API Gas Pipe Repair at Modena on 13 Mar 2026

📍Modena | 🏨 Condo

API Gas Pipe Repair became necessary after the replacement of the owner’s old gas heater. Upon completion of the installation, a final gas pressure test was conducted to verify that the gas system complied with Gas Supply Regulation 21. However, the system failed the test, indicating a leak within the existing gas piping network.

Due to the potential safety risk and regulatory non-compliance, our technician immediately shut off the gas supply valve at the gas meter, following the instruction of our Licensed Gas Service Worker (LGSW), Mr. Chew, to prevent any further gas leakage.

Subsequently, API Gas Pipe Repair works were carried out to rectify the defective section of the gas piping and restore the gas system to a safe and compliant operating condition.

⚠️ Issue Found

During the final gas pressure test conducted after the gas heater replacement, our technicians—working under the supervision of a Licensed Gas Service Worker (LGSW)—identified a failure in the gas system pressure integrity test.

  • Rust and corrosion were observed on sections of the existing API gas pipe.
  • Material wear and deterioration caused by long-term usage and environmental exposure.
  • Gas leakage detected during pressure testing, indicating compromised pipe integrity.

Further inspection confirmed that the corrosion had weakened the pipe wall structure, resulting in leakage under test pressure conditions. The affected piping no longer met the safety requirements under the Gas Supply Regulations and SS608 gas installation standards.

Due to the safety risk associated with gas leakage, the defective pipe section required immediate API gas pipe repair works to restore system integrity and ensure compliance with regulatory standards.

⚠️ Conditions Leading to the Gas Pipe Issue

During the inspection of the gas piping system, several underlying factors were identified that contributed to the deterioration of the existing API gas pipes. These conditions developed progressively over time and ultimately led to the failure observed during the pressure testing stage.

1. Ageing Gas Piping System

  • The existing gas pipes have been in service for an extended period.
  • Long operational lifespan increases the likelihood of material fatigue and structural weakening.

2. Rust and Corrosion on API Pipes

  • Visible corrosion was observed on sections of the API gas piping.
  • Rust formation over time reduces pipe thickness and compromises gas-tight integrity.

3. Wear and Tear from Long-Term Usage

  • Continuous use over many years contributes to gradual degradation of pipe materials.
  • Connections and joints may weaken, increasing the risk of leakage under pressure.

4. Moisture Exposure and Environmental Factors

  • Possible exposure to moisture or humid conditions can accelerate corrosion.
  • Environmental factors may speed up the deterioration process of metal piping components.

If left unresolved, these conditions can significantly compromise the safety, reliability, and structural integrity of the gas supply system. Timely repair and compliance with gas installation standards are essential to prevent leakage risks and ensure safe operation for the occupants.

Final Pressure Test

SS 608:2024 Compliance

After completing the API Gas Pipe Repair, our team performs a final pressure test to ensure the system is safe and gas-tight.

📏
Test Pressure
450 mm w.g.
⏱️
Test Duration
5 Minutes
✅
Purpose
Leak Check

The gas piping system is pressurized to 450 mm w.g. for 5 minutes, in accordance with Singapore Standard SS 608:2024. During this period, we carefully monitor for any pressure drop or leakage.

This test confirms that the installation is leak-proof, safe for use, and fully compliant with regulations before handing over to the homeowner.

🔧 Repair Work & Compliance – Gas Pipe Restoration

To rectify the issue identified during the pressure testing stage, API gas pipe repair works were carried out to restore the integrity of the existing gas system. The damaged sections of the API gas pipe were carefully repaired through professional welding, strengthening the pipe structure and restoring its gas-tight sealing performance.

This repair ensured that the compromised pipe sections were reinforced and capable of safely withstanding normal operating gas pressure without leakage, thereby returning the system to a safe operational condition.

📋 Regulatory Compliance

All repair works were carried out in strict accordance with the relevant gas installation regulations and standards, including:

  • Gas Supply Regulations – Regulation 21 for gas pressure testing and safety requirements.
  • SS 608 – Singapore Standard for Gas Installation, ensuring proper workmanship and installation practices.

Compliance with these regulations is critical to ensure that the gas system remains safe, leak-free, and fully approved for operation. Proper adherence to regulatory standards also protects homeowners by ensuring that all gas installations meet Singapore’s stringent safety requirements.

Homeowners play an important role in ensuring that their gas installation remains safe and compliant with Singapore gas safety regulations. Proper maintenance, timely repairs, and professional inspections can help prevent gas leakage risks and ensure reliable operation of the gas supply system.

Homeowners should ensure the following:

  • Gas installations and repairs are always performed by Qualified Professionals.
  • A Final Pressure Test is conducted after any gas appliance replacement or modification to the gas piping system.
  • Old, corroded gas pipes are promptly repaired or replaced to prevent leakage risks.
  • All works comply with the Gas Supply Regulations and Singapore Standard (SS608).

Proper API gas pipe repair and regulatory compliance help to prevent gas leaks, improve system reliability, and most importantly protect the safety of the home and occupants.
