Condenser, heat exchanger restoration system
New Shield/Seals help eliminate the need to replace condenser and heat exchanger tubes.
Shields are thin walled, metallic tube inserts made from durable alloys. They are sized to fit the damaged tube ends and are expanded-either mechanically or hydraulically-into the parent tubes.
The inserts, besides repairing tube-end erosion/corrosion, help restore tube-to-tubesheet hole integrity, permit proper mechanical cleaning, and in many cases restore leaking and plugged tubes to full operation. The thin wall construction, expansion, and ID chamfer eliminate the possibility of end-step erosion, the firm says.

On-line reliability data base
The first release of a new internet reliability data base system, OnStream 2.0, allows refining and chemical companies to benchmark their equipment maintenance and reliability costs on line against industry-wide averages. Performance indicators such as mean time between failure and rolling total maintenance cost can be computed and compared on almost anything from a single type of turbine to an entire processing site.
Using a secure data base with internet access, OnStream gathers data submitted by each subscriber, computes comprehensive performance indicators, and feeds the data base averages back to the member companies. Tight security procedures prevent anyone from seeing their competitor's raw data, putting to rest any fears of unfair advantage or industry collusion. Over time, continuing data submissions will continuously enhance the quality and reliability of the growing data base, the company notes.

Lubrication systems for heavy-duty applications
New API 610 and 614 lubrication systems provide customized reliability for heavy-duty centrifugal pump and compressor applications.
Reliability is built into these heavy-duty systems, the largest of which measure 11 ft by 40 ft. Each unit is built to requirements as set by individual applications and API standards. Made of high grade materials, every system is subjected to a variety of tests including operational, hydraulic, electrical, and functional. Reliability is thus verified prior to shipment, the company says.

New antifouling product to inhibit marine growth
Snokote AF is a new product that promises to inhibit growth of marine organisms, such as barnacles and algae.
It is suited for such applications as geophysical streamers and related equipment, mooring lines, channel markers, and buoys.
The semisynthetic, solid state hydrocarbon based compound is nontoxic, nonflammable, and contains no VOCs. It may be applied to any coated or uncoated surface, by brush or spray.

New 27/8 in. OD MWD system
The new Ultra-Lite 27/8 in. OD measurement while drilling system has been designed to provide efficient, cable free steering and logging in slim-hole reentry uses for jointed pipe and coiled tubing applications.
Reentry drilling from existing well bores can be achieved without the need for cutting and pulling of 41/2 in. casings and liners. The slim hole MWD when combined with slim OD directional drilling assemblies can be used to side-track directly from these well bores.
The tool incorporates the modular design and field proven sensors of existing equipment. These combined with the low power consumption, proprietary thread design, short tool length, and well site servicing capability help ensure flexibility in bottom hole assembly design, low cost utilization to meet requirements from short radius (>1°/ft) to more conventional requirements in the slim hole market.
