X60 Spiral Submerged Arc Welded Line Pipe ya Mapaipi a Mafuta

Kufotokozera Kwachidule:

Kufunika kwa mafuta ndi gasi kukukulirakulirabe, ndipo kumafunanso kufunikira kwa mapaipi ogwira mtima komanso odalirika.Apa ndipamene chitoliro cha mzere wa X60 SSAW chimayamba kuseweredwa.Mtundu uwu wa spiral steel pipe ndi chisankho chodziwika bwino pakupanga mapaipi amafuta ndipo imapereka zabwino zambiri zomwe zimapangitsa kuti ikhale yankho labwino pamayendedwe amafuta ndi gasi.

Kuyesedwa kwa Hydrostatic

Mmodzi mwa ubwino waukulu waX60Chithunzi cha SSAWndi mphamvu zake zazikulu.Chitolirochi chimakhala ndi mphamvu zochepa zokolola za 60,000 psi, zomwe zimapangitsa kuti zikhale zoyenera pazovuta zapamsewu zoyendera mafuta ndi gasi.Njira yowotcherera yozungulira imatsimikiziranso kuti chitolirocho chimakhala ndi makulidwe a khoma lofanana, zomwe zimawonjezera mphamvu zake ndi kudalirika.

Kuphatikiza pa mphamvu, chitoliro cha mzere wa X60 SSAW chimadziwika chifukwa cha ductility komanso kulimba kwake.Izi zikutanthauza kuti chitolirocho chimatha kupirira zovuta ndi zovuta zamayendedwe ndi kukhazikitsa popanda kusokoneza kukhulupirika kwake.Izi ndizofunikira makamaka pamapaipi amafuta, omwe nthawi zambiri amafunikira kudutsa malo ovuta ndikugonjetsa zopinga zosiyanasiyana pomanga.

Kuphatikiza apo, chitoliro cha mzere wa X60 SSAW sichichita dzimbiri, ndikupangitsa kuti chikhale chokhalitsa komanso chotsika mtengo cha mizere ya mapaipi amafuta.Njira yowotcherera yozungulira imapanga malo osalala komanso ma welds osasinthasintha, kuchepetsa chiopsezo cha dzimbiri ndikukulitsa moyo wa chitoliro.Izi ndizofunikira kwambiri kwa mafutapayipis, zomwe zimakhudzidwa ndi zinthu zowononga komanso zachilengedwe zomwe zingawononge zinthu zosauka.

Pomanga mapaipi amafuta, chitetezo ndi kudalirika ndizofunikira kwambiri.Chitoliro cha mzere wa X60 SSAW chimayika mabokosi onse pano, kupereka yankho lamphamvu, lolimba komanso losachita dzimbiri lomwe limatha kupirira zovuta zamayendedwe amafuta ndi gasi.Mphamvu zake zazikulu, ductility kwambiri ndi kulimba kwamphamvu zimapangitsa kukhala chisankho chodalirika pama projekiti ovuta kwambiri a mapaipi.

Mwachidule, chitoliro cha mzere wa X60 SSAW ndiye chisankho choyamba cha mapaipi amafuta chifukwa cha mphamvu zake zapamwamba, kulimba kwake komanso kukana dzimbiri.Njira yake yowotcherera yozungulira imapanga mapaipi omwe amatha kupirira kupsinjika kwakukulu, malo ovuta komanso malo owononga, kuwapanga kukhala njira yodalirika komanso yotsika mtengo yoyendetsera mafuta ndi gasi.Popanga mapaipi amafuta, kusankha chitoliro cha X60 spiral submerged arc welded pipeline ndi chisankho chotsimikizira chitetezo ndi kudalirika kwa ntchito yonse.
