1. SY/T Standards yog dab tsi?
Teb:
SY/T yogSuav roj av thiab natural gas kev lag luam qauv, tswj:
Scope: Kev tshawb nrhiav roj/gas, drilling, pipeline tsim, thiab khoom siv.
Txoj cai: Tshaj tawm los ntawm Tuam Tshoj National Energy Administration (NEA).
2025 Hloov tshiab: Kev koom ua ke nrog ISO/API cov qauv rau cov haujlwm thoob ntiaj teb (xws li SY/T 7397-2025 ua raws li API 5L).
Cov qauv tseem ceeb sib npaug:
API (American Petroleum Institute)
ISO 3183 Cov kav dej thoob ntiaj teb
GB / T (Suav teb chaws tus qauv)
2. Cov qauv SY/T piv rau API/ISO li cas?
Teb:
| Parameter | SY/T | API/ISO |
|---|---|---|
| Kev txiav txim | Yuav tsum tau nyob hauv Suav teb | Ntiaj teb no yeem txais yuav |
| Technical Rigor | Kev xeem HIC/SSC nruj dua | Tsom ntsoov rau qhov yooj yim tsim |
| Hloov tshiab | Kev kho txhua xyoo (piv txwv li, SY/T 4109-2025) | 3-5 xyoo cycles |
Piv txwv: SY/T 5040-2025 (kab yeeb nkab welds) tam sim no xav tauAI-based NDT, dhau API 1104.
3. Cov qauv SY/T tseem ceeb rau cov kav dej yog dab tsi?
Teb:
SY/T 5037-2025: Kauv submerged arc welded kav (hloov GB / T 9711 rau onshore tej yaam num).
SY/T 5992: Seamless casing/tubing (2025 hloov tshiab ntxiv hydrogen kuj clauses).
SY/T 4103: Pipeline txheej (txheej txheem 3LPE/3LPP rau hla- lub teb chaws pipelines).
SY/T 0452-2025: X-Kev kuaj kab hluav taws xob (zoo li ISO 17636-2).
Txoj Kev: SY/T qauv tam sim no dominateTuam Tshoj Sab Hnub Poob -Tebchaws Gas Pipeline Phase IV.
4. Yuav tsum muaj ntawv pov thawj dab tsi rau kev ua raws li SY/T?
Teb:
Factory Audits: Los ntawm Tuam Tshoj Classification Society (CCS) los yog NEA- pom zoo lub cev.
Kev sim:
SSC/HIC xeem rau SY/T 0599-2025 (NACE TM0177 sib npaug).
Automated UT rau kev soj ntsuam vuam (SY/T 6423.6-2025).
Cov ntaub ntawv: Ob hom lus (Suav / Lus Askiv) zeb ntawv pov thawj nrog QR cov lej.
Cov lus qhia txog kev yuav khoom: Txheeb xyuasSY/T 4204-2025ua raws li cov kev pabcuam qaub.
5. Yuav ua li cas siv SY/T cov qauv thoob ntiaj teb?
Teb:
Hybrid Designs: Muab SY/T nrog API/ISO (piv txwv li, SY/T 4111 + API 5L rau Eurasian pipelines).
Localization: Siv SY/T 7348-2025 rau CNG chaw nres tsheb hauv Belt & Road lub teb chaws.
Kev cob qhia: NEA-cov txheej txheem vuam (piv txwv li, SY/T 4109-2025 WPS).
Summary & Cov Lus Qhia
Rau Tuam Tshoj Projects: Ua ntej SY/T dhau API/ISO rau kev ua raws cai.
Ntiaj teb no tej yaam num: SivSY/T-API cross-mapping tables(tshaj tawm los ntawm NEA hauv 2025).
Kev tsim kho tshiab: Txais SY/T 7350-2025 raudigital twin pipeline tswj.
