Peka-Pro is a series of fusion bonded epoxy products from PEKA CHEMIE that have excellent corrosion and cathodic disbondment resistance along with outstanding mechanical performance on steel pipelines and reinforced steel bars even in severe operating conditions.
The portfolio of Peka-Pro products includes:
Peka-Pro SL (single layer FBE)
Peka-Pro DL (Dual Layer FBE)
Peka-Pro Pr (Primer for three layer and dual layer system)
Peka-Pro Re (Rebar Coating)
Peka-Pro IPC (Internal Pipe Coating for Potable Water)
Peka-Pro SL includes a range of stand-alone fusion bonded epoxy coatings for steel pipelines. This is a cost-effective solution for water pipeline transportation systems. Film property meets CSA Z245.20-10 requirements.
- Excellent corrosion resistance
- High Cathodic disbondment resistance
- Excellent adhesion to metal substrates
- Very good mechanical performance even in high film thickness
- Cost effective solution for customers
Dual layer FBE was introduced to the market in 1999 as an alternative to multi-layer system for directional drilling applications. In the dual layer FBE system two stand-alone FBE are applied one after the other on steel pipelines in order to protect steel pipelines from corrosion, cathodic disbondment and mechanical damage arising from laying, handling, backfilling and horizontal drilling. Dual Layer FBE is much more effective than Single Layer FBE.
Peka-Pro DL as a top coat and Peka-Pro Pr as a primer together show outstanding cathodic disbondment resistance and mechanical performance in severe operating conditions.
Peka-Pro DL from PEKA CHEMIE includes 4 systems according to required application:
- Peka-Pro DL-AR (Dual Layer Abrasion Resistance System)
Pipes are exposed to mechanical stress during handling and transportation. Peka-Pro DL-AR guaranties optimum protection during laying, handling, backfilling and horizontal drilling. Because of its special formulation, Peka-Pro DL-AR enjoys excellent abrasion and gouge resistance to pipelines. Peka-Pro DL-AR meets IGS-M-TP-026 and CSA Z245.20-10 system 2B requirements.
- Peka-Pro DL-AS (Dual Layer Anti-Slip System)
In some projects concrete weight coatings are applied on coated pipes. To prevent slipping, an anti-slip coating as a second layer is applied to pipes. It improves bond strength between pipe and concrete weight coating by increasing friction.
Peka-Pro DL-AS as the external anti-slip coating along with Peka-Pro Pr as a primer ensure excellent cathodic disbondment resistance and anti-slip properties.
The Peka-Pro DL-AS system meets CSA Z245.20-10 system 2C requirement
- Peka-Pro DL-UF (Dual Layer Ultra Flexible System)
During pipe laying some pipes should bend more than usual. Peka-Pro DL-UF as a second layer on Peka-Pro Pr certifies excellent flexibility even in high film thickness. Peka-Pro DL-UF provides flexibility (defined in CSA Z245.20-10 system 2A) beyond expectation.
- Peka-Pro DL-UV (Dual Layer UV resistance System)
In some conditions pipes are not buried and are exposed to sunlight. Since Epoxy coatings will chalk fairly quickly when exposed directly to sunlight, the upper layer of pipe coating must resist UV degradation. Peka-Pro DL-UV applied as a third layer on dual layer system in order to prevent UV degradation of dual layer system under sunlight exposure. Peka-Pro DL-UV is a UV resistant polyester.
Peka-Pro Pr (primer for 3 layers and dual layer system)
Triple-layered polyolefin system is the most famous protective coating for water pipelines all over the world.
The steps to apply include:
- The surface pretreatment of the steel pipeline with shot blast operation
- Application of Peka-Pro Pr on steel surface as a primer
- Application of the copolymer adhesive layer
- Application of polyethylene top layer in strip form with the extruder
This system has excellent cathodic disbondment resistance, high resistance to chemical attack and outstanding mechanical performance. Peka-Pro Pr has wide application range and is also used as a primer for dual layer system. Peka-Pro Pr meets IGS-C-TP-010 and CSA Z245.21 and Aramco 09-SAMSS-089 standards.
Peka-Pro Re (Rebar Coating)
The use of protective coatings has been one of the most efficient methods to protect reinforcing bars, as it creates a physical and chemical barrier between the steel rebar and the corrosive environment.
Among the Fusion Bonded Epoxy products, Peka-Pro Re has been used along with other systems or on its own to protect rebar, dowel bar/dowel bar baskets, welded wire fabric/wire mesh, mechanical splicing, and spirals.
Peka-Pro Re is formulated to help provide superior flexibility for shop or field fabrication that exceeds current AASHTO and ASTM bend requirements. Peka-Pro Re is resistant to corrosive agents such as de-icing salts, airborne salt spray, seawater, harsh chemicals, acid rain, and carbonation, contaminated aggregate and concrete additives.
Peka-Pro Re meets ASTM A 775 / A 775M Standard.
Peka-Pro IPC (Internal Pipe Coating for drinking water)
Peka-Pro IPC has been used for potable water pipelines. For any pipeline internal lining application, the coating must withstand the constant flow of liquid or solid particles. This pure epoxy coating was designed for corrosion protection of water transporting pipelines. Peka Chemie has got approval certificates that conform to TZW.
Peka-Pro IPC also meets the requirements of AWWA standard C213, and BS 6920 listed under WRAS (Cold & Hot water use up to 85 ℃).
