I ka wā e hiki mai anake kūkulu ʻana i nā paipu, ʻo ka hōʻoia ʻana i ko lākou kūpaʻa a me ke kūpaʻa ʻana i ka popopo he mea nui loa ia.Nā paipu kila kalapona LSAW, i ʻike ʻia hoʻi ʻo Longitudinal Submerged ArcNā paipu kuʻihao, he koho kaulana ia ma muli o ko lākou ikaika kiʻekiʻe a me ka hilinaʻi. No ka hoʻoikaika hou aku i ko lākou kūpaʻa i ka pala, hiki ke uhi ʻia kēia mau paipu me kahi polyethylene anti-corrosion ʻekolu papa i ʻike ʻia ʻo 3PE. Ma kēia blog, e ʻimi mākou i nā pono o ka hoʻohana ʻanaNā paipu kila kalapona LSAW i uhi ʻia me 3PEa no ke aha lākou he koho maikaʻi loa no nā ʻoihana like ʻole.
ʻO ka uhi anti-corrosion 3PE kahi hopena hilinaʻi e pale ana i nā paipu kila kalapona LSAW mai ka pala a hoʻolōʻihi i ko lākou ola. ʻO ka ʻano 3PE he ʻekolu papa, e hoʻomaka ana me kahi papa pauka epoxy e hāʻawi ana i ka hoʻopili maikaʻi loa a me ka hoʻopili ʻana i ka ʻili o ka paipu. Ma hope o kēia, aia kahi papa hoʻopili, kahi e hoʻoikaika hou ai i ka pilina ma waena o ka epoxy a me ka papa hope loa - polyethylene anti-corrosion. Hana ka papa polyethylene ma ke ʻano he pale, e pale ana i ka wai, nā kemika, a me nā mea ʻino ʻē aʻe mai ka hiki ʻana i ka ʻili o loko o ka paipu. Eia kekahi, hiki iā ia ke kū i nā mahana a hiki i 80°C, e kūpono ai no nā ʻano hana like ʻole.
Ke hoʻohālikelike ʻia me ka uhi ʻana o 2PE, ʻo ka hoʻohui ʻana o ka papa pauka epoxy i loko o nā paipu kila kalapona LSAW i uhi ʻia me 3PE e hoʻonui i ka pono holoʻokoʻa o nā waiwai anti-corrosion. Hoʻonui kēia papa hou i ke kūpaʻa a me ke kūʻē ʻana i ka ʻaʻahu a me ka haehae, e hōʻoiaʻiʻo ana e hiki i nā paipu ke kū i nā kūlana kaiapuni ʻino. ʻO ke kala maʻamau oNā paipu i uhi ʻia me 3PEhe ʻeleʻele, a pili lākou i nā kūlana honua e like me DIN30670, CAN/CSA Z245.21, a me ISO21809. Hōʻoia kēia mau kūlana paʻa e hoʻokō nā paipu i nā kūlana maikaʻi a me ka hana e pono ai, e lilo ana lākou i koho hilinaʻi no nā ʻoihana like ʻole.
Ma Botop Steel, loea mākou i ka hoʻolako ʻana i nā paipu kila kalapona LSAW kiʻekiʻe me ka uhi anti-corrosion 3PE. Loaʻa kā mākou mau paipu i nā nui like ʻole, nā papa, a me nā kikoʻī e hoʻokō i nā pono kikoʻī o kā mākou mea kūʻai aku. Me kā mākou kūpaʻa i ka maikaʻi a me ka nānā ʻana i nā kikoʻī, hōʻoia mākou e hoʻokō kā mākou mau paipu i nā kūlana ʻoihana kiʻekiʻe loa. Eia kekahi, ua uhi ʻia kā mākou mau paipu me ka FBE anti-corrosion mai loko mai, e hoʻoikaika hou ana i ko lākou kūʻē ʻana i ka corrosion. ʻAʻohe ʻawaʻawa ka uhi FBE kūloko a kōkua i ka pale ʻana i ka corrosion me ka hoʻomaikaʻi ʻana i ka nui o ke kahe o ke kinoea a me ka wai i loko o kapaipuʻO kēia ka mea e lilo ai kā mākou mau paipu kila kalapona LSAW i uhi ʻia me 3PE i koho hilinaʻi no nā ʻoihana e like me ka ʻaila a me ke kinoea, ka lako wai, a me ke kūkulu ʻana.
I ka hopena,Nā paipu kila kalapona LSAW i uhi ʻia me 3PEhāʻawi i nā pono he nui, me nā waiwai anti-corrosion kiʻekiʻe, ke kūpaʻa kiʻekiʻe, a me ke kūpaʻa ʻana i ka ʻaʻahu a me ka haehae. ʻO ka hui pū ʻana o ka papa pauka epoxy, ka papa hoʻopili, a me ka papa anti-corrosion polyethylene e hōʻoiaʻiʻo ana e hiki i nā paipu ke kū i nā kūlana ʻino, e kūpono ai lākou no nā noi like ʻole. Ma Botop Steel, haʻaheo mākou i ka hāʻawi ʻananā paipu kiʻekiʻee hoʻokō ana i nā kūlana honua a ʻoi aku ma mua o nā manaʻolana o ka mea kūʻai aku. E hoʻopukapuka i nā paipu kila kalapona LSAW i uhi ʻia me 3PE no kahi hopena pipeline hilinaʻi a lōʻihi hoʻi.
