OCTG Production Line
Hydraulic Expander for OCTG Production Line
This hydraulic expander serves as core forming equipment for OCTG lines, expanding and calibrating seamless casing, tubing and drill pipes to eliminate ovality, wall thickness unevenness and dimensional errors. Featuring precise hydraulic drive and modular dies for even radial expansion, it fits carbon, alloy and high-strength steel, ensures stable dimension consistency, and aligns with downstream processes to satisfy API Spec 5CT requirements.
OCTG Production Line, Solid State HF Welder
High Efficiency Solid State HF Welder for OCTG Casing & Tubes,ERW Tube Solid State High Frequency Welding Machine
Our team could suppluy tailored solid-state HF induction welder adopts AC-DC-AC variable frequency structure with thyristor rectification and LC filtering. Modular parallel MOSFET inverters connect resonant circuits via isolation transformers for power convergence and impedance matching, equipped with fast overcurrent protection to ensure stable, safe welding operation.
