ASTM A131 AH32 DH32 EH32 FH32 Icyuma cyubaka ubwato

Icyuma cyo mu nyanja bivuga ibyuma byubatswe bikoreshwa mu kubaka ubwato. Bifatwa nk'urwego rwo mu nyanja kandi rugomba kuba rushobora kurwanya ingaruka mbi zangiza ibidukikije. Kugirango ubigereho, ibintu bidasanzwe bivanga byongewe kuri aya manota murwego rwo kurinda ruswa ya agaist.Mu gihe ibyuma byinshi bya karubone bidakwiranye n’ibidukikije byo mu nyanja, hari ibyuma byinshi byo mu nyanja byo mu nyanja byemejwe n’imiryango itandukanye yo kubaka ubwato.

Ibyuma byubatswe kubwato bigabanijwemo ibyiciro byimbaraga ukurikije imbaraga zabyo nkeya: imbaraga rusange zubaka ibyuma hamwe nimbaraga zikomeye zubaka. Icyuma cya Maine bivuga icyuma gishyushye kizengurutse cyakozwe hakurikijwe ibisabwa na societe ya classique yo kubaka inyubako zubwato. Imbaraga rusange zibyuma bya societe yubushinwa igabanijwemo ibyiciro bine byujuje ubuziranenge: A B D na E.

Ubwato bunini butangirira ku cyuma cyiza cyo mu rwego rwo hejuru kandi Gnee yishimiye guha inganda zo muri Amerika kubaka ubwato hamwe n’ibyuma byo mu nyanja n’inyanja birwanya ruswa kandi bikomeye, byerekana ko ubukana bwagabanutse, ndetse no mu bushyuhe bukonje, kandi byongera imbaraga zo kurwanya ihungabana ry’ingufu kandi kunyeganyega. Ibyapa byacu byose byo mu nyanja byujuje ubuziranenge bwashyizweho na ABS (Ikigo cy’Abanyamerika gishinzwe ubwubatsi), ASTM, na API (Ikigo cya Amerika gishinzwe peteroli). Turi abatanga ibyiringiro byo gutanga ibyuma bya marine & offshore ibyuma kwisi yose hamwe nabubaka ubwato
