Vietnamese company installs the first 2,000 mm pipe extrusion line in Vietnam

Tien Phong Plastic Joint Stock Co. (Haiphong, Vietnam) will be the first pipe manufacturer in Vietnam to produce large PE pipes with external diameters of up to 2,000 mm. The company ordered a complete pipe extrusion line, which is to be delivered in spring 2015 from battenfeld-cincinnati. In 2011, Tien Phong had already decided to acquire a turnkey PE pipe extrusion line, including a die with an innovative cooling system. This equipment served the company well and as a result, the customer chose a die with internal cooling again this time.

The state-owned company Tien Phong ranks among the leading Vietnamese producers of pipes and fittings made of u-PVC, HDPE and PP-R. "Our pipes are manufactured to international standards, which is why we pay special attention to the quality of our production lines. We are already operating several lines from battenfeld-cincinnati and are particularly pleased about the material and energy-saving operation of this equipment and its easy handling," said Nguyen Quoc Truong, Tien Phong's General Director.

The core components of the complete line ordered most recently for the production of pipes with dimensions ranging from 630 to 2,000 mm are a solEX single screw extruder and a helix VSI-T+ pipe die. In addition, an EAC Drying System has been installed. It uses heated air from the internal pipe cooling in the die to dry raw material, thus saving energy, according to the company. High-performance extruders from the solEX series are particularly recommended for the production of HDPE and PP pipes. With their processing length of 40 D, they offer extremely high throughput rates with optimal melt homogeneity and low melt temperatures. The AC motors built in as standard ensure low energy consumption. In the line for Tien Phong, a solEX 120 is integrated, which manages an output of up to 2,200 kg/h with only modest space requirements.

Another contribution to minimizing space requirements is made by the helix 2000 VSI-T+ pipe die, which operates with active intensive melt cooling in addition to an internal cooling system, and with the two-step distribution concept consisting of a spiral mandrel distributor and a lattice basket, which is said to guarantee best possible distribution, homogenization and throughput with low pressure build-up. The efficient cooling system reduces sagging, which is of vital importance especially in the production of thick-walled pipes. Consequently, high product quality is ensured. At the same time, the intensive cooling system permits significant shortening of the complete line, which, in turn, reduces space requirements and makes the line particularly cost-efficient.
