X60 Spiral Yakanyura Arc Welded Line Pipe Yemafuta Mapaipi
X60 SSAW mutsetse wepombi, inozivikanwawo se spiral undermerged arc welded pipeline pipe, inoshandisa macoil esimbi anopisa semidziyo inoshandiswa kupeta tambo kuita mapaipi.Iyi nzira yekugadzira inoita kuti pombi isangosimba uye yakasimba, asiwo inopesana zvikuru nekuora uye kushungurudzika.Hunhu uhu hwakakoshapombi yemafuta mitsetse, iyo inowanzoiswa pasi pemamiriro ezvinhu akaoma ezvakatipoteredza uye mamiriro ekudzvinyirira.

Hydrostatic Test
Imwe yemabhenefiti makuru eX60SSAW mutsetse pombindiro simba rayo guru.Iyi pombi ine simba shoma regoho re60,000 psi, zvichiita kuti ive yakakodzera kune zvakanyanya-kudzvanywa zvinodiwa zvekufambisa kwemafuta uye gasi.Iyo spiral welding process inovimbisawo kuti pombi ine yunifomu yemadziro ukobvu, iyo inowedzera kuwedzera simba rayo uye kuvimbika.
Pamusoro pesimba, X60 SSAW mutsetse pombi inozivikanwa nekunaka kwayo ductility uye kukanganisa kuoma.Izvi zvinoreva kuti pombi inokwanisa kumira kushushikana uye kushushikana kwekutakura uye kuisa pasina kukanganisa kuvimbika kwayo.Izvi zvinonyanya kukosha kune mitsara yepombi yemafuta, iyo inowanzoda kuyambuka nzvimbo yakaoma uye kukunda zvipingamupinyi zvakasiyana panguva yekuvaka.
Pamusoro pezvo, X60 SSAW mutsara wepombi inodzivirira-kuora zvakanyanya, ichiita kuti ive yenguva refu uye inodhura-mhinduro yemapombi emafuta.Iyo spiral welding process inogadzira nzvimbo yakatsetseka uye inowirirana welds, kuderedza njodzi yekuora uye kuwedzera hupenyu hwepombi.Izvi zvakakosha kune mafutapipelines, iyo inoratidzwa kune zvinoparadza zvinhu uye zvakatipoteredza izvo zvinogona kukanganisa hurombo hwemhando yezvinhu.
Mukuvaka pombi yemafuta, kuchengetedzwa uye kuvimbika ndiko kwakakosha.X60 SSAW mutsetse wepombi inokwenya mabhokisi ese pano, ichipa yakasimba, yakasimba uye isingaite ngura mhinduro inogona kumirisana nekuoma kwekufambisa kwemafuta negesi.Simba rayo repamusoro, ductility yakanakisa uye kuoma kwemhedzisiro inoita kuti ive sarudzo yakavimbika kune yakanyanya kunetsa pombi mapurojekiti.
Muchidimbu, X60 SSAW mutsara pombi ndiyo yekutanga sarudzo yemapombi emafuta nekuda kwesimba rayo repamusoro, kusimba uye kusagadzikana kwekuora.Yayo spiral welding process inogadzira mapaipi anokwanisa kumirisana nedzvinyiriro huru, inonetsa nharaunda uye nzvimbo dzine ngura, zvichiita kuti ive yakavimbika uye inodhura mhinduro yekufambisa oiri negasi.Paunenge uchigadzira mapaipi emafuta, kusarudza X60 spiral undermerged arc welded pombi pombi isarudzo yekuve nechokwadi chekuchengetedza uye kuvimbika kwese kushanda.
