Determine Pipe Thread Gauge Using a Screw Pitch
Gauge.
Introduction
Determining thread gauge of different equipment
like pipes, nuts, and bolts helps in proper
fitting, and in securing better connections. It
also helps in fabrication, or purchasing the
right parts for these pipes. This ensures better
functioning and optimum integration. When the
thread gauge is not calculated, and parts are fit
together, it could lead to many operational as
well as safety problems. A screw pitch gauge is
used to accurately measure the thread gauge.
Using it properly is extremely important to get
precise results. This will help in better and
tighter integration, resulting in longer service
lives of hardware.

1. Check the Measurement System on Screw Pitch
Gauge

• The marking system on the screw pitch gauge might
  be different from the one you generally use.
  Examine the markings on the gauge. The unit of
  measurement will be mentioned on the gauge
  itself. It should be compatible with the rest of
  your equipment and calculations.

2. Measure the Pitch of a Thread

• A gauge consists of several leaves with jaws that
  are used to fit into threads and measure the
  pitch. In order to measure the pitch, the
  subsequent steps should be followed
• Swing one of the leaves forward or unfold it.
• Place the toothed edge of the leaf onto the
  threaded portion. The serrations of the gauge
  should fit comfortably within the threads of the
  pipe. If they are too loose or too tight, try the
  other leaves.
• Continue this process until you find the exact
  fit.
• The measurement will be mentioned on the leaf of
  the gauge. This is your reading.

3. Measure a Known Size

• Choose a pipe with a known gauge. Repeat Step 2.
  On measurement of the pipe, you should get the
  same reading as that, which is provided by the
  manufacturer. This will help you practice and
  perfect the measurement technique.

Tips.

• For general applications, fine threads will be
  able to provide better integration compared to
  their coarser counterparts. On the other hand,
  coarser materials will provide a lasting and more
  secure connection when used in softer material.
• This method can be used to check the thread gauge
  of pipes, screws, nuts, and bolts.
• Storing the gauge correctly is important to
  increase its service life. Keeping it in good
  shape will help you get accurate results.
• The method of thread gauge calculation of metric
  and inch (English) threads is different. TPI
  (Teeth per Inch) is the measurement of threads of
  pipes that are manufactured using the English
  production method. Gauge of metric threads is
  calculated by measuring the distance between two
  threads. Please make a note of the make of your
  hardware and gauge, and proceed accordingly.
• Dont press the gauge into the threads with
  extreme force. Lightly holding it on the pipe or
  screw will help you get better results without
  damaging your equipment.

Warnings

• When working with pipes, screws, bolts, and other
  equipment, it is important to wear appropriate
  safety gear and carry the right equipment.
• Ensure that your work processes conform to the
  rules set by your local safety authorities.
