Hydraulic / Pneumatic Wedge Mandrel Powered / Non Powered
(Copyrighted product design (Hydraulic Wedge Mandrel) – No. – A-113607/2015)
Product Description
The Hydraulic Wedge Mandrel is a high-performance internal pipe alignment and clamping tool designed for precise positioning, expanding, and securing of large-diameter pipes during welding, fabrication, and pipeline construction. Powered by a hydraulic system, the mandrel uses wedge-type expansion segments to generate uniform radial pressure inside the pipe, ensuring accurate alignment, excellent stability, and consistent root gap throughout the welding process.
Manufactured from high-strength alloy steel and equipped with precision-engineered hydraulic components, the Hydraulic Wedge Mandrel delivers exceptional durability, reliability, and long service life in demanding industrial environments. Its robust wedge mechanism provides superior gripping force, making it ideal for heavy-wall and large-diameter pipelines where accurate alignment is critical.
The Hydraulic Wedge Mandrel significantly improves weld quality by minimizing pipe misalignment, reducing distortion, and ensuring consistent joint preparation. It is widely used in oil & gas pipeline construction, petrochemical plants, refineries, offshore projects, power generation, water transmission systems, and heavy engineering industries.
