Argentina Natural Gas Pipeline Project Shipment & BV Third-Party Verification

Mapaipi ndi magawo ena a mapaipi amaliza kuyang'anira -ndi gulu lachitatu pulojekiti yopanga mapaipi a gasi ku Argentina{1}}komwe kuwongolera zinthu, kulondola kwa dimensional, ndi traceability -zingatheke.

Chomwe chidadziwika bwino pakumasulidwa uku nditight bore (ID) controlndizotsatira za kuuma kwapamwambapaASTM A106 Gulu B (ASME B36.10) mapaipi opanda msoko,pamodzi ndikutsata-pawiri kokhazikikazofunika ndi polojekiti.

Phukusili limakwirira chitoliro cha chitsulo cha kaboni ndi zida zofananira zamapaipi opangira kufalitsa mpweya, kuphatikiza:

• Chitoliro cha Mzere:API 5L SAWL (makalasi a pulojekiti akuphatikiza X52 / X70; X70 cholemba chitsanzo chojambulidwa poyendera)
• Chitoliro Chopanda Msoko:ASME B36.10,Chithunzi cha ASTM A106 B, BE, 11.7 m
• Flanges: MSS SP-44 + ASME B16.5, zipangizo kuphatikizapoChithunzi cha ASTM A694 F42 (290) / F52 (360) / F70 (485); kuphatikiza zinthu za ASME B16.5 A105
• Threadolet:MSS SP-97,Chithunzi cha ASTM A694 F52 (360)
• Spiral Wound Gasket:ASME B16.20; zinthu kasinthidwe zikuphatikizapo304SS + graphite yosinthika(FG) mu kuphatikiza kwa mphete / mphete yamkati
• Stud Bolts + Heavy Hex Nuts:kutsimikiziridwa kwa boltChithunzi cha ASTM A193 B7 / ASTM A194 Gr. 2H
• Reducer Eccentric / Cap / Tee:Zinthu za MSS SP-75 kuphatikizaGr. WPHY-52ndiGr. WPHY-70

Pazinthu zambiri zopanga mapaipi, ma flange amakhala "cholepheretsa kuvomereza" chifukwa zojambula, makalasi, ndi mawonekedwe a nkhope ziyenera kugwirizana bwino.

Gulu ili likuphatikizapokuwotcherera khosi flangesopangidwa ndi kusindikizidwa ku MSS SP-44 ndi ASME B16.5, ndi-mphamvu zazikuluASTM A694magiredi (F42/F52/F70) ogwiritsidwa ntchito m'masaizi ndi mawerengero ofunikira.

Bore (ID) ndi Dimensional Control (Zotsatira Zojambulidwa)

• NPS 16" SCH80, 11.7 m:

ID yoyezedwa365.2-366.8 mm (a 1.6 mmzenera), ndi kutalika kwake11726-11730 mm

• NPS 24" SCH80, 11.7 m:

ID yoyezedwa545.6-548.1 mm (a 2.5 mmzenera), ndi kutalika kwake11714-11717 mm

M'mawu omveka: kufalikira kolimba kumatanthauza kuti "chifukwa chiyani izi sizikukhazikika" nthawi zocheperako-panthawi yolumikizana.

Kuvuta Pamwamba (Asanapente)

• NPS 24 mapaipi: 123-162 µin
• NPS 16 mapaipi: 134-167 µin

Pagululi, -zochitika zowunikira gulu lachitatu zikuphatikizidwakuyang'ana kowoneka, kutsimikizira kuchuluka, kuyang'ana mawonekedwe, kutsimikizira chizindikiro, ndikuwunikanso zolemba-ndi macheke ena mongakutsimikizira kwa ellipalitykwa SAWL mzere chitoliro.

Kwa bolting ndi ma gaskets, kuyenderako kudalembedwansokuyesa kokwanira bawuti/nati(kupewa kugwidwa kwa ulusi / kuphatikizika pachiwopsezo) ndikutsimikizira kutchulidwa kwa zinthu za gasket ndikuwunika kuti zitsatidwe.

FAQ

 

 

01.Kodi zotsatira zotsimikizika zamkati mwake (ID) za mapaipi a ASTM A106 Gr.B opanda msoko a SCH 80 zinali zotani?

Ma ID ojambulidwa anali365.2–366.8 mm (NPS 16 SCH 80, 11.7 m)ndi545.6–548.1 mm (NPS 24 SCH 80, 11.7 m)-kuwonetsakuwongolera kwamphamvu kwambiriza kukonza{0}}zokwanira.

02.Ndimikhalidwe yanji yakukhara pamwamba yomwe idayesedwa pa mapaipi a A106 Gr.B (asanapente)?

Mawerengedwe ovuta anali123–162 µin (NPS 24)ndi134–167 µin (NPS 16), kuthandizira amalo oyerakwa kukonzekera zokutira ndi kuvomereza.

03.N'chifukwa chiyani onse a MSS SP-44 ndi ASME B16.5 amawunikidwa pa ma flange a Class 600?

Mapulojekiti a mapaipi nthawi zambiri amafotokozera momwe mungasinthire zojambula / ma PO; flanges chizindikiro ndi kutsimikiziridwa kutiMSS SP-44 + ASME B16.5(ndiASTM A694 F42/F52/F70) kuchepetsa chiopsezo chakukana kufananiza koyenerapakulandila ndi kuwunika kwa QA.

04.Kodi ma stud bolt/mtedza aziyitanitsa bwanji kuti apewe kuchedwa-patsamba?

NenaniASTM A193 B7 / ASTM A194 2H, otentha-dip galvanizing to ASTM F2329, chabwinokutalika / ulusi chinkhoswe, ndi kufunakuyesa kokwanira kwa bolt-nutkupewa kugwidwa kwa ulusi ndi kuyimitsidwa kwa msonkhano.
