Ibyiza byo gukoresha imiyoboro ya STELEL WELDEL ASTM A252
Imwe mu nyungu nyamukuru zo gukoresha ASTM A252 izengurutswe nicyuma cyuma nicyuma cyayo kinini kandi kiramba. Iyi miyoboro irashobora kwihanganira umuvuduko mwinshi n'imizigo iremereye, bigatuma iba nziza mu kohereza peteroli na gaze, gutwara amazi no gukoresha imiterere. Igikorwa cyo gusudira kizunguruka gikoreshwa mu musaruro gitanga imbaraga zikomeye ndetse n’ubumwe, bigatuma umuyoboro uhanganira ibidukikije bikaze.
Umutungo wa mashini
| Icyiciro cya 1 | Icyiciro cya 2 | Icyiciro cya 3 | |
| Gutanga umusaruro cyangwa gutanga imbaraga, min, Mpa (PSI) | 205 (30 000) | 240 (35 000) | 310 (45 000) |
| Imbaraga zingana, min, Mpa (PSI) | 345 (50 000) | 415 (60 000) | 455 (66 0000) |
Isesengura ry'ibicuruzwa
Icyuma ntigishobora kuba kirenze 0.050% fosifori.
Impinduka zemewe muburemere no mubipimo
Buri burebure bw'ikirundo cy'ipine bugomba gupimwa ukwe kandi uburemere bwacyo ntibushobora gutandukana hejuru ya 15% hejuru ya 5% cyangwa hejuru ya 5% munsi yuburemere bwacyo, ubaze ukoresheje uburebure bwacyo nuburemere bwacyo muburebure
Diameter yo hanze ntishobora gutandukana kurenza ± 1% uhereye kuri nomero yerekanwe hanze ya diameter
Umubyimba wurukuta umwanya uwariwo wose ntushobora kurenza 12.5% munsi yubugari bwurukuta
Uburebure
Uburebure bumwe butunguranye: 16 kugeza 25ft (4.88 kugeza 7,62m)
Uburebure bubiri bubiri: hejuru ya 25ft kugeza 35ft (7.62 kugeza 10.67m)
Uburebure bumwe: gutandukana byemewe ± 1in
Usibye imbaraga,imiyoboro y'icyuma izunguruka ASTM A252itanga uburyo bwiza bwo kurwanya ruswa. Ibi ni ingenzi cyane cyane ku miyoboro ihura n’ibidukikije bikabije cyangwa ibintu byangirika. Ipitingi ikingira iyi miyoboro irusheho kongera imbaraga zo kurwanya ruswa, bigatuma ubuzima bwa serivisi buramba hamwe nigiciro cyo kubungabunga.
Byongeye kandi, imiyoboro y'icyuma isudira mu buryo bwa ASTM A252 izwiho guhuza no koroshya kwishyiriraho. Igishushanyo cyoroshye gishobora guhindurwa byoroshye kugirango byuzuze ibisabwa byumushinga, mugihe imiterere yabyo yoroheje ituma gukora no gutwara byoroha. Ibi bituma bahitamo ikiguzi cyibikorwa bitandukanye, kuko bishobora gushyirwaho vuba kandi neza, bikagabanya umurimo nigihe cyo kubaka.
Iyindi nyungu yo gukoresha ASTM A252 izengurutswe nicyuma nicyuma kirambye cyibidukikije. Iyi miyoboro ikozwe mu bikoresho bisubirwamo, iyi miyoboro irashobora kongera gukoreshwa cyangwa gusubirwamo nyuma yubuzima bwabo bwingirakamaro, bikagabanya ingaruka rusange z’ibidukikije mu iyubakwa ry’imiyoboro no kuyitunganya. Byongeye kandi, igihe kirekire cyo kubaho hamwe nibisabwa bike byo kubungabunga bigira uruhare mubikorwa remezo birambye kandi bitangiza ibidukikije.
Mu gusoza, imiyoboro y'ibyuma isudira izunguruka ASTM A252 ifite urukurikirane rw'ibyiza bituma ihitamo bwa mbere mu kubaka imiyoboro. Imbaraga zabo nyinshi, kuramba, kurwanya ruswa, guhuza byinshi no kubungabunga ibidukikije bituma bakora neza mubikorwa bitandukanye mubikorwa bitandukanye. Muguhitamo iyi miyoboro, abategura umushinga barashobora kwemeza sisitemu yizewe kandi iramba yujuje ubuziranenge nibikorwa byiza.
