High performance plug valve
A new brochure, free upon request, describes the Durco Mach 1 high performance plug valve.
The nonlubricated quarter-turn valves are available in ASME Class 150, 300, and 600 (derated) flanged ends.
The valve lowers turning torques for reduced manual and automated actuation costs, the brochure says. Turning torques are unaffected by increases in line pressure, so turning torques are constant and predictable.
The Durco Mach 1 is designed with an ISO mounting pad. The expanded temperature coverage ranges from -20° F. (-29° C.) to +525° F. (274° C.) with excursions to 550° F. (288° C.).
The brochure notes that the valve's standard port seal seats or optional full sleeve incorporate fluorocarbon with high alloy substrates to permit higher temperature use and lower turning torque.

New turnkey drilling tool kit
Maurer Technology Inc. and Compaq Computer Corp., both of Houston, are offering a new turnkey drilling tool kit.
Maurer has configured the Compaq iPAQ Pocket PC with a software tool kit-the Driller's Toolkit-containing more than 100 drilling calculation tools.
About the size of a folded wallet, the iPAQ Pocket PC can be programmed with tools for performing calculations required in drilling mechanics, drilling hydraulics, drilling and completion, and directional drilling. The new technology allows oil field operators, engineers, well planners, and technicians to make complex calculations in seconds, using the industry's leading drilling calculation tools. The tool also provides e-mail capabilities, a calendar, contacts storage, Microsoft Word word processing, and Microsoft Excel spreadsheet software. Users can synchronize the iPAQ Pocket PC with a notebook or desktop computer to help ensure continuous access to current information and transmit data to other devices via an infrared port.
The user accesses the programs by pressing the display screen with a stylus. Because no keyboard is required, a worker can use the computer in almost any environment, without having to remove gloves or other protective gear. Using the stylus, the operator can enter data on an alphanumeric panel or on a sketch panel. The sketch panel allows the worker to write characters directly onto the screen and program the computer to recognize each handwritten entry. For added convenience, the user can store as many as 10 frequently used tools in a favorites menu for access with a single tap of the stylus.

Monitor detects corrosive conditions rapidly
The new environmental conditions monitor (ECM) multiparameter system measures humidity, temperature, and the corrosive attack on two replaceable thin-film sensors and shows the rate of corrosion on indicator lights corresponding to the ISA classification of environments for copper and silver.
ECM supports analog and digital outputs of information and provides remote alarming, display, and recording. This information can also be stored via the on-board data logger, and accessed through optional PC software.
The new monitor is particularly suited for environmental monitoring in refineries and chemical plants.

Low-sulfur benchtop analyzer for petrochemical uses
The XEPOS low-sulfur analyzer is designed to provide a detection limit of less than 1 ppm for sulfur in fuels.
Employing proprietary polarized excitation geometry, the analayzer offers a factor 10 improvement in sensitivity, the company says.
Simple to operate, the unit does not require specially trained operators, and the calibrations exhibit long term stability. The system requires virtually no maintenance and no special air conditioning.
Additionally, it features specially designed sample cups, eliminating the possibility of contamination or leakage. A sampling system allows safe sample input without having to shut down the x-ray source, saving time and helping ensure long term precision of results. The system is not influenced by differences in sample density and viscosity.
