Musiyano pakati uoe nejcoe pipe

Yakakura-caliber, yakakwira dhizaini, madaro marefu ekufambisa uye akawanda marudzi ezvekufambisa epakati ndiyo chiratidzo chikuru chekufambira mberi kwetekinoroji indasitiri yepombi, asiwo maitiro akajairwa ekuvandudza indasitiri yepombi.Nekuvandudzwa kweindasitiri yemafuta eChina, mutsetse wegasi, mutsara wechipiri, uye mamwe mapurojekiti akakura arikuenderera mberi, dhayamita hombe, ukobvu hwemadziro epombi inotsikirira, inovandudza kudiwa.The chinyakare spiral musono welded pombi yave kutadza kuita zvinodiwa maererano kugona uye kuchengeteka kuita, hombe dhayamita, rusvingo ukobvu, yakakwirira giredhi LSAW nyere kutsiva spiral welded nyere yava isingadzivisiki muitiro.LSAW pombi yakavimbika yemhando, yakashandiswa zvakanyanya munyika dzekunze kwemafuta uye gasi repamusoro-voltage transmission trunk line.Mumakore achangopfuura, nyika ichaumbawo zvishoma nezvishoma LSAW pombi kugadzira kugona, mainstream pombi UOE tekinoroji uye JCOE yehunyanzvi.

Nekuvandudzwa kwegiredhi resimbi, kuvakwa kwepombi, musono wakatwasuka wakanyudzwa arc welded pombi kuti ive sarudzo yekutanga yeakawanda emutsetse wehunde, kunyanya munzvimbo yakaoma yakasikwa, iyo pombi yegungwa ine vanhu vakawanda."West-East Gas Pipeline Project, yemhando mbiri, nhatu, ina dzemhando dzakakura dzakatwasuka dzakanyura arc welded pombi, 14% inogadzirwa JCOE chubhu, uye imwe yese inotengeswa kunze kweUOE pombi.

Kugadzirwa kweUOE neJCOE, kusiyana kwakasiyana kwechigadzirwa

Maonero kubva kune maviri maitiro ekugadzira, ese ari mukugadzira kumberi nekumashure kwakangofanana, musiyano mukuru ndewekuti nzira yekuumba.Iyo UOE kuumba inonyanya kuve nematanho maviri: iyo U kugadzira uye O kuumba.Uye JCOE ichiita chikamu chechirongwa chakakamurwa kuita zvikamu zvitanhatu, kushanda kwekugadzira kwakaderedzwa zvakanyanya.Kugadzira nzira dzakasiyana, inotungamira kune iyo UOE neJCOE misiyano mudhayamita, ukobvu hwemadziro, hukuru, kugona kwekugadzira, goho reshiyo.

Iyo UOE mutsetse pombi uye JCOE yepombi pombi kubva pakuenzanisa kuongororwa kwemaitiro ekugadzira uye mutengo wekugadzira, zvinotevera mhedzisiro:

(1) UOE kugadzirwa kwehunyanzvi, kugona, uye kutsiva kweiyo mold yakareba nguva, yakakodzera kugadzirwa

(1) UOE kugadzirwa kwehunyanzvi, kugona, uye kutsiva kwe mold kwenguva yakareba, yakanyatsokodzera kugadzirwa kwehuwandu hukuru, chigadzirwa chechinhu chimwe chete;kugadzirwa kusinganyanyi kushanda zvakanaka JCOE, mold inoenderana neyakasiyana-siyana, yakanyatsokodzera kugadzirwa kwevhoriyamu diki, yakawanda-yakatarwa zvigadzirwa.

(2) iyo UOE inogadzira zvigadzirwa dhayamita renji uye ukobvu huwandu hunofanirwa kunge husingasviki JCOE, asi hunokwanisa zvizere kuzadzisa zvinodiwa zvepurojekiti.

(3) Kubva pakuona kwekuita, UOE mutsetse pombi yakaenzanisa JCOE vane residual stress, yakakwirira nemazvo Dimensions goho zvakanakira pane diki.
