Zvakanakira Kushandisa SPIRALLY WELDED STEEL PIPES ASTM A252
Imwe yemabhenefiti makuru ekushandisa ASTM A252 spiral welded simbi pombi isimba rayo rakakura uye kusimba. Mapombi aya anogona kumirisana nekumanikidzwa kukuru uye mitoro inorema, ichiita kuti ive yakakodzera kufambiswa kwemafuta negesi, kufambisa kwemvura uye zvimiro zvekushandisa. Iyo spiral welding process inoshandiswa mukugadzira inovimbisa yakasimba uye kunyange chisungo, ichibvumira pombi kuti imirire nharaunda dzakaomarara.

Product Analysis
Simbi haifaniri kunge iine 0.050% phosphorous.
Misiyano Inobvumirwa Muhuremu Uye Zviyero
Hurefu hwega hwega hwemurwi wepombi huchayerwa zvakasiyana uye huremu hwahwo hahuzosiyana kupfuura 15% pamusoro kana 5% pasi pehuremu hwayo hwekufungidzira, huchiverengerwa uchishandisa kureba uye huremu hwayo pakureba kweyuniti.
Iyo dhayamita yekunze haifanire kusiyana kupfuura ± 1% kubva kune yakatsanangurwa yekunze dhayamita
Ukobvu hwemadziro chero nguva haufanire kupfuura 12.5% pasi peiyo yakataurwa madziro ukobvu
Urefu
Single random urefu: 16 kusvika 25ft (4.88 kusvika 7.62m)
Hurefu hwakapetwa kaviri: pamusoro pe25ft kusvika 35ft (7.62 kusvika 10.67m)
Hurefu hwakafanana: musiyano unobvumidzwa ±1in
Pamusoro pesimba,spilly welded simbi mapaipi ASTM A252inopa yakanakisa corrosion resistance. Izvi zvinonyanya kukosha kune mapaipi akafumurwa kune hutsinye hwemamiriro ekunze kana zvinhu zvinoparadza. Iyo inodzivirira yekudzivirira pamapombi aya inowedzera kuwedzera kusakara kwavo, kuve nechokwadi chehupenyu hurefu hwesevhisi uye kuderera kwemitengo yekugadzirisa.
Uyezve, spirally welded steel pombi ASTM A252 inozivikanwa nekusiyana-siyana kwayo uye nyore kuisa. Dhizaini yavo inochinjika inogona kugadziridzwa zviri nyore kuti isangane nezvinodiwa zveprojekiti, nepo huremu hwavo hunoita kuti kubata uye kufambisa kuve nyore. Izvi zvinovaita sarudzo inodhura kune dzakasiyana siyana dzekushandisa, sezvo dzinogona kuiswa nekukurumidza uye zvinobudirira, kuderedza basa uye nguva yekuvaka.
Imwe mukana wekushandisa ASTM A252 spiral welded simbi pombi ndiko kuchengetedza kwayo kwezvakatipoteredza. Yakagadzirwa kubva kuzvinhu zvinodzokororwa, mapaipi aya anogona kushandiswa zvakare kana kudhindwa pakupera kwehupenyu hwawo hunobatsira, kuderedza kukanganiswa kwemamiriro ekunze kwekuvaka nekugadzirisa pombi. Pamusoro pezvo, hupenyu hwayo hurefu uye zvakaderera zvekugadzirisa zvinodiwa zvinopa kune yakagadzikana uye ine hushamwari zvivakwa.
Mukupedzisa, spilly welded simbi pombi ASTM A252 ine akatevedzana mabhenefiti anoita kuti ive yekutanga sarudzo yekuvaka pombi. Kusimba kwavo kwepamusoro, kusimba, kuramba kwecorrosion, kuita zvakasiyana-siyana uye kuchengetedza kwezvakatipoteredza kunoita kuti ive yakakodzera kune akasiyana maapplication mumaindasitiri akasiyana. Nekusarudza mapombi aya, vanogadzira chirongwa vanogona kuve nechokwadi chekuvimbika uye chinogara kwenguva refu yepombi system inosangana nemhando yepamusoro uye maitiro ekuita.
