Ikaika o ka Paipu Welded Pālua i nā Noi ʻOihana

Ka ikaika o ka paipu wili pālua i nā noi ʻoihana Kiʻi i hōʻike ʻia

Wehewehe Pōkole:

I ke ao o nā paipu ʻoihana, hiki i ke koho ʻana i nā mea a me nā ʻano hana kūkulu ke loaʻa ka hopena koʻikoʻi i ka hana holoʻokoʻa a me ke ola lōʻihi o ka ʻōnaehana. ʻO kekahi ʻano hana i kaulana no kona ikaika a me ke kūpaʻa, ʻo ia ka hoʻohana ʻana i ka paipu pālua. Ua hoʻolālā ʻia kēia mau paipu e kū i nā kaomi kiʻekiʻe, nā mahana koʻikoʻi a me nā kūlana kaiapuni koʻikoʻi, e kūpono ai lākou no nā ʻano hana ʻoihana like ʻole.

Nā paipu i hoʻopaʻa ʻia pāluaua kūkulu ʻia me ʻelua mau wili kūʻokoʻa e hana i kahi pilina ikaika a hilinaʻi hoʻi ma waena o nā ʻāpana paipu. Hōʻoia kēia kaʻina hana wili pālua e hiki i ka paipu ke kū i nā pilikia a me nā ʻūlū e hiki ke hālāwai i ka wā o ka hana, e lilo ia i koho hilinaʻi no nā noi koʻikoʻi kahi i ʻole ai ka hāʻule ʻana he koho.

ʻO kekahi o nā pono nui o nā paipu i hoʻopili ʻia i ka pālua ʻo ia ko lākou hiki ke lawelawe i nā wahi kaomi kiʻekiʻe. Hoʻokumu ke kaʻina hana hoʻopili pālua i kahi pilina paʻa a maʻalahi hoʻi ma waena o nā ʻāpana paipu, e hōʻoiaʻiʻo ana e hiki iā lākou ke kū i nā kaomi kūloko me ka ʻole o ka pilikia o ka leaka a i ʻole ka hāʻule ʻana. ʻO kēia ka mea kūpono iā lākou no nā noi e like me nā paipu aila a me ke kinoea, kahi e koʻikoʻi ai ka pono o ka ʻōnaehana paipu i ka palekana a me ka pono o ka hana.

Ma waho aʻe o kona ikaika, hiki i ka paipu wili pālua ke kū i nā mahana koʻikoʻi, e kūpono ai no nā ʻano hana ʻoihana like ʻole. Inā paha e lawe ana i nā wai wela a i ʻole nā kinoea, a i ʻole e hana ana i nā wahi me nā mahana e loli mau ana, mālama ka paipu wili pālua i kona kūpaʻa kūkulu a me ka hana, e hōʻoiaʻiʻo ana i ka hana hilinaʻi ma lalo o nā kūlana paʻakikī loa.

Eia kekahi, ʻo ke kūpaʻa o ka paipu wili pālua e lilo ia i koho kūpono no nā noi ʻoihana. ʻO ko lākou hiki ke kū i ke komo ʻana, ka pala a me nā ʻano ʻē aʻe o ka hōʻino ʻana, ʻo ia hoʻi he liʻiliʻi ka mālama a me ka hoʻololi ʻana, e hōʻemi ana i nā kumukūʻai hana holoʻokoʻa a me ka manawa downtime.

Ma keʻano holoʻokoʻa, hāʻawi ka hoʻohana ʻana i ka paipu wili pālua i nā pono like ʻole no nā noi ʻoihana, me ka ikaika, ka lōʻihi a me ka hilinaʻi. ʻO ko lākou hiki ke lawelawe i nā kaomi kiʻekiʻe, nā mahana koʻikoʻi a me nā kūlana kaiapuni koʻikoʻi e kūpono ai lākou no nā ʻano ʻoihana like ʻole mai ka ʻaila a me ke kinoea a hiki i ka hana kemika. Me kāna hana i hōʻoia ʻia a me ka moʻolelo ola lawelawe, he waiwai nui ka paipu wili pālua i kekahi ʻōnaehana paipu ʻoihana.
