Umgangatho malunga ne-Insulated Flange.

I-insulated flangesisixhobo sokudibanisa esisetyenziswa kwiinkqubo zemibhobho, enophawu lokuhlukanisa okwangoku okanye ubushushu.Oku kulandelayo kukwazisa ngokubanzi kwiiflange ezigqunyiweyo:

Ubungakanani

Ubukhulu obuqhelekileyo bubandakanya iinkcukacha ezahlukeneyo ezifana ne-DN15 ukuya kwi-DN1200, kunye nobukhulu obuthile kufuneka bukhethwe ngokusekelwe kusetyenziso kunye nemigangatho.

Uxinzelelo

Ukusebenza kokumelana noxinzelelo lweeflange ezifakwe kwi-insulated kuxhomekeke kwizinto zabo zokuvelisa kunye nemigangatho yoyilo.Ngokuqhelekileyo, inokuhlangabezana neemfuno ezithile zoxinzelelo lomsebenzi, njengemigangatho eqhelekileyo efana ne-PN10 kunye ne-PN16.

Ukuhlelwa

Iiflange ezigqunyiweyo zinokuhlelwa ngokweendidi ezahlukeneyo ngokwesakhiwo kunye nomsebenzi wazo, njengale:

1. I-Flange eboshiweyo: idityaniswe ngamabholiti, alungele ukudityaniswa kwemibhobho ngokubanzi.

2. Welding flange: Idityaniswe nge-welding, esetyenziswa ngokuqhelekileyo kwiindawo ezinobushushu obuphezulu kunye noxinzelelo oluphezulu.

3. Irabha flange: Ukusebenzisa irabha okanye ezinye izinto zokugquma, ezifanelekileyo kwizihlandlo ezifuna ukutshatyalaliswa kombane okanye i-thermal.

Iimbonakalo

1. Ukusebenza kwe-Insulation: Into ephambili yikhono lokuhlukanisa ngokufanelekileyo ngoku okanye ukushisa, ukukhusela ukuphazamiseka kunye nomonakalo.

2. Ukumelana nokutyiwa: Yenziwe ngezinto ezikwaziyo ukumelana nomhlwa, zilungele indawo ezonakalisayo ezifana nobunjineli bemichiza.

3. Ukufakela lula: Ngokuqhelekileyo ibhoti okanye i-welded ukuze kube lula ukufakwa.

Izinto eziluncedo nezingeloncedo

Inzuzo

Ibonelela ngokuhlukaniswa kombane kunye ne-thermal, efanelekileyo kwiindawo ezikhethekileyo;Ukuchasana kakuhle kokutya;Kulula ukuyifaka.

Ukusilela

Iindleko ziphezulu ngokwentelekiso;Kwiindawo ezithile ezinoxinzelelo oluphezulu kunye nobushushu obuphezulu, uyilo olunzima ngakumbi lunokufuneka.

Umda wosetyenziso

Iiflange ezigqunyiweyo zisetyenziswa ngokubanzi kumashishini ahlukeneyo, kubandakanywa kodwa kungaphelelanga apho:

1. Ishishini lemichiza: Iisistim zemibhobho ezifuna ukugqunywa kwezixhobo zemichiza.

2. Ushishino lwamandla: Kwiimeko apho kufuneka ukwahlukana kombane, njengokudityaniswa kwentambo.

3. Ishishini leMetallurgical: Ukudityaniswa kwemibhobho kwindawo yobushushu obuphezulu kunye noxinzelelo oluphezulu.

4. Amanye amabala oshishino: amaxesha aneemfuno ezizodwa zokuqhuba kwangoku okanye ubushushu.

Xa ukhetha i-insulation flanges, kuyimfuneko ukumisela uhlobo olufanelekileyo kunye neenkcukacha ezisekelwe kwimeko ethile yokusetyenziswa, iimpawu eziphakathi kunye neemeko zokusebenza.

Uvavanyo olungqongqo

I-1.Ii-insulating joints kunye ne-insulating flanges eziye zaphumelela uvavanyo lwamandla kufuneka zivavanywe ukuqina enye enye kwiqondo lokushisa elingekho ngaphantsi kwe-5 ° C.Iimfuno zovavanyo kufuneka zingqinelane nemimiselo ye-GB 150.4.

I-2.Uxinzelelo lwe-tightness test kufuneka luzinzile kwi-30 imizuzu kwi-0.6MPa yoxinzelelo kunye nemizuzu ye-60 kwixinzelelo loyilo.Indawo yokuvavanya ngumoya okanye igesi engasebenziyo.Akukho kuvuza kuthathwa njengefanelekileyo.
