Spiral Yakanyura Arc Welding Of Polyethylene Lined Pipes
Epoxy Resin Primer
Iyo epoxy resin primer inofanirwa kuiswa muhupfu. Ukobvu hwehudiki hunosvika 60μm.
PE Adhesive
Iyo PE inonamira inogona kuiswa mune hupfu fomu kana extruded. Ukobvu hwehudiki hunosvika 140μm. iyo peel simba zvinodiwa zvinosiyana zvichienderana nekuti iyo inonamira yaiiswa sehupfu kana yakabviswa.
Polyethylene Coating
Iyo polyethylene coating inoshandiswa kungave nekupisa kana ne sleeve kana sheet extrusion. Iyo yekupfekedza inofanirwa kutonhodzwa mushure mekushandisa kudzivirira kusada deformation panguva yekufambisa. Zvichienderana nehukuru hwezita, kune akasiyana madiki makosi eiyo yakajairika yakazara coating ukobvu. Panyaya yekuwedzera ma mechanical mitoro iyo minimu layer gobvu ichawedzerwa ne 0.7mm. ukobvu hwehudiki hunopiwa mutafura 3 pazasi.
YeduPolyethylene lined pombihadzina muchetura, dzisiri corrosive uye dzisiri scaling, zvichiita kuti ive yakachengeteka uye ine hushamwari sarudzo yemvura masisitimu. Kutevedzera QB1929-93 chiyero chekupihwa kwemvura uye HG20539-92 yakajairwa, kuve nechokwadi kuti inodiwa mhando uye kuita zvinodiwa zvinosangana. Ingave ichishandiswa munzvimbo dzekugara, dzekutengeserana kana dzemaindasitiri, mapaipi edu ePolyethylene ane mitsetse akakwana kuitira kuti pave nemvura yakachena uye isina kusvibiswa.
Magadzirirwo matsva epombi yedu yePolyethylene yakamisikidzwa inosanganisa kusimba uye kusimba kwesimbi nekupikisa kwemakemikari ePolyethylene. Iyi yakasarudzika musanganiswa inopa yakanakisa dziviriro kubva mukuora, ngura uye mamwe maitiro ekuora, zvichiita kuti ive yakanakira kuisirwa pasi pevhu inoda kuratidzwa kune hunyoro uye zvakatipoteredza zvinhu. Iyo yakatsetseka uye isingapindiki pamusoro pePolyethylene lining inodzivirirawo kuvakwa kwechiyero uye sediment, kuve nechokwadi chekuyerera kwemvura isingapindike uye kuderedza zvinodiwa zvekuchengetedza.
Pamusoro pekuita kwepamusoro, mapaipi edu akaiswa Polyethylene ari nyore kuisa uye anoda kushoma kugadzirisa, kuderedza mutengo wakazara uye kuve nechokwadi chekushanda pasina kunetseka. Kuvakwa kwayo kwakasimba uye kubatanidza kwakavimbika zvakare kunovimbisa kushanda-kwemahara, kupa runyararo rwepfungwa uye kuvimbika kwenguva refu kune chero nzira yekupa mvura.
Yedu Polyethylene lined mapaipi anowanikwa muhukuru hwakasiyana uye masisitimu kuti asangane neakasiyana mapurojekiti zvinodiwa. Kungave kutsva kuisirwa kana kutsiva pombi, yedu yakazara huwandu hwesarudzo inoita kuti iwe ugone kuwana mhinduro yakakwana yezvaunoda chaizvo. Nekuzvipira kwedu kune kugona uye kugutsikana kwevatengi, unogona kuvimba kuti pombi yedu yePolyethylene yakamisikidzwa ichasangana nekupfuura zvaunotarisira zvemhando, kuita uye hupenyu hurefu.
Muchidimbu, yedu Polyethylene yakamisikidzwa pombi ndiyo yekupedzisira sarudzo yepombi yemvura yepasi pevhumasisitimu, achipa kusimba kusingaenzaniswi, kuvimbika uye kuchengeteka. Nemaitiro ayo epamusoro ekugadzira, kutevedzera zviyero zveindasitiri uye kushanda kwepamusoro, pombi yedu yePolyethylene yakamisikidzwa inoisa chiyero chitsva chemhinduro dzemvura dzepamusoro. Sarudza yedu Polyethylene yakamisikidzwa mapaipi uye unzwe mutsauko mune yechokwadi yepamusoro, yakavimbika pombi system.
