Kana zvasvikakugadzira mapaipi, kuve nechokwadi chekugara kwavo uye kuramba kurwisa ngura kwakakosha zvakanyanya.LSAW kabhoni simbi mapaipi, inozivikanwawo seLongitudinal Submerged ArcWelding pombi, isarudzo yakakurumbira nekuda kwesimba ravo repamusoro uye kuvimbika.Kuti uwedzere kusimba kwekusaora kwadzo, mapaipi aya anogona kuputirwa neatatu-layer chimiro polyethylene anti-corrosion inozivikanwa se3PE.Mune ino blog, isu tichaongorora mabhenefiti ekushandisa3PE yakavharwa LSAW kabhoni simbi mapaipiuye nei ivo vari sarudzo yakanaka kune akasiyana maindasitiri.
Iyo 3PE anti-corrosion coating imhinduro yakavimbika inodzivirira LSAW kabhoni simbi mapaipi kubva pakuora uye kuwedzera hupenyu hwawo.Iyo 3PE chimiro chine matatu akaturikidzana, kutanga ne epoxy poda layer inopa yakanakisa adhesion uye kusungirira pamusoro pepombi.Izvi zvinoteverwa neadhesive layer, iyo inowedzera kusimbisa chisungo pakati pe epoxy uye yekupedzisira layer - polyethylene anti-corrosion.Iyo polyethylene layer inoshanda sechivharo, ichidzivirira mvura, makemikari, uye zvimwe zvinhu zvinoparadza kuti zvisasvike mukati mepombi.Uyezve, inokwanisa kumira tembiricha inosvika 80°C, ichiita kuti ikwane kune zvakasiyana siyana zvekushandisa.
Kuenzaniswa neiyo 2PE coating, kuwedzerwa kweiyo epoxy poda layer mu3PE yakavharwa LSAW carbon steel mapaipi inowedzera kushanda kwese kweiyo anti-corrosion properties.Iyi yekuwedzera layer inosimudzira kusimba uye kuramba kupfeka uye kubvaruka, kuve nechokwadi chekuti mapaipi anogona kumira nemamiriro ekunze akaomarara.Ruvara rwakajairika rwe3PE yakavharwa mapaipiitema, uye vanoomerera kumitemo yenyika dzakaita seDIN30670, CAN/CSA Z245.21, uye ISO21809.Aya maitiro akaomesesa anovimbisa kuti mapaipi anosangana nemhando inodiwa uye maitiro ekuita, zvichiita kuti ive sarudzo yakavimbika kune akasiyana maindasitiri.
PaBotop Steel, isu tine hunyanzvi hwekupa emhando yepamusoro LSAW kabhoni simbi mapaipi ane 3PE anti-corrosion coating.Mapombi edu anowanikwa muhukuru hwakasiyana, mamakisi, uye zvakatemwa kuti zvienderane nezvinodiwa chaizvo nevatengi vedu.Nekuzvipira kwedu kune kugona uye kutarisisa kune zvakadzama, isu tinoona kuti mapaipi edu anosangana nepamusoro indasitiri zviyero.Pamusoro pezvo, mapaipi edu akaputirwa neFBE anti-corrosion kubva mukati, zvichiwedzera kuwedzera kusimba kwavo mukuora.Iyo yemukati FBE coating haina chepfu uye inobatsira kudzivirira ngura uchivandudza kuyerera kwegasi uye mvura mukati mepipeline.Izvi zvinoita kuti yedu 3PE yakavharwa LSAW kabhoni simbi mapaipi sarudzo yakavimbika kune maindasitiri akadai seoiri negesi, mvura, uye kuvaka.
Mukupedzisa,3PE yakavharwa LSAW kabhoni simbi mapaipiinopa akawanda mabhenefiti, anosanganisira epamusoro anti-corrosion zvivakwa, kusimba kwepamusoro, uye kuramba kusakara uye kubvaruka.Iko kusanganiswa kwe epoxy poda layer, adhesive layer, uye polyethylene anti-corrosion layer inovimbisa kuti mapaipi anogona kumira nemamiriro ezvinhu akaomarara, achiita kuti akwanise kushandiswa kwakasiyana.PaBotop Steel, tinodada nekupamapaipi emhando yepamusorozvinosangana nezviyero zvepasi rose uye zvinopfuura zvinotarisirwa nevatengi.Isai mari mu3PE yakavharwa LSAW kabhoni simbi mapaipi kune yakavimbika uye inogara kwenguva refu yepombi mhinduro.
