Engineering Overview
ASTM A333 Giredhi 6 inovhara mapaipi esimbi asina musono uye akakandwa anoshandiswa patembiricha yakaderera kusvika -50 dhigirii F (-46 dhigirii).
Simbi inogadzirwa kuti ichengetedze kuomarara pasi pemamiriro epasi, inotsigira kuchengetedzwa kwakachengeteka uye kugadzikana kwemaitiro mukuda cryogenic masisitimu akadai seLNG terminals, gasi kugadzira gasi, uye arctic pombi zvivakwa.
Makiyi ekuita maitiro:
- Crack resistance pasi pekupisa kwekupisa
- Simba rakagadzikana panguva yekutonhora kwekutanga kutenderera
- Kuvimbika weldability kuti munda kugadzwa
- Inoenderana ne-tembiricha yeASME pressure system

Kugadzira & Kupisa Kurapa
Mapombi eASTM A333 Grade 6 anogadzirwa asina musono kana sepombi dzakasungwa, asi muzviitiko zvese izvi zvinogadziriswa kuti zvienderane-nekusimba kwekusimba kwakadzikira. Kugadzirwa kunotanga neakachena, -simbi yezviyo kuti ive nechokwadi chekuti zvinhu izvi zvinokwanisa kupinza tembiricha pasi pe zero. Maumbirwo nekukura zvinodzorwa kuitira kuti pombi irambe iine OD chaiyo, mudhuri uye kutwasanuka, zvinova zvakakosha kana mitsetse yagadzirwa kare uye yakaiswa simbi-. Yemukati yepamusoro mhando inotariswa zvakare kuchengetedza yakanaka kuyerera maitiro emafuta, gasi kana utility media.
Mushure mekugadzirwa, mapaipi anoiswa kuburikidza neyakadzora kupisa-kutenderera kwekurapa. Danho iri harisi rekungobvisa kushushikana - rinonyanya kudzosa ductility uye kunyange kunze kweiyo microstructure kuitira kuti Charpy inokanganisa kukosha pa-45 dhigirii (kana tembiricha inotsanangurwa muhurongwa) igone kusangana. Kudzikamisa kwakaringana kana kudzikisira kunonatsa tsanga, kunonatsiridza kusimba, uye kunopa pombi kuramba kuri nani pakuitika kamwe kamwe kana kushanduka kwesimba mumamiriro ekutonhora-sevhisi.

Welding uye Kugadzirwa kweCryogenic Pipeline Kutendeseka
ASTM A333 Giredhi 6 inopa yakagadzikana weldability yekusangana modular uye kuvaka munda.
Zvakadaro, kupisa-affected zone (HAZ) zvivakwa zvinofanirwa kuchengetedzwa nemazvo kuitira kuti-tembiricha ishande yakaderera:
- Welding process kuenderananeSMAW, GTAW, uye GMAW yezvose zviri zviviri zvechitoro nemunda
- Yakakodzera WPS/PQRinodiwa kusimbisa kuomarara kwemhedzisiro mushure mekudzikisira mumabasa ecryogenic
- Kudzora kupinza kwekupisakudzivirira kukoromoka kwezviyo uye kurasikirwa kwekuoma kwenotch muHAZ
- PWHT zvichienderana nemamiriro ebasauye dhizaini kodhi zvinodiwa kuti uvandudze weld joint uniform
- Weld musono kuongorora (UT/RT)yakakurudzirwa kuLNG uye arctic application ine yakakwira mhedzisiro yekutadza
Kushandiswa kwepaipi yakasimwa kunochengetedza kusaputsika uye kudonha-kwakasimba kushanda pasi pekutanga kutonhora.
