Periodic inspection of natural gas installation., Natural gas installation inspection is the regular inspection of an internal gas system for gas leaks, combustion safety, and exhaust gas discharge. Since gas leaks pose a risk of fire, explosion, and carbon monoxide (CO) poisoning, periodic inspections are a legal requirement in industrial, commercial, and public use facilities. AES Innovation provides natural gas installation inspections. with our authorized engineers It operates in accordance with relevant standards and regulations.
Short answer: Natural gas installation inspection includes leak (pressure) testing, gas line and equipment checks, burner/combustible combustion assessment, and flue/flue gas discharge checks. The aim is to prevent the risks of gas leaks, explosions, and CO poisoning.
What is a Natural Gas Installation Inspection?
Natural gas internal installation inspection verifies the safety and suitability of the pipeline, valves, regulators, flexible connections, combustion devices, and chimney system from the meter outlet to the gas-burning appliances. It is applied in industrial boiler rooms, commercial kitchens, production facilities, and public buildings.
Why is it critical?
- Risk of explosion: A gas leak can accumulate in the environment and lead to an explosion.
- CO poisoning: Incomplete combustion and faulty chimneys produce deadly carbon monoxide.
- Legal requirement: Gas distribution companies and regulations require periodic inspections.
- Business continuity: Non-compliance could result in gas outages and production stoppages.
Scope of Inspection
- Leakage (pressure) test: Verification of the pipeline for gas leaks.
- Pipeline and connections: Corrosion, suspension, distance, and access control.
- Valve, regulator and meter: Location, accessibility and operational control.
- Burner/combustion devices: Combustion quality and safety equipment.
- Flue and exhaust gas discharge: Traction, sealing, and fit.
- Ventilation and gas alarm/detector: Competency and work control
Technical Test Criteria (TS EN 1775 / TS 7363)
Inspection of natural gas internal installations is carried out according to TS EN 1775 and TS 7363 standards based on the maximum permissible operating pressure (MOP); pressure tests are based on TS EN 12327 principles.
| Test / Criteria | Basis | Standard |
|---|---|---|
| Strength test | Pipeline integrity — at test pressure above MOP | TS EN 1775 / TS EN 12327 |
| Tightness test | No pressure drop at the specified test pressure. | TS EN 1775 / TS EN 12327 |
| Scope — indoor gas installation | MOP ≤ 5 bar | TS EN 1775 |
| Flue gas | CO and flue gas measurement | TS 7363 / device specification |
Values are summarized based on TS EN 1775 and TS 7363; the applicable test pressure, duration, and period are determined according to the relevant gas distribution company procedures and installation class.
AES Innovation Inspection Process
- Document review: Project, gas connection permit and previous reports.
- Visual examination: Line, equipment, chimney and ventilation inspection.
- Leakage test: Gas leak verification via pressure test.
- Combustion and chimney assessment: Combustion device and exhaust gas control.
- Reporting: Report including non-conformities and recommendations for corrective action.
Commonly Encountered Nonconformities
- Leaky connections and worn flexible hoses
- Inadequate ventilation and missing gas detector.
- Insufficient chimney draft and exhaust gas leakage.
- Corroded or improperly hung lines
- Safety valve/regulator malfunctions
- High CO levels due to incomplete combustion.
Relevant Standards
Natural gas installation inspections; TS 7363 (internal installation), TS EN 1775 (building gas installation), TS EN 15001 (industrial/commercial gas installations), related Internal Installation Regulations and is carried out in accordance with the specifications of the gas distribution company. (Natural gas installation inspections are outside the scope of AES's TÜRKAK accreditation and are carried out by our authorized engineers.)
Frequently Asked Questions
How often should natural gas installations be checked?
For industrial and commercial facilities, a periodic annual inspection is generally recommended; the gas distribution company and regulatory requirements are the determining factors.
How is a leak test performed?
The line is pressurized with a gas-free fluid at a specified pressure, and the pressure drop is monitored to verify leaks.
Who prepares the inspection report?
Our authorized engineers conduct the inspections and prepare a periodic inspection report detailing any non-conformities.
Frequently Asked Questions
Doğal gaz tesisatı muayenesinde nelere bakılır?
Mukavemet (basınç) ve sızdırmazlık testleri, boru ve bağlantı bütünlüğü, basınç düşürme istasyonları, havalandırma ile baca gazı (CO) kontrolü TS EN 1775 ve ilgili standartlara göre değerlendirilir.
Test basıncı ve kontrol periyodu nasıl belirlenir?
Test basıncı ve kontrol periyodu, tesisatın azami işletme basıncına (MOP) ve gaz dağıtım/işletme prosedürlerine göre belirlenir; tek ve sabit bir değer yoktur.
Doğal gaz tesisatı muayenesini kim yapar?
The inspection is carried out independently by our qualified engineers.
