S355 jr spiral steel pieImbaraga NO
S355 jr spiral steel pieikorerwa gukoresha ikoranabuhanga rigezweho hamwe nicyuma cyiza-cyo guhuza imbaraga no kunyuranya mubicuruzwa bimwe. Iyi miyoboro yagenewe kwihanganira imikazo ikabije, bigatuma bikwiranye nuburyo butandukanye. Byakoreshwa mu gutwara amazi, amavuta cyangwa gaze karemano, iyi miyoboro itanga imikorere idahwitse kandi iramba.
Imiterere ikomeye hamwe nubunyangamugayo
Kimwe mu bintu bifatika bya S355 jr umuyoboro w'icyuma ni ubwubatsi bukomeye, butuma ubunyangamugayo. Iyi miyoboro irerekana ingamba zo kuzunguruka zemeza imbaraga ntarengwa mugihe zigabanya ibyago byo kumeneka cyangwa gutsindwa. Iki gishushanyo cyimbere gifasha umuyoboro kugirango uhangane nibihe biremereye kandi bikaze ikirere, bigatuma ari byiza kubikorwa remezo bikomeye nkibiraro, tunel n'inyubako ndende.

Irwanya ibintu byangiza kandi ibidukikije
Mu mushinga uwo ari wo wose wo kubaka, kuramba no kwizerwa cyibikoresho ni ngombwa. S355 JR Imiyoboro ya Spiral Stel muriyi ngingo nkuko barwana cyane nibibazo byorora kandi biteye ibidukikije. Icyuma cyakoreshejwe mu musaruro ufatwa bidasanzwe kugirango wongere kurwanya, bigatuma iyi miyoboro ibereye hejuru- no munsi yubutaka. Uku kurwanya gusa imbere ubusugire bwumuyoboro, ariko nanone kugabanya ibiciro byo kubungabunga, kubigira inzira nziza.
Kongera irambye kandi urugwiro
Guhura nibibazo byisi yose bijyanye n'imihindagurikire y'ikirere no ku bijyanye n'ibidukikije, inganda zubaka zirashaka cyane ibisubizo birambye. S355 JRumuyoboro wa spiralirakoreshwa cyane kandi ikagira uruhare muri ubwo buryo burambye. Iyi miyoboro irashobora gusubirwamo kandi igakoreshwa, kugabanya imyanda no kubungabunga umutungo kamere. Byongeye kandi, ubuzima bwabo burebure bugabanya cyane gusimburwa, gukomeza kugabanya ibidukikije muri rusange.
Gukurikiza ibipimo ngenderwaho
S355 jr umuyoboro w'icyuma wakozwe neza ukurikije ibipimo bikomeye. Ibi birabyemeza ko buri pipe ikora neza kandi yubahirizwa n'amabwiriza asabwa. Yaba ari imishinga ikomeye nka fapeline ya peteroli na gaze, iyi miyoboro itanga kwizerwa, kwiringirwa namahoro yo mumitekerereze n'amahoro yo mumitekerereze, abashoramari na ba nyir'umushinga.
Mu gusoza
Kugira ngo uvuze, S355 jr umuyoboro w'icyuma wabaye igice cyingenzi mubikorwa remezo bigezweho kubera imbaraga zayo zisumba izindi, kunyuranya no gukora muri rusange. Kubakwa ubushishozi, kurwanya ruswa no kubahiriza ibipimo byiza bituma bigira intego yimishinga itandukanye. Byongeye kandi, kuramba kwabo na eco-nshuti byongera agaciro kandi bigatanga umusanzu mubizaza. Mugihe dukomeje guharanira iterambere mu nganda zubwubatsi, biragaragara ko S355 jr umuyoboro w'icyuma utemba uzakomeza kugira uruhare runini mu guhindura isi tubamo.
