Surface preparation is the most critical factor to ensure the coating will bond properly to the pipe wall. The in-situ coating process involves two separate methods of cleaning the pipe wall: abrasive blasting and chemical cleaning. Both methods are adequate for obtaining the proper surface preparation and are capable of producing a SSPC-SP 5/NACE No. 1 white metal surface.
The abrasive blasting procedure is typically utilized on newly installed pipelines. Chemical cleaning is utilized for rehabilitating existing pipelines. The coating is designed to effectively adhere to either surface. However, the majority of the I.P.S. work has been credited to chemical cleaning.

I.P.S. is capable of carrying out a multitude of various pipeline cleaning operations. Specialty operations is our specialty. When it comes to tackling those seemingly impossible projects, then look no further than I.P.S. The top notch personnel at I.P.S. has performed countless pig runs and chemical operations, achieving successful results within difficult & unique situations.
Internal Pipeline Solutions is equipped with portable boilers and heat exchangers that can be utilized to improve the effectiveness of any cleaning process. IPS uses Alkaline/Solvent wash for hydrocarbon sludge removal from process piping, and Acid/Chelant treatment for scale build-up inside the pipeline.
IPS’ multi-stage In-Situ preparation and coating process has proven to be extremely effective in completely and uniformly covering the entire length of pipeline with a continuous epoxy barrier.
IPS’ abrasive blasting process is an internal cleaning method that injects hard cleaning particles into a gaseous medium. These cleaning particles impact the internal surface of the pipe wall, removing oxides and hard scale deposits, leaving a minimum NACE 1 finish.
IPS’ utilizes a multi-stage system that consists of both mechanical and chemical cleaning. Prior to coating, IPS will determine that the proper level of cleanliness has been achieved.
“We consider the highly-skilled team that IPS has built over the years to be the very best in the business and we never hesitate to recommend them for projects.”Keith RachelEngineering Manager, Sigma Coatings USA
