Znanje o instalaciji PPR cijevi
Metode spajanja na cjevovod uključuju zavarivanje, spajanje vrućim taljenjem i navojno spajanje. PPR cevni priključak za toplo topljenje je najpouzdaniji, jednostavan za rukovanje, dobra nepropusnost vazduha, visoka čvrstoća interfejsa. Priključak cijevi koristi ručni uređaj za zavarivanje za spajanje vruće taline. Prije spajanja potrebno je ukloniti prašinu i strane tvari s cijevi i pribora. Kada je crveno svjetlo na stroju upaljeno i stabilno, poravnajte cjevovod (dio) koji treba spojiti 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="">Ako je bazen za mop spojen na slavinu, ugradite unutrašnje koleno (navojno) na kraju PPR cijevi na njega.Prilikom ugradnje cjevovoda nemojte primjenjivati preveliku silu kako ne biste oštetili navojne spojnice i izazvali curenje na spoju. Rezanje cijevi se također može rezati posebnim makazama za cijevi: bajonet makaza za cijevi treba podesiti tako da odgovara prečniku cijevi koju treba rezati, a sila treba ravnomjerno primijeniti kada se cijev odsiječe. Nakon rezanja, lom treba zaokružiti nosećim zaobljencem. Kada je cijev slomljena, presjek treba biti okomit na os cijevi bez ivica.
