Grace equipment in Vietnam: the TPS application

At Tien Phong South (TPS) in Vietnam, cooperation with Grace covers complete production lines and the replacement of existing European extrusion equipment. During 2025–2026, the customer placed orders for seven production lines and additional stand-alone equipment.

Positive feedback from operation

TPS has given positive feedback on the stable operation, output, melt temperature and energy consumption of Grace 40D extruders. Grace has also provided prompt, efficient aftersales support.

A specific pipe result, supported by process engineering

A Grace 1600 line producing 1200 mm SDR11 pipe recorded approximately 3.5% cross-sectional wall-thickness non-uniformity. Low-melt-temperature extrusion, die flow-channel design and internal die cooling work together to support melt condition, circumferential distribution and thermal management. A more even wall can create room to reduce unnecessary over-thickness while maintaining minimum-wall and quality requirements.

Non-uniformity = (maximum − minimum wall thickness in one cross-section) ÷ nominal wall thickness × 100%.

Cooperation extends to equipment replacement

TPS adopted Grace low-melt-temperature extruders to replace multiple existing German extruders. The 75 and 90 models used in this application cover maximum rated outputs of 1,200–1,600 kg/h.
