Baker Hughes Selects Yorky Oilfield Grinder

Broadbent Stanley and the GAC Group have delivered their fifth Yorky Type 'O' oilfield grinder following their purchase of the machine's design and manufacturing rights. The latest order was received from the Baker Hughes Group for the installation at the Baker Oil Tools, Baku facility in Azerbaijan.

Arthur Mowat from Mobar, a machine tool sales and service specialist, said Baker Hughes approached the company initially on a consultancy basis to locate an oilfield grinder for them. Mowat contacted a number of companies, including Broadbent Stanley to evaluate their products. It became apparent that Broadbent Stanley's Yorky grinding machine was the most suitable for the job; it was said to be the only purpose-designed, heavy duty machine with a hollow spindle and traversing wheelhead, rather than the traversing table type.

Available in manual, semi-automatic or full CNC guise, it was specially designed to accommodate all oilfield grinding applications from casings to stabilisers, drill heads and hydroclean bars, along with all types of mills, reamers and fishing tools. As the Baku facility applications are mainly for 'one-off' fishing tools, the manual version was deemed ideal.

Optional equipment included an internal attachment for grinding the fishing tool bores and a series of quills to grind from 1-6in, in inch increments. The Yorky has a 44in (1118mm) swing over the slides with 120in (3048mm) between centres with the hollow spindle diameter of 12.2in (310mm). Maximum component length is 472in (12m) with a weight of 11000lb (5000kg).

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
