I-Monolithic Insulating Joint One Piece Insulating Joint A694 F70

Isingeniso Somkhiqizo

Ijoyinti le-monolithic insulating yigama elijwayelekile lejoyinti elingangena esikhundleni sokufakwa esikhundlenii-flangefuthi inakho kokubili ukusebenza kokuvala okudingekayo ngamapayipi ensimbi agqitshiwe kanye nokusebenza kukagesi okudingwa ubunjiniyela bokuvikela ukugqwala kukagesi.Imodeli yensiza ihlanganisa izingxenye ezimbili ezixhumeneyo zangaphakathi nezangaphandle, kanye nejazi lophawu elivikelayo eliphakathi nendawo yokuxhuma kanye nepheya lamapayipi amafushane ensimbi ashiselwe nengxenye yokuxhuma ngokulandelanayo.Kuyingxenye ebalulekile yokuvikela i-cathodic yepayipi ekuthuthweni kwepayipi ukuze kuvinjwe ukugqwala kwe-electrochemical.Inokuqina okuphakeme kune-insulation flange, ingathwala isikhathi esikhulu sokugoba, ukusebenza okuphezulu kokufakwa, impilo ende, futhi ingangcwatshwa ekufakweni.

I-monolithic insulating joint yakhiwa izingxenye ezilandelayo: ipayipi elingaphezulu, ipayipi eliphansi, umkhono, izingxenye zokuvikela, izingxenye zokuvala, i-insulating coating.Kunezingxenye ezivikelayo kanye nezingxenye zokuvala emapayipini angaphezulu naphansi ezingxenye zokugcina zezinqe ezihlanganyelwe, ezakha isakhiwo sokuvala kabili esisebenza ngokufaka ukufakwa.Umkhono usebenzisa i-groove welding noma i-welding eqondile ngomsele ongaphezulu.Izingxenye ze-insulating kanye namapayipi angaphezulu naphansi avaliwe ngokuqinile ngaphakathi ukuze enze "isitsha esivaliwe", esingenawo umphumela omuhle wokuvikela, kodwa futhi sithuthukisa kakhulu umthamo wokuthwala wesakhiwo se-insulating.

Izinto zokwakha

1.Impahla yensimbi yejoyinti lokugqumisa kuyoba insimbi ebulewe encibilikiswe yisithando somlilo sikagesi noma isiguquli se-oxygen, futhi insimbi encibilikisiwe ekushiseni okungaphansi kuka -20°C izocwengwa ngaphandle kwesithando somlilo.

I-2.Izidingo zobuchwepheshe zensimbi kufanele zihlangabezane nezidingo zokuklama zomnyango ofanele wokuklama ubunjiniyela bepayipi.

3.Insimbi esetshenziselwa ukwakhiwa okuhlangene kokufakwayo izoba nesitifiketi sekhwalithi, futhi umkhiqizi wejoyinti lokwahlukanisa kufanele ahlole futhi amukele insimbi ngokuvumelana nesitifiketi sekhwalithi.

4.Ama-Forging asetshenziselwa izakhi zokucindezela kufanele ahambisane ne-NB/T 47008 kanye ne-NB/T 47009.

I-5.Forgings esetshenziselwa izingxenye zokucindezela kufanele ikhethwe ngokuvumelana nokucindezela kokuklama, isisindo nobukhulu.

Izinkambu zesicelo

Leli zinga lisebenza kumajoyinti avikelayo e-monolithic anobubanzi obungadluli ku-600mm kanye nengcindezi yokuklama engeqile ku-16MPa kanye nobubanzi obujwayelekile obungeqile ku-1400mm kanye nengcindezi yokuklama engeqile ku-12MPa, okubhekiselwa kuyo njenge-insulating. amajoyinti, kubunjiniyela bokuvikela ukugqwala kukagesi bamapayipi ensimbi okuthuthwa okugqitshiwe noma okungaphezulu komhlaba kwe-petroleum negesi yemvelo.Izinga lokushisa lomklamo walo elisebenzayo lingu -45℃ ~ 100℃.

Izisetshenziswa Zekhwalithi

Amandla okushisa: 2500V 50Hz iminithi elingu-1 akukho ukuphazamiseka noma i-arc;

Ukumelana ne-insulation: DC 1000V ukumelana ≥6M ω;

Ingcindezi yokuhlola i-Hydrostatic: izikhathi eziyi-1.5 zokucindezela kokuklama;

Ukucindezela kokuhlolwa okungangeni komoya: okulingana nokucindezela kokuklama;

Ukuhlolwa okungabhubhisi: ngokusho kwe-JB4730-94, wonke amalunga ezinqeni ahlolwa nge-radiographic eyi-100%, futhi wonke amanye ama-welds ane-bearing 100% wokuhlolwa kwezinhlayiyana kazibuthe;

I-Groove: sebenzisa i-API5L ejwayelekile.

Izimpahla zokufaka

1. Gwema ukushisela phakathi kwamamitha angu-50 kusukela ekufakweni kwamajoyinti okufakelwa;

2. Ngemva kokuxhuma i-insulation joint nepayipi, ungaliphakamisi ipayipi phakathi kwamamitha angu-5 ukusuka ekuhlanganyeleni;

3. Ukuhlolwa kwengcindezi yejoyinti lokufakelwa kanye nensimbi yepayipi.
