Pipe ea tšepe e sa hloekang ea ASTM
ASTM Stainless Steel Pipe e bua ka liphaephe tsa tšepe tse sa hloekang tse lumellanang le litekanyetso tse behiloeng ke American Society for Testing and Materials (ASTM). Liphaephe tsena li etsoa ka lisebelisoa tsa tšepe tsa boleng bo holimo 'me li etsoa liteko tse matla ho netefatsa boleng le ts'ebetso ea tsona. Litekanyetso tsa ASTM tsa lipeipi tsa tšepe tse sa hloekang li akaretsa likarolo tse fapaneng tse kang boholo, sebopeho sa thepa, thepa ea mochini le mekhoa ea tlhahlobo. Ba fana ka litataiso bakeng sa liphaephe tse se nang moeli le tse cheselitsoeng tse sebelisoang liindastering tse fapaneng, ho kenyeletsoa petrochemical, lik'hemik'hale, oli le khase, meriana, phepelo ea lijo, phepelo ea motlakase le kaho.

E, re moetsi oa tšepe ka lilemo tse 16. Feme ea rona e Anyang. Re fana ka lits'ebeletso tsa tlhahiso, ts'ebetso le ho e etsa bakeng sa lisebelisoa tse fapaneng tsa tšepe.
2. U netefatsa boleng ba hau joang?
Pele ho ts'ebelisano, re ka u fa lisampole tsa mahala, litifikeiti tsa tlhahlobo ea boleng, litifikeiti tse fapaneng tsa maemo a naha, hape re u isa fekthering ea rona ho ea itlhahloba. Seke oa tšoenyeha, ikopanye le rona feela.
3. Phapano ke efe pakeng tsa hao le ba bang?
Joalo ka ha u bona, re baetsi, re ts'episa ho u fa theko e tlase le boleng bo netefalitsoeng.
Re na le mochini oa rona oa ASTM oa tšepe o sa hloekang oa ho sebetsa lipeipi ho sebetsana le boholo bofe kapa bofe joalo ka litlhoko tsa bareki.
Re na le lithane tse 60000 tsa litlhaloso tse tloaelehileng ka setokong bakeng sa ho fana ka matsatsi a 7. Bakeng sa taelo ea bareki, nako ea tlhahiso ke matsatsi a 15-30 a mosebetsi ka mor'a ho fumana depositi.

'Me sebaka sa rona sa polokelo le likepe tsa lipalangoang li ka tšepisa thepa e romelloang boema-kepe ka nako.
4. Nka fumana theko ea sehlahisoa se hlokahalang joang?
Ke tsela e molemo ka ho fetisisa haeba u ka re romella thepa, boholo le bokaholimo, kahoo re ka u hlahisetsa 'me u hlahlobe boleng.Haeba u ntse u
na le pherekano efe kapa efe, ikopanye le rona feela, re ka thabela ho thusa.
5. Na ho lokile ho hatisa logo ea ka lihlahisoa?
Ehlile, re ka fana ka litšebeletso tsa OEM le ODM. U hloka feela ho lokisa logo ea hau mme u re bolelle, re tla e fumana.
