All About Heavy Profile Gauges - Definition, Sizes, and Uses

 This term – “profile gauge” – has many different meanings. Each of those meanings relates to a unique type of measuring instruments or tools. Which tools to be precise? The ones that deal with the contours of different surfaces. Through this blog, you will get to know about the three types of profile gauges that are most commonly used. Also, the basic information about all these types is included with their uses.

Types of Heavy Profile Gauges

The three key types of profile gauges that are usually sold as measurement tools by the suppliers are:

●        Surface Profile Gauges

●        Contour Profile Gauges

●        Thread Profile Gauges

Every gauge out of the three serves a unique purpose. Therefore, these gauges are not rightly interchangeable with each other.  In simple words, because their functions are different so any of them would not work well in another’s place. As such, each of the three heavy gauge profiles needs to be understood separately.

Surface Profile Gauges

Any surface that appears to be uniform and flat may not be perfectly flat in reality. Even most of the machined surfaces gone past surface finishing operations have fair chances of not being perfectly uniform.

This very condition might cause the surface coating to peel away early or fail to shield and provide protection. Hence, the machinery to measure as well as quantify a surface’s profile is holds great value for the production process. A surface profile gauge is an instrument with which such measurements can be taken.

The size of this gauge corresponds with the gauge range parameter. This gauge’s range, that is, the minimum to maximum value for which this gauge can evaluate readings is 0 – 1,000 μm.

Contour profile gauges

The second kind of profile gauges is known as contour profile gauges. This equipment consists of a sequence of plastic or steel pins or needles held together. The pins are fixed in a manner that they are parallel to one other. Also, they are securely placed inside of a frame.

These pins are capable of extending and retracting when they are pressed against an object’s contour. When that happens, it causes every pin to accurately align with the contour’s shape. This device is also known by the name shape duplicator. Its general size is 11cm x 10cm x 10cm.

The contour profile gauges measure and store complex shapes precisely. They complete the process much simply and fast than other devices. This is because the other methods usually include having a large number of individual measurements with the reference surfaces.

Thread Profile Gauges

The third type of profile gauges is called thread profile gauges. A thread profile gauge is used for quickly identifying and verifying the tapered threads’ types. These threads are used for tubing and casing. Also, they are used for line pipes, as stated in API specification standard 5B given by the American Petroleum Institute.

A thread profile gauge is generally used for performing inspections on thread forms. In addition, these gauges detect the defects such as stretched threads conditions, rolled over threads or chipped inserts. These gauges are made in several sizes that match with the standard thread forms.

DMSL is a leading company in India that produces and supplies cold formed metal sections. They take extra care of precision when it comes to the heavy gauge profiles and other manufacturing elements.
