Pulp & Paper: On-Site Metal Spray Cladding

BLRB Waterwall Corrosion ProtectionIGS provides solutions to address operators’ problems within many of the critical boilers and pressure vessels used in the pulp and paper manufacturing process worldwide. We provide corrosion and erosion resistant alloy coatings to protect mission-critical equipment at pulp and paper mills around the globe using proven Metalspray processes. In the USA, our mechanical services group completes general repair and component replacement at your facility and restores process equipment to high levels of reliable performance, in accordance with ASME Section I. Among the most common types of mission-critical equipment serviced in the pulp and paper industry are:



Black Liquor Recovery Boilers & Power Boilers

We have developed our High Velocity Thermal Spray (HVTS) Cladding Systems to protect the waterwall tubes, nose arch tubes and superheater tubes of Black Liquor Recovery Boilers (BLRB’s) from a general loss of wall thickness from the fireside of the furnace.

Batch and Continuous Digesters

IGS coatings mitigate corrosion on the digester shell and on the circ welds where a Heat Affected Zone (HAZ) can be created during the construction process, leaving the circ weld susceptible to Stress Corrosion Cracking (SCC). We couple our technical expertise and our application experience to ensure our customers receive long-term reliable corrosion protection solutions, which increases both the batch and continuous digesters’ reliability.

LTV and Falling Film Evaporators

Our execution teams work dynamically in an outage environment, meeting tight critical path maintenance schedules.

IGS Experience: Field

IGS has over 35 years of experience in the Pulp & Paper Industry. Over the past 35 years, we have provided our Metalspray Cladding Services to many of the leading Pulp & Paper Companies around the globe. Our team of full-time experienced project managers, superintendents, foremen, safety managers, and HVTS technicians ensures that we are always ready to deliver high-quality on-site Metalspray Cladding applications. Being a global company, we do not rely on increasing our pool of technicians with part-time help in the spring and fall and then reducing our pool of technicians in the winter and summer. It is always outage season somewhere, so we can maintain a strong experienced workforce year around.

IGS Experience: Shop

We use a state-of-the-art shop facility in the USA where we can process new replacement waterwall boiler tube panels. We apply also our Metalspray Cladding with automation to new waterwall panels prior to site delivery and installation. This option allows our customers to design long-term corrosion protection solutions, which will enhance the corrosion protection factor of the carbon steel tubes and extend their run time considerably.

IGS Technology

Our core technology is the IGS High-Velocity Thermal Spray (HVTS) metal alloy cladding system, where proprietary highly modified corrosion or erosion-resistant alloys are atomized in a supersonic gas stream, to produce robust long-life protective barriers. We utilize HVTS to provide field-installed protective cladding mitigating corrosion in pulp and paper process environments. Our HVTS cladding systems have demonstrated proven performance in high-temp conditions and provide a protective layer on the fireside of boiler tubes.
