Mukushandiswa kwemaindasitiri, kunyanya muchikamu chemafuta negasi, kuvimbika kwemapaipi esimbi kwakakosha. Imwe yenzira dzinoshanda kwazvo dzekuona kuti mapaipi aya anogara kwenguva refu uye akasimba ndeyekushandisa machira e epoxy (FBE) akabatanidzwa. Kunzwisisa mitemo yeFBE coating kwakakosha kune chero ani zvake anobatanidzwa mukutenga, kuisa kana kugadzirisa mapaipi emvura esimbi nezvigadziko.
Mapendi eFBE anonyanya kushandiswa pamapaipi esimbi akasiyana-siyana, anosanganisira mapaipi eSSAW (Spiral Submerged Arc Welded), mapaipi eERW (Electric Resistance Welded), mapaipi eLSAW (Longitudinal Submerged Arc Welded), mapaipi asina musono, uye zvinhu zvakasiyana-siyana zvakaita semagokora, matinji, uye zvinoderedza kupisa. Chinangwa chikuru chependi idzi ndechekudzivirira ngura, izvo zvakakosha kuchengetedza chimiro chepaipi kwenguva refu.
ChiiKuputira kweFBE?
Kuputira FBE ihupfu hwe epoxy hunoiswa pamusoro pepombi yesimbi. Maitiro ekushandisa anosanganisira kupisa pombi kusvika patembiricha yakatarwa wozoisa hupfu hwe epoxy, hunonyunguduka hwoita chisungo chakasimba nepamusoro pepombi yesimbi. Maitiro aya anogadzira hupfu hwakatsetseka, hwakasimba uye hunodzivirira makemikari hunogona kumira mamiriro ekunze akaoma.
Kukosha kwemitemo yeFBE coating
Kutevedzera mitemo yeFBE coating kwakakosha nekuda kwezvikonzero zvinotevera:
1. Kudzivirira ngura: Basa guru reFBE coating nderekudzivirira simbi kubva mukuora. Mitemo yakakodzera inoita kuti coating ishandiswe nemazvo uye inosangana nezvinodiwa pakukora uye kunamira kuti ipe dziviriro yakakwana.
2. Kuvimbisa Hunhu Hwakanaka: Nekutevedzera mitemo yakatarwa, vagadziri vanogona kuvimbisa hunhu hwezvigadzirwa zvavo. Izvi zvakakosha zvikuru kumakambani anogadzira mapaipi esimbi akawanda, semuenzaniso, kambani ine midziyo inosvika mamiriyoni mazana matanhatu nemakumi masere eyuan, inoburitsa matani zviuru mazana mana emapaipi esimbi anotenderera pagore, uye inoburitsa mari inosvika mabhiriyoni zana nemazana masere eyuan.
3. Kutevedzera mitemo: Maindasitiri mazhinji anotongwa zvakasimba nezvezvinhu zvavanoshandisa uye maitiro avanoita. Kutevedzera mitemo yeFBE coating kunobatsira makambani kudzivirira nyaya dzemutemo uye kuchengetedza mukurumbira wavo pamusika.
4. Inogara kwenguva refu uye yakavimbika: Kushandisa zvakanaka FBE coating kunogona kuwedzera hupenyu hwemapaipi esimbi zvakanyanya. Kuvimbika uku kwakakosha kumaindasitiri anovimba nemapaipi aya kutakura mvura, mafuta negasi.
Pakufunga nezvemachira eFBE, zvakakosha kunzwisisa zvinodiwa pakushandisa kwawo:
- ASTM D638: Mutemo uyu unotsanangura hunhu hwekudhonza kwemapurasitiki (kusanganisira machira eFBE) kuti ave nechokwadi chekuti anokwanisa kutsungirira kushushikana kunosangana nako pakushandiswa.
- ASTM D3359: Iyi chiyero inoedza kunamira kwejira iri pachigadziko, izvo zvakakosha pakuona kuti jira reFBE rinoramba rakakwana nekufamba kwenguva.
- AWWA C213: Mutemo uyu unotarisa zvakananga zvinodiwa zvekubatanidza epoxy ne fusion-bonded epoxy coatings yemapaipi emvura esimbi, zvichipa gwara rekushandisa, kuongorora, uye kuyedza.
mukupedzisa
Muchidimbu, kunzwisisa mitemo yeFBE coating kwakakosha kune chero munhu ari muindasitiri yemapombi esimbi. Zvichitarisa pakudzivirira ngura, kuvimbisa mhando, uye kutevedzera mitemo, mitemo iyi inoita basa rakakosha mukuona kuti mapaipi esimbi nemidziyo yawo zvinoshanda uye kuvimbika. Makambani anokoshesa kutevedzera mitemo iyi, senge ayo ane hunyanzvi hwekugadzira zvinhu, haangogone chete kuvandudza mhando yechigadzirwa asiwo kusimbisa chinzvimbo chavo mumusika unokwikwidzana. Sezvo kudiwa kwemapombi esimbi akasimba uye akavimbika kuri kuramba kuchikura, kukosha kwemapombi esimbi akasimba uye mitemo yekushandisa kwawo kucharamba kuchikura.
