Spiral Welded Simbi Pipe Kune Risingaenzaniswi Simba Uye Kushanda ASTM A252
suma:
Kana zvasvika pakuvandudzwa kwezvivakwa, masisitimu epombi chinhu chakakosha chinoita basa rakakosha mumaindasitiri akasiyana.Kushandisa zvinhu zvakakodzera uye hunyanzvi mukuvakwa kwepombi kunovimbisa kusimba, simba uye kuvimbika, uyespiral welded simbi pombi ASTM A252iri pamberi pakufambira mberi kwemichina iyi.Mune ino blog, isu tichatarisisa kune yakasarudzika hunhu uye mabhenefiti eaya mapombi anoshamisa ayo ave musimboti muzvirongwa zvekuvaka zvemazuva ano.

Hydrostatic Test
Simba Risingaenzaniswi uye Kugara kwenguva refu:
ASTM A252spiral welded simbi pombiinogadzirwa nesimbi yemhando yepamusoro inosangana neASTM A252 zviyero.Iyo chiyero inovimbisa simba repamusoro uye kusimba kwepombi, ichiita kuti ive yakakodzera kune akasiyana maapplication anosanganisira oiri uye gasi kutapurirana, mirwi nheyo uye zvivakwa zvemvura.Spiral welds inowedzera kusimba uye kuramba kwepombi kumasimba ekunze, kuve nechokwadi kuti vanogona kumirisana nemamiriro ekunze ekumanikidza uye nemamiriro ekunze akaomarara.
Optimum kunyatsoshanda uye mutengo-kubudirira:
Imwe yemabhenefiti ekutanga eASTM A252 spiral welded simbi pombi ndiko kugona kwayo kwepamusoro mukuisa nekushandisa.Dhizaini yaro iri nyore kutakura uye kubata nekuda kwehuremu hwayo hwakareruka zvichienzaniswa nezvimwe zvinhu zvepombi.Pamusoro pezvo, kuchinjika kwepombi idzi kunobatsira kukotama, kuderedza zvinodiwa zvemafittings uye majoini.Izvi hazvingochengetedze nguva chete, zvakare zvinoderedza zvakanyanya mitengo yekuisa, zvichiita kuti rudzi urwu rweduti ive mhinduro inodhura kune akasiyana mapurojekiti.
Enhanced corrosion resistance:
Corrosion idambudziko guru mumapombi masisitimu, kunyanya mumaindasitiri anobata makemikari nezvinhu zvinoparadza.Iyo ASTM A252 yakajairwa inova nechokwadi chekuti spiral welded simbi mapaipi anoratidza yakanakisa corrosion kuramba.Mapombi aya ane machira ekudzivirira akadai se epoxy kana zinc anoita sechipingamupinyi kune zvinosvibisa maajenti, kuwedzera hupenyu hwavo hwesevhisi uye kuderedza mari yekugadzirisa.Iyi ficha inonyanya kubatsira mune zvepasi pevhu kana offshore application uko mapaipi anoratidzwa kune yakaoma mamiriro ekunze.
Hukuru hwekutakura:
Humwe hunhu hwakakosha hweASTM A252 spiral welded simbi pombi ndiyo yakanakisa kutakura mutoro.Spiral welding tekinoroji inoshandiswa mukugadzira inosimudzira simba repombi uye kugona kumira zvinorema.Ingave yakashandiswa mukuvaka mabhiriji, nheyo dzezvimiro kana pombi dzepasi pevhu, mapaipi aya anopa hukuru hwechimiro chekuvimbika, kuderedza njodzi yekutadza uye kuve nechokwadi chekuchengetedza kwenguva refu kweakasiyana mapurojekiti ezvivakwa.
Kuchengetedza kwezvakatipoteredza:
Munguva iyo kuchengetedza kwezvakatipoteredza kuri kunetsa pasi rose, kusarudza zvinhu zvekuvaka zvakakodzera kwakakosha.Spiral welded simbi pombi ASTM A252 inowirirana nemaitiro ekuvaka akasimba nekuda kwekusimba kwayo uye kudzokorodza zvakare.Mapombi ane hupenyu hurefu hwesevhisi uye anogona kudzokororwa zviri nyore pakupera kwehupenyu hwavo, zvichideredza kudiwa kwekubviswa kwezvinhu zvitsva uku ichideredza marara uye kuburitsa kabhoni.
Mukupedzisa:
Spiral welded simbi pombi ASTM A252 yakashandura indasitiri yepombi nesimba rayo repamusoro, kusimba uye mutengo-kushanda.Mapombi aya anosangana kana kudarika zviyero zveindasitiri, zvichivaita sarudzo yekutanga mumaindasitiri mazhinji.Hunhu hwayo hwakanakisa hwekuremerwa uye kusagadzikana kwecorrosion inovimbisa kusimudzira kwakasimba kwemapurojekiti ezvivakwa uye kubatsira mukusimudzira indasitiri yepasirese.Nekushandisa mapombi aya, mapurojekiti ekuvaka anogona kukwidziridza kushanda zvakanaka, kuderedza mitengo uye kuve nechokwadi chekuvimbika kwenguva refu uku uchiomerera kukuchengetedza kwezvakatipoteredza.
