Product Description:

Spiral welded simbi mapaipi, nedhizaini yavo, inopa akati wandei akasiyana mabhenefiti pane akajairwa pombi masisitimu.Yayo yakasiyana-siyana yekugadzira maitiro inovimbisa hutsika hunoenderana nehurefu hwayo hwose, huchiita kuti ive yakanyanya kupikisa mukati uye kunze kwekumanikidzwa.Uku kusimba kunoita spiral welded pombi yakanakira oiri uye gasi kutapurirana maapplication uko kuchengetedzeka uye kuvimbika kwakakosha.

Iyo spiral welding tekinoroji inoshandiswa mukugadzirwa kwayo inopa kuchinjika kukuru uye kuchinjika, ichibvumira pombi kuti imirisane nemamiriro akanyanya akadai sekupisa kwakanyanya, kudzvanywa kwakasiyana uye njodzi dzinongoitika dzoga.Pamusoro pezvo, iyi dhizaini yekuvandudza inokwidziridza ngura uye kupfeka kuramba, zvichibatsira kuwedzera hupenyu hwebasa uye kuderedza mari yekugadzirisa.
