Ho utloisisa ASTM A139: Mokokotlo oa Litšebeliso tsa Pipe ea SAWH le Pipe e Welded Spiral

Lefatšeng la liphaephe tsa indasteri, melao le maemo a laolang thepa e sebelisoang li bohlokoa haholo ho netefatsa polokeho, ho tšoarella le ts'ebetso. E 'ngoe ea maemo ana keASTM A139, e bapalang karolo ea bohlokoa tlhahisong le ts'ebelisong ea liphaephe tsa SAWH (spiral arc welded hollow) le liphaephe tse spiral welded. Ho blog ena, re tla buisana ka bohlokoa ba ASTM A139, litšobotsi tsa phaephe ea SAWH, le melemo ea Phaephe e Welded ea Helical liindastering tse fapaneng.

ASTM A139 ke eng?

ASTM A139 ke tlhaloso e ntshetsweng pele ke Mokhatlo wa Amerika wa Teko le Disebediswa (ASTM) e hlalosang ditlhoko tsa phaephe ya tshepe e welditsweng ka motlakase (arc). Tekanyetso ena e sebetsa haholoholo ho diphaephe tse sebediswang ho tsamaisa metsi le dikgase. Tlhaloso ena e akaretsa mefuta e mengata ya dikereiti tsa tshepe mme e netefatsa hore diphaephe tse hlahiswang di fihlela thepa e ikgethang ya mechini le dikhemikhale.

Tekanyetso ea ASTM A139 e bohlokoa ho bahlahisi le baenjiniere hobane e fana ka tataiso mabapi le ts'ebetso ea tlhahiso, ho kenyeletsoa mekhoa ea ho tjheseletsa le mehato ea taolo ea boleng e lokelang ho nkuoa. Ka ho latela maemo ana, bahlahisi ba ka netefatsa hore lihlahisoa tsa bona lia tšepahala ebile li loketse lits'ebetso tse fapaneng, ho tloha ho lipalangoang tsa oli le khase ho isa lits'ebetsong tsa meaho ea meaho.

Karolo ea phaephe ea SAWH

Phaephe ea SAWH kapa phaephe e se nang letho e phuthetsoeng ka arc e spiral ke mofuta oa phaephe e phuthetsoeng e entsoeng ka ho tjheseletsa ka mokhoa o spirally lithapo tsa tšepe tse bataletseng hore e be sebopeho sa cylindrical. Mokhoa ona oa tlhahiso o lumella ho thehoa ha liphaephe tse bophara bo boholo tse matla le tse bobebe. Theknoloji ea ho tjheseletsa ka mokhoa o spiral e sebelisitsoeng hoLiphaephe tsa SAWH e fana ka melemo e 'maloa, ho kenyeletsoa:

1. Katleho ea Litšenyehelo:Ts'ebetso ea tlhahiso ea liphaephe tsa SAWH hangata e theko e tlase ho feta mekhoa ea setso, e leng se etsang hore e be khetho e khahlang bakeng sa merero e meholo.

2. HO FETISISA HA LINTHO:Phaephe ea SAWH e ka etsoa ka boholo le botenya bo fapaneng, e leng se etsang hore e lokele mefuta e mengata ea lits'ebetso, ho kenyeletsoa phepelo ea metsi, litsamaiso tsa metsi a litšila le likarolo tsa sebopeho.

3. Matla a Ntlafalitsoeng:Kaho e entsoeng ka ho tjheseletsa ka sekontiri e fana ka matla a eketsehileng le ho hanyetsa khatello ea kantle, e leng se etsang hore phaephe ea SAWH e be ntle bakeng sa libaka tse nang le khatello e phahameng.

Melemo ea phaephe e spirale e welded

Phaephe e tjheseditsweng ka moya ke mofuta o mong wa phaephe e tjheseditsweng e hlahiswang ka ho sebedisa theknoloji ya ho tjheseletsa ka moya. Mokgwa ona o kenyeletsa ho phuthela mothapo wa tshepe ho potoloha mandrel le ho e tjheseletsa ka mothapo o tswelang pele.Pipe e nang le Helical Welded e fana ka melemo e 'maloa, ho kenyeletsoa:

1. Litšobotsi tse ntlafetseng tsa phallo:Bokaholimo bo boreleli ba kahare ba Helical Welded Pipe bo fokotsa moferefere le ho ntlafatsa phallo ea mokelikeli, e leng se etsang hore e be e loketseng lits'ebetso tsa indasteri ea oli le khase.

2. BOIMA BO FOKOTSOE:Moralo oa spiral o lumella mabota a masesaane ntle le ho fokotsa matla, e leng se etsang hore phaephe e be bobebe le ho ba bonolo ho e sebetsana le ho e tsamaisa.

3. Bolelele bo ka Ikgethang:Pipe e Welded ea Helical e ka hlahisoa ka bolelele bo bolelele, e fokotsa palo ea manonyeletso a hlokahalang ka har'a pipe le ho fokotsa monyetla oa ho lutla.

Ha re phethela

Ka bokhutšoanyane, ASTM A139 ke tekanyetso ea bohlokoa bakeng sa tlhahiso ea phaephe ea SAWH le phaephe e kopantsoeng ka spiral, e netefatsang hore likarolo tsena tsa bohlokoa li fihlela maemo a polokeho le ts'ebetso a hlokahalang. Thepa e ikhethang ea SAWH le phaephe e kopantsoeng ka spiral e etsa hore e be ea bohlokoa haholo indastering ho tloha kahong ho ea ho eneji. Ha theknoloji e ntse e tsoela pele ho hatela pele, bohlokoa ba ho khomarela maemo a thehiloeng joalo ka ASTM A139 bo tla hola feela ho netefatsa hore meralo ea motheo eo re itšetlehileng ka eona e lula e sireletsehile ebile e sebetsa hantle. Hore na u moenjiniere, rakonteraka, kapa mookameli oa projeke, ho utloisisa maemo ana le melemo ea mefuta ena ea liphaephe ho bohlokoa ho etsa liqeto tse nang le tsebo mabapi le merero ea hau.
