ʻO nā paipu SSAW maikaʻi no nā noi kinoea kūlohelohe ma lalo o ka honua

ʻO ka wehewehe pōkole:

Ke hoʻolauna nei i ka paipu kila A252 Grade 2 kiʻekiʻe no nā paipu kinoea lalo


Huahana Huahana

Huahana Huahana

I loko o ka honua e ulu nei o ka ikehu, ʻo ka pono o nā mea hilinaʻi a paʻa ka mea nui. Haʻaheo mākou i ka hoʻolauna ʻana i kā mākou paipu kila A252 Grade 2 kiʻekiʻe, i hoʻolālā ʻia no nā noi pipeline kinoea lalo. Ma ke ʻano he alakaʻi paipu SSAW (Spiral Submerged Arc Welded), maopopo mākou he koʻikoʻi ka maikaʻi a me ka pololei o nā mea i hoʻohana ʻia no ka lawe ʻana i ke kinoea.

Kūlike ʻole a me ka pololei

ʻO kā mākouA252 Papa 2 paipu kilas ua hana ʻia i nā kūlana ʻoihana koʻikoʻi, e hōʻoia ana ʻaʻole ʻokoʻa ke anawaena o waho ma mua o ± 1% mai ke anawaena o waho i koho ʻia. He mea koʻikoʻi kēia pae o ka pololei i ka mālama ʻana i ka pono a me ka palekana o nā paipu kinoea kūlohelohe ma lalo o ka honua. Me kā mākou mau paipu, hiki iā ʻoe ke hilinaʻi e hoʻopili pono lākou i kāu ʻōnaehana i kēia manawa, e hōʻemi ana i ka hopena o ka leaks a hōʻoia i ka hana maikaʻi loa.

Nānā huahana

ʻAʻole ʻoi aku ka nui o ka phosphorus ma mua o 0.050% o ke kila.

ʻAe ʻia nā ʻano like ʻole i nā kaumaha a me nā ana

Pono e kaupaona ʻia kēlā me kēia lōʻihi o ka paipu paipu a ʻaʻole e ʻokoʻa kona kaumaha ma mua o 15% a i ʻole 5% ma lalo o kona kaumaha kumu, i helu ʻia me kona lōʻihi a me kona kaumaha no kēlā me kēia lōʻihi.
ʻAʻole e ʻokoʻa ke anawaena o waho ma mua o ±1% mai ka anawaena waho i koho ʻia
ʻAʻole ʻoi aku ka mānoanoa o ka pā ma kēlā me kēia wahi ma mua o 12.5% ​​ma lalo o ka mānoanoa pā i kuhikuhi ʻia

Ka lōʻihi

Nā lōʻihi like ʻole: 16 a 25ft(4.88 a 7.62m)
ʻElua mau lōʻihi like ʻole: ma luna o 25ft a 35ft(7.62 a 10.67m)
Nā lōʻihi like ʻole: ʻae ʻia ka hoʻololi ʻana ±1in

Hoʻopau

E hoʻolako ʻia nā puʻu paipu me nā wēlau maʻemaʻe, a e wehe ʻia nā ʻōpala ma nā wēlau
Ke pau ka hopena o ka paipu i ʻōlelo ʻia he bevel, ʻo ka huina o 30 a 35 degere

Hoailona huahana

E hōʻailona ʻia kēlā me kēia lōʻihi o ka paipu paipu e ka stenciling, stamping, a i ʻole ka ʻōwili ʻia e hōʻike: ka inoa a i ʻole ka inoa o ka mea hana, ka helu wela, ke kaʻina hana, ke ʻano o ka hili helical, ke anawaena o waho, ka mānoanoa o ka paia, ka lōʻihi, a me ke kaumaha o kēlā me kēia ʻāpana lōʻihi, ka ʻōlelo kikoʻī a me ka papa.

Paipu kila ke anawaena nui

 

ʻO ke kūkulu ʻia ʻana no ka lōʻihi loa

Hana ʻia kā mākou paipu A252 Class 2 mai ke kila kiʻekiʻe e hiki ke kū i nā kūlana koʻikoʻi i ʻike pinepine ʻia i nā kaiapuni lalo. ʻO ke kaʻina hana SSAW e hoʻonui i ka ikaika a me ka lōʻihi o ka paipu, i mea kūpono no nā noi kiʻekiʻe. Inā ʻoe e kau nei i kahi paipu kinoea kūlohelohe hou a i ʻole e hoʻololi i kahi paipu i loaʻa, hāʻawi kā mākou paipu kila iā ʻoe i ka hilinaʻi āu e pono ai e mālama pono i kāu mau hana.

Nā noi like ʻole

ʻAʻole kūpono kā mākou A252 Grade 2 Steel Pipes no nā pipeline gas ma lalo o ka honua, akā hiki ke hoʻohana ʻia a hiki ke hoʻohana ʻia i nā ʻano hana ʻē aʻe i ka ʻoihana ikehu. Mai ka lawe ʻana i ka wai a hiki i ke kākoʻo ʻana, hiki ke hoʻohana ʻia kēia mau paipu i nā ʻano papahana like ʻole a he mea waiwai nui ia i kāu waihona. Ma ke ʻano he mea kūʻai paʻa SSAW Pipe hilinaʻi, hōʻoia mākou e hoʻokō kā mākou huahana i nā pono like ʻole o kā mākou mea kūʻai aku ma nā ʻano ʻoihana like ʻole.

ʻO nā paipu hollow-section

 

HANAIA I KA HOIKE ANA

I kēia ao, ʻoi aku ka nui o ka hoʻomau ma mua o ka wā. ʻO kā mākou mau kaʻina hana e hana mua i nā hana pili i ke kaiapuni, e hōʻoia ana i kā mākou A252 Grade 2 Steel Pipe i hana ʻia me ka liʻiliʻi o ka hopena i ke kaiapuni. Ma ke koho ʻana i kā mākou huahana, ʻaʻole ʻoe e hoʻopukapuka wale i ka maikaʻi, akā ke hāʻawi pū nei ʻoe i kahi wā e hiki mai ana no ka ʻoihana ikehu.

ʻO ka lawelawe mea kūʻai aku maikaʻi loa

Ma kā mākou hui, ke manaʻoʻiʻo nei mākou he mea nui ka lawelawe mea kūʻai aku e like me ka maikaʻi o ka huahana. Hoʻolaʻa kā mākou hui ʻike i ka hāʻawi ʻana iā ʻoe i ke kākoʻo āu e pono ai, mai ke koho ʻana i ka paipu kūpono no kāu papahana a hiki i ka hōʻoia ʻana i ka hāʻawi ʻana i ka manawa. Hoʻomaopopo mākou he ʻokoʻa kēlā me kēia papahana, a eia mākou e kōkua iā ʻoe e hoʻomaopopo i kāu mau koho a hoʻoholo i kahi hoʻoholo.

I ka hopena

I ka hiki ʻana mai i nā pipeline kinoea kūlohelohe ma lalo o ka honua, ʻo ke koho ʻana i nā mea kūpono he mea koʻikoʻi e hōʻoia i ka palekana, ka pono, a me ka lōʻihi. Me kona mau ana kūpono a me ka hana ʻino, ʻo kā mākou paipu kila A252 Grade 2 ka hopena maikaʻi loa no kāu mau mea e pono ai ka lawe kinoea maoli. Ma ke ʻano he mea hoʻolaha paipu SSAW kaulana, ua kūpaʻa mākou e hāʻawi iā ʻoe i nā huahana kiʻekiʻe loa a me ka lawelawe kūikawā. E hilinaʻi iā mākou i hoa pili i ke kūkulu ʻana i kahi ʻoihana ikehu hilinaʻi a hoʻomau. E kelepona mai iā mākou i kēia lā e aʻo hou e pili ana i kā mākou paipu kila A252 Grade 2 a pehea e hiki ai iā mākou ke kākoʻo i kāu papahana aʻe!
