FAQ

• What exactly does the PN16 pressure rating signify in practical applications?

  The PN16 designation indicates that the coupler is structurally engineered to sustain a continuous working pressure of 16 bar (approximately 232 psi) at a standard operating temperature of 20°C. This makes it exceptionally well-suited for high-demand environments, such as municipal water mains and industrial fluid transport, where maintaining high pressure is critical for system efficiency.

• How does this coupler perform when subjected to severe water hammer effects?

  Thanks to the viscoelastic properties of the virgin PE100 material, the coupler possesses remarkable dynamic stress absorption capabilities. It is designed to safely absorb and dissipate transient pressure surges and water hammer shocks up to 25 bar. This flexibility prevents the joint from fracturing, thereby protecting the entire pipeline network from sudden pressure spikes.

• Can this fitting be used to connect pipes with different Standard Dimension Ratios (SDR)?

  Yes, the coupler is highly versatile and engineered for cross-compatibility. It seamlessly accommodates standard SDR variations, allowing you to securely connect SDR 11 (PN16), SDR 17 (PN10), and SDR 21 (PN6) pipes. This adaptability is particularly beneficial during complex system retrofits or when integrating new high-pressure lines into existing infrastructure.

• What makes this coupler suitable for above-ground, exposed installations?

  The raw PE100 polymer is specially compounded with a 2.5% carbon black additive during the manufacturing process. This specific formulation acts as a powerful UV shield, preventing the molecular degradation and embrittlement typically caused by prolonged exposure to direct sunlight. Consequently, it guarantees a lifespan of over 50 years even in harsh, above-ground environments.

• What quality assurance processes are implemented before the product leaves the facility?

  As a dedicated manufacturer, we enforce a strict, multi-tiered quality control regime. Prior to dispatch, products undergo comprehensive hydrostatic pressure testing, Melt Flow Index (MFI) analysis, and tensile strength evaluations. Furthermore, every unit features barcode traceability, ensuring that its manufacturing parameters and material origins can be fully tracked, guaranteeing industrial-grade reliability.
