Traditional decoking methods like steam-air/thermal decoking and chemical cleaning can cause mechanical damage due to over-cleaning and often fail to remove internal debris effectively. Mechanical decoking pigging offers a superior solution—more efficient, precise, and environmentally friendly compared to thermal decoking and hydro blasting.
At Mun Siong, our expert team uses the right tools and techniques to ensure thorough cleaning without tube damage. With over 25 years of experience, we specialize in cleaning heater and boiler tubes ranging from 2” to 12” diameters,
Mostly consists of light coke accumulation and
does not require high temperature application.
Tube diameters are typically 6″ to 8″.
Mostly consists of light coke accumulation and
does not require high temperature application.
Tube diameters are typically 3″ to 12″.
Mostly consists of heavier coke accumulation and
requires a high temperature application. Tube
diameters are typically 3″ to 5″.
Mostly consists of heavier coke accumulation and
requires a high temperature application. Tube
diameters are typically 4″.
We have specially designed decoking pigs that are fully compressible. They are able to go through 90 and 180 bends without a struggle. While durable, they are breakable under pressure. This is to ensure that no harm done to the inner walls of your pipes when the decoking pig experiences any difficulty passing through the pipe.
We connect you with a variety of reliable partners in the industry that provide top-grade services. IP services give our customers the assurance that the decoking services that we carry out is with the outmost care and precision, with no damage to the inner walls of your pipes.
One unique service that Pegasus offers is the cleaning of common headers. We use a HDS to eliminate the need of cutting and rewelding your pipes as it damages and causes unnecessary trauma to the pipes. The HDS enables convenient inspection of tubes with shared headers, eliminating the need for heavy machinery and allowing for precise and efficient evaluations.
Complete Cleaning: Compared to manual or less advanced procedures, the system’s design guarantees full covering of the equipment’s surface, resulting in a more thorough removal of coke.
Efficiency and Speed: Cleaning time is greatly decreased by automated cleaning fluid distribution, which also minimises downtime and boosts overall process efficiency.
A custom-built Double Pumping Unit 40ft container, often called a DPU, is a containerised unit and is specifically designed to connect and deploy mechanical “scraper” pigs.
These are the main components to the unit:
We, Pegasus Advance Engineering a subsidiary of Mun Siong Group of Companies (since 1969), have over 26 brilliant years of experience in this widely prefers technique – De-coking.
Mun Siong is partnered with major ILI companies, providing In Line Inspection using Optical In Line Inspection tool and UT In Line Inspection tool. With 4k resolution, Optical pigging helps in detecting corrosion, coke deposits, pitting and cracks. UT In Line Inspections with high resolution data is interpreted for measuring wall thickness with ID/OD discrimination, geometric assessment, coke deposit, corrosion, etc.
We have the most effective and advanced technology with full 360 degree coverage for complete cleaning. We have invested in specialised pigs that navigate 1D bends, plug headers, and flat back bends. With our track records, we ensure zero damage to process tubes and minimise downtime for faster operations.
