This new ultraslim line Monoflange primary isolation ball valve is designed for instrumentation pressure tapping duties. The unit is suited for petrochemical uses where space and weight savings are crucial considerations.

It features an integral forged body with a single superfinished quarter turn ball valve to reduce operating torque and wear. The ball is vented for upstream cavity relief and to provide unidirectional capability. A choice of soft seats is available, including PTFE, Peek, and Devlon V. The unit also features a one piece stem spindle for antiblowout protection.

To minimize overall profile, the Monoflange is designed to be directly bolted to the vessel, process pipe, or orifice carrier. Supplied as standard with a flanged inlet and threaded NPT outlet, the unit enables direct mounting of the pressure measurement instrumentation, or remote mounting using impulse tubing.

The unit can also be supplied with a flanged inlet and outlet, which enables the mounting of flanged instruments, or blind flanged for use in venting and drain service. For added security, optional integral stud mounting bolts prevent disassembly of the valve body inlet from the vessel when removing the flanged instrument on the outlet connection. A range of options, including a 360

WFCalc, a new Windows software package, helps make it quick and simple for process plant engineers and designers to predict vortex shedding (wake frequency) problems with thermowells.

Supplied on a CD, the win 95/98/NT compatible software package encapsulates over 30 years of experience in applying the accepted international standards and the menu driven user interface prompts for all the data required. The package handles parallel and ASME Power Test Code 19.3 tapered thermowells and includes an extensive drop down menu of materials including most common and many exotic materials. Tools to convert from mass or volumetric flow to velocity and a comprehensive help file all contribute to making WFCalc exceptionally user friendly. Results can be printed or saved to disk for future reference.

Integrated geophysical suites

Enhanced product suites for seismic data analysis (Echos 99), for interpretation and earth modeling (Ergos 99), and for reservoir characterization (Poros) are on the market.

The Echos suite of seismic data analysis products features enhanced productivity through seamless workflows, offering interpretive options using a shared earth model. The system is open for user or site customization, and the new Echos 2000 version will share a common file system to minimize data duplication.

The Ergos suite of interpretation and earth modeling products offers a solution from data to decision-making, with fast, intuitive, proved technology that is compatible across the full range of operating systems, from Unix to the new, high performance Windows NT. The Windows NT-based Ergos demonstrates a complete interpretation work flow incorporating products lines of GeoLog, SeisX, and VoxelGeo using a shared earth model.

The new reservoir characterization product suite-Poros-helps professionals build geologic models from seismic data attributes, using a shared earth model for macro and microreservoir property description.

New BOP protector

A new blowout preventer protector is designed to seal at the bit guide.

The tool is easy to install onto BOPs or valves, the company says. The tool can be left on for stage frac work because all packers, plugs, and perforation guns can be run through the tool with no restriction, even with frac lines hooked up. Tubing strings can also be run through the tool, thus enabling the operator to use dead strings to monitor downhole conditions while fracturing down the annulus.
