Added strength cuts pipe width

MATERIALS - Cutting Edge

FIBRE and composites manufacturer Owens Corning has introduced a reinforcement designed to help stop high-pressure pipelines fracturing in extreme environments.

The firm claims its SE 2350 reinforcement could help increase the burst strength of oil and gas pipes by 17 per cent.

The company said that a roving reinforcement bound around an epoxy pipe during manufacture could also increase stress resistance and slash costs by improving production efficiency.

During development the research team looked at the critical factors in the production process and incorporated design features that provide less frictional resistance, resulting in lower defects and less scrap.

The improved burst strength also allows manufacturers to reduce pipe thickness by 10 per cent.

Owens Corning product manager Wisdom Dzotsi claimed that the reinforced composite pipe sector was ripe for massive expansion and that the SE 2350 reinforcement would help manufacturers take advantage.

He said: 'With high steel costs and high gas and oil prices driving increased sector activity, we are poised for a growth rate of composites in piping applications of more than twice that of general industry.

'With SE 2350 our customers can take full advantage of that growth with less scrap, increased production speed and volume and lower maintenance and rework costs.'
