TPEP anti-corrosion pipeline coating anti-corrosion yog siv cov xim kom sib npaug thiab ntom ntom ntawm cov yeeb nkab hlau tom qab derusting, thiaj li cais nws los ntawm ntau yam corrosive media, uas yog ib qho ntawm cov txheej txheem ntawm steel yeeb nkab los tiv thaiv corrosion. . TPEP anti-corrosion pipeline anti-corrosion txheej yog nce siv cov ntaub ntawv sib xyaw lossis cov qauv sib xyaw. Cov ntaub ntawv thiab cov qauv no yuav tsum muaj cov khoom zoo dielectric, lub cev muaj zog, cov khoom siv tshuaj lom neeg ruaj khov, thiab qhov kub thiab txias.
(1) Anti-corrosion txheej rau ntawm phab ntsa sab nrauv: hom thiab tej yam kev mob ntawm kev siv cov ntaub ntawv txheej ntawm cov phab ntsa sab nrauv ntawm cov kav dej.
(2) Anti-corrosion txheej rau ntawm phab ntsa sab hauv: ib zaj duab xis siv rau sab hauv phab ntsa ntawm cov yeeb nkab txhawm rau tiv thaiv corrosion hauv cov yeeb nkab, txo kev sib txhuam, thiab ua kom muaj zog. Cov khoom siv feem ntau yog epoxy resin hmoov thiab polyamide epoxy resin, thiab txheej thickness yog 200-800 microns. Txhawm rau kom ntseeg tau tias cov txheej txheem ruaj khov rau cov yeeb nkab phab ntsa, kev kho saum npoo yuav tsum tau nqa tawm ntawm phab ntsa hauv cov yeeb nkab. Txij li thaum xyoo 1970, cov khoom siv tib yam tau siv rau cov txheej txheem ntawm cov yeeb nkab sab hauv thiab sab nrauv phab ntsa, kom cov txheej txheem ntawm cov yeeb nkab sab hauv thiab sab nrauv tuaj yeem ua tiav tib lub sijhawm.
TPEP anti-corrosion pipeline yog ib qho khoom kho dua tshiab raws li txheej txheej polyethylene epoxy composite steel yeeb nkab. Nws yog ib qho zoo heev steel yeeb nkab los tiv thaiv corrosion rau faus cov kav dej ntev. Tshiab anti-corrosion ntau lawm kab rau loj-inch pipelines. Sab nrauv phab ntsa txais cov txheej txheem thermal fusion winding, hauv qab txheej txheej epoxy resin, nruab nrab txheej nplaum, thiab txheej txheej polyethylene tsim peb txheej los tiv thaiv corrosion. Sab hauv phab ntsa txais cov thermal txau epoxy hmoov los tiv thaiv corrosion. Tom qab kub kub thiab sintering, nws yog tusyees coated rau saum npoo ntawm cov yeeb nkab lub cev los tsim ib tug steel-yas alloy txheej, hu ua TPEP steel yeeb nkab, (T, thawj tsab ntawv ntawm peb nyob rau hauv lus Askiv, PE yog hais txog polyethylene. , thiab EP hais txog epoxy resin). Txhim kho cov txheej txheej adhesion thiab txheej thickness, thiab txhim khu lub peev xwm ntawm kev sib tsoo thiab tiv thaiv corrosion. Tus nqi ntawm TPEP steel yeeb nkab yog yuav luag zoo ib yam li ntawm ib txheej polyethylene inner fusion bonded epoxy composite steel yeeb nkab, thiab corrosion kuj yog nce los ntawm 3-5 zaug.
Qhov zoo ntawm TPEP anti-corrosion pipeline:
1. TPEP anti-corrosion pipelines yog zoo heev los tiv thaiv corrosion khoom nyob rau hauv tsev thiab txawv teb chaws, nrog ib tug kev pab cuam lub neej ntawm ntau tshaj 50 xyoo. Sab nrauv 3PE tiv thaiv corrosion yog qhov kev taw qhia ntawm Lavxias teb sab technology, uas muaj keeb kwm ze li ntawm 100 xyoo. Cov txheej txheej sab hauv yog thermal fusion epoxy hmoov txheej, thiab cov khoom siv Japanese tuaj yeem muaj keeb kwm ntawm 70 xyoo.
2. Sab hauv phab ntsa yog du, thiab roughness yog 0.0081-0.0091 (kuaj los ntawm Academy of Sciences). Lub taub hau poob yog me me. Rau kev xa cov nruab nrab nrog tib tus nqi ntws, lub caliber tuaj yeem raug txo los ntawm ib theem.
3. Muaj peev xwm ua kom haum rau hauv av. Cov yeeb nkab steel muaj zog yooj.
4. Yooj yim thiab txhim khu kev qha installation. Qhov ntev ntawm ib lub yeeb nkab tuaj yeem ncav cuag 12 meters, thiab qhov chaw nres nkoj sib txuas yog txo los ntawm ib nrab.
5. Sab hauv phab ntsa yog du thiab tsis scale.
