The interchangeable appendages come in many different styles depending on the type and hardness of coke or scale that needs to be removed. There is even an interchangeable appendage that will polish the tube wall after cleaning is complete.

Why Choose DDT Inc.?

Our competitors are restricted to using one directional cleaning methods which only traverse from launcher to launcher. This leads to excessive pipe abrasion because of repeated cleaning of less contaminated pipes. In addition, this one directional procedure prevents our competitors from effectively cleaning furnace tubes with changing pipe diameters, leaving deposits behind which accelerate the onset of coking.

DDT’s process utilizes a series of valves to control the direction of Pigg® travel. Since the fouling of heater tubes is not uniform throughout a furnace, DDT operators can precisely direct the Pigg over only the most fouled sections and guarantee the removal of all deposits.

Restore your heater tubing and improve performance, reliability and capacity while maximizing process unit profitability with DDT.
