Types of calipers (digital, dial, vernier)
Calipers offer a high degree of accuracy when measuring copper pipes. There are three main types:
Digital calipers: Provide a digital readout, making them easy to read.
Dial calipers: Use a dial to display measurements.
Vernier calipers: Require manual reading of scales but offer high precision.
Step-by-step guide to using calipers
Using calipers to measure copper pipe size accurately involves several steps:
Zero the calipers: Ensure the calipers read zero when fully closed.
Open the jaws: Adjust the jaws to fit around the pipe's outer diameter.
Close gently: Bring the jaws together until they just touch the pipe.
Read the measurement: For digital calipers, read the display. For dial and vernier calipers, read the scale.
Repeat for accuracy: Measure multiple times to confirm consistency.
Pipe Sizing Charts
How to read and use a pipe sizing chart
Pipe sizing charts are essential for converting measurements into standard pipe sizes. To use a chart:
Locate the measurement: Find the measured diameter on the chart.
Match to nominal size: Identify the corresponding nominal pipe size.
Verify compatibility: Ensure the selected size matches the required fittings and components.
