Kumenyekanisha ibicuruzwa
Kumenyekanisha prium yacu ASTM A252 ingano yubunini bwagenewe guhuza ibisabwa bikenewe byubwubatsi bugezweho nubwubatsi. Urukuta rwacu rw'icyuma ibirundo birasobanutse neza kandi byakozwe mubuhanga kugirango tumenye ko bishobora gukoreshwa nk'umutwaro wizewe utwara abanyamuryango cyangwa nk'imyenda iramba kubirundo bya beto.
Ibipimo byubunini bwa ASTM A252 byashizweho kugirango bitange imbaraga zidasanzwe kandi zihamye, bituma biba byiza mubikorwa bitandukanye birimo fondasiyo, inyubako zo hanze, hamwe nimishinga iremereye yubwubatsi. Ibirundo byibyuma byerekana imiterere ya silindrike kugirango igabanye neza imitwaro, mugihe uburebure bwurukuta rwizina butuma buramba kandi bikarwanya ibidukikije.
Iyo uhisemo ibyacuIngano ya ASTM A252ibisobanuro, ushora mubicuruzwa bitujuje ubuziranenge bwinganda gusa, ariko birarenze. Twiyemeje ubuziranenge no guhanga udushya tubona ibicuruzwa byizewe, bikora neza, kandi bijyanye nibyo ukeneye.
Ibyiza bya sosiyete
Uruganda rwacu ruherereye mu mujyi wa Cangzhou, mu Ntara ya Hebei, rwabaye urufatiro rw’inganda z’ibyuma kuva rwashingwa mu 1993. Uru ruganda rufite ubuso bwa metero kare 350.000 kandi rufite ibikoresho by’ikoranabuhanga bigezweho ndetse n’imashini, bidushoboza gukora ibicuruzwa by’ibyuma byo mu rwego rwo hejuru byujuje ubuziranenge mpuzamahanga. Hamwe n'umutungo wose wa miliyoni 680 z'amafaranga y'u Rwanda, dufite abakozi 680 b'abahanga bitangiye gutanga indashyikirwa mu bice byose by'ibikorwa byacu.
Inyungu y'ibicuruzwa
Ubwa mbere, imiterere ya silindrike itanga uburyo bwo gukwirakwiza neza imitwaro, bigatuma iba nziza kubikorwa byimbitse. Imiterere yicyuma itanga imbaraga zidasanzwe kandi ziramba, byemeza ko ibyo birundo bishobora kwihanganira imizigo minini n’ibidukikije bikabije. Byongeye kandi, impinduramatwara ya ASTM A252 ituma ikoreshwa muburyo butandukanye, kuva ku biraro kugeza ku nyubako, bikongerera imbaraga abajenjeri naba rwiyemezamirimo.
Ibura ry'ibicuruzwa
Imwe mu ngaruka zigaragara ni amahirwe yo kwangirika, cyane cyane mubidukikije bifite ubuhehere bwinshi cyangwa imiti. Mugihe impuzu zo gukingira zishobora kugabanya iki kibazo, zirashobora kongera ibiciro hamwe nibisabwa byo kubungabunga.
Byongeye kandi, inzira yo gukoraASTM A252umuyoboro urashobora kuba umutungo-mwinshi, ushobora gutera impungenge zijyanye no kuramba hamwe nibidukikije.
Gusaba
Mu bwubatsi n’ubwubatsi, guhitamo ibikoresho nibyingenzi kugirango habeho ubusugire no kuramba kwimiterere. Ikintu kimwe cyubahwa cyane mu nganda ni umuyoboro wa ASTM A252. Ibi bisobanuro bikubiyemo silindrike nominal urukuta rw'ibyuma biringaniye, nibyingenzi mubikorwa bitandukanye, cyane cyane mubuhanga bwububiko.
Ibisobanuro bya ASTM A252 bikurikizwa kubirundo byibyuma bikoreshwa nkabanyamuryango bahoraho bitwaje imitwaro cyangwa gukora igishishwa cyibikoresho bya beto. Ubu buryo butandukanye butuma bakoreshwa neza murufatiro rwimbitse, aho bashobora gushyigikira imitwaro iremereye no kurwanya imbaraga zuruhande. Imiyoboro iraboneka mubunini butandukanye, yemerera injeniyeri guhitamo ingano ikwiye hashingiwe kubisabwa byumushinga.
Porogaramu nyamukuru kuri ASTM A252 imiyoboro irimo ibiraro, inyubako, nizindi nyubako zisaba urufatiro rwimbitse. Ubushobozi bwabo bwo guhangana n’ibidukikije bikabije n’imitwaro iremereye bituma bahitamo neza ba injeniyeri naba rwiyemezamirimo. Mugihe dukomeje guhanga udushya no kunoza imikorere yinganda zacu, dukomeza kwiyemeza guha abakiriya bacu ibisubizo byizewe kandi biramba kugirango tubone ibyo bakeneye.
Ibibazo

Q2. Nibihe bikoresho bikoreshwa mu miyoboro ya ASTM A252?
Iyi miyoboro ikozwe cyane cyane mubyuma bya karubone, itanga igihe kirekire nimbaraga zo kwihanganira imitwaro iremereye hamwe n’ibidukikije bikabije.
Q3. Nigute umuyoboro wa ASTM A252 ukoreshwa mubwubatsi?
Imiyoboro ya ASTM A252 ikoreshwa kenshi mubikorwa byimbitse nkibiti byikiraro, kubaka urufatiro, no kugumana inkuta aho zitanga ubufasha bukenewe kandi butajegajega.
Q4. Haba hari icyemezo cya ASTM A252?
Nibyo, umuyoboro wa ASTM A252 wakozwe ukurikije amahame ya ASTM, ukemeza ko wujuje ubuziranenge n’imikorere.
