Upamhi hwemapaipi eCHUANGRONG PE hunobva pa20 mm kusvika 1600 mm, uye kune mhando dzakawanda dzezvishandiso zviripo kuti vatengi vasarudze. Mapaipi ePE kana zvishandiso zvinobatanidzwa nekupisa kana nezvishandiso zvemakanika.
Pombi yePE inogonawo kubatanidzwa kune mamwe mapaipi emhando yepamusoro kuburikidza nekushandisa ma "compression fittings", ma "flanges", kana mamwe marudzi akakodzera e "transition fittings" akagadzirwa.
Chipo chega chega chine zvakanakira uye zvipingamupinyi zvakasiyana-siyana zvemamiriro ega ega ekubatana nemushandisi. Kutaurirana nevagadziri vakasiyana-siyana kunokurudzirwa kuti uwane gwara rekushandisa nemasitayera akakodzera ekubatana sezvakatsanangurwa mugwaro iri sezvinotevera.
Nzira dzekubatanidza
Kune mhando dzakasiyana-siyana dzemajoini ekubatanidza kupisa anoshandiswa pari zvino muindasitiri iyi: Butt, Saddle, uye Socket Fusion. Pamusoro pezvo, majoini ekubatanidza electrofusion (EF) anowanikwa neEF couplers dzakakosha uye saddle fittings.
Nheyo yekubatanidza kupisa ndeyekupisa nzvimbo mbiri kusvika patembiricha yakatarwa, wobva wadzibatanidza pamwe chete nekushandisa simba rakakwana. Simba iri rinoita kuti zvinhu zvakanyunguduka zviyerere uye zvisanganiswe, zvichikonzera kusanganiswa. Kana zvikabatanidzwa zvichienderana nemaitiro emugadziri wepombi uye/kana kuti akakodzera, nzvimbo yekubatana inova yakasimba se kana kuti yakasimba kupfuura, pombi pachayo muhunhu hwekudhonza uye hwekumanikidza uye majoini akabatanidzwa zvakanaka haadonhedze mvura zvachose. Kana joini yangotonhora kusvika patembiricha iri pedyo, inenge yagadzirira kubatwa. Zvikamu zvinotevera zvechitsauko chino zvinopa gwara rehurongwa hweimwe neimwe yenzira idzi dzekubatanidza.

3. Migumo yemapaipi ePE inodziiswa nekubatanidza pasi pekumanikidzwa (P1) paplate yeheater. Maplate eheater anofanira kunge akachena uye asina kusvibiswa, uye akachengetedzwa mukati mekupisa kwepamusoro (210±5 ℃C yePE80, 225±5 C yePE100). Kubatanidza kunochengetwa kusvika kupisa kwakaenzana kwagadzirwa kutenderedza magumo epaipi, uye kumanikidzwa kwekubatanidza kunoderedzwa kusvika pamutengo wakaderera P2(P2=Pd). Kubatana kunochengetwa kusvika "Step-absorption Step" yapera.
Kusanganiswa kweMatako
Kubatanidza mabutt ndiyo nzira inonyanya kushandiswa yekubatanidza hurefu hwemapaipi ePE nemapombi kune PE fittings, izvo zvinoitwa nekupisa magumo emabutt epombi sezvakaratidzwa muMufananidzo. Iyi nzira inoita kuti pave nekubatana kunogara kwenguva refu, kwakachipa uye kunoshanda zvakanaka. Mabutt fusion emhando yepamusoro anogadzirwa nevashandisi vakadzidziswa vari mumamiriro akanaka.
Kubatanidza mabutt kunowanzo shandiswa pamapaipi ePE ari pakati pe63 mm kusvika 1600 mm pakubatanidza mapaipi, mafittings uye ekupedzisira. Kubatanidza mabutt kunopa kubatana kwakafanana kune hunhu hwakafanana nehwepaipi nezvinhu zvemafittings, uye kugona kudzivirira mitoro yakareba.
4. Migumo yepombi inodziya inobva yadzoserwa shure uye ndiro yeheater inobviswa nekukurumidza sezvinobvira (t3: hapana kumanikidzwa kwekubata).
5. Migumo yemapaipi ePE anopisa inobva yaunganidzwa pamwe chete yomanikidzwa zvakaenzana kusvika pakumanikidzwa kwewelding (P4=P1). Kumanikidzwa uku kunochengetwa kwenguva yakati kuti maitiro ewelding aitike, uye fused joint itonhore kusvika pakupisa kwemhepo uye nokudaro iwane simba rakazara remajoini. (t4+t5). Munguva iyi yekutonhora majoini anofanira kuramba asina kukanganiswa uye ari pasi pekumanikidzwa. Hapana mamiriro ezvinhu anofanira kupfapfaidzwa nemvura inotonhora majoini. Musanganiswa wenguva, tembiricha, uye kumanikidzwa kunofanira kushandiswa zvinoenderana nePE material grade, dhayamita uye ukobvu hwemadziro emapombi, uye rudzi nemuenzaniso wemuchina wefusion uri kushandiswa.

Kusanganiswa kweSocket
Kune mapaipi ePE nemidziyo ine dhayamita diki (kubva pa20mm kusvika 63mm), kusanganisa masokisi inzira iri nyore. Nzira iyi inosanganisira kupisa panguva imwe chete pamusoro pepombi nepamusoro pesokisi kusvika zvinhu zvasvika pakupisa kwefusion, kuongorora patani yekunyunguduka, kuisa magumo epombi musokisi, uye kuibata panzvimbo yayo kusvika joini yatonhora. Mufananidzo uri pazasi unoratidza joini yekubatanidza masokisi isingawanzoitiki.
Zvinhu zvinodziya zvinoputirwa nePTFE, uye zvinofanirwa kucheneswa uye zvisina kusvibiswa nguva dzese. Zvishandiso zvinodziya zvinofanirwa kugadziriswa uye kugadziriswa kuti tembiricha yepamusoro igare yakadzikama kubva pa240 C kusvika 260 ℃, zvinoenderana nedhayamita yepombi. Kubatanidza kwese kunofanirwa kuitwa pasi pechifukidziro kudzivirira kusvibiswa kwemajoini kubva kuguruva, tsvina, kana hunyoro.
Maitiro ekubatanidza socket
1. Cheka mapaipi, chenesa chikamu che spigot nejira rakachena uye doro risingaisi doro kusvika pakadzika kwesoketi. Maka kureba kwesoketi. Chenesa mukati mechikamu chesoketi.

Kubatana Kwemakanika
Sezvineiwo nenzira dzekubatanidza kupisa, kune mhando dzakawanda dzemaitiro ekubatanidza michina, dzakadai se: flange connection, PE-steel transition part...
Kusanganiswa kweElectromagnetic
Mukubatanidza kupisa kwakajairika, chishandiso chekudziisa chinoshandiswa kudziisa pombi nenzvimbo dzekuisa. Joint yemagetsi inodziiswa mukati, kungave neconductor panzvimbo inopindirana joint kana, sezvakaita mune imwe dhizaini, neconductive polymer. Kupisa kunogadzirwa sezvo magetsi emagetsi akaiswa kune chinhu chinofambisa magetsi chiri mu fitting. Mufananidzo 8.2.3.A unoratidza joint yemagetsi yakajairika. Kubatana kwepombi yePE nepombi kunoitwa uchishandisa electrofusion process kunoda kushandiswa kwe electrofusion couplings. Musiyano mukuru pakati pe conventional heat fusion ne electrofusion inzira inoshandiswa kupisa.
Maitiro eElectrofusion
1. Cheka mapaipi ane sikweya, womaka mapaipi acho nehurefu hwakaenzana nehupamhi hwesoketi.
2. Konera chikamu chakaiswa chiratidzo chepombi yesimbi kuti ubvise zvidimbu zvese zvePE zvakasanganiswa kusvika pakadzika kweinenge 0.3mm. Shandisa chikwenya chemaoko, kana chikwenya chepeel chinotenderera kubvisa zvidimbu zvePE. Usashandise sandpaper.
