Ipayipi elincane le-anticorrosive steel ububanzi lisetshenziswa kabanzi
I-3PE anti-corrosion kanye ne-thermal insulation insulation pipe inokusebenza okuhle kokufakwa kwe-thermal, futhi ukulahlekelwa ukushisa kungamaphesenti angama-25 kuphela amapayipi endabuko. Ukusebenza kwesikhathi eside kungonga izinsiza ezinkulu, kunciphise kakhulu izindleko zamandla, futhi kube nokumelana okuqinile kwamanzi nokugqwala. Ngaphezu kwalokho, akudingeki ukuthi ihlanganiswe nomsele wepayipi, ngakho-ke ingangcwatshwa ngokuqondile ngaphansi komhlaba noma emanzini, okuyinto elula futhi esheshayo ekwakheni, Izindleko eziphelele nazo ziphansi kakhulu. Futhi inokumelana nokugqwala okuhle kanye nokumelana nomthelela ngaphansi kwezimo zokushisa eziphansi, futhi ingangcwatshwa ngokuqondile emhlabathini oyiqhwa endaweni ethile.
Ngaphambi kokuthi isisekelo sensimbi yepayipi lensimbi ye-3PE elwa nokugqwala ingaphansi kokwelashwa okunqanda ukugqwala, ipayipi lensimbi elingena endaweni yesikhulumi sepayipi kufanele lihlolwe futhi lirekhodwe, indawo engaphandle yepayipi yensimbi izodutshulwa iqhunyiswe ukuze kukhishwe ukugqwala, bese kuthi-ke ukuhlanzeka nokujula kwehange kwendawo yangaphandle yepayipi lensimbi kuzohlolwa ukuze kubonakale ukuthi ziyahlangabezana yini nezidingo. Uma zingahlangabezani nezidingo, zizopholishwa futhi ziqeqeshwe ngesondo lokugaya ngesandla, ziboshwe ngephepha le-adhesive tape ekupheleni kwepayipi, ziphathwe ngothuli oluncane, futhi zishiswe ezingeni lokushisa elidingekayo nge-frequency medium, i-Epoxy powder spraying, i-adhesive extruder. i-side winding, i-PE extruder side winding, ukupholisa amanzi kwamapayipi avimbela ukugqwala, ukuhlonza isifutho semikhiqizo eqeqeshiwe, ipulatifomu yokubeka amapayipi kanye nokupakishwa ukuze kuthunyelwe.
Imishini emikhulu yokukhiqiza ipayipi lensimbi le-3PE elilwa nokugqwala: iplatifomu yepayipi lensimbi, iyunithi yokudonsa ipayipi, ugandaganda, imishini yokulutha ipayipi, umshini oqhuma ngamandla, inkundla yokulungisa, ulayini wokudlulisa, isithando somlilo sepayipi lensimbi, inkundla yokulungisa umshini omkhulu wokuqhuma kokudubula. umshini, umugqa wokubuyisela wokudlulisa wepayipi lensimbi yegridi yegridi, iqembu le-roller eliya phambili elisheshayo, i-roller ephuma ngokushesha, isiteji sokulungisa, njll. Ulayini wokukhiqiza wokunqanda ukugqwala wepayipi lensimbi elilwa nokugqwala ungasetshenziswa ekusebenzeni okulwa nokugqwala kwe-single- ungqimba lwe-FBE, i-FBE enezingqimba ezimbili, i-PE enezingqimba ezimbili, i-PP enezingqimba ezimbili kanye ne-3PE yepayipi lensimbi. Isilinganiso esincane sepayipi lomshini Φ 89mm, ubukhulu bepayipi lokucubungula ubukhulu Φ 3020mm, elinomthamo omkhulu wokucubungula ongaphezu kuka-350m2 / h. Ulayini wokukhiqiza uhlanganisa uhlelo lokudluliswa kwamapayipi ensimbi, uhlelo lokwelapha olungaphezulu, uhlelo lokususa uthuli lwamapayipi, isistimu yokushisisa ipayipi lensimbi, uhlelo lokufafaza nge-electrostatic, uhlelo lokuhlanganisa, uhlelo lokupholisa amanzi, uhlelo lokusika lokugcina, uhlelo olusebenzisa amanzi kanye ne-pneumatic, uhlelo lokuhlonza kanye nesistimu yokulawula kagesi.
I-3P anticorrosive spiral steel pipe evimbela ukubola: ungqimba lokuqala lwe-epoxy powder (FBE > 100um), ungqimba lwesibili lwe-adhesive (AD) 170 ~ 250um, kanye nongqimba lwesithathu lwe-polyethylene (PE) 1.8 ~ 3.7mm. Izinto ezintathu zihlanganisiwe futhi zihlanganiswe ngokuqinile nepayipi lensimbi ukuze zenze i-anti-corrosion coating enhle kakhulu. Ibanga lobubanzi bepayipi Φ 60～ Φ 1420.
Isakhiwo se-PE esinqanda ukubola kwezingqimba ezimbili sepayipi le-2PE elivimbela ukubola: ungqimba lokuqala lwe-adhesive (AD) nolwesibili lwe-polyethylene (PE). Izinto ezimbili zihlanganisiwe, futhi ukushuba kwesendlalelo ngasinye kufana nokwezingqimba ezintathu ze-PE.
