Affordable HDPE Machine Prices for Composite Pipe Production Lines

PE100RC material provides superior slow crack growth resistance with minimum required strength (MRS) of 10MPa according to ISO 9080. Our production lines maintain ±1.5% dimensional accuracy for consistent wall thickness critical for gas applications. [Journal of Pipeline Engineering, Vol 21]

Our machines maintain 55±2° winding angles optimized through FEA analysis, balancing hoop and axial stresses per ISO 14692. Smaller angles increase axial strength but reduce pressure resistance.

Dongchai systems maintain extrusion temperatures within ±2°C of setpoints (typically 200-220°C for HDPE) using PLC-controlled 7-zone barrel heaters and PID algorithms.

In-line monitoring includes: wall thickness measurement (laser micrometer ±0.01mm), ovality detection (±0.5% tolerance), and automated hydrostatic testing at 1.5x operating pressure per ASTM D1599.

Our DCX-series lines deliver 150-800kg/hr outputs depending on pipe diameter and reinforcement configuration. Typical energy consumption is 0.35-0.5kWh/kg at rated capacity.

Using ASME PCC-2 methodology with our proprietary software calculating tape tension/winding patterns for target reinforcement percentages between 15-40% depending on service conditions.

Compliance with ISO 21003 (multilayer systems), API 15LR (reinforced thermosetting resin), and ASTM F714 (PE pipe dimensions) is maintained through integrated QA processes.
