Munyika inogara ichishanduka yekuvaka nehuinjiniya, kudiwa kwezvinhu zvemhando yepamusoro zvinovimbisa kuchengeteka, kusimba, uye kushanda nesimba kwakakosha.S235 J0 Spiral Steel Pipechigadzirwa cheshanduko chakagadzirirwa kusangana neyakaomarara zviyero zvemazuva ano zvimiro zvekushandisa. Iyi mhinduro itsva inopfuura kungova pombi; icho chipupuriro kune enjiniya yepamusoro uye maitiro ekugadzira anoisa pamberi pesimba uye kuvimbika.
S235 J0 spiral simbi mapaipi anogadzirwa zvinoenderana neEuropean zviyero izvo zvinotsanangura tekinoroji yekuendesa mamiriro einotonhora-yakaumbwa welded structural hollow zvikamu. Izvi zvinoreva kuti pombi imwe neimwe inogadzirwa pachishandiswa kutonhora-kuumba maitiro, kuve nechokwadi kuti kutendeseka kwechimiro kunochengetedzwa pasina kudiwa kwekutevera kurapwa kwekupisa. Iyo yekupedzisira chigadzirwa ine yakanakisa mechaniki zvivakwa, ichiita kuti ive yakanakira akasiyana ekushandisa mukuvaka, zvivakwa uye maindasitiri mapurojekiti.

Hydrostatic Test
Hurefu hwega hwega hwepombi huchaedzwa nemugadziri kune hydrostatic pressure iyo inoburitsa mumadziro epombi kushushikana kusingasviki 60% yeiyo yakataurwa kushomeka kwegoho pakupisa kwekamuri. Kudzvanywa kunozotemwa neinotevera equation:
P=2St/D
Kusiyana Kunobvumirwa Muhuremu uye Zviyero
Hurefu hwega hwega hwepombi huchayerwa hwakaparadzana uye huremu hwayo hahuzosiyane kupfuura 10% pamusoro kana 5.5% pasi pehuremu hwayo hwekufungidzira, huchiverengerwa pachishandiswa hurefu hwayo nehuremu hwayo pakureba kweyuniti.
Iyo dhayamita yekunze haifanire kusiyana kupfuura ± 1% kubva kune yakatsanangurwa yekunze dhayamita

Imwe yeakamira maficha eS235 J0 Spiral Steel Tube ndeyekuita kwayo kwakasiyana. Inowanikwa mukutenderera, mativi uye rectangular mafomu, chigadzirwa chinogona kugadzirwa kuti chienderane nezvinodiwa zvechero chirongwa. Kunyangwe iwe uri kuvaka dhizaini yakasimba yechivakwa chekutengesa, kugadzira dhizaini yakaoma yekuvaka, kana kugadzira zvakakosha senge mabhiriji nematani, S235 J0 Spiral Steel Tube inopa kuchinjika uye simba rinodiwa kuti uone chiono chako.
Iyo S235 inodudza inoratidza kuti chubhu inogadzirwa kubva musimbi yekugadzira ine yakanakisa weldability uye machinability. Izvi zvinonyanya kukosha kumapurojekiti anoda kunyatsogadzirwa uye kubatanidza. Iyo J0 suffix inoratidza kuti zvinhu zvinogona kumira kutonhora kwakadzika, zvichiita kuti zvikwanise kushandiswa munzvimbo dzakaoma umo kushanduka kwekushisa kunogona kuunza njodzi kukuvimbika kwechimiro. Uku kusanganiswa kwezvivakwa kunovimbisa kuti S235 J0 spiral steel chubhu haisi kungovimbika chete, asiwo inokwanisa kutsungirira huwandu hwakawanda hwemamiriro ekunze.
Uye zvakare, iyo inotonhora-yakaumbwa hunhu hweS235 J0 spiral simbi pombi inoipa iyo yakanakisa kupedzisa kwepamusoro uye kurongeka kwechokwadi. Izvi zvinoreva kuti pombi inogona kubatanidzwa nyore nyore muhurongwa huripo pasina kuchinja kukuru. Iyo yakatsetseka yepamusoro inosimudzirawo aesthetics yechigadzirwa chekupedzisira, ichiita sarudzo yepamusoro yevagadziri uye vagadziri vanokoshesa mashandiro uye maitiro ekuona.
Pamusoro pezvakanakira zvehunyanzvi, S235 J0 spiral simbi pombi zvakare isarudzo ine hushamwari. Iyo nzira yekugadzira inoderedza marara uye kushandiswa kwesimba, zvinoenderana nekukura kwemaitiro ekusimudzira muindasitiri yekuvaka. Nekusarudza chigadzirwa ichi, hausi kungoisa mari mumhando, asi zvakare uchipa kune ramangwana rakasvibira.
Zvese mune zvese, S235 J0 Spiral Steel Tube ndeye yekucheka-kumucheto mhinduro inonyatso kusanganisa simba, kuita zvakasiyana uye kusimba. Kunyangwe iwe uri kutanga chirongwa chitsva chekuvaka kana kutsvaga kuwedzera chimiro chiripo, chigadzirwa ichi chakagadzirirwa kusangana uye kudarika zvaunotarisira. Kutevedzera zviyero zveEurope uye neakanakisa maitiro ekuita, S235 J0 Spiral Steel Tube ndiyo yakanakira mainjiniya, vagadziri vezvivakwa uye vavaki vanoda zvakanakisa muzvigadzirwa zvezvimiro. Gamuchira ramangwana rekuvaka neS235 J0 Spiral Steel Tube - musanganiswa wekuvandudza uye kuvimbika.
