Ho Hanela Tshenyo (Teko ea HIC le SSC)
PIPE ea A106 Gr B NACE e etselitsoe ho mamella maemo a ts'ebeletso e bolila, 'me e lekoa ka thata bakeng sa Hydrogen Induced Cracking (HIC) le Sulfide Stress Cracking (SSC) ho latela maemo a MR 0175. Liteko tsena li bohlokoa bakeng sa ho lekola bokhoni ba phaephe ba ho sebetsa libakeng tseo ho tsona ho nang le hydrogen sulfide kapa metsoako e meng ea asiti.
Teko ea HIC (Hydrogen Induced Peaking)
Teko ena e lekola ho hanyetsa ha phaephe mapetsong a bakoang ke haeterojene a hlahang ha a pepesehetse tikoloho e bolila, joalo ka a nang le hydrogen sulfide (H₂S).
Teko ea SSC (Sulfide Stress Cracking)
Teko ena e hlahloba bokgoni ba phaephe ba ho hanela ho petsoha tlasa kgatello ha e pepeseditswe ke hydrogen sulfide. E etsisa maemo a fumanwang dibakeng tse bolila tsa tshebeletso jwalo ka masimo a oli le kgase.
Liteko tsena ka bobeli li netefatsa hore PIPE ea A106 Gr B NACE e fihlela litlhoko tse thata tsa liindasteri tse sebetsang libakeng tse bolila, 'me tšepe e hanela ho petsoha le mefuta e meng ea mafome.
Matlotlo a 'Mele
PIPE ea A106 Gr B NACE e na le litšobotsi tse latelang tsa 'mele tse netefatsang hore e sebetsa ka mokhoa o tšepahalang tlas'a mocheso o feteletseng le khatello:

●Thepa e Romelloang Kantle ho Naha:Ka boiphihlelo ba ho romela kantle ho naha linaheng tse fetang 100, Womic Steel e netefatsa hore liphaephe tsa boleng bo holimo li tla ka mokhoa o tšepahalang le o nakong lefatšeng ka bophara.
Qetello
PIPE ea A106 Gr B NACE e tsoang ho Womic Steel e kopanya thepa e ikhethang ea mechini, ho hanyetsa mafome, le ho tšepahala maemong a tšebeletso e bolila. E loketse lits'ebetso tsa mocheso o phahameng, khatello e phahameng liindastering tse kang oli le khase, petrochemical le ts'ebetso ea lik'hemik'hale. Litekanyetso tse thata tsa liteko, ho kenyeletsoa le liteko tsa HIC le SSC ho latela MR 0175, li netefatsa ho tšoarella ha phaephe le ho hanyetsa mafome libakeng tse thata.
Bokgoni bo tswetseng pele ba tlhahiso ya Womic Steel, boitlamo ba boleng, le boiphihlelo bo boholo ba ho romela thepa kantle ho naha lefatsheng ka bophara di etsa hore e be molekane ya tshepahalang wa NACE PIPES e sebediswang ditshebedisong tsa bohlokwa.
Khetha Womic Steel Group e le molekane oa hau ea tšepahalang bakeng sa Liphaephe le Lisebelisoa tsa Tšepe e sa Khaotseng tsa boleng bo holimo le ts'ebetso e sa hlōloeng ea ho fana ka thepa. Rea u amohela!
