In many instances, cleaning aboveground storage tanks is complicated by the fact that high sludge levels prevent the removal of manway covers, or the lowering of product levels, due to potential damage to the floating roof.
The ATC Lance, Together with the cold tap manway, allow for a safe and effective procedure to reduce sludge volumes, so manways can be removed safely.
The patented design of the DS Articulating Lance allows for complete rotational direction flow of a fluid jet in the horizontal and vertical planes. Traditional lancing mechanisms are fixed at an angle and, therefore, much less effective and more time-consuming. The articulating design feature of the DS Articulating Lance allows for complete coverage of the fluid jet into the tank.
The DS Articulating Lance and cold-tap manway procedure can be used to insert a means of injection into the tank without the need to weld additional nozzles onto the tank wall. This eliminates a serious safety hazard that inhibits many tank cleaning projects.
In many cases, chemicals or additives need to be injected into a large above ground storage tank. This must be done without the ability to empty the tank, as to empty the tank to allow for installation of equipment. The DS Articulating Lance provides the ideal solution to safely install a method of injection and an effective means of agitation and mixing. Either from the tank itself, or from alternative sources of cutter stock.
