Ipayipi lensimbi lepulasitiki elifakwe uthayela lensimbi engenamthungo kanye nepayipi lensimbi elishiselwe lisetshenziswa njengepayipi lesisekelo.Udonga lwangaphakathi lufakwe ipayipi ye-polyethylene (PE) yebanga lokudla enobubanzi obufanayo nepayipi le-galvanized ngemva kokukhishwa kwezimbambo zokushisela.Ukushuba kolwelwesi lwe-polyethylene kuzohlangabezana nezinga le-HG/T 20538-2016.
Ububanzi Besicelo
(Ukuvikelwa kwemvelo) Ubuchwepheshe bepayipi lensimbi yensimbi enomugqa elifakwe ipayipi lensimbi lepulasitiki lizuze njengefa izinzuzo zepayipi lensimbi nepayipi lepulasitiki, futhi ngokuya ngesidingo semakethe, inqubo yokukhiqiza, izinyathelo zokulwa nokugqwala, ukuxhumana, ukonga kanye nezinye izici eziningi ezinengqondo. ukuklanywa kwepayipi ngemva kokuhlaziywa okuphelele.Ngakho-ke, ipayipi inezici eziningi zobuchwepheshe, ezisetshenziswa kabanzi kuzo zonke izinhlobo zezakhiwo ezibandayo kanye nohlelo lokuhlinzeka ngamanzi ashisayo.Imodi yokuxhuma inoxhumano olukhethekile lwendandatho ye-clamp, uxhumano lwe-groove (i-clamp) noma uxhumano lwe-wire buckle, inqubo yokwakha ifana nokuxhumeka kwe-groove yepayipi yensimbi kanye nokuxhumeka kwe-wire buckle.
Ngokuduma kokuqwashisa kwabantu ngokuvikelwa kwemvelo kanye nempilo, amapayipi amasha okuphakela amanzi emvelo aphuma njengehlumela loqalo ngemva kwemvula, futhi kunezinhlobo eziningi kakhulu ongazibala.Plastic steel pipe lined ifa izinzuzo steel ipayipi kanye ipayipi plastic, kodwa ulahle imibi yabo.Okunye kokuqukethwe okubaluleke kakhulu ekwakhiweni kwamapayipi ukucacisa ubukhulu bodonga lwepayipi ngokunengqondo ngokwemibandela nezidingo zokusetshenziswa, futhi le parameter ithinta ngqo ukusebenza kwezindleko zomkhiqizo.Idizayini eyingqayizivele yodonga lwepayipi yensimbi efakwe ulayini ihlanganisa ugqinsi lwamapayipi epulasitiki angaphakathi nogqinsi lwamapayipi ashiselwe ngaphandle, okunquma uchungechunge lwezimpawu zobuchwepheshe:
1. Uhlu olubanzi lohlelo, imininingwane ephelele nezinhlobonhlobo;
2. Ubuchwepheshe bokukhiqiza obuyingqayizivele;
3. Imodi yokuxhumana ethembekile nesheshayo;
4. Izinyathelo zokuvimbela ukugqwala kokugqwala ziphelele, zinhle;
5. umklamo wangaphandle wepayipi elihlanganisiwe odongeni unengqondo;
6. Ubukhulu bodonga lwepayipi yepulasitiki yangaphakathi bunengqondo ukuqinisekisa ububanzi;
7. ukonga ugesi nokuvikelwa kwemvelo, amandla amakhulu okuthuthuka;
Plastic camera steel pipe, eyaziwa nangokuthi plastic camera pipe, steel-plastic composite pipe, plastic camera esiyinhlanganisela ipayipi yensimbi, iyipayipi steel njengoba matrix, ngokusebenzisa sishaye, rolling, ukucwilisa, ukumunca inqubo epayipini lensimbi (ipayipi ngezansi) ngaphakathi. ingaphezulu longqimba longqimba lwepulasitiki lwe-anticorrosive noma endaweni engaphakathi nangaphandle yepayipi lensimbi eliyinhlanganisela yepulasitiki.Ipayipi lensimbi ehlanganiswe nepulasitiki inokumelana nokugqwala okuhle kakhulu kanye nokumelana nokungqubuzana okuncane.Ipayipi lensimbi yensimbi ye-epoxy resin ilungele ukuphakelwa kwamanzi kanye nokukhipha amanzi, amanzi olwandle, amanzi afudumele, uwoyela, igesi nezinye izinto zokuhamba zemidiya, ipayipi lensimbi le-PVC elihlanganiswe ne-PVC lilungele ukudonsa amanzi, amanzi olwandle, uwoyela, igesi nokunye ukuthuthwa kwabezindaba.
Izici Zomkhiqizo
Ipayipi lensimbi elakhiwe lenziwe nge-PE (i-polyethylene eguquliwe) yepulasitiki yokucwilisa eshisayo noma i-EP(i-epoxy resin) yemikhiqizo yokunamathela yangaphakathi nangaphandle, enokumelana nokugqwala okuhle kakhulu.Ngesikhathi esifanayo, i-coating ngokwayo ine-insulation enhle kagesi, akukho ukugqwala kagesi.Ukumuncwa kwamanzi aphansi, amandla aphezulu emishini, i-coefficient encane ye-friction, ingafinyelela inhloso yokusetshenziswa isikhathi eside.Kungase futhi kuvimbele ngempumelelo ukulimala kwezimpande zezitshalo nokucindezeleka kwemvelo kwenhlabathi.Ukuxhumana okulula nokugcinwa okulula.
Inzuzo Yomkhiqizo
1. Ijwayelane nendawo engcwatshwe futhi enomswakama, futhi ingamelana nezinga lokushisa eliphezulu neliphansi kakhulu.
2. Ikhono eliqinile lokulwa nokuphazamiseka, uma livalwe ngeshubhu lensimbi njengomkhono wekhebula, lingavikela ngempumelelo ukuphazamiseka kwesignali yangaphandle.
3. Amandla okucindezela okuhle, ukucindezela okukhulu kufika ku-6Mpa.
4. Ukusebenza okuhle kokuvikela, njengeshubhu lokuvikela ucingo ngeke kwenzeke ukuvuza.
5. Ayikho i-burr, i-tube wall ebushelelezi, efanelekile ukwakhiwa kwesikhathi sokugqoka ucingo noma ikhebula.
