Thread type standard

This specification covers four specific types of plain end or threaded and coupled carbon steel pipe for use in water wells. The values stated in either inch-pound units or in SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values in each system are not exact equivalents; therefore, each system is to be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.

At Trimantec, our sales department gets a number of questions regarding technical specs for industrial parts. One of the concepts that seems to stump a lot of people is port threads. While we already have an in-depth blog post that walks users through the process of identifying threads.

Gate valves are classified as either rising stem or nonrising stem valves. For the nonrising stem gate valve, the stem is threaded on the lower end into the gate. As the hand wheel on the stem is rotated, the gate travels up or down the stem on the threads while the stem remains vertically stationary. This type valve will almost always have a pointer-type indicator threaded onto the upper end of the stem to indicate valve position. Figures 2 and 3 illustrate rising-stem gate valves and nonrising stem gate valves.

Bolts, screws and studs are the most common types of threaded fasteners. They are used in both permanent or removable joints. Bolts: They are basically threaded fasteners normally used with nuts. Screws: They engage either with a preformed or a self made internal threads. Studs: They are externally threaded headless fasteners. One end usually meets a tapped component and the other with a standard nut.
