Special Applications for Piping Systems

New Technologies, New Products, New Applications # 2001 Munich

Topics concerning pure or further developed materials take priority within the framework of this event. This lecture treats the combination of different materials and the possibilities of creating out of them the optimal construction for the respective, individually defined case of application. Chemical, mechanical and environmentally technological aspects will be considered and integrated in long-term solutions guaranteeing a long-lived service in contact with dangerous liquids. The development of new production processes also requires the appropriate handling of the used liquids especially with regard to the environmental protection. Thermoplastics compete directly with the so-called classical materials and offer primarily practical advantages to the user because of their excellent corrosion resistance. In the following, two areas of application will be treated in more detail : Liner Constructions and Double Containment Piping Systems.

In recent years composite constructions in the field of chemical apparatus engineering and pipe construction have increasingly gained in importance. Composite constructions with inner liner materials are always used in cases where solid constructions with plastics, stainless steel or special metals are economically limited due to constructional features. In such cases the high chemical resistance of thermoplastics is combined with the mechanical resistance of well-tested materials, e.g. fibreglass reinforced plastics (GRP) and steel.

The chemical resistance of the lining material is one of the most important selection criteria for the inner lining material. Further information may be found in the SIMONA catalogue “Chemical resistance”, which is also available in a disc version.

The operative temperature range, the processing technique, the application in the field of food processing as well as possible thermal linear deformation are further selection criteria for inner lining materials.
