Ke hiki maike kukulu ana i na paipu, e hōʻoia ana i ko lākou kūpaʻa a me ke kū'ē i ka corrosion he mea nui loa.LSAW paipu kila kalapona, i ʻike ʻia ʻo Longitudinal Submerged ArcPaipu wiliwili, he koho kaulana ma muli o ko lākou ikaika kiʻekiʻe a me ka hilinaʻi.No ka hoʻonui hou ʻana i ko lākou kūpaʻa ʻino, hiki ke uhi ʻia kēia mau paipu me kahi ʻano polyethylene anti-corrosion ʻekolu-layer i kapa ʻia ʻo 3PE.Ma kēia blog, e ʻimi mākou i nā pono o ka hoʻohana ʻana3PE i uhi ʻia i nā paipu kila kalapona LSAWa no ke aha lākou he koho maikaʻi loa no nā ʻoihana like ʻole.
ʻO ka 3PE anti-corrosion coating he hopena hilinaʻi ia e pale ai i nā paipu kila kalapona LSAW mai ka corrosion a hoʻonui i ko lākou ola.ʻO ka hale 3PE he ʻekolu mau papa, e hoʻomaka ana me kahi papa lepo epoxy e hāʻawi ai i ka hoʻopili maikaʻi a me ka hoʻopaʻa ʻana i ka ʻili o ka paipu.Hoʻopili ʻia kēia me kahi papa hoʻopili, e hoʻoikaika hou i ka pilina ma waena o ka epoxy a me ka papa hope - polyethylene anti-corrosion.Hana ʻia 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 pale i nā mahana a hiki i 80 ° C, e kūpono ana i nā ʻano hana like ʻole.
Ke hoʻohālikelike ʻia me ka uhi ʻana o 2PE, ʻo ka hoʻohui ʻana o ka papa epoxy pauka ma 3PE i uhi ʻia i nā paipu kila kalapona LSAW e hoʻonui i ka pono holoʻokoʻa o nā waiwai anti-corrosion.Hoʻonui kēia papa hou i ka lōʻihi a me ke kū'ē ʻana i ka ʻaʻahu a me ka waimaka, e hōʻoia ana e hiki i nā paipu ke kū i nā kūlana kūlohelohe koʻikoʻi.ʻO ke kala maʻamau o3PE i uhi ʻia nā paipuʻeleʻele, a pili lākou i nā kūlana honua e like me DIN30670, CAN/CSA Z245.21, a me ISO21809.ʻO kēia mau kūlana koʻikoʻi e hōʻoiaʻiʻo i ka hoʻokō ʻana o nā paipu i ka maikaʻi i koi ʻia a me nā koina hana, e hoʻolilo iā lākou i koho hilinaʻi no nā ʻoihana like ʻole.
Ma Botop Steel, hoʻolaha mākou i ka hāʻawi ʻana i nā paipu kila kalapona LSAW kiʻekiʻe me ka 3PE anti-corrosion coating.Loaʻa kā mākou paipu i nā nui like ʻole, nā māka, a me nā kikoʻī e hoʻokō i nā pono kikoʻī o kā mākou mea kūʻai.Me kā mākou kūpaʻa i ka maikaʻi a me ka nānā ʻana i nā kikoʻī, hōʻoia mākou e hoʻokō kā mākou paipu i nā kūlana ʻoihana kiʻekiʻe.Hoʻohui ʻia, ua uhi ʻia kā mākou paipu me ka FBE anti-corrosion mai loko mai, e hoʻonui hou ana i ko lākou kūʻē ʻana i ka corrosion.ʻAʻole ʻawaʻawa ka uhi FBE kūloko a kōkua i ka pale ʻana i ka ʻino ʻoiai e hoʻomaikaʻi ana i ke kahe kahe o ke kinoea a me ka wai i loko o kapaipu.Hana kēia i kā mākou mau paipu kalapona kalapona 3PE i uhi ʻia i kahi koho hilinaʻi no nā ʻoihana e like me ka aila a me ke kinoea, ka wai, a me ke kūkulu ʻana.
I ka hopena,3PE i uhi ʻia i nā paipu kila kalapona LSAWhāʻawi i nā pono he nui, me nā waiwai anti-corrosion kiʻekiʻe, ka lōʻihi kiʻekiʻe, a me ke kūʻē ʻana i ka lole a me ka waimaka.ʻO ka hui pū ʻana o ka epoxy powder layer, adhesive layer, a me ka polyethylene anti-corrosion layer e hōʻoia i ka hiki i nā paipu ke kū i nā kūlana koʻikoʻi, e kūpono iā lākou no nā noi like ʻole.Ma Botop Steel, haʻaheo mākou i ka hāʻawi ʻananā paipu kūlana kiʻekiʻee kū ana i nā kūlana honua a ʻoi aku i ka manaʻo o ka mea kūʻai aku.Hoʻokomo i nā paipu kila LSAW i uhi ʻia me 3PE no ka hoʻonā paipu kūpaʻa a lōʻihi.
