Monolithic Insulating Joint One Piece Insulating Joint A694 F70

Product Sumo

Iyo monolithic insulating joint izita rakajairika rejoint iro rinogona kutsiva insulationflangeuye ine zvese zvekuisa chisimbiso zvinodikanwa nepombi yesimbi yakavigwa uye mashandiro emagetsi ekudzivirira anodiwa nemagetsi ekudzivirira ngura.Iyo utility modhi inosanganisira maviri emukati nekunze ekubatanidza zvikamu, uye insulating chisimbiso jasi pakati pekubatanidza chikamu uye peya yesimbi mapfupi mapaipi akasungwa nechikamu chekubatanidza zvakateerana.Icho chinhu chakakosha chekuchengetedza cathodic yepombi mukufambisa kwepombi kuitira kudzivirira electrochemical corrosion.Iyo ine kuomarara kwepamusoro pane insulation flange, inogona kutakura yakakura yekukotama nguva, yakakwirira insulation kuita, hupenyu hurefu, uye inogona kuvigwa mukuiswa.

Iyo monolithic insulating joint inoumbwa nezvikamu zvinotevera: pombi yepamusoro, pombi yepasi, sleeve, insulating parts, kuisa chisimbiso, insulating coating.Kune zvikamu zvinodzivirira uye zvikamu zvekuisa chisimbiso mumapombi epamusoro uye ezasi eiyo insulation joint butt end parts, achigadzira kaviri yekuisa chisimbiso chimiro neinsulation performance.Sleeve inotora groove welding kana welding yakananga nemukoto wepamusoro.Zvikamu zvinodzivirira uye mapaipi epamusoro uye epasi zvakavharwa zvakasimba mukati kuti zvigadzire "chigadziko chakavharidzirwa", icho chisingaiti chete chakanaka chekudzivirira, asiwo chinovandudza zvikuru kukwanisa kwekutakura kwechimiro chekudzivirira.

Zvishandiso

1.Simbi yesimbi yejojo ​​yekudzivirira ichava simbi yakaurayiwa yakanyungudutswa nechoto chemagetsi kana kushandura oksijeni, uye simbi yakanyungudutswa pakupisa kwakadzika kudarika -20 ° C ichanatswa kunze kwechoto.

2.Izvo zvehunyanzvi zvinodiwa zvesimbi zvinofanirwa kusangana nezvinodiwa zvekugadzira zveiyo yakakodzera pipeline engineering design department.

3.Simbi inoshandiswa pakugadzira majoini ekugadzira ichave iine chitupa chemhando, uye mugadziri wejoint insulation achatarisa uye agamuchire simbi zvinoenderana nemhando yechitupa.

4. Forgings inoshandiswa kumanikidzira zvinhu inofanira kuenderana neNB/T 47008 uye NB/T 47009.

5.Forgings inoshandiswa pakugadzirisa zvikamu zvinofanirwa kusarudzwa maererano nekugadzirisa kwekugadzirisa, uremu uye ukuru.

Minda yekushandiswa

Iyi chiyero inoshanda kune monolithic insulating majoini ane dhayamita yezita isingapfuure 600mm uye dhizaini yekumanikidza isingapfuuri 16MPa uye dhayamita yezita isingapfuuri 1400mm uye dhizaini yekumanikidza isingapfuure 12MPa, inonzi insulating. majoini, mumagetsi ekudzivirira corrosion einjiniya emapaipi esimbi ekuvigwa kana pamusoro pevhu kutakurwa kwepetroleum uye gasi rechisikigo.Yayo inoshanda dhizaini tembiricha yemhando ndeye -45 ℃ ~ 100 ℃.
