Welding maitiro ePE mvura yekupa pombi

PE mvura yekupapipeline welding process matanho:

1) Zvinoenderana neyakaiswa welding yePE yemvura pombi, sarudza welding mold uye wobatidza kupisa kwemagetsi:

2) Zvinoenderana neshanduko yetembiricha yemwaka, tembiricha yekudziya inochinja kana kudzikira (± 10 ℃) kubva payakajairwa tembiricha, tembiricha yakajairika i20 ℃.

3) Cheka chiso chekupedzisira chePE mvura yepombi kuitira kuti chiso chayo chekupedzisira chienderane kune axis;

4) Iyo pombi yekupa mvura uye zvigadziriso zvepombi zvinofanirwa kuchengetedza kupindira kwakakodzera, uye chikamu chakawandisa chinofanira kubviswa nekucheka maturusi.

5) Bvisa tsvina nekumwe kusvibiswa kubva kunze uye mukati mukati menzvimbo dzekuputira dzepombi dzemvura uye fittings.

6) Muchigadziro chekugadzira, kudzika kwekupinza kwepombi yemvura hakufaniri kunge kwakadzika, izvo zvichaita kuti kuvharika kwepombi yemvura, isina kukodzera kunyura, diving welding inogona kunge isina kusimba.

7) Isai iyo welded PE yekupa mvura pombi uye pombi inokodzera mukudziya mold panguva imwe chete.Kana nguva yekupisa yasvika, dhonza kunze nekukurumidza uye uise iyo welded yepombi yekugovera mvura mupombi inokodzera neuniform pressure (kazhinji 2-3 Mpa).Sunda kusvika iyo yakadzika yakadzama yaiswa mupombi, ichibvumira diki diki rekugadzirisa munguva pfupi pfupi.

8) Zvinoenderana nezvakatsanangurwa zvePE yemvura pombi yemvura, chengetedza mamiriro ekupisa kusvika panguva yekutonhora, kazhinji kubva pamaminitsi makumi matatu kusvika makumi mashanu.
