Long-bed lathe designed to handle lengthy oil field parts
The new SL-40L long-bed lathe is designed specifically to handle long parts, from oil field components to drive shafts to machinery rollers.

It's an extended version of the company's SL-40 turning center that provides a maximum cutting length of 80 in. (nearly twice that of the standard SL-40) and a maximum cutting diameter of 25.5 in.
In standard form, the machine features a 15 in. chuck and an A2-8 spindle nose that provides a bar capacity of 4.0 in. A 40 hp (peak) vector dual-drive system combines with a high-torque gearbox to yield 1,400 ft-lb of spindle torque for heavy cutting, and provides speeds to 2,400 rpm for finish work and high surface feed rates. On-the-fly wye-delta switching provides the high torque and wide constant-horsepower band necessary for constant surface speed cuts. One option includes a 55 hp vector dual drive spindle and a 12 hp, high-thrust Z-axis motor.
To accommodate large-diameter tubing, a big bore version of the SL-40L is also available. This option upgrades the machine to an A2-11 spindle nose and features a 6.75 in. through-bore (chuck, draw tube, and hydraulic coupling are not included).
To support extra-long parts through the bore, a rear chuck provision is available that allows an air chuck to be mounted to the rear of the spindle. An optional steady rest platform is also available to provide increased support for turning and boring long shafts. Hydraulic power for the steady rest is provided by the lathe, and the gripper (not supplied) is activated automatically via M code.
Other options include live tooling, full C axis, high-pressure coolant, a chip auger, and a tool-presetter system. Several control options are also available, including expanded program memory, Ethernet interface, user-definable macros, and the firm's conversational Visual Quick Code programming system.

Transducer pressure range field adjustable
A new line of transducers enables programmable adjustment of the pressure range in the field.
In addition, the new Series 740 transducers offer improved thermal compensation, increasing overall accuracy to as much as ±0.25% total error band (TEB) over the entire compensated temperature range of the transducers. The new transducers are suited for use where repeatable, precise measurement is needed.
The new series incorporates application specific integrated circuit (ASIC) technology that facilitates field reranging of the transducer output through the attached cable by a factor of up to 10:1, while minimizing the effect on total accuracy. The ability to rerange the unit in the field enables periodic adjustment of zero and span, if desired, as well as greater flexibility to inventory transducers locally.
Another feature of ASIC technology is the enhanced compensation of sensor errors over temperature. This increases overall accuracy of the transducer to ±0.25% TEB over the temperature range of up to –20° to +60° C. (–4° to +140° F.). The TEB specification alleviates the end user from having to combine multiple transducer error specifications to calculate total accuracy of the unit.
The new level transducers, housed in a rugged 316SS or titanium package, are suited for rigorous environments encountered in liquid level measurement. The Series is UL/CUL, FM, and CSA approved for installation in Class I, Div. 1, Groups A, B, C, and D; Class II, Div. 1, Groups E, F, and G; and Class III, Div. 1 hazardous locations.
Pressure ranges of the Series 740 are 0-5 psig through 0-100 psig, with intermediate ranges available to meet specific requirements. Transducers are available in vented and sealed gauge formats.

A new, free brochure highlights the Sulfur-Rite H2S removal system.
The process is appropriate for smaller operations with H2S loads of less than 400 lb/day.
Anaerobic, packaged systems are available for flows as great as 250 scfm; higher flows can be handled by the aerobic, packaged systems in the product line for flow pressure gas streams up to 2,500 scfm, and especially suited for vent gas from oil/gas production, chemical processing, and storage tanks.
Systems can be operated in parallel to handle flows of more than 2,500 scfm or this firm can custom design a unit for uses where flows exceed 2,500 scfm.
