OVERVIEW & ADVANTAGES

Product Engineering Highlights & Structural Design

100% Virgin Resins

Direct supply from Borealis, SABIC, and Sinopec. Absolutely zero recycled regrind or calcium fillers, guaranteeing maximum tensile elasticity.

Ultrasonic Wall Control

Automated KraussMaffei lines with 360° online ultrasonic thickness gauges ensure strict wall roundness and continuous dimensional precision.

Homogeneous Fusion

Thermal fusion melts molecular chains into a monolithic joint with zero mechanical weak points, eliminating risk of leakage for 50 years.

Ultra-Smooth Hydraulic Bore

Absolute roughness k=0.007mm minimizes flow friction and prevents scale deposition, boosting fluid energy efficiency over the entire lifecycle.

System Overview: Precision co-extruded five-layer structure with Kuraray EVOH barrier sandwiched between inner and outer PE-RT Type II polymer layers. Prevents oxygen diffusion into heating circuits (permeability <0.10 g/(m³·d)), safeguarding boilers, valves, and heat exchangers.

Turnkey Engineering & Complete Fittings Compatibility:

Full Range of Molded Fittings: Equal tees, reducing tees, 90°/45° elbows, end caps, and custom manifold headers.
Premium HPb59-1 Brass Threaded Inserts: Precision CNC-machined dezincification-resistant brass with anti-rotation locking grooves to eliminate thermal creep leakage.
Drinking Water Hygiene Certification: Compliant with German DVGW, NSF/ANSI 61, and WRAS health requirements for human potable water.

INSTALLATION GUIDE

Standard Operating Procedures & Jointing Protocol

STEP 1

Square Cut & Deburr

Cut pipe perpendicular to the axis with a dedicated rotary pipe cutter; clean burrs completely.

→

STEP 2

Mark Insertion Depth

Mark fusion depth using a depth gauge to avoid over-insertion and internal flow restriction.

→

STEP 3

Uniform Heat & Push

Heat simultaneously on 260°C die without rotation; join axially within the specified insertion window.

→

STEP 4

Cooling & Pressure Test

Allow natural cooling without stress; conduct hydrostatic pressure acceptance test at 1.5× design pressure.

FACTORY QUALITY ASSURANCE

CNAS Accredited Laboratory Inspection Standards

1. Hydrostatic Pressure Burst Test

Subjected to 1.5× nominal design stress at 95°C water bath for 1,000 hours with zero burst or leakage.

2. Charpy Impact Resistance at 0°C

2-hour freezing bath immersion followed by 2-meter heavy falling striker impact; zero shatter or micro-cracks.

3. Melt Mass-Flow Rate (MFR) Testing

Extruded samples verified against incoming raw material granules to ensure no thermal degradation occurred.

4. Longitudinal Reversion & Ring Stiffness

110°C thermal oven exposure testing verifies longitudinal deformation <2%; burial stiffness fully compliant.
