“Rolling in Results” with the New Corrosion Mapping Scanning Solution from Sonatest Ltd.

Introducing the Veo & Corrosion WheelProbe Scanning System Building on the proven success of Corrosion WheelProbe a new semi-automated solution for corrosion mapping applications has been developed by Sonatest Ltd; the Veo & Corrosion WheelProbe (CWP) Scanning system. The CWP Scanner is a new enhancement in response to clients’ requests, providing an easier, semi-automated way of providing 100% coverage.

The system as a whole consists of the veo 16:64, a phased array flaw detector, a 64 element Corrosion WheelProbe and a CWP scanner. The Corrosion Wheel Probe is a tried and tested solution for corrosion mapping by many leading companies in the Pipeline and Oil & Gas sectors, hence the development of this system.

 The scan width of a Corrosion WheelProbe (CWP) is close to 50mm in one pass and it can be used on pipe diameters from 4 - 42 inches.  Importantly the conformable tyre allows excellent coupling to rough surfaces, and the design allows for consistent reliable inspection in both depth and amplitude. This amplitude mode enhances the possibility of finding small pit type defects, which normally do not give a good ultrasonic response, however results show excellent indications of internal condition. The CWP is fitted to an adjustable connector, equipped with a second encoder, which allows for multiple adjacent scans with a good overlap for complete coverage.

The distinct advantage of the CWP Scanning System is in the relative simplicity and complete autonomy from the need for additional power sources on the inspection site.  Ease of portability along with the speed of set-up and deployment is also a key advantage for the end user in the field.

This Veo & CWP scanning system additionally gives the flexibility of utilising the CWP on a completely manual basis for small area scans, such as for screening of pipe work of vessels (where LRUT has been used) or for (with certain limitations) scanning along the length (Axial) of the pipe.

The CWP Scanning System and accessories will be showing at the following UK shows; Offshore Europe 2011 Exhibition, 6-8 September, Aberdeen and at the Materials Testings Exhibition and Conference, 13-15 September, Telford.

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.
