Maemo a ASTM bakeng sa Pipe ea Tšepe ea Khabone
Mokhatlo oa Amerika oa Liteko le Lisebelisoa (ASTM) o thehile litekanyetso tse fapaneng bakeng sa liphaephe tsa tšepe ea carbon, tse hlalosang ka botlalo boholo, sebopeho, sebopeho sa lik'hemik'hale, thepa ea mechini le litlhoko tse ling tsa tekheniki tsa liphaephe tsa tšepe. Tse latelang ke litekanyetso tse 'maloa tse tloaelehileng tsa ASTM bakeng sa liphaephe tsa tšepe ea carbon:
1. Liphaephe tsa Tšepe ea Khabone tse se nang Seamless
ASTM A53: E sebetsa ho tse tjhitilweng le tse se nang sekoli tse ntšo leliphaephe tsa tšepe tse qhibilihisitsoeng ka ho chesa, e sebediswang haholo bakeng sa merero ya meaho, ditsamaiso tsa diphaephe, jj. Tekanyetso ena e arotsoe ka mekgahlelo e meraro: A, B, le C ho ya ka botenya ba lebota.
ASTM A106: Liphaephe tsa tšepe ea khabone tse se nang sekoli tse loketseng tšebeletso ea mocheso o phahameng, tse arotsoeng ka Sehlopha sa A, B, le C, tse sebelisoang haholo-holo liphaepheng tsa phetisetso ea oli, khase ea tlhaho le liindastering tsa lik'hemik'hale.
ASTM A519: E sebetsa ho li-bar tsa tšepe ea khabone e se nang sekoli le liphaephe bakeng sa ho sebetsa, ka litlhoko tse tiileng tsa mamello ea boholo bo itseng.
2. Liphaephe tsa Tšepe ea Khabone e Welded
ASTM A500: E sebetsa ho sekwere se tjheseditsweng se batang le se se nang mohele,khutlonnetsepale liphaephe tse ling tsa tšepe tse nang le sebopeho se bōpehileng joaloka tsa mohaho, tse sebelisoang hangata mehahong ea meaho.
ASTM A501: E sebetsa ho liphaephe tsa tšepe tse phuthetsoeng ka ho chesoa le tse se nang sekoere, tse khutlonnetsepa le tse ling tse nang le sebopeho sa sebopeho sa tšepe.
ASTM A513: E sebetsa ho motlakaseliphaephe tsa tšepe tse chitja tse bōpehileng joaloka welded, e sebediswang haholo bakeng sa ditshebediso tsa ho sebetsa ka mechine le tsa meaho.
3. Liphaephe tsa tšepe ea carbon bakeng sa liboiler le li-superheater
ASTM A179: E sebetsa ho liphaephe tsa boiler tsa tšepe e nang le khabone e tlase tse huloang ka serame, e loketse lits'ebetso tsa mouoane o nang le khatello e phahameng.
ASTM A210: E sebetsa ho liphaephe tsa boiler tsa tšepe ea khabone e se nang moedi, tse arotsoeng ka mekhahlelo e mene: A1, A1P, A2, le A2P, tse sebelisoang haholo bakeng sa liboiler tsa khatello e mahareng le e tlase.
ASTM A335: E sebetsa ho liphaephe tsa tšebeletso tsa mocheso o phahameng tsa tšepe ea ferritic alloy e se nang seamless, tse arotsoeng ka mekhahlelo e mengata, joalo ka P1, P5, jj., e loketse liphaephe tsa mocheso o phahameng indastering ea petrochemical le ea motlakase.
4. Liphaephe tsa tšepe ea khabone bakeng sa liliba tsa oli le khase
ASTM A252: E sebetsa ho arc e potileng e koahetsoeng ke seamliphaephe tsa tšepe tse qhibilihisitsoengbakeng sa liqubu, tse sebelisoang haholo kahong ea sethala sa leoatleng.
ASTM A506: E sebetsa ho liphaephe tsa tšepe tsa sebopeho tse matla haholo tse nang le motsoako o tlase, tse loketseng tlhahiso ea lisebelisoa tsa tšimo ea oli le khase.
ASTM A672: E sebetsa ho liphaephe tsa tšepe tsa silicon tsa carbon manganese tse nang le chai e ngata, tse loketseng lits'ebetso tse hlokang matla a holimo.
Tlhahlobo ea API 5L: Le hoja e se tekanyetso ea ASTM, ke tekanyetso e amoheloang machabeng bakeng sa liphaephe tsa tšepe bakeng sa liphaephe tsa oli le khase, e akaretsang mefuta e mengata ea liphaephe tsa tšepe ea khabone.
5. Liphaephe tsa tšepe ea khabone bakeng sa merero e khethehileng
ASTM A312: E sebetsa ho liphaephe tsa tšepe e sa ruseng tse se nang moedi le tse tjheseditsweng. Leha e le haholo-holo bakeng sa tšepe e sa ruseng, e boetse e kenyelletsa litlhaloso tse ling tsa tšepe ea khabone.
ASTM A795: E sebetsa ho li-billet tsa tšepe ea khabone le tsa alloy, li-billet tse chitja le lihlahisoa tsa tsona tse entsoeng ka ho lahla le ho betla ho tsoelang pele, tse loketseng masimo a itseng a indasteri.
Mokhoa oa ho khetha maemo a nepahetseng a ASTM
Ho khetha maemo a nepahetseng a ASTM ho latela litlhoko tse itseng tsa kopo:
Tikoloho ea tšebeliso: Nahana ka lintlha tse kang mocheso oa ts'ebetso, maemo a khatello, le boteng ba mecha ea phatlalatso e senyang.
Litšobotsi tsa mechine: Fumana matla a fokolang a tlhahiso a hlokahalang, matla a ho thapolla le matšoao a mang a bohlokoa.
Ho nepahala ha litekanyo: Bakeng sa lits'ebetso tse ling tsa ho sebetsa ka ho nepahala ha ho sebetsa kapa ho kopanya, ho ka hlokahala mamello ea bophara ba kantle le botenya ba lebota e laoloang ka thata.
Kalafo ea bokaholimo: Hore na ho hlokahala galvanizing e chesang, pente kapa mekhoa e meng ea kalafo ea ho thibela mafome.
