Chidule cha Valve Yamakampani Yamlungu ndi Mlungu (2025): Thupi la Valve ya Chipata

2025-09-01

Chifukwa chake izi ndizofunikira: Kusintha kwa zinthu ndi zomangamanga zatsopano zikufanana, zomwe zikulimbitsa mphamvu m'mafakitale/ma forge, makina akuluakulu, ndi ma lab a chipani chachitatu. kuyimitsa kwaukadaulo musanafike PO ikadali njira yachangu kwambiri yotumizira katundu pa nthawi yake.

Chithunzi cha msika

  • Kuchepa kwa mphamvu zogwiritsira ntchito mipata yopangira/yopangira, makina ochapira molondola, ndi umboni wa EN 10204 3.2.

  • Tsekani chipangizocho msanga kuti musachigwiritsenso ntchito; kuzizira kamodzi kokha nthawi zambiri kumapulumutsa milungu 1-3.

Zosankha za zinthu (zoyenera kugwiritsidwa ntchito)

  • A105/low-alloy: yodalirika pa ntchito yonse, makina abwino.

  • 304/316L: Madzi/ma chloride ofatsa; 316L imapereka mpata wabwino wowononga.

  • Matupi a CF8/CF8M: yambitsani mawonekedwe ovuta a ma valve; onjezerani kuphimba kwa NDE.

  • Duplex 2205: ma chloride + mphamvu; onetsetsani kuti kutentha kuli bwino/gawo lake lili bwino.

  • Kutentha kochepa/kowawa: tchulani mfundo zomwe zingakhudze ISO 15156 / NACE MR0175kuuma kwa chivundikiro.

Miyezo (tchulani ziganizo, osati mawu ofotokozera)

Lembani zolemba ndi ziganizo za ASME B16.34, API 600/602/6D, ISO 15156, ISO 15848ndi EN 10204 (3.1/3.2). Ikani tebulo la tsamba limodzi la zikalata zochotsera msonkho, mfundo za umboni, ndi zomwe ziyenera kuperekedwa (MTC, HT, NDE, hydro/air, PMI, miyeso).

Kupanga & NDE

  • Kuyenda: preform → datums → zinthu zofunika kwambiri → kumaliza → mayeso.

  • Malo olamulira okhala ndi mpando/kuzungulira, kupingasa kwa njira ya chipata, kusalala kwa nkhope yotsogolera.

  • NDE: UT/RT (volumetric), MT/PT (surface), PMI (mix-up control); werengani ma lab msanga.

  • Gwiritsani ntchito FAI kuti muyimitse ma datum, tolerances, ndi njira zoyezera.

Mayeso a kuthamanga ndi kutayikira

Tanthauzirani njira yoyesera, kutenthandi nthawi yogwira kwa hydro. Tsimikizirani mbali ziwiri mayeso a mpando/kutuluka kwa madzi. Sungani zolemba zonse (ma ID a calibration, mikhalidwe, zomwe mwawona), osati "PASS" yokha.

Chomangira cha PO (mndandanda wazinthu zazing'ono 10-point)

  1. Maso ndi maso; flange; nkhope yotsekera (RF/RTJ)

  2. Kalasi ya zinthu + mkhalidwe wochizira kutentha

  3. NDE scope; dongosolo la umboni; mulingo wa EN 10204

  4. Kulekerera (coaxiality/perpendicularity/roughness)

  5. Yesani nthawi yocheperako/kutentha/kuimitsa; kalasi yotayira madzi

  6. Tsatanetsatane wa zizindikiro/kutsata

  7. Ndondomeko yoteteza pamwamba

  8. Phukusi la zikalata (MTC, HT, NDE, hydro/air, miyeso, CoC)

  9. Kupaka/Kuyika Ma Incoterms

  10. Zochitika zazikulu (preform, FAI, mboni, hydro, zenera la sitima)

Mfundo yofunika: Mafotokozedwe omveka bwino a ma valavu, umboni wolunjika pa masitepe osasinthika, ndi njira yowonekera bwino yofunikira zimapangitsa kuti pulogalamu ya thupi la ma valavu izidziwike bwino—pa ubwino, kutsatira malamulo, komanso panthawi yake.
