Coupling starter/screw-on systems for OCTG

PMC-Colinet, a division of Ajax Tocco Magnethermic Corp, is the manufacturer of advanced coupling starter and screw-on machine systems for secure connections in the oilfield. Designed for API and premium connections, these systems use floating spindles to automatically and precisely fit a coupling onto a pipe end for OCTG applications. The systems have a high-powered motor to screw the coupling on securely, applying and recording the right torque. These systems save time, labour and expense in the customer’s application by giving a tight and precise pipe-to-coupling fit – a must for productive execution in the field. The coupling starter and screw-on machines assure connections for pipe sizes ranging from 1.9" up to 20". The systems are equipped to measure and control

torque, turns, stand-off and ‘J’ dimension metrics. Accompanying operator interface terminals display and store final values and graphical profiles, using PC-based Windows operating systems. Other technical features include a coupling starter, independently controlled spindle speed, and a hydraulically actuated gripper head and pipe chuck. The coupling screw- on has a variable spindle speed, 75kW (100hp) spindle motor power, and a make- up torque of up to 35,000ft-lbs. The starter and screw-on systems are among the dozens of pipe-processing systems manufactured by PMC-Colinet. PMC-Colinet’s parent company, Ajax Tocco Magnethermic, is a leading worldwide designer and builder of heating, melting and processing equipment for pipe applications.

Multichannel tube wall thickness measuring system for PQF mill

Vallourec & Sumitomo Tubos do Brasil Ltda (VSB) has contracted IMS Messsysteme GmbH to deliver a multichannel tube wall thickness measuring system. This system, to be installed behind the PQF extractor mill, will be used to measure tube shells at the exit of its SMS Meer PQF mill.

From hacksaws to bandsaws

In addition to the estab- lished 13-channel measuring geometry for PQF mills, which is used for continuous measurement of polygonal wall distributions, the measuring system will be equipped with a high- resolution diameter gauge. A total of 18 laser triangulation sensors will be fitted, which will enable accurate detection of out-of-round flaws and profiling of the tube outside diameter.

The Hermann Klaeger Company, Germany, is the manufacturer of hacksaw machines, pipe bending machines, and bandsaw machines. Established in 1928, the company has sold over 135,000 machines to date. The company’s range includes band saws with a capacity from Ø 220 to 325mm round, fully automatic bandsaws, fully automatic twin-pillar bandsaws, vertical bandsaw machines, hacksaws (capacity from Ø 200 to 315mm round), ring rollers (universal bending machine, capacity pipe maximum Ø 70), and press benders for pipes up to 2" (available in hydraulic and electro hydraulic versions). The company sells its machines both to dealers and directly to the end user, and its products are specified in the catalogues of well-known dealers in Germany and other countries.

 IMS Messsysteme has been contracted to supply a new measuring system to VSB

The laser-based measuring technology, integrated for the first time in an IMS tube wall thickness measuring system, has already been used successfully for several years at Ovako Steel AB, Sweden, as a standalone measuring system. The sensor and analysis systems are now being integrated in the IMS measuring system in close cooperation with the company LIMAB. The system can simultaneously measure the wall thickness and eccentricity, outside diameter and profile, temperature and length of tubes in a single compact gauge, avoiding the need to install multiple individual systems.
