Abstract

One of the fundamentals of cathodic protection is that a steel structure immersed in an electrolite is protected from corrosion if its potential with reference to a copper cell is −0.85 V or less (in the negative sense). Another fundamental of cathodic protection is that, to obtain correct results, the reference cell should be as close to the cathode as possible. For pipeline corrosion surveys and maintenance this condition means that the cell will be placed over the pipeline, the distance from the cell to the pipeline then depending on the pipe depth. The question is therefore raised: is −0.85 V the correct protection value when the reference cell is on the surface over the pipeline but perhaps 3 ft away from it?

Abstract

7. The cowsheds in Denmark are very similar in design to the more modern cowsheds in this country. They are, however, in general structurally superior to the average English cowshed and even to the Dutch cowsheds. In Denmark the flooring, standings, mangers, water supply, electric lighting, drainage from the cowsheds and devices for securing the cows are similar to what we observed in Nederland and equally satisfactory, but the Danish cowsheds were superior in respect of air space, windows and ventilation. In all the cowsheds which we visited the ceilings were high, the air space was ample, lighting by means of windows was good and adequate, cross ventilation was invariably provided. The gutters in Danish sheds are, however, much shallower than those in Dutch sheds, and are consequently not so effective, though movement of the cows is easier and safer.

Abstract

WE write on the eve of an Annual Meeting of the Library Association. We expect many interesting things from it, for although it is not the first meeting under the new constitution, it is the first in which all the sections will be actively engaged. From a membership of eight hundred in 1927 we are, in 1930, within measurable distance of a membership of three thousand; and, although we have not reached that figure by a few hundreds—and those few will be the most difficult to obtain quickly—this is a really memorable achievement. There are certain necessary results of the Association's expansion. In the former days it was possible for every member, if he desired, to attend all the meetings; today parallel meetings are necessary in order to represent all interests, and members must make a selection amongst the good things offered. Large meetings are not entirely desirable; discussion of any effective sort is impossible in them; and the speakers are usually those who always speak, and who possess more nerve than the rest of us. This does not mean that they are not worth a hearing. Nevertheless, seeing that at least 1,000 will be at Cambridge, small sectional meetings in which no one who has anything to say need be afraid of saying it, are an ideal to which we are forced by the growth of our numbers.

Abstract

Modern high pressure cross country gas and oil pipelines have two main forms of defence against damage. Constant and vigilant patrolling, generally by air, supplemented by foot and the standard well known corrosion defence of a good coating supplemented by cathodic protection.

Abstract

ONE OF the nightmares for the corrosion engineer applying cathodic protection to a jointed pipeline is the problem of the missed coupling, or severed coupling. For cathodic protection purposes the cathode has to be electrically continuous, which means that some types of mechanical joints which rely on joints for sealing which are electrically non‐conductive have to be made electrically continuous. This is done by means of a bond strap. The attachment can be by either:—

Abstract

There are three reasons for installing a deep hole groundbed by which it is meant inserting power impressed anodes at a depth greater than 50 ft. The three reasons are:— 1. To minimise interference problems. 2. To circumvent the problem of high surface soil resistivities. 3. To overcome wayleave difficulties. This account is concerned with 1 above.
