These trials are continuing and after 15 months they confirm the intrisically antifouling/antiscaling properties of the coating and the substantially reduced rates of fouling, with the fouling that does occur being limited to dirt and slime that readily dislodges/falls off with the slightest of effort.

At the time the vessel was corroding at around 3,000um per year (of carbon steel), being replaced every 3 years and was then 2 1/2 years into it’s life – it had around 6 months of corrosion allowance remaining before it would be condemned.

In July 2011 (after over 3 1/2  years) the vessel continues to be in use with the EN plating effectively halting the underlying carbon steel corrosion. That’s more than an extra 3  years life on top of the 6 months anticipated.

Applied coatings can be high heat/high corrosion resistant, antiscaling  and/or low friction.

The trials are confirming the intrisically antifouling/antiscaling properties of the coating and the substantially reduced rates of fouling with the fouling that does occur being limited to dirt and slime that readily dislodges/falls off with the slightest of effort.

Measure width of stairs and select the appropriate size nosing from the standard range or order custom sized nosings if required. Safety Stair Nosings can be attached to various substrates in a variety of ways.

Fixing to Steel

Stair Nosings are pre-drilled to simplify fixing to steel grid or mesh stairs and platforms. Simply attach using the optional brackets ensuring that nyloc nuts are fully tightened.

Fixing to Concrete

To fix to concrete stairs place the nosing in the correct position and mark the position of the holes with a marking pen or a 6mm masonry bit. Remove the nosing and drill marked holes to the correct size and depth to suit
wall plugs. Hammer in wall plugs, place nosing back in position and secure with domed head screws.

If a sealed edge is required for reasons of hygiene then apply a bead of sealant to the edge of the nosing prior to fixing into place. Ensure the floor area under the nosing and the nosing underside are clean, dry, free from oil, grease, loose or flaking paint and any contaminant likely to interfere with adhesion of the sealant. Oil, grease and other contaminants should be removed using a suitable solvent or an industrial detergent. Loose or flaking paint should be removed with a scraper or sander to provide a sound substrate.

Fixing to Timber

Safety Stair Nosings can be fixed to a timber substrate by using a suitable self-drilling screw.

Adhesive

Safety Stair Nosings can fixed to many substrates by the use of adhesive alone providing a high performance adhesive is used. Sikaflex 11FC or equivalent is recommended. Ensure the floor area under the nosing and the nosing underside are clean, dry, free from oil, grease, loose or flaking paint and any contaminant likely to interfere with adhesion. Oil, grease and other contaminants should be removed using a suitable solvent or an industrial detergent. Loose or flaking paint should be removed with a scraper or sander to provide a sound substrate. Thoroughly abrade the underside of the nosing to provide a suitable “mechanical key” for adhesive and then apply the adhesive to underside of nosing and press firmly into place. Take steps to ensure nosing is not inadvertently moved or disturbed during the curing process.

Ladder Rung Covers

Measure the existing ladder rungs and select the appropriate size Ladder Rung Cover. Ensure ladder rungs are clean, dry, free from oil, grease, loose or flaking paint and any contaminant likely to interfere with adhesion. Oil, grease and other contaminants should be removed using a suitable solvent or an industrial detergent. Loose or flaking paint should be removed with a scraper or sander to provide a sound substrate.Apply a generous amount of polyurethane based adhesive (i.e. Sikaflex 11FC) to the Ladder Rung Cover and press firmly into place. Clean off any excess adhesive. Use adhesive tape to hold the cover in place until the adhesive is fully cured.

SRC High Pressure Pipeline Repair System is a system developed to repair high pressure gas pipelines on the run. The system is designed for the repair of localised areas of corrosion and the resultant reduced wall thickness, it reinstates the pipeline to its original pressure rating and is completed whilst the gas is flowing.

Once installed the corroded section of pipeline is encased in a fully welded sleeve, this sleeve is filled with an incompressible epoxy filler. The final repair has greater burst pressure to that of the original (uncorroded) pipe.

The photos above show a hydrostatically tested repaired pipeline of a around 5mm thick wall thickness with 2 simulated areas of corrosion, these areas were ground down to around 1mm wall thickness, the SRC repair was completed over the “corroded areas” and the pipeline tested. The pipeline burst beyond the repaired area and an added benefit is that the repair also stopped crack propagation. The repaired pipeline was sectioned and showed the two “corroded” areas, non-compressible epoxy filler and much stronger outer sleeve.

This system comprises of SRC Pipeline repair sleeves, SRC Pipeline Repair Putty and SRC Pipeline Injection Epoxy.

The area requiring repair is abrasive blast cleaned, inspected and the repair sleeves are clamped to the repair area, the sleeves do not make electrical contact with the pipeline, the two sleeves are then fully welded together and the ends sealed with SRC Pipeline Repair Putty. SRC Pipeline Injection Epoxy is then injected into the pipeline/sleeve void and forms a non-compressible grout that transfers burst forces from the inner pipeline to the outer sleeve.

• High Pressure Gas Pipeline repairs on the run without disrupting the gas flow.
• Better than new pressure rating.
• Can be fully installed in a normal shift.
• Could be modified and tailored to suit a variety of Oil & Gas pipelines and Risers
