Hlahisa:
Ha ho tluoa tabeng ea nts'etsopele ea meralo ea motheo, litsamaiso tsa lipeipi ke karolo ea bohlokoa e bapalang karolo ea bohlokoa liindastering tse fapaneng. Ho sebelisa thepa le mekhoa e nepahetseng kahong ea lipeipi ho netefatsa ho tšoarella, matla le ts'epo, lePipe ea tšepe e bōpehileng joaloka spiral ASTM A252e ka pele ho tsoelo-pele ena ea theknoloji. Ho blog ena, re tla shebisisa ka hloko litšobotsi le melemo e ikhethang ea liphaephe tsena tse ikhethang tse fetohileng karolo ea bohlokoa mererong ea kaho ea sejoale-joale.

Matla le ho Tšoarella ho sa Bapisoeng le ho Fela:
ASTM A252phala ea tšepe e svetselitsoeng ka spirale entsoe ka tšepe ea boleng bo holimo e fihlelang maemo a ASTM A252. Maemo ana a tiisa matla a phahameng le ho tšoarella ha liphaephe, e leng se etsang hore li lokele mefuta e fapaneng ea lits'ebetso ho kenyeletsoa phetiso ea oli le khase, metheo ea likhoele le meralo ea motheo ea metsi. Li-weld tse potolohang li eketsa matla le khanyetso ea liphaephe khahlanong le matla a kantle, ho netefatsa hore li khona ho mamella maemo a khatello e phahameng le maemo a leholimo a thata.
Bokgoni bo botle le katleho e ntle:
E 'ngoe ea melemo ea mantlha ea ASTM A252 spiral welded phala ea tšepe ke bokhoni ba eona bo phahameng ba ho kenya le ho sebelisa. Moralo oa eona oa spiral o bonolo ho o tsamaisa le ho o sebetsana ka lebaka la boima ba oona bo bobebe ha o bapisoa le thepa e meng ea phala. Ho feta moo, ho tenyetseha ha liphaephe tsena ho nolofalletsa ho kobeha, ho fokotsa litlhoko tsa li-fitting le li-joints. Sena ha se boloke nako feela, hape se fokotsa litšenyehelo tsa ho kenya haholo, e leng se etsang hore mofuta ona oa li-ductwork e be tharollo e theko e tlaase bakeng sa merero e fapaneng.
Ho hanyetsa ts'enyeho e matlafalitsoeng:
Ho senyeha ha metsi ke bothata bo boholo lits'ebetsong tsa liphaephe, haholo-holo liindastering tse sebetsanang le lik'hemik'hale le lintho tse senyang. Tekanyetso ea ASTM A252 e netefatsa hore liphaephe tsa tšepe tse phuthetsoeng ka spiral li bontša ho hanyetsa ho senyeha ho hoholo. Liphaephe tsena li na le liphaephe tse sireletsang tse kang epoxy kapa zinc tse sebetsang e le tšitiso ho lintho tse senyang, tse eketsang bophelo ba tsona ba ts'ebeletso le ho fokotsa litšenyehelo tsa tlhokomelo. Tšobotsi ena e molemo haholo lits'ebetsong tsa ka tlas'a lefatše kapa tsa lebopong moo liphaephe li pepesehetseng maemo a thata a tikoloho.
Bokhoni bo boholo ba ho jara:
Tšobotsi e 'ngoe ea bohlokoa ea ASTM A252 spiral welded phala ke bokhoni ba eona bo botle ba ho jara mojaro. Theknoloji ea spiral welding e sebelisoang ts'ebetsong ea tlhahiso e ntlafatsa matla le bokhoni ba phaephe ba ho mamella meroalo e boima. Ebang e sebelisoa kahong ea borokho, metheo ea meaho kapa liphaephe tse ka tlas'a lefatše, liphaephe tsena li fana ka botšepehi bo phahameng ba meaho, li fokotsa kotsi ea ho hloleha le ho netefatsa polokeho ea nako e telele ea merero e fapaneng ea meralo ea motheo.
Tšireletso ea tikoloho:
Nakong ena eo tshireletso ya tikoloho e leng taba ya lefatshe ka bophara, ho kgetha thepa e nepahetseng ya kaho ho bohlokwa. Phaephe ya tshepe e welilweng ka spiral ASTM A252 e latela mekgwa ya kaho e tsitsitseng ka lebaka la ho tshwarella ha yona le ho kgona ho sebediswa hape. Diphaephe di na le nako e telele ya tshebeletso mme di ka sebediswa hape habonolo qetellong ya bophelo ba tsona, e leng se fokotsang tlhoko ya ho ntshwa ha thepa e ntjha ha ka nako e ts'oanang ho fokotsa ditshila le mosi o tswang khaboneng.
Ha re phethela:
Phaephe ea tšepe e bōpehileng joaloka spiral ASTM A252 e fetotse indasteri ea liphaephe ka matla a eona a phahameng, ho tšoarella le ho boloka litšenyehelo ka katleho. Liphaephe tsena li fihlela kapa li feta maemo a indasteri, e leng se etsang hore e be khetho ea pele liindastering tse ngata.
