General Background Quality control implementation within gas distribution pipeline installation ensures operational reliability and structural integrity. Specific Background Polyethylene pipes are widely chosen for gas distribution projects due to flexibility, corrosion resistance, and jointing efficiency, requiring rigorous pressure testing prior to commissioning. Knowledge Gap Although pneumatic testing using pressurized air is commonly conducted to verify joint strength, empirical evaluations documenting step-up holding pressure stability and operational quality control protocols during field assembly remain limited. Aims This study evaluates quality control procedures during 180 mm polyethylene pipe installation in a gas network project at PT. XYZ using the pneumatic test method. Results Qualitative and quantitative case evaluation shows that holding test pressures at 43.551 psig (July) and 42.451 psig (August) for 4.5 hours maintained absolute stability without pressure drops or joint leaks. Novelty Systematic step-up, holding, and step-down pressure monitoring validates butt fusion and electrofusion integrity under pressurized air conditions in distribution pipelines. Implications Adhering to standardized pneumatic test protocols guarantees network safety, minimizes minor joint imperfections, and prevents long-term gas leakage.
Key Findings Highlights
Pneumatic Testing Validates Joint Integrity At Maximum Holding Pressures Exceeding 42 Psig
Zero Pressure Drop Recorded Over Four Hour Holding Period Confirms Leak Absence
Standardized Step Up And Step Down Protocols Ensure Pipeline Structural Stability
