Pipeline Induction Heat (PIH), on behalf of Kestrel Subsea (main contractors to Occidental Petroleum (Caledonia Ltd.), recently completed a contract to internally clean and coat 17.6 kilometres of 6in and 10in diameter pipes. These pipelines may carry a mix of crude oil and corrosive gas at elevated temperatures, and therefore were internally protected against corrosion. The project was the first of its kind in the North Sea and combined the application of a cold cure liquid epoxy paint with a novel PIH‐designed electrical heating system, which ensured that the entire 17.6 kilo‐metre length of pipeline was maintained at acceptable temperatures throughout the cleaning and coating operations. This not only aided chemical cleaning but also ensured a rapid and satisfactory cure for the coating.

The purpose of this paper is to develop a numerical model of a steam pipeline connecting a boiler with a turbine, with an insulated outer surface. The temperature distribution inside the pipeline wall was compared when was perfectly insulated and when used real insulation on the outside surface.

The transient temperature, pressure and velocity of steam in the pipeline were determined using a proposed numerical model with distributed parameters. To calculate the transient temperature of the steam and pipeline wall the finite volume method was used. The energy conservation equations were written for all control area around all the nodes. The heat balance equations are a system of first-order ordinary differential equations with respect to time. The Runge–Kutta method of the fourth-order was used to solve the system of ordinary differential equations of the first-order.

The temperature distribution in the pipeline wall and the temperature distribution in wall insulation were presented. Also, the temperature of the steam and pipeline wall as a function of insulation thickness was calculated. Based on the results obtained by the proposed numerical model, thermal stresses at the inner and outer surface of the component were determined. To assess the accuracy of the proposed model, the results were compared to the analytical solution for the steady state.

The paper presents the results obtained from calculations using a numerical model of the steam pipeline with the actual insulation on the outer surface.

Smiths Industries is to supply the head‐up display system for the Sea Harrier. The company will design, develop and make the electronic head‐up display and weapon aiming computer system for the latest version of the HS Harrier which will operate from Royal Navy ships.

Pipeline Induction Heat (PIH) Ltd. win major pipeline contract. Work has now begun on the prestigious Trans‐Mediterranean Gas Pipeline Project — from mainland Tunisia across the Mediterranean Sea to onshore Italy.

Queen's Award for Pipeline Induction Heat. Pipeline Induction Heat Ltd of High Wycombe has been honoured with the 1985 Queen's Award for Export Achievement. The award has been granted to P.I.H. in recognition of substantial achievement in exporting high technology pipeline equipment to markets throughout Europe, the Middle East, Far East and Australia.

Pipeline Induction Heat Ltd (PIH), Burnley — UK, has successfully completed a rehabilitation project for the British Pipeline Agency, UK. This work involved the internal cleaning and coating of a 36 metre diameter × 6 metre high semi‐buried aviation fuel tank. The tank was constructed approximately 50 years ago and has been in full service throughout this period.

Texas Eastern, PIH and BRIT in research contract. Pipeline Induction Heat, the specialist pipeline technology company based in High Wycombe, U.K. and Texas Eastern North Sea, Inc. the U.K. subsidiary of the Houston based oil company has signed a major pioneering research contract to develop advanced internal/external coating systems for the pipeline industry. It will be the first research and development contract in Britain to arise from the new criteria for North Sea oil companies laid down by the Department of Energy in the 9th Licencing round.

A large number of coatings have been described which serve very specific purposes. An example is a foam coating which may be applied by spraying, dipping, or other normal procedures. On curing, however, there is sufficient gas generation to foam the coating. A fine cellular structure results. The resulting layer is thick but light and has a very high strength‐to‐volume ratio as well as insulating properties [Downey Finishing Corp., 1629 S. 55th Ave., Cicero, IL 60650].
