Izinyathelo zokuthi kuxhunywe ukuncibilika kukagesi kwepayipi le-PE

Ukuxhumana kwe-electrowelding yeIpayipi le-PEkuqala usetha ipayipi electrowelding phezulu kwepayipi, bese usebenzisa umshini wokushisela okhethekile ukuze unike amandla ukufakwa kwepayipi le-electrowelding ngokusho kwemingcele ecacisiwe (isikhathi, i-voltage, njll.).Ingxenye yangaphakathi yepayipi le-electromelting elifakwe ngocingo lokushisisa kagesi kanye nendawo yangaphandle yokugcina ishubhu iyancibilika, futhi ipayipi nokufaka ipayipi kuhlanganiswe ndawonye ngemva kokupholisa.Ngakho-ke yini okufanele siyinake lapho sixhuma?

1. Imishini yokuxhuma i-welding kanye nokufakwa kwe-welding kufanele ihlangabezane namazinga.Lapho uxhuma, i-voltage kanye nesikhathi sokushisa sokunikezwa kwamandla kuzohambisana nezidingo zomkhiqizi wokufakwa kwamapayipi wokushisela, futhi izinyathelo zokuvikela ugesi ezihambisanayo zizonikezwa ngokuya nge-voltage namandla amanje asetshenzisiwe kanye nezici zokunikezwa kwamandla.

2. Uma ipayipi le-PE selipholile ukuze kuxhunywe i-electromelting, amandla angaphandle awakwazi ukusetshenziswa kuzixhumi noma izixhumi.

3. Ipayipi le-PE elixhunywe isokhethi likagesi lokushisela kufanele lihlangabezane nalezi zidingo ezilandelayo:

① Ukuphela kokuxhuma kwesokhethi yokushisela kufanele kusikwe kuqonde, futhi ukungcola okusemapayipini nasezisekelini kufanele kusulwe ngendwangu kakotini ehlanzekile, futhi ukujula kokufakwayo kufanele kumakwe, futhi isikhumba kufanele sikhishwe ngokungahleliwe.

② Ngaphambi kokuba isokhethi yokushisela ixhunywe, izixhumi ezimbili ezihambisanayo kufanele ziqondaniswe ukuze ipayipi le-PE libe ku-eksisi efanayo.
