I-Monolithic Insulating Joint One Piece Insulating Joint A694 F70

Intshayelelo yeMveliso

I-monolithic insulating joint ligama eliqhelekileyo lejoyinti elinokuthi lithathe indawo yokugqumaiflangekwaye inomsebenzi wokutywina ofunekayo kumbhobho wentsimbi ongcwatyiweyo kunye nokusebenza kokufakelwa kombane okufunwa yinjineli yokukhusela ukuthotywa kombane.Imodeli esetyenziswayo iquka iperi yangaphakathi nangaphandle yokudibanisa yangaphakathi, kunye nengubo yokuvala i-insulating seal embindini wecandelo lokudibanisa kunye neeperi zentsimbi ezimfutshane zemibhobho ezidityanisiweyo kunye nenxalenye yokudibanisa ngokulandelanayo.Iyinxalenye ebalulekileyo yokukhusela i-cathodic yepayipi yokuthutha imibhobho ukwenzela ukuthintela ukubola kwe-electrochemical.Inokuqina okuphezulu kune-insulation flange, inokuthwala umzuzu omkhulu wokugoba, ukusebenza okuphezulu kwe-insulation, ubomi obude, kwaye inokungcwatywa kufakelo.

I-monolithic insulating joint yenziwe ngala malungu alandelayo: umbhobho ongaphezulu, umbhobho osezantsi, umkhono, iindawo zokugquma, iindawo zokutywina, ukugquma kwe-insulating.Kukho iindawo zokugquma kunye neendawo zokutywina kwimibhobho ephezulu kunye nesezantsi ye-insulation joint butt end parts, ezenza isakhiwo sokutywina kabini kunye nokusebenza kwe-insulation.Umkhono wamkela i-groove welding okanye i-welding ngqo kunye ne-conduit ephezulu.Iindawo ezikhuselayo kunye nemibhobho ephezulu kunye nezantsi zitywinwe ngokuqinileyo ngaphakathi ukuze zenze "isitya esitywiniweyo", esingenalo kuphela umphumo omuhle wokukhusela, kodwa siphucula kakhulu amandla okuthwala isakhiwo se-insulating.

Izinto eziphathekayo

1.Izinto zetsimbi ze-insulation joint ziya kuba yintsimbi ebuleweyo encibilikiswe sisithando sombane okanye i-oxygen converter, kunye nentsimbi enyibilikisiweyo kwiqondo lokushisa elingaphantsi kwe -20 ° C iya kucocwa ngaphandle kwesithando somlilo.

I-2.Iimfuno zobugcisa zetsimbi kufuneka zihlangabezane neemfuno zoyilo lwesebe loyilo lobunjineli bombhobho olufanelekileyo.

3.Intsimbi esetyenziselwa ukudibanisa ukudibanisa iya kuba nesatifikethi somgangatho, kwaye umenzi we-insulation joint uya kujonga kwaye amkele intsimbi ngokwesatifikethi somgangatho.

4.I-Forgings esetyenziselwa izinto zoxinzelelo iya kuhambelana ne-NB/T 47008 kunye ne-NB/T 47009.

I-5.I-Forgings esetyenziselwa amacandelo oxinzelelo kufuneka ikhethwe ngokoxinzelelo loyilo, ubunzima kunye nobukhulu.

Iinkalo zesicelo

Lo mgangatho usebenza kwi-monolithic insulating joints kunye nedayamitha yegama elingekho ngaphezu kwe-600mm kunye noxinzelelo loyilo olungekho ngaphezu kwe-16MPa kunye nedayamitha yegama elingekho ngaphezu kwe-1400mm kunye noxinzelelo loyilo olungekho ngaphezu kwe-12MPa, ekubhekiselwa kuyo njenge-insulating. amalunga, kubunjineli bokukhusela i-corrosion yombane wemibhobho yentsimbi yokungcwaba okanye ngaphezulu kokuthuthwa komhlaba kwepetroleum kunye negesi yendalo.Uluhlu olusebenzayo loyilo lobushushu luyi-45℃ ~ 100℃.

Izixhobo zoMgangatho

Uxinzelelo lovavanyo lwe-Hydrostatic: amaxesha angama-1.5 oxinzelelo loyilo;

Uxinzelelo lovavanyo olungangeni moya: lilingana noxinzelelo loyilo;

Uvavanyo olungonakalisi: ngokwe-JB4730-94, onke amalunga e-butt yi-100% yokuhlolwa kwe-radiographic, kunye nazo zonke ezinye ii-welds zokuthwala ziyi-100% yokuhlolwa kwe-particle magnetic;

IGroove: yamkela umgangatho we-API5L.

Izixhobo zoFakelo

1. Gwema i-welding ngaphakathi kweemitha ezingama-50 zofakelo lwe-insulation joints;

2. Emva kokudibanisa i-insulation joint kunye nombhobho, musa ukuphakamisa umbhobho ngaphakathi kweemitha ezi-5 zokudibanisa;

3. Uvavanyo loxinzelelo lwe-insulation joint kunye nesixhobo sombhobho.
