ʻO ka ʻokoʻa ma waena o ka hui kuʻihao paʻa, ka hui kuʻi hoʻololi ʻana a me ka hui kuʻihao prefabricated i ka wiliwili paipu

ʻO ka hoʻololi ʻana e pili ana i ka hoʻopaʻa ʻana i ka hoʻoheheʻe ʻana i ka pipeline. ʻO ka hoʻopaʻa paʻa ʻana, ʻaʻole hiki ke neʻe ka hui kuʻi ma hope o ka hui ʻana o ka hui paipu, a hana ʻia ke kuʻi ʻana e like me ka hoʻololi ʻana o ke kūlana kuʻi (horizontal, vertical, upward, a me nā hoʻololi waena waena) i ke kaʻina hana kuʻi.

ʻO ka hoʻololi ʻana i ke awa kuʻi ʻana ʻo ia ka hoʻohuli ʻana i ke awa kuʻihao i ka wā o ke kaʻina hana i hiki i ka welder ke hana i ke kuʻi ʻana i kahi kūlana kūpono (kekahi o ke aniani, kū pololei, luna a i lalo).

Loaʻa i nā lako wili Xinfa nā hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe a me ke kumu kūʻai haʻahaʻa. No nā kikoʻī, e kipa:Welding & Oki Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)

ʻO ka ʻoiaʻiʻo, ma ka ʻōlelo wale ʻana, ʻo ka hui kuʻi paʻa ka weld seam welded ma luna o ka pūnaewele, e pili ana i ka pipeline prefabricated.

ʻO ka hui kuʻihao paʻa, ʻo ia ka mea ʻaʻole e neʻe ka paipu, a hana ka welder i ka wiliwili a puni, ʻoi aku ka nui o ke ʻano o ka welding, ʻaʻole maʻalahi ke ʻano o ka welding, kiʻekiʻe nā koi ʻenehana o ka welder, a ʻoi aku ka maikaʻi o nā hemahema. hiki mai. ʻO ka mea maʻamau, aia ke kūkulu ʻia ma ka hale paipu;

ʻO ke awa hoʻololi he paipu hiki ke hoʻololi. ʻO ke kūlana kuʻekuʻe he kuʻekuʻe palahalaha a i ʻole ke kuʻi kuʻi ʻana. He maʻalahi ka hana kuʻi ʻana a he liʻiliʻi nā hemahema. Ua kūkulu ʻia ma ka honua a i ʻole ma ka papahele.

I ka wā o ka nānā ʻana i ka welding, i mea e pale aku ai i nā awa wili a pau mai ke koho ʻole ʻia no ka nānā ʻana, ua kiʻekiʻe ka nui o ka pass, a pono e nānā pono ʻia kekahi ʻāpana o nā awa paʻa e hōʻoia i ka maikaʻi wili o ka pipeline holoʻokoʻa. ʻO ka "Pressure Pipeline Safety Technology Supervision Regulations–Industrial Pipeline" e ʻōlelo ʻia ʻaʻole e emi iho ka ratio ʻike o nā hui kuʻihao paʻa ma mua o 40%.

Ma keʻano laulā, hoʻohana mākou i ke awa paʻa e like me ke awa hana. ʻO ke awa ikaika ka hui kuʻihao prefabricated o ka paipu, a hiki ke hoʻoneʻe ʻia ka ʻāpana paipu i ka wā i hana mua ʻia ai ka paipu ma waho o ka pūnaewele. ʻO ke awa paʻa he awa welded i hoʻokomo ʻia i ka pūnaewele kahi hiki ʻole ke hoʻoneʻe a hoʻololi ʻia ka paipu.

I ka lōʻihi o ka pipeline pipeline kikoʻī, ua kapa ʻia ʻo "collision dead end", a koi ʻia ʻo "100% radiographic inspection e hoʻokō ʻia". He paʻakikī ke kihi kuʻi hope make, a ʻaʻole maʻalahi ka hōʻoia ʻana i ka maikaʻi kuʻi.

Pili nā welds paʻa i nā welds rotating.

ʻO ka hui ʻana o ka weld ʻo ia ka mea hiki i ka welder ke hoʻololi manuahi i ka hui kuʻi ʻana e like me ke kihi ʻoluʻolu loa o ka hana kuʻi ʻana i ka wā o ke kaʻina hana kuʻihao prefabricated o ka pipeline, a ua paʻa ka maikaʻi o ka welding, no laila e like nā welders i kēia ʻano hui weld.

Eia naʻe, ma muli o nā koi o nā kūlana pūnaewele a i ʻole nā ​​kūlana o ka mea hana ponoʻī, hiki ke hoʻopaʻa ʻia ka hui kuʻi ʻana o kekahi mau mea hana, ʻo ia ka mea i kapa ʻia ʻo ka hui kuʻi paʻa. Ke hoʻokomo ʻia ka hui kuʻihao paʻa a hoʻopaʻa ʻia, hoʻokahi wale nō ʻaoʻao kuʻihao hui. He paʻakikī kēia ʻano hui kuʻi ʻana, a kiʻekiʻe ka hapa o ka hoʻāʻo ʻole luku.

I kekahi mau kikoʻī kūkulu pipeline, ʻike maopopo ʻia ka māhele o ka ʻike weld paʻa. No ka mea he ʻokoʻa nā kihi o nā welds paʻa, e loli ka wili lima lima, a e hoʻopili ʻia ka maikaʻi o nā welds i kekahi ʻano. No ka laʻana, ʻo nā welds paʻa o nā paipu kila e koi i nā welders e hana i nā kūlana āpau, e koi ana i nā koi kiʻekiʻe no nā welders. ʻOiaʻiʻo, kiʻekiʻe ka ʻenehana a kiʻekiʻe ka pae ʻenehana. ʻAʻole pili ka welder maikaʻi.

I ka hoʻokele kūkulu hale, pono e hoʻemi ʻia ka helu o nā puka paʻa e like me ka hiki. Ma kekahiʻaoʻao, hiki ke hoʻomaluʻia ka maikaʻi o ka welding, a ma ka manawa like, hiki ke hoʻemiʻia ka helu o nā puka nānā e ho'ēmi i nā kumukūʻai.
