Rotork Valve Actuators Utilised In LNG Project

Fluid power valve actuators from Rotork have been installed throughout a liquefied natural gas importing and distribution project that is expected to meet 40 per cent of the demand for gas in Chile. The liquefied natural gas (LNG) complex at Quintero Bay encompasses the installation of a sea terminal to receive LNG from tankers and a plant for regassifying and distribution by pipelines into central Chile.

Rotork Fluid Systems has received orders for heavy duty, scotch-yoke pneumatic, gas-over-oil and high-pressure gas actuators, which have been supplied to valve-makers in France, Italy and Spain. The majority of the 87 CP and GP range pneumatic actuators supplied are operating cryogenic service ball and butterfly valves at the Quintero Bay marine terminal and the adjacent storage and regassification plant. The GO range of gas-over-oil and HPG range of high-pressure gas actuators have been supplied for a 28km pipeline that links the Quintero LNG complex to the Electrogas terminal at Quillota for integration with the existing gas network and fuelling combined cycle power plants operated by Endesa Chile.

The GO unit is installed on a Class 600 24in ball valve at the City Gate in the Quintero LNG terminal, while the HPGs are installed on Class 600 8in and Class 300 12in ball valves at the Electrogas Plant Gate in Quillota. Designed for safety and shutdown duties, GO and HPG actuators use the pipeline gas at the motive power source. Valve operating speed is adjustable in both directions and manual hydraulic override is provided as standard.

All the Rotork actuators supplied are certified to Atex 94/9/EC and IP66M/67M in accordance with PED 93/27/EC. The sales and engineering participation of Ineco, Rotork's local representative in Chile, has been a key factor in the company's success with this project. Rotork's activity was co-ordinated at Rotork's US head office in Rochester and involved Rotork offices in France, Italy, Spain and the UK, where the engineering, procurement and construction contractor CB and I is headquartered.

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.
