Ho utloisisa ASTM A139: Mokokotlo oa Pipe ea SAWH le Likopo tsa Pipe tse Welded Spiral

Lefats'eng la liphaephe tsa indasteri, likhoutu le litekanyetso tse laolang lisebelisoa tse sebelisoang li bohlokoa ho netefatsa polokeho, ho tšoarella le ts'ebetso. E 'ngoe ea litekanyetso tsena keASTM A139, e nang le karolo ea bohlokoa tlhahisong le ts'ebetsong ea liphaephe tsa SAWH (spiral arc welded hollow) le liphaephe tse cheselitsoeng ka spiral. Ho blog ena, re tla tšohla bohlokoa ba ASTM A139, litšobotsi tsa phala ea SAWH, le melemo ea Helical Welded Pipe liindastering tse fapaneng.

ASTM A139 ke eng?

ASTM A139 ke tlhaloso e ntlafalitsoeng ke Mokhatlo oa Amerika oa Teko le Lisebelisoa (ASTM) o hlalosang litlhoko tsa phala ea tšepe e entsoeng ka electrofusion (arc). Tekanyetso ena e sebetsa haholo-holo liphaepheng tse sebelisoang ho tsamaisa maro le likhase. Tlhaloso e akaretsa lihlopha tse ngata tsa tšepe 'me e etsa bonnete ba hore liphaephe tse hlahisoang li kopana le thepa e khethehileng ea mochine le metsoako ea lik'hemik'hale.

Ka ho khomarela litekanyetso tsena, bahlahisi ba ka etsa bonnete ba hore lihlahisoa tsa bona li ka tšeptjoa ebile li loketse mefuta e sa tšoaneng ea lisebelisoa, ho tloha ho lipalangoang tsa oli le khase ho ea ho haha ​​​​lisebelisoa tsa mohaho.

Karolo ea lipeipi tsa SAWH

Pipe ea SAWH kapa spiral arc welded hollow pipe ke mofuta oa peipi e cheselitsoeng e entsoeng ka spirally welding masela a tšepe a bataletseng hore e be sebopeho sa cylindrical. Mokhoa ona oa tlhahiso o lumella ho thehoa ha liphaephe tse nang le bophara bo boholo tse matla le tse bobebe. Theknoloji ea spiral welding e sebelisoang hoSAWH lipeipi e fana ka melemo e mengata, ho kenyelletsa:

1. Katleho ea Litšenyehelo:Ts'ebetso ea tlhahiso ea liphaephe tsa SAWH hangata e na le moruo ho feta mekhoa e tloaelehileng, e etsang hore e be khetho e khahlehang bakeng sa merero e meholo.

2. VERSATILITY:Pipe ea SAWH e ka etsoa ka boholo le botenya bo sa tšoaneng, e etsa hore e tšoanelehe bakeng sa mefuta e mengata ea lisebelisoa, ho akarelletsa le phepelo ea metsi, tsamaiso ea metsi a litšila le likarolo tsa mohaho.

3. Matla a Matlafalitsoeng:Mohaho o entsoeng ka li-spiral o fana ka matla a eketsehileng le ho hanyetsa khatello ea ka ntle, ho etsa hore pipe ea SAWH e be e loketseng bakeng sa maemo a phahameng a khatello ea kelello.

Melemo ea spiral welded pipe

Spiral welded pipe ke mofuta o mong oa phala e cheselitsoeng e hlahisoang ka theknoloji ea spiral welding. Mokhoa ona o kenyelletsa ho phuthela lesela la tšepe ho pota-pota mandrel le ho e tjheseletsa ka bilika e sa khaotseng.Helical Welded Pipe e fana ka melemo e mengata, ho kenyelletsa:

1. Litšobotsi tse ntlafetseng tsa phallo:Sebaka se ka hare se boreleli sa Helical Welded Pipe se fokotsa moferefere le ho ntlafatsa phallo ea mokelikeli, e leng se etsang hore e be se loketseng bakeng sa lisebelisoa tsa indasteri ea oli le khase.

2. HO Fokotse boima ba 'mele:Sebopeho sa spiral se lumella marako a masesaane ntle le ho senya matla, ho etsa hore pipe e be bobebe le ho e tšoara habonolo le ho e tsamaisa.

3. Bolelele boo u ka bo khethang:Helical Welded Pipe e ka hlahisoa ka bolelele bo bolelele, e fokotsa palo ea manonyeletso e hlokahalang phala le ho fokotsa monyetla oa ho lutla.

Ha re phethela

Ka kakaretso, ASTM A139 ke tekanyetso ea bohlokoa bakeng sa tlhahiso ea phala ea SAWH le pipe e entsoeng ka spiral welded, ho netefatsa hore likarolo tsena tsa bohlokoa li finyella litekanyetso tse hlokahalang tsa polokeho le ts'ebetso. Thepa e ikhethang ea SAWH le spiral welded pipe li etsa hore e be tsa bohlokoa haholo liindastering ho tloha kahong ho ea ho matla. Ha thekenoloji e ntse e hatela pele, bohlokoa ba ho khomarela litekanyetso tse theiloeng joalo ka ASTM A139 bo tla hola feela ho netefatsa hore meralo ea motheo eo re itšetlehileng ka eona e lula e bolokehile ebile e sebetsa hantle. Hore na o moenjiniere, mokonteraka, kapa molaoli oa projeke, ho utloisisa litekanyetso tsena le melemo ea mefuta ena ea liphaephe ho bohlokoa ho etsa liqeto tse nepahetseng mabapi le merero ea hau.
