Spiral Welded Mapaipi ePasi pevhu Gesi Mapaipi EN10219
Yeduspiral welded pombindiyo mhinduro yakanakira mapurojekiti uko kuramba kwecorrosion uye kurongeka kwechimiro kwakakosha. Iyo yakasarudzika spiral welding process haisi kungowedzera simba repombi, asi inopawo nzvimbo isina musono, inoderedza njodzi yekudonha uye kutadza. Izvi zvinovaita kuti vanyatsokodzera nzvimbo dzakaomarara dzinowanzo sangana mumashandisirwo epasi pevhu.
Iyo EN10219 yakajairwa inova nechokwadi chekuti mapaipi edu anogadzirwa nemazvo uye nemhando, kuve nechokwadi kuti anogona kushingirira uye nematambudziko ekufambisa gasi rechisikigo. Yakatarisana nekusimba uye kuvimbika, yedu spiral welded pombi dzakagadzirirwa kupa kushanda kwenguva refu, kuderedza kudiwa kwekugarogadzirisa uye kutsiva.

Pamusoro pekuvaka kwadzo kwakashata, mapaipi aya haaremekedzi uye ari nyore kubata, zvichiita kuti kuisirwa kushande uye kudhure. Kunyangwe iwe uri kuita purojekiti yepombi nyowani kana kukwidziridza sisitimu iripo, mapaipi edu espiral welded anopa musanganiswa wakakwana wesimba, kuchinjika, uye kutevedzera indasitiri zviyero.
Sarudza yedu spiral welded mapaipi kune ako epasi pevhu pombi pombi uye uwane rugare rwepfungwa runouya nekushandisa zvigadzirwa zvinosangana.EN10219mitemo. Vimba kuzvipira kwedu kune mhando uye kuita kuti ive nechokwadi chekuchengetedza uye kugona kwegasi rako zvigadzirwa.
