    Ibirango by'ibicuruzwa

    Muri Cangzhou Spiral Steel Pipes Group Co., Ltd., twishimiye cyane kwerekana iterambere ryacu rigezweho mu nganda z'imiyoboro y'ibyuma -Umuyoboro wa SSAWIki gikoresho gishya gihuza ikoranabuhanga rigezweho n'ubuhanga budasanzwe kugira ngo gitange ibisubizo biboneye ku bikorwa bitandukanye.

    Umuyoboro wa SSAW niumuyoboro ushongeshejwe ku buryo bw'uruzigaikozwe mu byuma by'ubudodo byo mu bwoko bwa strip coils. Dukoresha ikoranabuhanga rigezweho ryo gusohora kugira ngo dukomeze ubushyuhe mu gihe cyose cyo gukora, hanyuma tugakoresha uburyo bwo gusudira arc bukozwe mu buryo bwikora. Ubu buryo bugezweho butuma habaho gufatana gukomeye kandi kurambye, bigatuma umuyoboro ukomeye kandi wizewe.

    Imwe mu nyungu zikomeye zoumuyoboro ushongeshejwe ku buryo bw'uruzigani imbaraga zayo zihebuje, zirenze iz'umuyoboro ugororotse. Ibi bituma iba nziza ku mishinga isaba ubuziranenge bw'inyubako. Byongeye kandi, bitewe n'uburyo ikora, umuyoboro ukozwe mu buryo bw'uruziga ushobora gukorwa hakoreshejwe ibyuma bito, bigatuma habaho imiyoboro minini. Byongeye kandi, dukoresheje utudomo tw'ubugari bumwe, dushobora gukora imiyoboro y'ubugari butandukanye mu buryo bworoshye, turushaho kwagura imikorere yayo.

    Umuyoboro wa SSAW

    Kubera ubwitange bukomeye mu ireme, ikigo cyacu cyashoye amafaranga menshi mu gushyiraho inganda zigezweho. Iyi sosiyete ifite ubuso bwa metero kare 350.000 kandi ifite umutungo wa miliyoni 680 z'amayuani. Ariko ikidutandukanya by'ukuri ni itsinda ryacu ryitanze. Abakozi bacu b'abahanga 680 bafite ubumenyi buhanitse ni bo batumye tugera ku ntsinzi.

    Twishimiye ubushobozi bwacu bwo gukora toni 400.000 z'imiyoboro y'ibyuma bizunguruka buri mwaka, birenga ku rwego rw'inganda. Uyu musaruro udasanzwe watanze umusaruro mwinshi cyane wa miliyari 1.8 z'amayuani. Itsinda ryacu ryizeza ko buri gikoresho kiva mu kigo cyacu gikurikiza ingamba zikomeye zo kugenzura ubuziranenge, bigatuma abakiriya bacu bagira ubuziranenge buhebuje.

    Muri make, imiyoboro ikoze mu cyuma ihindura imikorere y’inganda z’imiyoboro y’icyuma. Kubera imbaraga zayo zidasanzwe, ubushobozi bwayo bwo gukora ibintu bitandukanye kandi ikaba yizewe cyane, ni yo gisubizo cy’ibanze ku byo ukeneye byose mu miyoboro ikoze mu cyuma. Fatanya na Cangzhou Spiral Steel Pipes Group Co., Ltd. uyu munsi kugira ngo umenye ahazaza h’inganda z’imiyoboro y’icyuma.
