How to Combat Corrosion with Pipe Wraps
Pipe wraps like Belzona SuperWrap II excel at repairing and reinforcing pressurised pipes. For pre-qualifying their system, manufacturers complete internationally recognised test standards such as ASTM G48 for corrosion resistance and ASTM D4541 for adhesion strength. Consequently, engineered composite pipe wraps provide a robust solution for corrosion protection, structural reinforcement, and leak sealing, effectively extending the lifespan of industrial piping systems.
Material Selection in the Petroleum and Natural Gas Industries
In industries such as petroleum, petrochemical, and natural gas, manufacturers choose materials to fabricate flowlines, pipelines, and platform components based on their strength, corrosion resistance, and environmental suitability.
Subsequently, common choices include carbon steel for its cost-effectiveness and strength, stainless and duplex stainless steels, and corrosion-resistant alloys for superior corrosion resistance, along with alloy steel for high-temperature situations. Furthermore, manufacturers select each material according to the specific requirements for resistance to pressure, temperature, and corrosive conditions.
Even when using strong and durable materials, corrosion remains a prevalent issue in these critical sectors, therefore, addressing these issues is paramount for maintaining operational integrity.
Stainless steel – corrosion resistance 
Carbon steel – cost effective 
Alloy steel – high temperatures
Repair Options for Pressure Equipment
You can apply Belzona composite wrap systems in situ, with no need for a shutdown. This method ensures safe operations while minimising downtime, and it provides cost savings and environmental benefits.
The Belzona SuperWrap II pipe wrap meets industry standards ISO 24817 and ASME PCC-2, making it a reliable choice for various applications.
You might also consider alternative solutions such as welding, mechanical clamps and reinforcement sleeves, epoxy coatings, or replacing damaged sections, depending on specific repair needs. For effective and durable industrial pipeline wrapping, Belzona SuperWrap II offers an optimum solution.
Step-by-Step Guide: How to Repair Pressure Equipment with Engineered Composite Pipe Wraps
This guide provides step-by-step instructions on pipeline wrapping, specifically to repair pressure equipment and piping with ASME PCC-2 compliant engineered composite repair systems.
STEP 1: Pre-surface preparation
Use masking tape to mark the repair area, including at least 7.6 cm (3 in) on either side, covering the defect, the total overlay, and the taper length.
Step 2: Surface preparation
Begin by cleaning the pipe to remove any dirt, grease, or debris. Use a wire brush or sandblasting to achieve a rough surface profile, which helps the wrap adhere better.
Grit blast the repair area to achieve cleanliness levels in accordance with SSPC-SP- 10/ NACE 2/ Sa 2 ½ (Near White Metal) and an average minimum angular profile of 75 µm (3 mil). Use the Testex tape method to measure the substrate profile.
Apply a degreasing agent to the pipe surface to eliminate any remaining oils or contaminants.
Step 3: Measuring and cutting
Accurately measure the length and circumference of the pipe section to be wrapped, including bends, straights, and tees.
Cut the composite wrap to the required dimensions. Ensure you have enough material to overlap by at least 50% for each layer.
Step 4: Mixing the resin
Mix the Belzona SuperWrap II resin according to the manufacturer’s Information for Use sheet.
Step 5: Wetting out
Apply Belzona SuperWrap II resin to the repair substrate. Make sure that all the repair area is wetted out. As the resin is fluid, it will spread quite easily and can be brushed in.
Using an applicator, brush, roller, or rubber squeegee, saturate the hybrid reinforcement sheet (carbon fibre/glass fibre) with resin.
Step 6: Application
Starting from either end of the repair area, apply the composite wrap sheet onto the substrate applying tension. There should be resin exuding through the fibers.
Continue the pipe wrap with at least 50% overlap until the other end of the repair area is reached.
Step 7: Release film
To consolidate the pipe wrap with two wraps of Belzona 9382 release film with a minimum 75% overlap.
Step 8: Curing
Allow the pipe wrap to cure according to the manufacturer’s Information for Use sheet. This typically involves letting the resin cure for a specific period under ambient conditions. Once cured, remove the Belzona 9382 release film.
Ensuring an ASME PCC-2 or ISO 24817 Approved Pipe Wrap
Wrapping pressure equipment and piping with engineered composite repair systems like Belzona SuperWrap II offers a durable and reliable method for repairing and reinforcing pipes.
These step-by-step instructions aim to show you how to achieve a secure and long-lasting pipe wrap that adheres to industry standards.
To ensure your repair meets ISO 24817 and ASME PCC-2 standards, a trained and validated Belzona SuperWrap II designer must design the composite repair solution. Only Belzona-trained and certified Belzona SuperWrap II Installers and Supervisors should carry out the application of the pipeline wrapping.
