Complete building gas installation inspection per ABNT NBR 15526. Leak testing, pressure tests, and safety compliance for natural gas and LPG systems. CREA-licensed mechanical engineer with ART-backed inspection reports. Comparable to NFPA 54 / ANSI Z223.1.
Gas installation safety is regulated by ABNT standards and enforced by gas distribution companies. Every building with gas supply must maintain compliant piping, regulators, and safety devices.
Most gas incidents result from deteriorated piping, faulty regulators, or improper connections. Regular inspection identifies hazards before they become life-threatening emergencies.
We cover all types of building gas installations — natural gas and LPG — for residential, commercial, and industrial applications.
Complete natural gas distribution networks — main supply, branch piping, individual connections. Tightness testing, pressure verification, and joint inspection per ABNT NBR 15526.
Liquefied petroleum gas installations — central tank systems, cylinder batteries, vaporizers, distribution piping. Compliance with NBR 13523 and gas company regulations.
First-stage and second-stage pressure regulators, pressure relief valves, regulator stations. Pressure setting verification, relief valve operation, and regulator condition assessment.
Manual and automatic shutoff valves, excess flow valves, seismic shutoff devices. Valve accessibility, operation testing, and emergency shutoff verification.
Fixed gas detection panels, sensors, alarm systems, and automatic shutoff integration. Sensor calibration verification, alarm function testing, and system response assessment.
Industrial gas-fired equipment — boilers, furnaces, ovens, dryers. Burner inspection, combustion analysis, safety interlocks, and flame safeguard systems per NBR 12313.
Every inspection includes a detailed ART-backed technical report with piping diagrams, pressure test records, leak detection results, photographic evidence of non-conformities, and corrective recommendations — all signed by a CREA-registered mechanical engineer.
| Brazilian Standard | Purpose | International Equivalent |
|---|---|---|
| ABNT NBR 15526 | Gas installation networks | NFPA 54 / ANSI Z223.1 |
| ABNT NBR 13523 | Central gas system installation | ASME B31.1 |

Yes. ABNT NBR 15526 establishes mandatory requirements for gas installation inspection in buildings. Gas distribution companies (e.g., Comgás, Naturgy, Cegás) require periodic inspection and tightness testing before connecting or reconnecting gas supply. Condominiums must also comply with state and municipal regulations that mandate periodic gas system audits to ensure safety and prevent leaks.
The primary standard is ABNT NBR 15526 (Gas installation networks for residential and commercial buildings). Additional applicable standards include ABNT NBR 13523 (Central gas system installation), NR-13 (for pressurized systems where applicable), and NBR 12313 (Gas-fired industrial heating systems). State gas company regulations also apply. These are comparable to NFPA 54/ANSI Z223.1 and ASME B31.1 internationally.
A gas system inspection includes: visual inspection of all gas piping and fittings, tightness testing (leak detection using calibrated instruments), pressure testing of the piping network, verification of pressure regulators and safety valves, inspection of gas meters and connections, assessment of ventilation and venting in gas appliance areas, verification of shutoff valve operation, and review of appliance connections and flexible hose condition. All results are documented in an ART-backed technical report.
Gas systems should be inspected at intervals defined by the local gas distribution company and state regulations — typically every 3 to 5 years for residential buildings and annually for commercial and industrial installations. Additionally, inspection is required whenever there is a suspected leak, after any modification to the gas piping, before reconnection after extended shutoff, and for new installations before initial gas supply.
Yes. We deliver bilingual documentation — the official inspection report and ART in Portuguese (as required by Brazilian authorities and gas distribution companies) plus an English translation for your corporate records. All communication during the inspection process is conducted in English.
