Znanje o namestitvi cevi PPR
Metode cevovodne povezave vključujejo varjenje, vročo taljenje in navojno povezavo. PPR cev vroče topljenje povezava je najbolj zanesljiv, enostaven za delovanje, dobro zračno tesnost, visoka moč vmesnika. Cevni priključek sprejme ročno varilno napravo za vročo topljenje priključka. Prah in tujo snov je treba pred priklopom odstraniti iz cevi in pribora. Ko je rdeča luč stroja prižgana in stabilna, poravnajte cevovod (del), ki naj bo priključen DN< 50="" hot-melt="" depth="" of="" 1-2mm,="" dn="">< 110="" hot-melt="" depth="" of="" 2-4mm. when="" connecting,="" insert="" the="" tube="" end="" into="" the="" heating="" sleeve="" without="" rotation="" to="" reach="" the="" predetermined="" depth. at="" the="" same="" time,="" push="" the="" pipe="" fittings="" to="" the="" heating="" head="" without="" rotation="" for="" heating.="" after="" reaching="" the="" heating="" time,="" immediately="" remove="" the="" pipe="" and="" fittings="" from="" the="" heating="" sleeve="" and="" the="" heating="" head="" at="" the="" same="" time,="" and="" insert="" the="" pipe="" and="" fittings="" into="" the="" required="" depth="" rapidly="" without="" rotation="" and="" with="" uniform="" force="" to="" make="" the="" joint="" form="" a="" uniform="" flange. within="" the="" specified="" heating="" time,="" the="" welded="" joint="" can="" be="" corrected,="" but="" rotation="" is="" strictly="" prohibited. when="" heating="" pipes="" and="" fittings,="" prevent="" excessive="" heating="" to="" thin="" the="" thickness. the="" pipe="" is="" deformed="" in="" the="" pipe="" fittings. do="" not="" rotate="" during="" hot="" melt="" intubation="" and="" calibration. there="" shall="" be="" no="" open="" fire="" on="" the="" operation="" site,="" and="" it="" is="" strictly="" prohibited="" to="" dry="" and="" bend="" the="" pipe="" with="" open="" fire. the="" heated="" pipe="" and="" fittings="" should="" be="" aligned="" vertically="" with="" light="" force="" to="" prevent="" bending="" of="" the="" elbow. after="" connection,="" the="" pipe="" and="" pipe="" fittings="" must="" be="" held="" tightly="" for="" enough="" cooling="" time,="" and="" can="" be="" released="" after="" cooling="" to="" a="" certain="" extent. when="" pp-r="" pipe="" is="" connected="" with="" metal="" pipe="" fitting,="" pp-r="" pipe="" with="" metal="" insert="" should="" be="" used="" as="" transition,="" the="" pipe="" fitting="" is="" connected="" with="" pp-r="" pipe="" by="" hot="" melt="" socket,="" and="" when="" connected="" with="" metal="" pipe="" fitting="" or="" hardware="" fittings="" of="" sanitary="" ware,="" thread="" connection="" is="" used,="" and="" polypropylene="" raw="" material="" belt="" should="" be="" used="" as="" sealing="">Če je bazen za mop priključen na pipo, namestite notranji komolec (navoj) na koncu PPR cevi na cev.V postopku montaže cevovoda ne uporabljajte preveč sile, da ne poškodujete vijačnih sponke in povzročite uhajanje pri priključku. Rezanje cevi lahko režemo tudi s posebnimi škarjami za cevi: bajonet škarij za cevi je treba prilagoditi tako, da je skladen s premerom cevi, ki jo je treba rezati, in silo je treba enotno uporabiti, ko je cev odrezana. Po razrezu je treba zlom zaokrožiti s podporno kroglo. Ko je cev zlomljena, je treba odsek pravokotno na os cevi brez burrs.
