ʻO ka ʻokoʻa ma waena o nā hui kuʻihao paʻa, nā hui kuʻi wiliwili ʻana a me nā hui kuʻihao prefabricated i ka wili pipeline.

ʻAʻohe mea i kahi o ka hui kuʻihao, he hōʻiliʻili maoli ia o ka ʻike kuʻi. No ka poʻe hoʻomaka, ʻo nā kūlana maʻalahi nā hoʻomaʻamaʻa maʻamau, e hoʻomaka me nā hoʻololi ʻana a laila neʻe i nā hoʻomaʻamaʻa kūlana paʻa.

ʻO ka mea hoʻohālikelike i ka hoʻopaʻa ʻana i ka hoʻoheheʻe ʻana i ka pipeline he rotational welding. ʻO ka hoʻopaʻa paʻa ʻana, ʻaʻole hiki ke neʻe ka hui kuʻi ma hope o ka hui ʻana o ka pipeline. I ka wā o ke kaʻina hana kuʻi, hoʻololi ke kūlana kuʻi (horizontally, vertically, upwardly and downwardly).

ʻO ka hoʻololi ʻana i ke awa kuʻi ʻana, ʻo ia ka hoʻololi ʻana i ke awa kuʻihao i ka wā o ke kaʻina hana hoʻoheheʻe 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 paha).

ʻO kaʻoiaʻiʻo, e kau maʻalahi, ua hoʻopaʻa ʻia nā hui wili paʻa i welded ma ka pūnaewele, i hoʻohālikelike ʻia me nā paipu prefabricated.

ʻO ka hui kuʻi paʻa paʻa ʻo ia ka mea ʻaʻole e neʻe ka paipu a hana ka welder i ka wiliwili a puni. ʻOi loa i ka wā e wili ai i luna, paʻakikī ke ʻano o ka welding, pono nā koi ʻenehana kiʻekiʻe no ka welder, a hiki i nā hemahema. Ua hana mau ia ma ka hale paipu;

ʻO ke awa wili e hiki ai i ka paipu ke hoʻololi, a ʻo ke kūlana kuʻi ʻana ʻo ia ke kuʻi paʻa paʻa 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 ka papahele.

I ka wā o ka nānā ʻana i ka welding, i mea e pale ai i ke koho ʻia ʻana o nā awa wili a pau no ka nānā ʻana a loaʻa i kahi helu pass kiʻekiʻe, pono ia e nānā maʻamau i kekahi māhele o nā awa paʻa e hōʻoia i ka maikaʻi o ka welding o ka pipeline holoʻokoʻa. ʻO ka "Pressure Pipeline Safety Technical Supervision Regulations-Industrial Pipelines" e kuhikuhi ana i ka ratio ʻike o nā hui kuʻi paʻa ʻaʻole i emi iho ma mua o 40%.

Ma lalo o nā kūlana maʻamau, hoʻohana mākou i ke awa paʻa e like me ke awa hoʻoneʻe. ʻO ke awa hiki ke hoʻoneʻe ʻia he hui welded prefabricated o ka pipeline. Hiki ke hoʻoneʻe ʻia ka ʻāpana paipu i ka wā i hana mua ʻia ai ka pipeline ma waho o ka pūnaewele. ʻO ke awa paʻa he awa welded i hoʻokomo ʻia i ke kahua, a ʻaʻole hiki i ka paipu ke neʻe a ʻōwili paha i kēia manawa.

Ua kapa ʻia nā kikoʻī pipeline no nā pipeline lōʻihi "nā wahi make" a koi ʻia "100% radiographic inspection." He paʻakikī ke kihi kuʻi kuʻi make a ʻaʻole maʻalahi ka maikaʻi kuʻi ʻana.

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 ke awa kuʻihao paʻa e pili ana i ke awa kuʻi wili.

ʻO ka hui wiliwili ʻana i ka wā o ka pipeline prefabrication welding kaʻina, hiki ke hoʻololi ʻia ka hui kuʻi ma ka makemake e like me ka ʻoluʻolu loa o ka hana kuʻi. Paʻa ka maikaʻi o ka wili, no laila makemake nā welders i kēia ʻano hui kuʻi.

Eia naʻe, hiki ke hoʻopaʻa ʻia kekahi mau hui kuʻihao mea hana ma muli o nā kūlana kahua a i ʻole nā ​​palena o ka mea hana ponoʻī. ʻO kēia ka mea i kapa ʻia ka hui kuʻi paʻa. Ke hoʻokomo ʻia ka hui kuʻihao paʻa a hoʻopaʻa ʻia, hoʻokahi wale nō ʻaoʻao kuʻihao hui. ʻO kēia ʻano hui kuʻi he paʻakikī ke weld a koi i kahi ʻāpana kiʻekiʻe o ka hoʻāʻo ʻole luku.

I kekahi mau kikoʻī kūkulu ʻana i ka pipeline, ʻike maopopo ʻia ka māhele o ka nānā ʻana i ka hui weld paʻa. No ka mea ʻokoʻa nā kihi o nā hui kuʻi paʻa, e loli ka wili lima, a ʻo ka maikaʻi o nā hui kuʻi e loaʻa kekahi hopena. No ka laʻana, ʻo nā hui kuʻihao paʻa o nā paipu kila e koi i nā welders e hana i nā kūlana āpau, kahi e koi nui ai i nā welders. ʻOiaʻiʻo, loaʻa iā lākou nā ʻenehana kiʻekiʻe a me nā pae ʻenehana. ʻAʻole mālama 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 iā ia ke hoʻomalu i ka maikaʻi o ka welding, a ma ka manawa like, hiki iā ia ke hoʻemi i ka helu o nāʻehaʻike a hoʻemi i nā kumukūʻai.
