Inkqubo yokuwelda yombhobho wonikezelo lwamanzi we-PE

Unikezelo lwamanzi lwe-PEAmanyathelo enkqubo yokudibanisa umbhobho:

1) Ngokweenkcukacha ze-welding zombhobho wokuhambisa amanzi we-PE, khetha i-welding mold kwaye uvule ukufudumeza kombane:

2) Ngokotshintsho lobushushu bexesha lonyaka, iqondo lobushushu liyaguquguquka okanye liyehla (± 10 ℃) ukusuka kwiqondo lobushushu lokuqala, umgangatho wobushushu ngu-20 ℃

3) Nciphisa ubuso bokuphela kombhobho wokuhambisa amanzi we-PE ukuze ubuso bayo bokugqibela bube yi-perpendicular kwi-axis;

4) Umbhobho wonikezelo lwamanzi kunye nokufakelwa kombhobho kufuneka kugcine ukuphazamiseka okufanelekileyo, kwaye inxalenye engaphezulu kufuneka isuswe ngezixhobo zokusika.

5) Susa ukungcola kunye nezinye izinto ezingcolileyo kwiindawo zangaphandle kunye zangaphakathi zeendawo ze-welding zemibhobho yokuhambisa amanzi kunye nokufakelwa.

6) Kwinkqubo ye-welding, ubunzulu bokufakwa kombhobho wokuhambisa amanzi akufanele bunzulu kakhulu, okuya kubangela ukuvaleka kombhobho wokuhambisa amanzi, engafanelekanga ukuntywila, i-diving welding ayinako iqinile.

I-7) Faka umbhobho wokuhambisa amanzi we-PE odibeneyo kunye nokufakwa kombhobho kwi-mold yokufudumala ngexesha elifanayo.Xa ixesha lokufudumala lifikeleleke, khupha ngokukhawuleza kwaye ufake isiphelo esidibeneyo sombhobho wokuhambisa amanzi kumbhobho ohambelana noxinzelelo olufanayo (ngokuqhelekileyo i-2-3 Mpa).Pusha kude kube ubunzulu obuphawulweyo bufakwe kumbhobho, ukuvumela uluhlu oluncinci lohlengahlengiso ngexesha elifutshane kakhulu.

8) Ngokweenkcukacha zombhobho wokuhambisa amanzi we-PE, gcina i-welding state kwixesha lokupholisa, ngokubanzi ukusuka kwimizuzu engama-30 ukuya kwimizuzu engama-50.
