About DDT
Decoking Descaling Technology Inc (DDT) was founded in 1991 by Orlande Sivacoe, the inventor of off-line bi-directional hydraulic pigging of fired heaters for Delayed Cokers in Oil Refineries and Bitumen Upgraders. Orlande has led the growth of the company to a Global Leadership position with clients in 51 countries and over 150 refineries.



Technology Platform
Decoking Descaling Technology Inc (DDT) has developed the most advanced system for off-line decoking of fired heaters. DDT's technology can remove the hardest coke and scale that forms in commercial fired heaters or pipelines using a set of our cleaning tools we call DDT PIGGS.

DDT Pigg decoking

DDT Decoking Process is Bidirectional, allowing the cleaning tool PIGG to navigate the furnace tubes in both directions.

A series of valves control the direction of the Pigg travel. Since the fouling of heater tubes is not uniform throughout a furnace, DDT Operators have the ability to direct the Pigg over only the most fouled sections.

This bidirectional cleaning control also permits the decoking of furnace tubes with variable pipe diameters, and prevents the unnecessary repeated cleaning of less contaminated pipe sections, therefore reducing pipe abrasion.

The Pigg Designs and Mobile Dual ( 2 pumps on trailer) and Quad Pumper (4 pumps+ patented Technology) on one Trailer are Best-in-Class. DDT keeps Fired Heaters clean as they are operating, no shutdown to clean. DDT's operators and project managers are the best in the business with deep industry experience accumulated over the past 21 years.
