Frequently Asked Questions
What materials can be processed by this extrusion machine?
This machine is specifically designed for processing PE (Polyethylene) to produce high-quality HDPE jacket pipes for insulation purposes.
What is the diameter range for pipe production?
The standard production range is between 75mm and 1400mm. For spiral type insulation HDPE jacket machines, the maximum diameter can reach up to 2000mm.
What are the main advantages of the integrated production line?
It allows for continuous production of heat-isolated and anti-corrosion layers on steel pipes simultaneously, which significantly improves efficiency and reduces costs compared to separate processing.
Does the machine include surface treatment for the steel pipes?
Yes, the line features in-line ball blast, de-rusting, and antirust painting treatments to ensure the highest quality of the final insulated pipe.
Is the operation of the machine automated?
The system is fully automatic and computerized, featuring high-precision hydraulic deviation revising to maintain stability throughout the extrusion process.
What types of foaming platforms are available?
We offer two platform types: a non-bracket type and a with-bracket type that utilizes spacers, both working with high-pressure foaming technology for maximum efficiency.
