[Excellent Function]: The pipe center finder is designed to assist users in accurately locating the center of a pipe or cylindrical object. This tool uses visual alignment and precise measurements to determine the exact center point, supporting tasks such as drilling, welding, or installing fixtures onto the pipe. [Wide Application]: This tool is suitable for pipes with diameters ranging from 1-1/2 inches to 6 inches. It can be used to establish center lines, determine angles, mark butt joints, locate points inside pipes or tanks, align keyways, and calculate inclinations. Ideal for pipefitters and welders, it improves positioning accuracy and efficiency. [Easy to Use]: 1. Adjust the hexagonal nut using the included screwdriver. 2. Place the pipe center finder on the pipe and rotate to achieve the desired angle. (Ensure the bubble level is centered within the green indicator and level.) 3. Press the center column down to the fixed position. 4. Tap gently with a hammer to mark the center point on the pipe. [Durable Construction]: Made from high-quality metal materials, this tool is built for durability and long-term performance in demanding environments. [Adjustable Dial Bubble Protractor]: Features an adjustable dial bubble protractor for precise angle measurement and center column positioning.
