DHDZ ndiyo chiyero chenyika nevagadziri vemutsipa flange. Iyo kambani ine simba rakasimba rehunyanzvi, inokwanisa kugadzira nekugadzira akasiyana akakosha mataurirwo epombi akakodzera zvigadzirwa zvinoenderana nemushandisi zvinodiwa. Nekuongororwa kwemetallographic, kuyedza kwemuviri, kuongororwa kwemakemikari, kusaparadza kuyedza uye zvimwe zvepamberi zvekuyedza michina uye nzira.
Vagadziri veFlange vanonyanya kuita: gb neck flange, mutsipa flat welding flange, mutsipa butt welding flange, mitsipa isiri-standard flange uye mamwe marudzi emutsipa flanges. Ini chirimwa chine huwandu hukuru hwemapombi emuchina nyanzvi yevashandi vekumusana, yepamberi yekugadzira michina uye spectral metallography, kuona kukanganisa, kuongororwa kwemuviri uye kemikari uye imwe seti yakakwana yemidziyo yekuyedza, kambani inoteedzera yemhando yepamusoro manejimendi system. Yakavambwa yesainzi yemhando yekuvimbisa hurongwa, yakakwana yemhando yekusimbisa uye nesainzi kugadzira tekinoroji inonyatso kuvimbisa kunaka kwechigadzirwa.

DHDZ Flange vagadziri vanogadzira dhipatimendi rekutonga uye nzvimbo yekuyedza, ine yakakwira-kudzvanya pombi fittings uye yepakati uye yakaderera kumanikidza pombi fittings maviri ekuyedza masisitimu, mabasa ekuyedza akakwana, midziyo yekuyedza uye zviridzwa zviri munharaunda yepasirese neyepamba yepamusoro, Kune X- ray chikanganiso chekuonekwa, magineti cheki chikanganiso chekuonekwa, ultrasonic chikanganiso chekuonekwa, metallographic ongororo, kemikari bvunzo, mechanic chivakwa bvunzo, kukanganisa bvunzo, mvura yekumanikidza bvunzo, spectral bvunzo, infrared yekutarisa uye zvimwe zvinhu zvekuedza.
China gb neck flange vagadziri - kuhwina nemhando, purofiti diki asi inokurumidza kudzoka musimboti, inogara ichifambira mberi, mumakwikwi anotyisa emusika, nekubatana kwakanaka uye nemoyo wese sevhisi kuhwina ruzhinji rwevatengi kuvimba uye nekukurumidza kusimudzira. Kufambira mberi, kutsvaga kugona, kuenderera mberi nekudzidza, kusambogutsikana nekutenda kwevatengi vedu kugadzira kaviri kuhwina mamiriro, kugadzira ramangwana riri nani.
