Lenonyeletso la monolithic insulating ke lebitso le akaretsang la lenonyeletso le ka nkang sebaka sa ho kenellaflange'me e na le ts'ebetso ea ho tiisa e hlokoang ke phala ea tšepe e patiloeng le ts'ebetso ea ho kenya motlakase e hlokoang ke boenjiniere ba ts'ireletso ea kutu.Mohlala oa lisebelisoa o na le likarolo tse peli tse hokelang ka hare le kantle, le seaparo se tiisang se tiisang bohareng ba karolo e kopanyang le liphaephe tse peli tse khutšoane tsa tšepe tse cheselitsoeng ka karolo e hokelang ka ho latellana.Ke karolo ea bohlokoa bakeng sa ts'ireletso ea cathodic ea lipeipi lipalangoang tsa liphaephe e le ho thibela ho bola ha electrochemical.E na le boima bo phahameng ho feta flange ea insulation, e ka mamella nako e kholo ea ho kobeha, ts'ebetso e phahameng ea ho kenya letsoho, bophelo bo bolelele, 'me e ka patoa ho kenngoeng.

Monolithic insulating joint e entsoe ka likarolo tse latelang: phala e ka holimo, phala e ka tlaase, sleeve, likarolo tse sireletsang, likarolo tsa ho tiisa, ho roala ha metsi.Ho na le likarolo tse sireletsang le likarolo tsa ho tiisa liphaepheng tse ka holimo le tse ka tlaase tsa likarolo tse qetellang tsa li-insulation butt, tse etsang mohaho oa ho tiisa habeli o nang le ts'ebetso ea ho pata.Mokotla o amohela welding ea groove kapa welding e otlolohileng ka kotopo e kaholimo.Likarolo tse sireletsang le liphaephe tse ka holimo le tse ka tlaase li tiisitsoe ka thata ka hare ho etsa "sejana se tiisitsoeng", se nang le phello e ntle ea ho thibela metsi feela, empa hape se ntlafatsa haholo matla a ho jara a sebopeho sa insulating.

Lisebelisoa

1. Thepa ea tšepe ea motsoako oa ho kenya letsoho e tla ba tšepe e bolailoeng e qhibilihisitsoeng ka sebōpi sa motlakase kapa mochine oa oksijene, 'me tšepe e qhibilihisitsoeng ka mocheso o ka tlaase ho -20 ° C e tla hloekisoa ka ntle ho sebōpi.

2.Litlhoko tsa tekheniki tsa tšepe li lokela ho finyella litlhoko tsa moralo oa lefapha la moralo oa boenjiniere oa liphaephe.

3.Tšepe e sebelisoang bakeng sa tlhahiso e kopanetsoeng ea ho kenya letsoho e tla ba le setifikeiti sa boleng, 'me moetsi oa motsoako o kenang o tla hlahloba le ho amohela tšepe ho latela setifikeiti sa boleng.

4. Forgings e sebelisetsoang likarolo tsa compression e tla lumellana le NB/T 47008 le NB/T 47009.

5.Forgings e sebelisetsoang likarolo tsa compression e lokela ho khethoa ho ea ka khatello ea moralo, boima le boholo.

Libaka tsa kopo

Tekanyetso ena e sebetsa ho manonyeletso a monolithic a nang le bophara bo sa feteng 600mm le khatello ea moralo e sa feteng 16MPa le bophara bo sa feteng 1400mm le khatello ea moralo e sa feteng 12MPa, e bitsoang insulating. manonyeletso, boenjiniere ba ts'ireletso ea kutu ea motlakase ea liphaephe tsa tšepe tsa lipalangoang tse patiloeng kapa tse ka holimo ho fatše tsa peterole le khase ea tlhaho.Moetso oa eona o sebetsang oa mocheso o fapaneng ke -45 ℃ ~ 100 ℃.

Lisebelisoa tsa boleng

Matla a insulation: 2500V 50Hz motsotso o le mong ha ho na ho senyeha kapa arc;

Insulation resistance: DC 1000V ho hanyetsa ≥6M ω;

Khatello ea tlhahlobo ea Hydrostatic: Linako tse 1.5 tsa khatello ea moralo;

Khatello ea teko ea moea: e lekanang le khatello ea moralo;

Teko e sa senyeheng: ho latela JB4730-94, manonyeletso ohle a butt ke tlhahlobo ea radiographic ea 100%, 'me li-welds tse ling kaofela ke 100% tlhahlobo ea likaroloana tsa makenete;

Groove: amohela maemo a API5L.

Lisebelisoa tsa ho kenya

1. Qoba ho tjheseletsa ka hare ho dimithara tse 50 ho tloha ho kenngwa ha manonyeletso;

2. Ka mor'a ho kopanya motsoako oa ho kenya letsoho le pipeline, u se ke ua phahamisa pipeline ka har'a limithara tse 5 ho tloha ho kopane;

3. Teko ea khatello ea motsoako oa ho kenya letsoho le sesebelisoa sa pipeline.
