Pitch Diameter Gages Tapered

Pitch Diameter Gages – Tapered

Pitch Diameter for Tapered Threads

Now, operators are able to inspect both new and used pipe threads using precision Pitch Diameter Gages that allow them to pinpoint early signs of stress, perform preventative maintenance, and extend the life of their drill string connections. By measuring the pitch diameters, the operators can directly control the connection’s size during manufacturing, as well as ensure that the thread cones go into interference properly when the connections are torqued together.

In the past, pitch diameter has been ignored as long as the ring or plug gage threaded to an acceptable standoff. Using a pin location profile (LPP) and a PD-8000-RSC Series gage or a box location profile (LPB) with an IT-5104-RSC provides you plenty of control. The process of locating and measuring the pitch diameter takes less than a minute. This minute of inspection quickly decides the difference between good quality and bad quality.

Pitch Diameter Location

For rotary shouldered connections, pitch diameter location templates locate the point on the connection where the pitch diameter is measured. When applied properly to the connection, the template’s special layout mark indicates the proper thread to measure the pitch diameter. A simple mark with a felt tip marking pen allows the operator or inspector to accurately position the gage and read a diameter. Please specify the threads per inch (TPI), taper per foot (TPF), and thread form when ordering. Custom profiles may be available.

Pitch Diameter

Internal (Box) Pitch Diameter

Gagemaker’s internal diameter and groove gages measure variation in internal bore diameters. Setting dimensions for the pitch diameter gages are provided by the TDWIN Taper software. Gages require setting with a standard or on a MIC TRAC™. Gages are shipped with two 0.144″ diameter contact points (T144) as standard, but other points may be substituted. Software, standards (see below), and additional contact points are sold separately.

1½” – 10” (38.1 mm – 254 mm)	4” (101.6 mm)	T144	Internal Pitch Diameter Gage for Tapered Threads	IT-5104-RSC

The ball pitch diameter gages indicate the pitch diameter size of the product’s external thread. The gages are adjustable within a size range and use interchangeable contact points to measure different pitch threads. Gages are shipped with two 0.144″ diameter contact points (T144) as standard, but other points may be substituted. Gages require setting with a standard or on a MIC TRAC™. Software, standards (see below), and additional contact points are sold separately.
