ASTM A53bisanzwe ni Sosiyete y'Abanyamerika ishinzwe ibizamini n'ibikoresho. Igipimo gikubiyemo ubunini butandukanye bwubunini nubunini kandi bukoreshwa kuri sisitemu yo gukoresha imiyoboro ikoreshwa mu gutwara gaze, amazi nandi mazi. Imiyoboro isanzwe ya ASTM A53 ikoreshwa cyane mu nganda n’ubukanishi, ndetse no mu nganda zubaka mu gutanga amazi, gushyushya no guhumeka.

UkurikijeASTM A53bisanzwe, imiyoboro irashobora kugabanywamo ubwoko bubiri: Ubwoko F na Ubwoko E. Ubwoko F ni umuyoboro udafite icyerekezo naho ubwoko bwa E ni umuyoboro w'amashanyarazi. Ubwoko bwombi bwimiyoboro isaba kuvura ubushyuhe kugirango imiterere yimashini hamwe nibigize imiti byujuje ibisabwa bisanzwe. Byongeye kandi, ibisabwa hejuru yu muyoboro bigomba kubahiriza ibiteganijwe muri ASTM A530 / A530M kugirango bigaragare neza.

Ibigize imiti isabwa mu miyoboro isanzwe ya ASTM A53 ni ibi bikurikira: ibirimo karubone ntibirenza 0,30%, ibirungo bya manganese ntibirenza 1,20%, ibirimo fosifore ntibirenza 0,05%, ibirimo sulferi ntibirenza 0.045%, ibirimo chromium ntibirenza 0,40%, hamwe na nikel ntabwo irenga 0.40%, ibirimo umuringa ntibirenza 0.40%. Izi miti igabanya imiti itanga imbaraga, ubukana hamwe na ruswa irwanya umuyoboro.

Kubireba imiterere yubukanishi, ASTM A53 isanzwe isaba ko imbaraga zingana nimbaraga zitanga imiyoboro itari munsi ya 330MPa na 205MPa. Byongeye kandi, umuvuduko wo kurambura umuyoboro nawo ufite ibyo usabwa kugirango umenye neza ko udakunda kumeneka cyangwa guhinduka mugihe cyo gukoresha.

Usibye imiterere yimiti nubukanishi, igipimo cya ASTM A53 gitanga kandi amabwiriza arambuye kubijyanye nubunini nubwiza bwimiyoboro. Ingano yimiyoboro iri hagati ya 1/8 na santimetero 26, hamwe nuburyo butandukanye bwurukuta. Ubwiza bugaragara bwumuyoboro busaba ubuso bunoze nta okiside igaragara, ibice ndetse nudusembwa kugirango tumenye ko bitazatemba cyangwa ngo byangiritse mugihe cyo kwishyiriraho no gukoresha.

Muri rusange, igipimo cya ASTM A53 nigipimo cyingenzi kumiyoboro yicyuma. Ikubiyemo ibisabwa mubigize imiti, imiterere yubukanishi, ibipimo nubwiza bwimiterere yimiyoboro. Imiyoboro yakozwe ikurikije iki gipimo irashobora kwemeza ubuziranenge buhamye kandi bwizewe, kandi ikwiranye na sisitemu yo kuvoma munganda zitandukanye nubwubatsi. Gutegura no gushyira mu bikorwa ibipimo bya ASTM A53 bifite akamaro kanini mu kurinda umutekano w’imiyoboro no guteza imbere ubwubatsi bw’imishinga.
