Monolithic Insulating Joint One Piece Insulating Joint A694 F70

Hoʻolauna Huahana

ʻO ka monolithic insulating joint he inoa maʻamau no ka hui e hiki ke pani i ka insulationflangea loaʻa iā ia ka hana hoʻopaʻa ʻana e koi ʻia e ka paipu kila i kanu ʻia a me ka hana insulation uila e koi ʻia e ka ʻenekinia pale corrosion.Aia i loko o ke kŘkohu mea hoʻohana he mau ʻāpana hoʻohui i loko a me waho, a me ka ʻaʻahu sila insulating i waenakonu o ka ʻāpana hoʻohui a me nā paipu pōkole kila i wili ʻia me ka ʻāpana hoʻohui.He mea nui ia no ka pale cathodic o ka pipeline i ka lawe ʻana i ka pipeline i mea e pale ai i ka corrosion electrochemical.ʻOi aku ka ʻoi aku o ka ʻoi aku ka ʻoi aku o ka ʻoi aku o ka insulation flange, hiki ke hoʻopaʻa i ka manawa kūlou nui, ka hana insulation kiʻekiʻe, ke ola lōʻihi, a hiki ke kanu ʻia i ka hoʻonohonoho.

Hoʻokumu ʻia ka hui hoʻohui monolithic i nā ʻāpana aʻe: paipu luna, paipu haʻahaʻa, lima lima, ʻāpana insulating, ʻāpana hoʻopaʻa ʻana, ka uhi ʻana.Aia nā ʻāpana insulating a me nā ʻāpana hoʻopaʻa ʻana i nā paipu luna a me lalo o nā ʻāpana hope o ka insulation joint butt, e hana ana i kahi ʻano hoʻopaʻa paʻa pālua me ka hana insulation.Hoʻohana ka lima i ka welding groove a i ʻole ke kuʻi pololei ʻana me ka conduit o luna.Hoʻopaʻa paʻa ʻia nā ʻāpana insulating a me nā paipu o luna a me lalo i loko e hana i kahi "paʻa i hoʻopaʻa ʻia", ʻaʻole ia he hopena insulating maikaʻi wale nō, akā hoʻomaikaʻi nui hoʻi i ka hiki ke lawe ʻia o ka hale insulating.

Nā mea waiwai

1. ʻO ka mea metala o ka hui insulation ke kila make i hoʻoheheʻe ʻia e ka umu uila a i ʻole ka mea hoʻololi oxygen, a ʻo ke kila i hoʻoheheʻe ʻia ma kahi mahana ma lalo o -20 ° C e hoʻomaʻemaʻe ʻia ma waho o ka umu.

2. Pono nā koi loea o ke kila e hoʻokō i nā koi hoʻolālā o ka ʻoihana hoʻolālā pipeline e pili ana.

3. ʻO ke kila i hoʻohana ʻia no ka hana ʻana i ka hui insulation e loaʻa i ka palapala hōʻoia maikaʻi, a ʻo ka mea hana o ka hui insulation e nānā a ʻae i ke kila e like me ka palapala hōʻoia.

4. Hoʻohana ʻia nā mea hoʻohana no nā mea hoʻoemi i ka NB/T 47008 a me NB/T 47009.

5. Pono e kohoʻia nā mea hoʻohana no nā mea hoʻopili e like me ke kaomi hoʻolālā, ke kaumaha a me ka nui.

Nā kahua noi

Hoʻopili ʻia kēia maʻamau i nā hui insulating monolithic me ke anawaena nominal ʻaʻole iʻoi aku ma mua o 600mm a me ke kaomi hoʻolālā ʻaʻole iʻoi aku ma mua o 16MPa a me ke anawaena nominal ʻaʻole iʻoi aku ma mua o 1400mm a me ke kaomi hoʻolālā ʻaʻole iʻoi aku ma mua o 12MPa, i kapa ʻia he insulating. nā hui, i ka ʻenekinia pale ʻino uila o nā paipu kila o ke kanu ʻia a i ʻole ka lawe ʻana o ka ʻaila a me ke kinoea maoli.ʻO ka pae wela hoʻolālā kūpono -45 ℃ ~ 100 ℃.

Pono Pono

Ka ikaika insulation: 2500V 50Hz 1 minuke ʻaʻohe haki a i ʻole arc;

Ke kū'ē kū'ē: DC 1000V kū'ē ≥6M ω;

Hydrostatic ho'āʻo kaomi: 1.5 manawa o ka hoʻolālā kaomi;

Pumi ho'āʻo ea: e like me ke kaomi hoʻolālā;

ʻO ka hoʻāʻo ʻole luku: e like me JB4730-94, ʻo 100% ka nānā ʻana i ka radiographic i nā ʻāpana āpau, a ʻo nā welds ʻē aʻe a pau he 100% ka nānā ʻana i nā ʻāpana magnetic;

Groove: hoʻohana i ka maʻamau API5L.

Nā lako hoʻokomo

1. E pale i ka wiliwili i loko o 50 mau mika o ka hoʻokomo ʻana i nā hui insulation;

2. Ma hope o ka hoʻohui ʻana i ka hui insulation me ka pipeline, mai hāpai i ka pipeline i loko o 5 mika o ka hui;

3. Ka ho'āʻo kaomi o ka hui insulation a me ka paipu mea kani.
