Izvo zvigadziko zve3PE anti-corrosion simbi pombi dzinosanganisira mapaipi esimbi asina musono, spiral simbi pombi, uye yakatwasuka seam simbi pombi.Iyo yetatu-layer polyethylene (3PE) anti-corrosion coating yakashandiswa zvakanyanya muindasitiri yepombi yepetroleum nekuda kwekugona kwayo kusaita ngura, kusamira kwemvura uye gasi, uye michina.Iyo anti-corrosion layer ye3PE anti-corrosion simbi pombi yakakosha pahupenyu hwemapaipi akavigwa.Mamwe mapaipi echinhu chimwe chete akavigwa pasi pevhu pasina ngura kwemakumi emakore, nepo mamwe anodonha mukati memakore mashoma.Nekuti vanoshandisa akasiyana ekunze anti-corrosion coatings.
3PE anti-corrosion simbi pombi inoreva matatu-layer chimiro polyethylene coating (MAPEC) yekunze anti-corrosion simbi pombi, iyo inowanzoshandiswa anti-corrosion pombi muChina.Dzimwe nzira dzinopesana necorrosion dzinosanganisira IPN8710, FBE epoxy powder, uye epoxy coal tar pitch.Inowanzo reva anti-corrosion yekunze kwemadziro epombi dzesimbi.
1.-Iyo polyethylene zvinhu zvinoshandiswa mu3pe simbi mapaipi ane hupenyu hurefu hwebasa, huremu hwemamorekuru, kugadzikana kwakanaka, uye kuramba kuchembera.Pasi peyakajairika tembiricha yekushanda uye kumanikidzwa, hupenyu hwesevhisi hunogona kuvimbiswa kuve pamusoro pemakore makumi mashanu.
2.-Iyo isingadziviriri ye polyethylene zvinhu inoshandiswa mu 3PE simbi pombi ine kugadzikana kwepamusoro uye inogona kurwisa kemikemikari kubva kugasi rechisikigo, liquefied gasi, artificial gasi, nezvimwewo. Makemikari ari muvhu haazove nekukanganisa kwepaipi.
3.- Iyo polyethylene zvinhu zvinoshandiswa pa3PE simbi mapaipi ane kutsemuka kurebesa kupfuura 500%.Iko kuchinjika kwe polyethylene zvinhu kunoita kuti zvive nyore kukotama.
4.- Polyethylene zvinhu zvine yakanakisa kukanganisa kupikisa uye seismic kuramba ine yakakwirira tembiricha inochinjika, inogona kushandiswa zvakachengeteka mukupisa kwe60-80.℃, uye ine kuchinjika kwakasimba kune kusaenzana kugadzikana kwepombi nheyo.Munguva yekuvaka kwechando, nekuda kwemaitiro akanaka ekupikisa kwezvinhu, mapaipi haaite brittle.
5.-Iyo polyethylene zvinhu inoshandiswa kune 3pe simbi pombi haiwedzere inorema simbi stabilizers panguva yekugadzirisa, uye zvinhu zvacho hazvina chepfu uye hazvikuvadzi.Ipombi yegirini.Polyethylene zvinhu zvinogona kushandiswazve uye hazvimbofi zvakasvibisa nharaunda.
6.- Iyo polyethylene zvinhu zvinoshandiswa munguva ichangobva kugadzirwa inodzoreredza moto uye anti-static 3pe simbi pombi yakakodzera nzvimbo dzinopisa uye dzinoputika.
7.- Iyo yakachengeteka uye yakavimbika nzira yekubatanidza ye polyethylene zvinhu zvinoshandiswa mu 3PE simbi pombi inonyanya kupisa kunyunguduka kana kunyungudika kwemagetsi kunyungudika, iyo inonyanya kuchengetedza kuenderana kweiyo interface zvinhu, chimiro, uye pombi muviri, kuwana kubatanidzwa kwejoint uye pombi, zvinobudirira. kuramba circumferential stress.Axial tensile stress uye oblique stress inokonzerwa nekumanikidzwa kwemukati, uye hapana kunetseka kwemvura kana kubuda kwemhepo.
8.- Iyo polyethylene zvinhu zvinoshandiswa 3pe pombi dzesimbi dzakareruka, dziri nyore kushanda, uye dziri nyore kugadzira, 1/8 chete yepombi yesimbi.Iyi welding process iri nyore, inokurumidza, iri nyore kushanda, iri nyore kukotama, ine mutengo wakaderera uye zvakakosha zvehupfumi.
Sokutungamirira simbi pombi mutengesi & mugadziri, JINBAICHENG anogona kupamapaipi esimbi asina musono, pombi dzesimbi dzakatendereka, uye mapaipi esimbi akatwasuka ne 3PE Anti-corrosive Solution yemapurojekiti edu epombi.Bata nesu nemutengo wakanakisa:https://www.sdjbcmetal.com/steel-pipe-series/ email:jinbaichengmetal@gmail.com kana WhatsApp pahttps://wa.me/18854809715
