2. Tubing yemutsetse wemvura:

Muhurongwa hwekugovera mvura, kupihwa mvura yakachena uye kwakachengeteka kwakakosha.Spiral welded kabhoni simbi pombi yakaratidza kuva sarudzo yakavimbika yemapombi emvura nekuda kweiyo isingadziviriri zvinhu.Nzvimbo yakatsetseka yepombi idzi inoderedza kukweshana, zvichiita kuti mvura irambe ichiyerera uye kuderedza mhirizhonga.Pamusoro pezvo, simba rekuzvarwa uye kusimba kunovimbisa kuchengetedzwa kubva pakudonha, kuputsika, uye kutadza kwechimiro, kuve nechokwadi chekuenderera, yakavimbika mvura.

3. Metal pombi welding:

Indasitiri yewelding inotsamira zvakanyanya pane spiral welded kabhoni simbi pombi kune akasiyana maapplication.Iyo yakasarudzika simba uye kuchinjika kwepombi idzi dzinoita kuti dzive dzakanakira simbi pombi welding.Kungave kuvaka matangi makuru ekuchengetera, mapaipi ekutakura oiri negasi, kana zvimiro munzvimbo dzemaindasitiri, spiral welded kabhoni simbi mapaipi anoita basa rakakosha.Kufanana kwemajoini akashongedzwa kunovimbisa kuvimbika uye kuchengetedzwa kwechimiro, kuderedza kudiwa kwekugara uchigadzirisa kana kugadzirisa.

4. Zvakanakira uye zvakanakira:

4.1 Inodhura-inoshanda mhinduro: Spiral welded carbon steel pombi inopa inodhura-inoshanda mhinduro yepombi yemvura uye simbi pombi welding.Kugara kwavo uye kusagadzikana kwekuora kunovimbisa hupenyu hurefu hwesevhisi, nokudaro kuderedza kutsiva uye kugadzirisa mari.

4.2 Zviri nyore kuisa: Iyo spiral welding tekinoroji inoshandiswa mukugadzira nzira inogona kugadzira mapaipi akareba uye anoenderera, achideredza kudiwa kweanowanzo majoini.Iyi dhizaini yakagadziridzwa inorerutsa maitiro ekuisa, kuchengetedza nguva uye kushanda nesimba.

4.3 Versatility: Spiral welded kabhoni simbi mapaipi anowanikwa mune akasiyana madhayamita uye ukobvu, achiabvumira kuti agadziriswe kune akasiyana maapplication.Ivo vanogona kugadzirwa kuti vasangane nezvinodiwa zveprojekiti, kuchinjika kune akasiyana emvura, kumanikidza uye tembiricha.

4.4 Kuchengetedzwa kwezvakatipoteredza: Carbon simbi chinhu chinodzokororwa chinobatsira mukuchengetedzeka kwezvakatipoteredza.Spiral welded kabhoni simbi mapaipi anogona kudzokororwa uye kushandiswazve, kuderedza marara uye kudzivirira zviwanikwa.

Mukupedzisa:

Iko kugona uye zvakanakira spiral welded kabhoni simbi mapaipi mumvura pombi uyesimbi pombi weldinghaigoni kurerutswa.Iyo inoshanda uye yakavimbika kuendeswa kwemvura uye zvinwiwa zvemumaindasitiri zvinotsamira zvakanyanya pakusimba kwavo, kusagadzikana kwekuora uye kureruka kwekuisa.Sezvo kudiwa kwezvivakwa zvakasimba uye zvisingadhuri zvichiramba zvichikwira, spiral welded carbon steel pombi icharamba iri chikamu chakakosha mukuona kushanda zvakanaka kwemasystem emvura nemaindasitiri maindasitiri pasi rese.
