Aksa Bursa Şehiriçi natural gas project approval and drawing – Bursa, Türkiye
In the Bursa service area, indoor gas installation projects are reviewed by Aksa Bursa Şehiriçi Doğal Gaz Dağıtım Ticaret ve Taah A.Ş., part of the Aksa group. Below you will find the rules the app applies, the specification status and a checklist to go through before you apply.
Rules: TS 7363 common
Specification and calculation rules
Aksa's Indoor Installation Design and Application Rules (2019 Rev.01) have been read. The document leaves the calculation values to the TS 7363:2018 standard, and since the text of the standard has not been read, the calculation limits use a common profile, based on TS 7363 general rules. This page and the values in the app will be updated when the standard is uploaded.
Rules from the Aksa document built into the app
- DN15 is not used in welded installations inside a flat (art. 2.10); automatic sizing picks DN20 or larger.
- No tee branch is made at the meter outlet just before the pipe enters the flat (art. 2.9).
- Inlet valves are of the lockable type and unused outlets are sealed and blanked (art. 2.7); the main shut-off valve and the meter valve carry an OPEN-CLOSED sign (art. 2.5).
- Type C or condensing appliances up to 50 kW may be placed outdoors in a ventilated cabinet (art. 2.15).
Values used in the calculation
| Service box → meter loss limit | 1 mbar |
|---|---|
| Meter → appliance loss limit | 0.8 mbar |
| Velocity limit (low pressure) | 6 m/s |
| Friction loss, steel | formula at all flows (23.2·R·Q^1.82/D^4.82, R = 0.6) |
| Efficiency in appliance flow | 90% at 70 kW and above |
| Isometric angle | 30° |
