Perforated steel strip PE ipayipi Ukuze igesi
Isicelo
Ipayipi elihlanganisiwe lensimbi elinezimbobo le-polyethylene lenziwe ngensimbi egoqelwe ebandayo kanye ne-thermoplastics njengezinto zokusetshenziswa, futhi amapayipi ensimbi anezindonga ezincane anezimbobo akhiwa i-argon arc butt welding noma i-plasma spiral welding asetshenziswa njengeziqinisi.Izendlalelo zangaphandle nezingaphakathi ziyi-thermoplastic ehlanganisiwe enezinhlangothi ezimbili.Uhlobo olusha lwepayipi lokucindezela eliyinhlanganisela, Ngenxa yokuthi ipayipi lensimbi elinezimbobo ezincane elinezindonga eziqinile ligoqwe nge-thermoplastic eqhubekayo, leli payipi eliyinhlanganisela aligcini nje ngokunqoba ukushiyeka okukhona kwamapayipi ensimbi namapayipi epulasitiki, kodwa futhi linokuqina kwamapayipi ensimbi nokugqwala. ukumelana namapayipi epulasitiki.Kuyisixazululo sezimboni ze-petroleum kanye namakhemikhali.Kuyipayipi elidingeka ngokuphuthumayo lamapayipi amakhulu naphakathi nendawo aqinile emkhakheni wemithi, ukudla, izimayini, igesi kanye neminye imikhakha.Kuphinde kube yimpumelelo yezinguquko kwezobuchwepheshe ukuxazulula ipayipi elikhulu lokwakha kanye nokuhlinzekwa kwamanzi kamasipala.Iwuhlobo olusha lwepayipi eliyinhlanganisela ku-21stikhulu leminyaka.
Izici
Ukusebenza okuhlanzekile
Inkomba yokuhlanzeka nokuphepha kwepayipi eliyinhlanganisela yensimbi enembobo enezimbobo ihlangabezana nezimfuneko ze-GB9687 "Izinga Lenhlanzeko Lemikhiqizo Ebunjiwe Ye-Polyethylene Yephakheji Yokudla" kanye ne-GВ/Т17219 "Izinga Lokuhlola Ukuphepha Kwezisetshenziswa Zokusabalalisa Amanzi Okuphuza kanye Nezisetshenziswa Nezinto Zokuzivikela". Ingcono kakhulu esikhundleni sepayipi likathayela kanye nepayipi lensimbi.
Udonga lwangaphakathi olubushelelezi nokusebenza kokujikeleza
Udonga lwangaphakathi lwepayipi eliyinhlanganisela yensimbi yensimbi enemeshi lubushelelezi kakhulu, futhi ubulukhuni obuphelele buyi-1/20 kuphela yaleyo yepayipi lensimbi.Umthamo wokudlulisa ngaphansi kwezimo ezifanayo cishe u-30% ngaphezu kwepayipi lensimbi.
