Umuyoboro w'icyuma udafite umugozi wa ASTM A53ishyirwa mu cyiciro cya A53 Type S kandi ni umuyoboro w'icyuma udakora neza.
Igabanyijemo ibice bibiri, Icyiciro cya A n'icya B, kandi ikwiriye gukoreshwa mu buryo bwa mekanike n'umuvuduko, ndetse no gukoreshwa muri rusange mu mwuka w'umwuka, amazi, gazi n'umwuka. Uyu muyoboro w'icyuma ni umuyoboro w'icyuma cya karuboni ukwiriye gukoreshwa mu gusudira no gukora harimo guhuza imiyoboro, kuyigonda no kuyihuza n'ibice by'urukiramende.

Mu by’ukuri, Ingengo ya 40 na Ingengo ya 80 ni byo bipimo bibiri by’ubugari bw’inkuta z’imiyoboro bikoreshwa cyane. Kugira ngo umenye byinshi, rebaTeganya amanota ya PDFdosiye dutanga.
Kuva yashingwa mu 2014,Botop Steelyabaye ikigo gikomeye mu kugurisha imiyoboro y'icyuma cya karuboni mu majyaruguru y'Ubushinwa, kizwiho gutanga serivisi nziza, ibicuruzwa byiza, n'ibisubizo byuzuye.
Iyi kompanyi itanga imiyoboro itandukanye y’icyuma cya karuboni n’ibindi bifitanye isano, birimo imiyoboro y’icyuma idakora neza, ERW, LSAW, na SSAW, ndetse n’urutonde rwuzuye rw’imiyoboro n’ibice bifunganye. Ibicuruzwa byayo byihariye birimo kandi alloys nziza n’ibyuma bitarangirika bya austenitic, byakozwe kugira ngo bihuze n’ibikenewe mu mishinga itandukanye y’imiyoboro.
Imiyoboro y'icyuma ya ASTM A53 ishobora kuba idafunze cyangwa idasuzumwe.
Uburyo bwo gukora budafite umugozi (Type S) ni ugukoresha icyuma gishyushye, kandi byaba ngombwa, kurangiza neza igicuruzwa gishyushye kugira ngo kigere ku ishusho, ingano, n'imiterere bikenewe.
Mu gipimo cya ASTM A53, ibisabwa ku miterere y'imiti yo mu bwoko bwa S naUbwoko Eimiyoboro y'icyuma ni imwe, mu gihe ibisabwa mu miterere y'imiti yo mu bwoko bwa F bitandukanye.

Ikizamini cyo Kunama
Kuri DN ≤ 50 [NPS ≤ 2], uburebure buhagije bw'umuyoboro bugomba kuba bushobora kunama bukonje bunyuze kuri dogere 90 hirya no hino ku giti cy'umugozi, gifite umurambararo ukubye inshuro cumi n'ebyiri z'umurambararo wo hanze wagenwe n'umuyoboro, nta gucikamo ibice.
Ingufu ebyiri cyane(XXS) umuyoboro urenga DN 32 [NPS 1 1/4] ntugomba gukorerwa isuzuma ry’uko ugenda.
Ikizamini cyo Kugorora
Imiyoboro y'icyuma idafite umushono ntabwo ikenewe gukorerwa ikizamini cyo kugorora.
Iyo amasezerano abisabye, igerageza rishobora gukorwa hakurikijwe inzira iri muri S1.
Ingano zose z'imiyoboro y'icyuma idakora neza zigomba kugumana igipimo runaka cy'umuvuduko w'amazi nta gusohoka byibuze mu gihe cy'amasegonda atanu.
Igitutu cy'igerageza ku miyoboro y'icyuma isanzwe kiboneka mu mbonerahamwe ya X2.2.
Imiterere y'ibipimo ku miyoboro y'icyuma ifite insinga n'iy'ibyuma ifatanye iboneka mu mbonerahamwe ya X2.3.
Ishobora gukoreshwa nk'uburyo bwo gusimbura ikizamini cya hydrostatic.
Uburebure bwose bwa buri muyoboro udafite umugozi bugomba gupimwa amashanyarazi adasenya hakurikijweE213, E309cyangwaE570.
Mu gihe uguze ASTM A53, ubushobozi bwo kwihanganira ingano y'umuyoboro w'icyuma bugomba kuba bwujuje ibi bikurikira.

Amabwiriza ya ASTM A53 agaragaza ibisabwa kugira ngo imiyoboro y'umukara ibeho ndetse n'aho imiyoboro y'icyuma ishyushye itwikiriwe.
Umuyoboro w'umukara
Umuyoboro w'umukara yerekeza ku miterere y'umuyoboro w'icyuma udakoresheje uburyo ubwo ari bwo bwose bwo gutunganya ubuso.
Imiyoboro y'umukara ikunze gukoreshwa ahantu igihe cyo kubika ari gito, ibidukikije byumye kandi bitangiza, kandi igiciro gisanzwe kiba kiri hasi kuko nta gipfundikizo gihari.
Igipfundikizo cya galvanize gishyushye
Imiyoboro ya galvani, izwi kandi ku izina ry'imiyoboro yera, ikunze gukoreshwa ahantu hakonje cyangwa hangiritse.
Zinc iri mu gipfundikizo cya zinc ishobora kuba ubwoko ubwo aribwo bwose bwa zinc muri ASTM B6.
Umuyoboro wa galvanize ugomba kuba udafite ahantu hatapfutse, udusebe, imyanda, n'imyanda yose. Ibibyimba, imiterere, utubumbe, cyangwa imyanda myinshi ya zinc bizabangamira ikoreshwa ry'ibikoresho riteganyijwe ntibyemewe.
Ingano ya zinc ntabwo iri munsi ya 0.55 kg / m² [1.8 oz / ft²].
Izindi mpapuro zo kwambara
Uretse imiyoboro y'umukara n'iy'icyuma gikingira, ubwoko busanzwe bwo gusigamo harimoirangi, 3LPE, FBE, n'ibindi. Ubwoko bw'igitambaro bukwiye bushobora gutoranywa hakurikijwe ibisabwa byihariye by'aho imikorere ibera.
Gutanga amakuru akurikira bizatuma uburyo bwo kugura ibintu bwawe burushaho kuba bwiza kandi bunoze.
