Careful preparation of substrates is important. Correct preparation ensures that the durability of the fire protection system is maintained and the required level of adhesion is achieved. Poorly prepared substrates may compromise the long term corrosion protection to the structure. Where mechanical fixings are attached to the substrate, careful attention is required in order to reinstate the corrosion system after the fixings have been attached. It is required that the substrates are prepared in accordance with Isolatek’s written instructions.
CAFCO® FENDOLITE® M-II / ISOLATEK® TYPE M-II does not cause corrosion to steel. However, for petrochemical environments, the steelwork must be suitably primed, painted or galvanized prior to the application of the CAFCO FENDOLITE M-II / ISOLATEK TYPE M-II System. All primer/paint systems must be fully cured in accordance with the manufacturers’ application instructions.
The substrate to be protected with the CAFCO FENDOLITE M-II / ISOLATEK Type M-II system must be prepared such that it is free from dirt, dust, oil or other contamination that would impair the adhesion of the CAFCO FENDOLITE M-II / ISOLATEK Type M-II system. Pre-existing protective primers and coatings must be sealed prior to the installation of the CAFCO FENDOLITE M-II / ISOLATEK Type M-II system with ISOLATEK® SBK-113 sealer / keycoat. As an alternate, a galvanized diamond lath may be installed as a substrate for the system.
The reinforcement system for steel structures is galvanized or plastic coated galvanized woven wire or hexagonal mesh. The mesh is secured to the steel by use of stud welded, helical or powder actuated fasteners. The reinforcing mesh is held to the substrate at the fixing points, and then pulled away from the substrate to the middle third of the total thickness of the CAFCO FENDOLITE M-II / ISOLATEK TYPE M-II or CAFCO FENDOLITE TG / ISOLATEK TYPE TG product as it is being applied.
For certain applications, galvanized diamond lath may be used. The lath is secured to the substrate in either a contour or boxed configuration in accordance with Isolatek’s application Instructions and design guidelines.
For storage vessels and spheres, the mesh retention system is installed such that no mechanical fixings are required to be attached to the substrate. The method of installation depends on the type and size of the vessel to be protected.
The CAFCO FENDOLITE M-II or TG / ISOLATEK TYPE M-II or TG is then applied to the surface of the mechanical reinforced substrate in accordance with our written application instructions. Refer to our Application Techniques section for more details regarding the step by step processes used.
CAFCO® FENDOLITE® M-II & TG / ISOLATEK® Type M-II & TG
Maintenance and Repair Procedures of the CAFCO FENDOLITE M-II / ISOLATEK Type M-II and CAFCO FENDOLITE TG / ISOLATEK Type TG System for Petrochemical Facilities – Short Form.
Routine maintenance performed through testing and inspection of Spray-Applied Fire Resistive Materials (SFRMs) ensures that the product will be in-place for its intended life cycle.
Petrochemical structures are continually exposed to severe environments. As a result, the fireproofing system is susceptible to damage caused by items such as impact and weathering.
A Maintenance program is essential to maintain the integrity of a completely installed fireproofing system. The complete system consists of the steel substrate (i.e. galvanized or primed/coated), metal lath or mesh, anchoring system (i.e. shots, pins, studs and/or wire ties), the fireproofing material, along with the sealer/top coat (if required) and caulking system.
A complete survey of the fireproofing is needed in order to maintain the system and project future cost of the Maintenance Program.
The survey must be conducted by a N.A.C.E. Inspector with knowledge of the fireproofing system, and recommended and approved by Isolatek International.
The procedures outlined below are intended as a guide for conducting your maintenance program. The N.A.C.E. inspector will need a complete copy of the drawings (steel, equipment and support) for mark up, along with access to the project site. The drawings are to remain with owner and/or owner’s rep upon completion of survey.
The N.A.C.E. Inspector will divide the survey in segments (i.e. pipe rack, equipment, HCU unit, Alkyd unit, Diesel unit, etc.) so that all areas and units have their own cost / breakdown for tracking purposes.
1.0 INSPECTION
1.1 The N.A.C.E. Inspector will inspect and record on the drawings all areas of concern including but not limited to locations where:
- Fireproofing system is damaged
- Corner bead is damaged (if used)
- Previous repaired areas
- Delamination areas
- Cracking
- Mildew
- Chemical stain/damage areas
- Wet areas
- Top coat/sealer failure
- No caulk or improperly applied caulk
- Areas that may have steam discharge onto the system
1.2 The N.A.C.E. Inspector shall submit to the owner and/or owners representative all of the drawings with the mark ups, along with a written procedure to complete all of the necessary repairs of the fireproofing system in accordance with Isolatek International’s guidelines.
2.0 Decision
