sebetsanang le lik'hemik'hale le lintho tse senyang.Tekanyetso ea ASTM A252 e netefatsa hore liphaephe tsa tšepe tse cheselitsoeng ka spiral li bonts'a khanyetso e ntle ea kutu.Liphaephe tsena li na le liphahlo tse sireletsang tse kang epoxy kapa zinki tse sebetsang e le tšitiso ho lisebelisoa tse senyang, ho lelefatsa bophelo ba bona ba tšebeletso le ho fokotsa litšenyehelo tsa tlhokomelo.Tšobotsi ena e molemo ka ho khetheha lits'ebetsong tse ka tlas'a lefatše kapa tse lebōpong la leoatle moo liphaephe li pepesehelang maemo a thata a tikoloho.
