Find pipe thread data on the data tables and explanations available on the website of the Plumbing Supply Group, LLC. The company provides data on male and female pipe threads and a glossary of commonly used pipe thread acronyms.
The Engineering ToolBox and Maryland Metrics are two organizations that have charts showing pipe thread sizes on their websites. Common American national standard pipe taper threads are the NPT and NPTF, says The Engineering ToolBox.
An American National standard taper pipe thread chart includes the nominal pipe size, outside diameter, threads per inch and the pitch of the thread. The chart on the Machining Products website also includes measures of the length and diameter for hand tight engagement, effective external thread, wr
The National Pipe Straight Mechanical thread chart provides the thread allowance, major diameter and pitch diameter of the external thread, as well as the minor diameter and pitch diameter of the internal thread for each of the nominal pipe size. It also lists the threads per inch.
National Pipe Thread Taper tap drill sizes range from 0.242 inches to 3.243 inches, but pipe thread tap drill sizes vary widely depending on the type of thread to be cut. Some common pipe thread tap drill sizes are 0.438, 0.562, and 1.156, 1.50 and 2.22 inches.
Gauge, when applied to sheet metal, is used to determine the thickness of a single piece of sheet metal, with lower numerical values indicative of increasing levels of thickness. There are a number of standard gauge measurements in use, each with slightly different standard thickness.
Size six ear gauges are considered to be larger than average. Most earlobes are initially pierced with an 18- or 20-gauge needle. Gauge sizes typically range between size 20 and 00, with 00 being the largest.
A pressure gauge allows a fluid to enter from the item or equipment being measured and reacts by moving a calibrated rod inside it. The pressure can be correctly read when the rod has moved to its maximum position.
Typical earrings are gauged at either 18 or 20, depending on the particular piece of jewelry. Although gauge sizes can be as small as 00, 18 and 20 are the most common for new piercings so that a large amount of flesh is not removed from the lobe at once.
Standard steel gauges range from gauge 3, which is 6.07 millimeters in thickness, to gauge 38, which is 0.015 millimeters in thickness. Engineering websites, including EngineersEdge.com, EngineersHandbook.com and SIMetric.co.uk provide online sheet steel gauges. These charts provide information abou
