Valve ya AWWA Butterfly DN1000 yatanzwe mu mushinga wo gukonjesha Umunara muri Arabiya Sawudite

Incamake y'ibicuruzwa

Nortech Engineering Corporation yarangije gutanga units 37 za valve y’ibinyugunyugu ifite flange ebyiri yagenewe AWWA C207 Class B. Valve zifite ingano ya DN1000 (santimetero 40) ifite umuvuduko wa psi 150 (PN10). Igice cy’iyi valve cyakozwe mu cyuma gikozwe mu cyuma gikozwe mu cyuma gikozwe mu buryo bwa ductile, kandi igishushanyo gikurikiza imiterere y’ihuza ry’impande ebyiri kugira ngo ihuzwe neza n’imiyoboro ya AWWA.

Ubu buryo bwo kohereza bugaragaza ko twatumije uburebure bunini bwakozwe n'uruganda rwacu rwa double flange butterfly valves kandi bugaragaza ubushobozi bwacu bwo gukora imishinga myinshi kandi ifite imiterere myinshi ku gihe.

Ibisobanuro bya tekiniki

Disiki n'igitereko byakozwe mu cyuma gikozwe mu cyuma kitagira umugese gifite urwego rwa 2507 (UNS S32750), cyatoranijwe kubera ko gifite ubushobozi bwo kurwanya ibitugu, kwangirika kw'imirongo, no kwangirika kw'imitsi ya chloride. Intebe ikoresha EPDM ikora neza kugira ngo ikomeze kuzimya umuvuduko wose. Buri vali ifite agakoresho gakoresha intoki gapima umuvuduko kangana n'agace ka DN1000.

Sisitemu yo gusiga irangi hanze ikurikiza ISO 12944 Classification CX-H, icyiciro cyo gukomera cyane cyagenwe mu nganda no mu nyanja byangiza cyane. Iyi mbonerahamwe y'irangi ihamya ko amarangi aramba aho gusiga irangi bisanzwe byananirwa mbere y'igihe bitewe n'ubushyuhe, ubushuhe, n'imiti.

Gusaba no Gutanga

Izi mashini zikora neza zo mu bwoko bwa "double flanged butterfly valves" zigenewe umushinga wo gukonjesha mu Bwami bwa Arabiya Sawudite. Imashini zikora mu karere ka Gulf zikorerwamo ubushyuhe bwinshi, ubushuhe bwinshi, n'ibinyabutabire by'amazi bikaze, bigatuma guhuza ibikoresho bya "duplex 2507" na "ISO 12944 CX-H coating" biba ingenzi cyane kugira ngo imitungo irambe. Igipimo cy'umuvuduko wa AWWA C207 Class B gihuye n'imiyoboro minini y'amazi ikoreshwa mu buryo busanzwe mu nganda zikonjesha muri ako karere.

Nortech ni uruganda rukora valve z'ibinyugunyugu rufite uburambe mu kohereza ibicuruzwa mu Burasirazuba bwo Hagati, rutanga valve nini za AWWA zo gukoresha mu gutunganya amazi, gukuramo umunyu, no gukonjesha mu nganda.
