Foreword This British Standard was prepared under the authority of the Mechanical Engineering Industry Standards Committee and was first published in 1949. The present revision was undertaken to provide tank sizes in metric units and to cater in particular for plates which are now being supplied in metric thicknesses. It is pointed out however, that the sectional dimensions in this revision are interchangeable with the imperial imperial dimensions in the 1949 edition of the standard.

Sectional tanks provide a convenient means for the bulk storage of a variety of liquids not subject to pressure other than static head. As with all sectional assemblies, the components are readily transportable and, subject to unit multiples, can be erected to give varying proportions of length to breadth and depth. It is also possible, by arrangement between the purchaser and the manufacturer at the time of the enquiry and order, to make provision for future extension in capacity by increase in floor area or (within limits) depth. Tanks with internal flanges to the bottom are suitable for use where they are to be erected on a solid level floor or with internal flanges throughout where access to the exterior for erection is precluded by reasons of space inside a building. Tanks with external flanges are suitable for use where a plain internal surface is necessary, or where there are no restrictions as to external access or where the exterior of the tank is to be lagged. Pressed Pressed steel tanks tanks are not recommended recommended for for a depth greater greater than 4 880 mm. It is recommended that all pressed steel sectional tanks should be inspected inside inside and outside at intervals intervals not greater than than 12 months. At such periodic periodical al inspection, care should be taken to examine the stays, stay cleats, through bolts and nuts, ladders and the surfaces of the plates. Where there is excessive corrosion apparent the component affected should be replaced. Water and other liquids vary in their corrosive action on the inside of the tank. Corrosive action on the outside of the tank varies according to location and climatic and other conditions. It has not therefore been found practicable to specify appropriate internal or external coatings; these should be the subject of mutual arrangement between the purchaser and the manu facturer at the time of the enquiry and order. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

1 Scope This British Standard specifies requirements for pressed steel sectional rectangular tanks, working under a pressure not greater than the static head corresponding to the depth of the tank, built up of pressed pressed steel steel plates plates 1 220 mm square square used used to contain cold water, hot water, potable liquids, certain oils and chemicals. Tanks may b e constructed as follows: a) with external flanges; I S B ) c ( , y p o C d e l l o r t n o c n U , 4 0 0 2 h c r a M 3 2 , h g u o r o b h g u o L f o y t i s r e v i n U , r z v c o b l r z v c o b l : y p o C d e s n e c i L
b) with internal bottom flanges, ext ernal side and end flanges. Two types are specified: Type 1. With 1. With a combined double flange at an angl angle e of 45° and and 90° to the plane of the plate on all four sides as illustrated in Figure 1. The plates of type 1 tanks are hot pressed complete. Type 2. With 2. With a single single flange flange at an angle angle of 90° to the plane of the plate on each of two, three or four sides, depending on its position in the tank. Type 2 tanks are cold pressed as illustrated in Figure 2, with the flange corners welded. This standard does not provide for tanks subject to earth or other external pressure other than wind pressure. NOTE For an illustratio illustration n of a typical typical tank tank with with external external flanges see Figure 8. For approximate weights and full nominal capacities (without freeboard) of open top tanks see Table 1 to Table 4.
Tanks can also be assembled with all flanges internal with the addition of other components, but because of the difficulty of assembling and maintaining this type of tank they are n ot preferred. All tanks can be supplied with open or closed top. Information on erection and supports is also included.
2 References The titles of the British Stan dards referred to in this standard are listed on the inside back cover.
3 Information to be supplied with the enquiry and order The following information, as appropriate, should be supplied by the purchaser with his enquiry or order. a) Type of tank required (clause 1), type of cover (if any), number and position and type of manhole(s), number of divisions if required. b) Capacity required in litres or dimensions in millimetres millimetres in multiples multiples of 1 220 mm and whether any provision is to be made for future extension and if any level indicators are required.
