August 2013 - The problem of quickly aligning a variety of different sizes of pipe with one clamp and, at the same time, having a sturdy tool that stands up to years of heavy field use has now been answered with the INT pipe alignment clamps. Many alignment tools are either poorly built or do not cover a useful range. Size specific clamps though heavy duty are not able to align elbows or flanges. With the INT Series of pipe alignment clamps a welder can invest in 3 clamps that cover a range of 3/4” to 12” pipe. With a heavy duty forged steel design and electroplating for rust and spatter resistance, they will last a lifetime. The three models are INT 1-3, INT 2-6 and INT 6-12 and cover the respective pipe sizes.
