TWO new transformer-oil tankers will shortly be going into service with the. Mobil Oil Co., ltd. They are articulated vehicles with Leyland Super Comet tractive units. The semi-trailers have Cranes running gear with air suspension, and tanks constructed by Yorkshire Engineering and Welding Co., Ltd. Stainless-steel plate has been used for the elliptical-section tanks to eliminate corrosion.
Each tank holds 2,500 gal., accommodated in three 500-gal, compartments and one 1.000-gal. compartment, all of which are fitted with silica-gel breath* equipment and conservator tanks. ' The silica-gel equipment, which is housed in the meter cabinet, prevents contamination of the transformer oil by removing the possibility of damp air being drawn into he compartments.
The conservator tanks housed on top of the main tank, each have a capacity of 16 gal. and ensure accurate filling of the compartments. Bottom loading is employed, and the outlet-pipe system is designed so that, by means of Exactor self-sealing couplings and flexible hoses, delivery to customers is carried out through a Drum cargo pump on the tractive unit. Delivery is measured by a Wayne flow meter.
