Title: Bruno J De Sivry: Innovator in Tubing and Electromagnetic Measurement

Introduction

Bruno J De Sivry is a renowned inventor based in Paris, France, holding an impressive portfolio of 15 patents. His contributions to the fields of welding and electromagnetic measurement have significantly advanced technological processes in the industry.

Latest Patents

Among his most recent innovations is an internal mandrel designed for the operation of butt joining two lengths of tubing. This sophisticated mandrel features longitudinally separated zones that match, weld, and check the welding, coupled with a displacement system allowing sequential presentation of these zones at a single working station. Additionally, he has developed an apparatus for electromagnetically measuring the ovalization of ferromagnetic pipes. This invention utilizes an electromagnetic pickup that travels in a circular path around the pipe, transmitting signals that reflect the radial distance between the pickup and the pipe. These measurements, compared with prior data, allow for accurate deductions of the pipe's transverse configuration.
