Abstract
2. Elastomers A wide variety of elastomers, generally synthetic, are used in modern valves of the butterfly and diaphragm types with the dual function of lining/protecting internal metal surfaces in contact with the duty and providing the necessary interference for sealing. Without resorting to exotic and expensive metals of construction, even most aggressive services can be successfully handled by variation of elastomer type, while the particular compound is designed to still retain the physical characteristics necessary for optimum sealing. The number of permutations is thus large and indeed one manufacturer offers as many as 18 different resilient liner options. The main elastomer types are summarised:

Abstract
It is now widely accepted that where maximum long‐life protective treatment is required for structural steelwork, sprayed zinc or aluminium metal coatings, followed by an occlusive painting system (except in mild rural ambient conditions) are particularly suitable and can reduce considerably maintenance costs. Nevertheless failures do occasionally occur, and it is the purpose of this article to enquire into the causes of these failures and the steps that should be taken by the inspectorate to eliminate them.

Abstract
Summary This paper examines the function, protection and applications of complex components such as valves in off‐shore environments. Materials of Construction and the coating/lining techniques and procedures available to ensure acceptable function and protection are discussed, while the limitations of existing painting specifications from the point of view of the component manufacturer are emphasised. Off‐shore services utilising valves are summarised and the types of valves to be found in service on production platforms are indicated.

Abstract
Summary The variety of approaches used to combat corrosion and afford protection of structures and components are outlined. Factors governing selection so often favour combinations of traditional metal and modern polymeric coating or lining. Emphasis is placed on the vital importance of surface preparation and comprehensive specifications. In this context, the role of Specialist Painting Inspectors is outlined and their contribution to quality assurance and improved standards of workmanship is illustrated by reference to bridges, offshore platforms, telescopes and lined components. Future trends are indicated with emphasis on newer methods of surface preparation and protection.
Further exhibits will be previewed in the November issue
