This product is a specialized tool designed for pipe welding. It assists welders in quickly completing tack welding preparation. It is suitable for precisely aligning and connecting pipe-to-pipe, pipe-to-elbow, and pipe-to-flange joints, ensuring coaxial alignment of the connected pieces. This guarantees roundness, gap consistency, and concentricity of the pipe ends meet welding requirements, preventing misalignment or uneven gaps that can compromise weld quality.
