Bevel Measurement Tool

The Bevel Measurement Tool provides a consistent and accurate method of measuring the three key features of a J-prep bevel at the push of a button.

Key features

  • Contact based measurement of J-prep bevels

  • Three micrometers measure the land thickness and depth as well as bevel angle

  • Hardened wear surfaces for industrial use

  • Adjustable for different pipe sizes and guide to ensure correct alignment

  • Adjustable multi station spirit level to guide to 2, 4 or 8 different angles

  • Data is logged to a PC which displays go/no-go

Background

Our first tool had the same characteristics as the current tool which is now in it’s third generation. That is three calibrated dial gauges to measure all three characteristics required. As any welder will know, the control of the bevel is the starting point for a good weld. If the land thickness is too small there is potential for burn through and if it is too large there may be a lack of penetration.

Why?

A critical element in the successful welding of pipes is the composite profile of the end of the pipe or the bevel for short. A common bevel profile for mechanised welding is the J-prep profile which consists of a land a radius and an angled bevel. The dimensions of the land and it’s depth have to be within a specified tight tolerance as does the angle of the bevel.

How?

The Bevel Measurement Tool provides a consistent and accurate method of measuring the three key features of a J-prep bevel at a single the push of a button. This data can be used with wall thickness data to automatically yield the half-opening dimension.

The tool uses accurate dial gauges to perform the measurements. The measurements are logged on a computer in a customer friendly report which enables the bevel stage to be documented for quality assurance (QA) purposes. The Bevel Measurement Tool is designed to accommodate a wide range of J-prep bevel geometries, wall thicknesses and pipe sizes and can be verified for correct operation in the field, using a simple calibration block.
