Tupu itinye mkpuchi anticorrosive, elu nke ọkpọkọ ígwè kwesịrị kpochaa nke griiz, unyi na ihe mgbakwunye ndị ọzọ, a ga-edozikwa elu ya mgbe ọ gbasasịrị ọkpọkọ ígwè na okpomọkụ nke 40-60 ℃. The elu pretreatment àgwà kwesịrị izute chọrọ nke Sa2.5 larịị nke "Surface ajari Grade na nchara mwepụ Grade nke ígwè Tupu eserese" GB / T 8923, na arịlịka ụkpụrụ omimi kwesịrị iru 50μm-75μm.

Jiri isi iyi ọkụ na-enweghị mmetọ na-ekpo ọkụ nchara ígwè ka ọ bụrụ okpomọkụ mkpuchi kwesịrị ekwesị, ma tinyekwa mkpuchi ntụ ntụ epoxy n'elu ọkpọ ígwè. A ghaghị itinye nrapado ahụ n'oge usoro ọgwụgwọ epoxy ntụ ntụ. Enwere ike kpuchie oyi akwa polyethylene site na iji usoro extrusion ogologo ma ọ bụ usoro mkpuchi n'akụkụ. Maka ọkpọkọ ígwè nwere dayameta ọnụ karịa 500mm, a na-atụ aro usoro mkpuchi n'akụkụ. Mgbe ị na-eji usoro mkpuchi nke dị n'akụkụ, hụ na polyethylene dị n'akụkụ abụọ nke ihe mkpuchi ahụ na polyethylene dị n'akụkụ abụọ nke weld na-agbanye kpamkpam ma na-ejikọta ya, ma gbochie mkpuchi mkpuchi polyethylene. Mgbe ị na-eji usoro extrusion ogologo oge, e kwesịghị inwe oghere n'akụkụ abụọ nke weld. Mgbe a na-ekpuchi akwa polyethylene, hụ na a na-agwọta mkpuchi epoxy fused kpamkpam, wee mee ka ọ dị jụụ na mmiri na-ekpo ọkụ nchara ígwè adịghị elu karịa 60 ℃.

Mgbe a na-ahụ ntụpọ na pipeline 3PE, maka mmebi na-erughị ma ọ bụ hà nhata 30mm, a na-atụ aro ka iji radieshon nrụzi polyethylene cross-linked. Mgbe ị na-arụzi, buru ụzọ wepụ ihe ruru unyi na ebe mebiri emebi ma mebie oyi akwa polyethylene. Mgbe ahụ, belata oyi akwa polyethylene na mpaghara mebiri emebi n'ime gburugburu, na nsọtụ kwesịrị ịtụgharị ka ọ bụrụ akụkụ na-adịghị mma. Jupụta oghere ahụ na nrapado dabara na ihe nrụzi ahụ, wee rapara n'ihe nrụzi ahụ. Ogo nke ihe nrụzi ahụ kwesịrị ijide n'aka na ọnụ ya dị ma ọ dịkarịa ala 100mm site na nsọtụ oghere dị na oyi akwa polyethylene. Mgbe ị na-arapara ihe nkedo ahụ, kpoo ya ka ọ na-akpụgharị ya na ihe mkpuchi ma ọ bụ jiri aka na-ekpo ọkụ na-ekpochapụ ya iji wepụ ikuku ruo mgbe nrapado dị n'akụkụ ihe nrụzi ahụ ga-ejubiga ókè.

Maka mmebi ihe karịrị 30mm, buru ụzọ wepụ ihe ruru unyi n'ebe ahụ mebiri emebi, mee ka oyi akwa polyethylene mee ka ọ dịkwuo mma, ma bee polyethylene oyi akwa na ebe mebiri emebi n'ime gburugburu, na nsọtụ kwesịrị ịtụgharị ka ọ bụrụ akụkụ na-adịghị mma. Jupụta oghere ahụ na nrapado dabara na ihe nrụzi ahụ, wee rapara n'ihe nrụzi ahụ. N'ikpeazụ, kechie teepu na-ekpo ọkụ na-ekpo ọkụ n'akụkụ ebe a na-arụzi ihe, na obosara mkpuchi kwesịrị ịdịkarịa ala 50mm karịa akụkụ nke ọ bụla nke ihe nrụzi ahụ.

N'aka nke ọzọ, enwere ike ihicha elu elu nke mbụ, mgbe ahụ enwere ike iji mkpuchi epoxy nke nwere akụkụ abụọ maka mgbochi corrosion. Okpokoro ihe nkiri akọrọ kwesịrị ịdị ka nke pipeline isi, mgbe ahụ, enwere ike itinye ihe nrụzi ma ọ bụ teepu na-ekpo ọkụ.
