Isimbozo Sangaphandle Se-3LPE DIN 30670 Isimbozo Sangaphakathi Se-FBE
Incazelo Yomkhiqizo
I-Cangzhou Spiral Steel Pipes Group Co., Ltd inemigqa yokukhiqiza emine yokuvimbela ukugqwala kanye nokushisa ukuze yenze ungqimba lwe-3LPE kanye nongqimba lwe-FBE. Ububanzi obukhulu bangaphandle bungaba ngu-2600mm.
Lezi zingubo zifanelekela ukuvikela amapayipi ensimbi agqitshwe noma angaphansi kwamanzi emazingeni okushisa aklanywe ngomklamo kusukela ku--40℃ kuya ku-+80℃.
Indinganiso yamanje icacisa izidingo zokumboza okusetshenziswa kumapayipi ensimbi ahlanganisiwe nge-spirally kanye nezinto zokufakelwa ezisetshenziselwa ukwakha amapayipi okuhambisa uketshezi noma amagesi.
Ukusebenzisa le ndinganiso kuqinisekisa ukuthi isembozo se-PE sinikeza isivikelo esanele emithwalweni yokushisa neyekhemikhali eyenzeka ngesikhathi sokusebenza, ukuthuthwa, ukugcinwa kanye nokufakwa.
Izembozo ezikhishwe zakhiwe izendlalelo ezintathu: i-epoxy resin primer, i-PE glue kanye nesendlalelo sangaphandle se-polyethylene ekhishwe. I-epoxy resin primer isetshenziswa njengempuphu. I-glue ingasetshenziswa njengempuphu noma ngokuyikhipha. Kwezembozo ezikhishwe, kwenziwa umehluko phakathi kokukhipha imikhono kanye nokukhipha ishidi. Izembozo ze-polyethylene ezisikiwe ziyizinhlelo ezilodwa noma eziningi. Impuphu ye-polyethylene ihlanganiswa nengxenye eshisiwe kusengaphambili kuze kube yilapho kufinyelelwa ubukhulu be-coating obufunayo.
I-primer ye-resin ye-epoxy
I-primer ye-epoxy resin kufanele ifakwe ngendlela yempuphu. Ubukhulu bengqimba obuncane bungu-60μm.
Ingcina ye-PE
I-PE adhesive ingasetshenziswa ngesimo sempuphu noma ikhishwe. Ubukhulu obuncane bengqimba bungu-140μm. Izidingo zamandla e-peel ziyahlukahluka kuye ngokuthi i-adhesive isetshenziswe njengempuphu noma ikhishwe.
Ukugqoka kwe-polyethylene
Isembozo se-polyethylene sisetshenziswa ngokusila noma ngokusikhipha ngesleeve noma ngeshidi. Isembozo kufanele sipholiswe ngemva kokusetshenziswa ukuze kugwenywe ukuguquka okungafuneki ngesikhathi sokuthuthwa. Kuye ngobukhulu obujwayelekile, kunezinhlobo ezihlukile ezincane zobukhulu obujwayelekile besembozo. Uma kwenzeka imithwalo yemishini ekhuphukile, ubukhulu besembozo obuncane buzokhushulwa ngo-0.7mm. Ubukhulu besembozo obuncane bunikezwe kuthebula 3 ngezansi.
