SSAW Simbi Pipe For Underground Water Line
Kutangwa kwe revolutionary spiral undermerged arc welded steelpombi yemitsara yemvura yepasi pevhu
Cangzhou Spiral Steel Pipe Group Co., Ltd. yakaparura pombi yayo yesimbi inoputika, inotenderera musono pombi yesimbi inozoshandura indasitiri yepombi yepasi.Iyi pombi inoshandura mutambo mumusika wemanisiparati wemvura uye tsvina yekuendesa mvura nekuda kwemhando yepamusoro uye kushanda kwepamusoro.

SSAW simbi mapaipianogadzirwa nema stripe simbi coils semidziyo yakabikwa, anoburitswa pakupisa nguva dzose, uye akasungwa neatomatiki kaviri-waya-yakapetwa-mativi akanyudzwa arc welding process.Iyi tekinoroji yekugadzira tekinoroji inovimbisa iwo epamusoro mazinga ekurongeka uye kusimba, zvichiita kuti mapaipi edu akwane kune yepasi pemvura mitsara yekushandisa.
Moyo uyuspiral simbi pombidhizaini yaro yakasarudzika.Simbi yemutsetse inopinzwa mupombi yakasungwa uye zvishoma nezvishoma inopetwa nema roller akawanda kuti iite denderedzwa chubhu isina chinhu ine gwanza rekuvhura.Iyo ine kugona kugadzirisa kudzikisa huwandu hweiyo extrusion roller, uye iyo weld gap inogona kudzorwa pakati pe1-3mm kuve nechokwadi chekubatana uye kwakasimba.Pamusoro pezvo, migumo yese yejoini yakashongedzerwa yakanyungudika, ichipa kupera kwakakwana.
Mapaipi esimbi eSSAW ane maitiro akati wandei anoasiyanisa kubva kune echinyakare simbi pombi.Chimiro chayo chinotenderera chine simba rakanakisa uye kuramba kune masimba ekunze, kuve nechokwadi chekuchengetedza uye kuvimbika kweiyo nzira yekuendesa mvura.Pamusoro pezvo, iyo yemhando yepamusoro-welding process inovimbisa kuti majoini haabvisike uye anodzivirira kubuda kwemvura kana kusvibiswa.Nekuvaka kwayo kwakasimba uye kubatanidza kwakachengeteka, pombi iyi inovimbisa kushanda kwenguva refu uye inoderedza zvinodiwa zvekugadzirisa, zvichiita kuti ive mhinduro inodhura kune chero chirongwa chemvura yepasi.

Ichi chigadzirwa chakasarudzika chakagadzirirwa kusangana nezvinodiwa zvakasiyana zveindasitiri.Kunyangwe kuvaka masisitimu emvura uye masisitimu ekufambisa etsvina kana kutakura gasi rechisikigo neoiri pamusoro pemadaro marefu, spiral yakanyura arc welded pombi ndiyo sarudzo yekutanga.Hurukuro hwayo hunosvika kune masisitimu epombi mirwi, ichipa kugadzikana kusingaenzaniswi uye kutakura mutoro.Nekusimba kwavo kwepamusoro uye kuvimbika, mapaipi edu anopfuura zvese zvinotarisirwa maererano nekuita uye hupenyu hurefu.
PaCangzhou Spiral Steel Pipe Group Co., Ltd., kuzvipira kwedu kuita zvakanaka hakuzununguki.Nemakore eruzivo rweindasitiri uye hunyanzvi, isu tinodada nekuendesa zvigadzirwa zvemhando yepamusoro zvinosangana nemhando yepamusoro.Nzvimbo dzedu dzemazuva ano dzekugadzira uye maitiro akasimba ekudzora emhando inovimbisa kuti yese spiral yakanyura arc welded simbi pombi inosiya fekitori ndeyemhando yepamusoro.
Muchidimbu, shanduko inotenderera yakanyura arc welded simbi pombi inoshandura indasitiri yepombi yemvura yepasi pevhu.Inosanganisira kuvakwa kwepamusoro-soro, majoini-asingabvumire kubuda uye simba repamusoro, pombi iyi ndiyo sarudzo yekupedzisira kune chero chirongwa chekufambisa mvura.Tenda kuti Cangzhou Spiral Steel Pipe Group Co., Ltd. inogona kukupa mhinduro yakanakisa yekuzadzisa zvaunoda.Sangana neramangwana remvura yepasi pombi masisitimu ane SSAW simbi pombi.
