Yakagadzirwa muChina Kuchenesa midziyo yakakwira kudzvanya kuchenesa Pipeline Nguruve

Pane zvikonzero zvitatu zvekuvharira chubhu:

Kutanga, pombi yacho inoremara zvakakomba zvokuti nguruve haigoni kupfuura;

Chechipiri, pombi yakaderera-yakarara tsvina uye yakawanda yetsvina inobviswa zvakanyanya kuita kuti pamberi penguruve ivhare;

Chechitatu, mukuita kwemuviri mukuru wekunze kana perforation punch kadhi yakaoma pane zvinhu zvinopinda muchubhu.

Mhinduro ndeiyi inotevera:

1.

Pipeline deformation.Inoreva pombi kana gokora nekuda kwekushushikana kana kwekunze kunokonzerwa nedeformation inodarika 15%.Solution:nguruve yekuchenesa nyoropachayo deformation ye45%, chero bedzi iyo pombi deformation isingapfuuri 40%, haisi iyo chiitiko chekuvhara.Kana kadhi plug, mumaawa maviri kusvika matatu kuwana nzvimbo yakavharika nekukurumidza, ine buri rekumanikidza kubvisa nguruve, tsiva iyo deformation pombi kuti ienderere mberi yakajeka.

2.

Pipeline waxing tsvina deposition.Mberi yenguruve deposition yakanyanya kureba, mhinduro: kudzora kwakasimba kwenhamba yetsvina.Kushandiswa kwenguruve yakapfava dhayamita kubva kudiki kusvika kuhombe, nhanho nhanho nzira, kuitira kuti nguva imwe neimwe chubhu ine mwero huwandu hwegirisi kuvandudza kugona kwenguruve, kudzivirira nguruve kuvharika, senge yakawandisa deposition inokonzera kuwedzera kumanikidza, gomba rine dzvinyiriro yekuregererwa kwechidimbu (muchubhu isati yasvika 300m, kuvhura kana kufanochekwa mupombi panzvimbo yekuvhura, saizi yegomba Φ90 ~ Φ100).

3.

Kana iyo yekune imwe nyika plug, mumaawa maviri kusvika ku3 kuti uwane nzvimbo yekuvharira nekukurumidza, nekumanikidza block off, bvisa nguruve, bvisa mutumbi wekunze kuti urambe uchichenesa.
