ʻO kā mākouNā paipu kila ERWua hoʻolālā kūikawā ʻia e hoʻokō i nā koi o nā ʻoihana like ʻole a me nā noi. Maipaipu kila kalapona i hoʻopaʻa ʻiai ka paipu API5L GR.B, hāʻawi mākou i kahi koho piha o nā huahana e mālama i kāu mau pono kikoʻī. Hana ʻia me ka pololei a me ka ʻike loea, kā mākouNā paipu MS ERWua kaulana lākou no ko lākou kūpaʻa a me ka ikaika, e kūpono ai lākou no nā noi mechanical a me ke kaomi. Inā he mau laina mahu, nā laina wai, nā laina kinoea, a i ʻole nā laina ea, hiki i kā mākou mau paipu ke lawelawe i nā pilikia o nā wahi koi me ka maʻalahi.

ʻO ka mea e hoʻokaʻawale ai i kā mākou mau paipu kila ERW ʻo ia ko lākou hiki ke hoʻopili ʻia. He kūpono loa lākou no nā noi hoʻopili ʻana, e ʻae ana i ka hui pū ʻana o nā ʻāpana paipu me ka ʻole o ka hoʻopili ʻana. Eia kekahi, kūpono hoʻi lākou no ka hana ʻana i nā hana e like me ke kāwili ʻana, ke kūlou ʻana, a me ka flanging, e wehe ana i nā ʻano hiki ke hana ʻia ma ke ʻano o ka hoʻolālā a me ka hana.
Hana ʻia me ka hoʻohana ʻana i ke ʻano hana kuʻi uila kūʻē (ERW), hōʻoia kā mākou mau paipu i kahi hana kūpaʻa a hilinaʻi hoʻi. Hōʻoia kēia ʻano hana kuʻi i nā pilina ikaika a kūlike ma o ka lōʻihi o ka paipu, e hāʻawi ana iā ʻoe i kahi huahana hilinaʻi e kū ana i nā kūlana ʻoihana kiʻekiʻe loa.
Hāʻawi mākou i nā koho like ʻole e hoʻokō i kāu mau koi kikoʻī.Nā paipu kila ERWloaʻa i nā nui like ʻole a me nā papa, me ka papa A a me ka papa B. Hiki iā ʻoe ke koho i ka huahana kūpono no kāu papahana, e hōʻoiaʻiʻo ana i ka hana kūpono a me ke ola lōʻihi.
No ka hoʻonui hou aku i ka maʻalahi a me ka maʻalahi, loaʻa kā mākou mau paipu i nā lōʻihi like ʻole a hiki ke hoʻopilikino ʻia i kāu mau kikoʻī i makemake ʻia. Inā makemake ʻoe i nā wēlau maʻamau, nā wēlau beveled, a i ʻole nā wēlau wili, loaʻa iā mākou ka hopena e kūpono i kāu mau pono kikoʻī.
Hoʻomaopopo mākou i ke koʻikoʻi o nā pilina paʻa a me ka hoʻohui ʻana maʻalahi i nā ʻōnaehana pipeline. ʻO ia ke kumu e hāʻawi aku ai mākou i nā koho hoʻopili like ʻole e hōʻoia i ka hui paʻa a me ka leaka ʻole o kā mākou mau paipu. Ua hoʻolālā ʻia kā mākou mau hoʻopili e hāʻawi i kahi sila paʻa, e hōʻoiaʻiʻo ana i ka hana lōʻihi a me ka maluhia o ka noʻonoʻo.
Me kā mākou mau paipu kila ERW, hiki iā ʻoe ke hilinaʻi e loaʻa ana iā ʻoe kahi huahana kiʻekiʻe loa i kūkulu ʻia e mau loa. Hoʻohui mākou i nā mea hana kiʻekiʻe, nā kaʻina hana holomua, a me nā hana hoʻomalu maikaʻi koʻikoʻi e hāʻawi i kahi huahana e ʻoi aku ma mua o nā mea i manaʻo ʻia.
I ka hopena, ʻo kā mākouNā paipu i hoʻopaʻa ʻia ʻo ERWʻo ia ke koho kūpono no nā ʻano hana like ʻole. Inā ʻoe e pono iā lākou no nā noi mechanical a me ke kaomi, nā hana kuʻihao, a i ʻole e lawe wale i nā wai a me nā kinoea, hāʻawi kā mākou mau paipu i ka hana kupaianaha a me ka hilinaʻi. E hilinaʻi i ko mākou akamai a koho i kā mākou mau paipu kila ERW no kāu papahana aʻe.
