Forged Design Ensures Compliance Around the Globe

That is where John Crane Indufil can simplify your process as your one-stop resource for filtration products. All Indufil filters have a forged body construction, providing a compact weld-free design that complies with all international pressure vessel design codes, without the necessity for detailed weld certification.


“By eliminating the cumbersome testing process associated with welding specifications,” said Brian R. Adamson, North American Sales Manager for Indufil Products, “time and labor savings are built in. Further, our high performance forging process ensures that Indufil filters meet any design code or specification around the world, including API 614 as a minimum.”

Using a forged process as compared to welding has other benefits as well including elimination of rust points and weld imperfections. John Crane Indufil manufacturers numerous components for the filters in-house, eliminating unnecessary steps and dependence on outside vendors.

Perfect sealing is achieved via an O-ring and back-up ring arrangement, alleviating any issues with gasket bolting forces and potential leakage. Each Indufil filter can be configured as required with associated vents/drains, valving/porting, flanges and fittings to suit every application.

Approved to meet all major international design codes including ASME Section VIII, Division 1 in the United States, John Crane Indufil filtration products have double-seal connections, long studs for extra safe operation and a bolted top cover (no screwed connection). “John Crane’s acquisition of Indufil in 2008 has been extremely beneficial to our customers as we offer the widest variety of seals, bearings and filters for the turbomachinery industry,” said Jeroen Huizinga, Sales & Marketing Manager.

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.
