Liphaephe tsa ho tlatsa
Selelekela sa Lihlahisoa
Litekanyetso tsa thepa:
Liphaephe tsa ho tlatsa li atisa ho aroloa ho latela thepa eo li entsoeng ka eona, e ka kenyelletsang carbon steel, alloy steel kapa lisebelisoa tse ling. Litekanyetso tse khethehileng tsa thepa li tla itšetleha ka ts'ebeliso e reriloeng le tikoloho eo ho tla sebelisoa phala ea ho bokella.
Maemo a Tlhahiso:
Mokhoa oa ho etsa lipeipi tsa ho bokella lipeipi li ka hloka ho lumellana le litekanyetso tse khethehileng ho netefatsa boleng, botšepehi le ts'ebetso ea pipe. Litekanyetso tsena li ka ntlafatsoa ke mekhatlo e kang American Society for Testing and Materials (ASTM), American Petroleum Institute (API), kapa mekhatlo e meng e amehang ea naha kapa ea machaba ea litekanyetso.
Maemo a Moralo:
Ho ka 'na ha hlokoa lipeipi tsa ho tlatsana ho finyella litekanyetso tse itseng tsa moralo ho netefatsa botšepehi ba tsona ba sebopeho le matla a ho jara mojaro. Litekanyetso tsena li ka ntlafatsoa ke mekhatlo ea boenjiniere le ea kaho kapa mekhatlo ea taolo ea mmuso.
Litekanyetso tsa tlhahiso:
Ts'ebetso ea tlhahiso ea Submerged-Arc Welded Steel Pipes e ka latela litekanyetso tse ikhethileng tse behiloeng ke mekhatlo e joalo ka American Petroleum Institute (API), American Society for Testing and Materials (ASTM), kapa mekhatlo e meng ea maemo a naha kapa ea machabeng ka tsela e latelang: API. 5L, API 5CT, ASTM 53, EN10217, DIN 2458, IS 3589, GB/T3091, GB/T9711,EN10217, EN10219
Lintlha tsa kopo:
Liphaephe tsa ho tlatsa li ka aroloa ho latela ts'ebeliso ea tsona e reriloeng, joalo ka ho bokella ka metsing, ho bokella motheo, kapa mefuta e itseng ea mobu kapa maemo a jeoloji. Ho bohlokoa ho shebana le litekanyetso le likarolo tse ikhethileng tse amanang le mofuta oa peipi ea ho bokella e hlokahalang bakeng sa morero o itseng. Haeba u na le litekanyetso tse ikhethileng kapa lihlopha, ka kopo ikutloe u lokolohile ho fana ka lintlha tse ling hore ke tle ke fane ka lintlha tse lebisitsoeng ho tsona.

Mekhoa ea Kopo: Lipeipi tse cheselitsoeng ka longitudinal le tsona li ka hlophisoa ho ipapisitsoe le ts'ebeliso e reriloeng, joalo ka liphaephe tsa oli le khase, lits'ebetso tsa meralo, kapa ts'ebeliso e akaretsang ea indasteri. Etsa bonnete ba hore u bua ka litekanyetso le likarolo tse ikhethileng tse amanang le litlhoko tsa hau, kaha li ka fapana ho latela indasteri le sebaka.
