Yesha Engineering

The 3LPE Pipe Coating Extruder System is a fully engineered solution designed for high-performance application of the Three-Layer Polyethylene (3LPE) coating on steel pipelines ranging from small to large diameters. This system ensures exceptional corrosion protection, mechanical strength, and long-term durability for pipelines used in oil, gas, water, and industrial applications.

Our extruder system integrates advanced technology to deliver a uniform, high-adhesion polyethylene layer over epoxy-primed and adhesive-applied pipes. It is designed for continuous, uninterrupted production with precise temperature control, consistent melt flow, and accurate thickness distribution.

• High-Output Extruders: Specially designed for adhesive (copolymer) and polyethylene coating with stable melt flow, high output, and energy-efficient screw design.

• Accurate Temperature Control: Multi-zone digital temperature controllers ensure consistent polymer melting and prevent material degradation.

• Uniform Coating Thickness: Advanced die head design provides precise and even coating across the entire pipe circumference.

• Synchronised Line Speed: Integrated logic-controlled synchronization with conveyors, pipe rotators, and adhesive applicators.

• Robust Structural Design: Heavy-duty frame with shock-free operation for reliable performance in continuous production environments.

• User-Friendly Operation: Touchscreen HMI with PLC automation for easy monitoring, start/stop sequences, and recipe management.

• Safety & Maintenance: Equipped with temperature alarms, emergency stops, motor safety protections, and easy-access maintenance points.

• Pressing roller system : Pnuematic controlled silicon press the extruded sheet uniformly
