Choice of materials available to the gas industry

Author(s) : Thorne, Hall 1972 Southampton

Plastics pipes have been used for a variety of applications since the mid-1950s, but they have not been considered very seriously by the Gas Industry until fairly recently. Until 1965, the majority of fuel gas in the UK was 'towns gas' with a high content of liquid aromatic hydrocarbons. This 'wet' gas attacked pipes...

Design considerations for gravity sewers in PVC

Discussions

Author(s) : Case Studies 1972 Southampton

Chairman: Speakers have often mentioned the purpose and use of the products, and if I was speaking only from the building side I would say that perhaps in this day and age one needs to think of more than just current use. The environment, and the building environment particularly, is a complex thing. There are...

Education in plastics

Author(s) : Walker-Holmes 1972 Southampton

I propose to deal with this very wide subject in two stages: firstly, to discuss the ways in which it is possible to gain an education in plastics, and then to spend a short time considering whether or not this provides the right type of person for the plastics industry in general, and for those who make and use...

Hospital drainage - Sanitation and the use of plastics

Author(s) : Payne 1972 Southampton

There is nothing new about sanitation — it was discovered at ‘Skara Brae’ in the Orkneys that Neolithic stone huts were provided with crude drains leading from the recesses in the walls that are supposed to be latrines. One of the earliest known baths came from Crete and is dated about 1700 BC, some 3600 years...

Installation for plastics pipelines for effluent conveyance

Symposium Dinner

Author(s) : Catterick 1972 Southampton

Those materials such as plastics pipes and plastics articles which have a relatively low labour content must inevitably become more economical relative to their conventional rivals as inflation continues, and certainly this is a process which has been shown to be true over the past two years. The trend must continue,...

The acceptance and the place of plastics pipes in chemical process work

Author(s) : Meier 1972 Southampton
