3. Rhaid i ddeunyddiau fod yn unol â safonau ASTM A105, ASTM A694 F65 ac ASTM A694 F70.
| 4. Rhaid diffodd a thymheru fflansau ASTM A694 F65 ac ASTM A694 F70. | 5. Rhaid sicrhau bod tystysgrifau profi deunyddiau ac adroddiadau trin gwres ar gael ar gyfer archwiliadau TPI. |
| 6. Rhaid i fflansau WN fod â phennau bevel yn unol ag ASME B16.25. | 7. Rhaid i werthoedd prawf cemegol a mecanyddol deunyddiau (effaith, cynnyrch, tynnol ac ati) fod yn unol â safonau cysylltiedig. |
| 8. Rhaid peiriannu a farneisio pob arwyneb ag olew tryloyw i atal rhydu. | 9. Rhaid i farcio gynnwys y wybodaeth ganlynol, |
| • Diamedr (rhagolwg 6”) | • Dosbarth pwysau (dewisol o 150 pwys) |
| • Gradd Deunydd (yn cynnwys ASTM A 105) | • Trwch wal (rhagweladwy 4.78 mm) |
| Material | • Safon gynhyrchu (ASME B16.5)10. Rhaid i ddeunyddiau fod yn rhydd o unrhyw ddiffygion a chraciau arwyneb. Gwaherddir atgyweiriadau weldio yn llym. |
| 11. Rhaid i bob fflans fod ag wyneb codi (RF) gydag arwyneb selio. Rhaid i'r arwyneb selio fod yn Ra 3,2 – 6,3 µm (125 – 250 mic. inc.) yn unol ag ASME B46.1.12. Rhaid pacio deunyddiau i atal difrod i beiriannu ac arwynebau selio. | |
| 13. Rhaid i bob dimensiwn fod mewn goddefiannau positif (+). Gwaherddir goddefiannau minws yn llym.14. Rhaid gwneud beveliadau fflans yn unol ag ASME B16.25. | |
| 15. Bydd y broses weithgynhyrchu yn cael ei gwirio ar unrhyw adeg gan TPI.16. Gall TPI gymryd samplau o unrhyw ddeunydd ar gyfer sampl prawf cemegol/mecanyddol. | |
| 17. Bydd adroddiad arolygu sy'n dod i mewn yn cael ei adolygu gan TPI. | |

Pipe fittings are crucial components in the piping system, used for connection, redirection, diversion, size change, sealing or controlling the flow of fluids. They are widely applied in fields such as construction, industry, energy and municipal services.
Key Functions: It can perform functions such as connecting pipes, changing flow direction, dividing and merging flows, adjusting pipe diameters, sealing pipes, controlling and regulating.
Application Scope:
- Building water supply and drainage: PVC elbows and PPR tris are used for water pipe networks.
- Industrial pipelines: Stainless steel flanges and alloy steel elbows are used to transport chemical media.
- Energy transportation: High-pressure steel pipe fittings are used in oil and gas pipelines.
- HVAC (Heating, Ventilation, and Air Conditioning): Copper pipe fittings are used to connect refrigerant pipelines, and flexible joints are used for vibration reduction.
- Agricultural irrigation: Quick connectors facilitate the assembly and disassembly of sprinkler irrigation systems.
