SAET INDUCTION
Introduction
Our dedicated Polyethylene (PET) coating system provides industry-leading protection for critical infrastructure in the Oil & Gas sector.
This advanced process is engineered to ensure long-term integrity for pipelines operating in challenging environments.
The Application Process
The coating is applied through a precision-controlled, multi-stage thermal process:
-Thermal Activation: the substrate surface is heated to a precise temperature of 270°C.
-Primer Application: a specialized primer is applied to the heated surface to ensure maximum adhesion.
-Extrusion Coating: a high-grade polyethylene film is extruded directly onto the surface, creating a seamless protective barrier.
This modern coating process is considered an gold standard for protecting tube surfaces against the primary causes of degradation

SAET PRODUCTS
Our comprehensive PET coating installation is a turnkey solution consisting of:
-Static Inverter Unit: for efficient power conversion
-Integrated Control Desk: providing a centralized interface for operators
-Custom Coil Set: optimized for specific pipe dimensions
-Pyrometric temperature Control: Ensuring real-time, high-precision thermal monitoring
-Closed-Circuit Cooling: a distilled water unit designed for consistent thermal management
Saet Emmedi Polyethylene Coating Equipment are highly proven solid state IGBT converters (inverter power over 2 Megawatt), which allow a consistent and proper heat treatment of the full body of the tube or pipe at the required temperature.
The temperature of the tube is controlled by an optical pyrometer targeting the tube surface between inductor and the coater.
Machine Features
– Power and operating frequencies optimized according to production requirements.
– IGBT based I-Power inverter working at proper frequency
– Inductors are coaxial to the pipe, multiturns, water-cooled inside with deionized water and the typical gap to the tube is 60 to 150mm on the radius.
– Pyrometer for temperature control.
