Site installation
Tank erection
Horseley Bridge Tanks provides a full UK tank erection service. Each site is inspected by a qualified supervisor prior to tank erection ensuring site and base suitability. An experienced team will build your tank and leave it ready for commissioning. Supervisors may also be provided for overseas contracts. Customers should, however, observe the following check points before calling HB to site:
Tank supports
Externally flanged tanks at ground/floor level require dwarf walls or piers, made of steel univeral beams, brick or concrete, with footings suitable for the bearing capacity of the sub-soil. The walls should be at least 500mm high and must run in one direction only with centres at 1000mm or 1220mm depending on the plate dimensions. They should extend at least 150mm beyond the tank at each end.
Dwarf walls should be between 150 and 225mm wide and should taper to no more than 110mm at the top to give access for spanners when bolting the bottom joints.
Supports for tanks 3660+mm deep require steel capping flats under the bottom flanges to give a greater bearing surface. Alternatively, steel supports may be used, in which case customers are advised to consult HB engineers regarding their design.
Access
To allow access to bolts, a clearance of 500mm should be provided all round the tank. When tanks are fitted with covers, a distance of 750mm should be left between the cover and any ceiling to allow access to the manhole. It is the customer’s responsibility to ensure adequate clearance around the tank.
Health and safety
HB reserves the right to refuse to carry out work in unsafe conditions. Erectors will observe site safety rules under relevant national and local health and safety regulations.
Delays
HB reserves the right to make additional charges for delays caused by preparatory work not being completed in accordance with its requirements.
