ASTM A501 Icyiciro B.ni icyuma gishyushye gisudira kandi kidafite icyuma cya karubone gifite imbaraga byibura zingana na 448 MPa (65.000 psi) kubikorwa bitandukanye byubaka.
ASTM A501ni kubihimbano no gukora bishyushye-byashushanijwe kandi bidafite icyerekezo cya karubone ibyuma byubaka.
Imiyoboro yicyuma irashobora kuba umukara (idatwikiriwe) cyangwa igashyuha-yashushe cyane, iyanyuma ikaba yarongereye imbaraga zo kurwanya ruswa binyuze murwego rwo gusya, bigatuma ikwiranye n’ibidukikije byinshi.
Iyi miyoboro yicyuma ikoreshwa cyane mubiraro, inyubako, nibindi bikorwa rusange byubatswe.
ASTM A501 ishyira umuyoboro wibyuma mubyiciro bitatu,icyiciro A, icyiciro B, n'icyiciro C..
Icyiciro B nicyo gikoreshwa cyane mubyiciro bitatu kuko gitanga imitungo iringaniye kubintu byinshi byubaka.
Icyuma kizakorwa nashingiro-ogisijeni cyangwa amashanyarazi-arc-itanura inzira yo gukora ibyuma.
Ibyuma birashobora guterwa mungingo cyangwa birashobora guterwa.
Iyo ibyuma byo mu byiciro bitandukanye bikurikiranye bikurikiranye, uwakoze ibyuma agomba kwerekana ibikoresho byahindutse hanyuma akabikuraho akoresheje uburyo bwashyizweho butandukanya neza amanota.
Igituba kizakorwa nimwe mubikorwa bikurikira:nta nkomyi;itanura-butt-gusudira (gusudira bikomeje);gusudira amashanyarazi (ERW) cyangwa gusudira arc gusudira (SAW)hakurikiraho gushyuha mugice cyambukiranya no gushyuha muburyo bwo kugabanya cyangwa gushiraho, cyangwa byombi.
Gahunda yo gusudira SAW igabanijwemoLSAW(SAWL) na SSAW (HSAW).
Imiterere yanyuma igomba gukorwa nuburyo bushyushye.
Biremewe kongeramo ubushyuhe busanzwe bwo kuvura igituba gifite uburebure bwurukuta burenze 13mm [1/2 muri].
