GROSSI S.R.L.

CTRA studies and proposes technical solutions for the transfer of all fluids over long distances, combining chemical compatibility with mechanical and abrasive resistance to ensure a long service life without routine maintenance. The reference project carried out by CTRA in 2006 on behalf of OCP Morocco, which involved the construction of two Ø1800 phosphogypsum discharge lines with a total length of 8km, is a perfect illustration of this. These pipes combine chemical, abrasive and mechanical resistance, and were buried at a depth of more than 12m to ensure a gravity flow rate for a charged fluid. This project required the processing of 3400 tonnes of GRP vinylester over 24 months and was the subject of a case history.

Windstrand® 2000 features a powerful combination of optimized design and reliability for longer, lighter blades. Windstrand® 2000 delivers high weaving efficiencies. The product allows blades to operate in extreme environments at reduced operating costs. We’re happy to offer Windstrand® 2000 in all regions. Packaging (Standard Reference) Rovings are available in a singleend internalpull package. Each pallet weighs approximately 1 ton. Pallets are stretch wrapped for load stability. All doffs are wrapped with TackPak™ for protection and to aid package runout and transfer. Full doffs are approximately 2021 kg (45 lb.) and they can be packaged in bulk or CreelPak™ format. Standard Package Cylindrical bobbin without tube, Outside Diameter (OD) ±270mm, height 260300mm. Partial bobbins have smaller diameter. Max bobbin weight approximately 21kg. 600 Tex and greater. Bobbin covered by a TackPack™ film. Pallet Size 1150x1150mm, 4 ways entry.

PulStrand® 4100 is specifically designed for fast wetout, good processing, high glass loading and excellent laminate properties, to maximize customers’ processing and minimize their processing costs in pultrusion applications. OUTSTANDING MECHANICAL PROPERTIES Excellent shear and flexural properties in major resin systems, provide maximum part strength and long part service life. REDUCED COST Fast, uniform strand wetout leads to higher glass loading, reducing resin demand; fast wetout also increases production speed and productivity resulting in reduced manufacturing cost. MULTIRESIN COMPATIBILITY Excellent glass/resin bonding in polyester, vinyl ester, polyurethane, acrylic, and epoxy resins, providing the processor maximum flexibility with one input glass. This reduces cost with less inventory to carry and eliminates the need for costly downtime and labor to change input glass during job changes. Suitable for LFTP PA compounding applications

PipeStrand® S1000, made for fabricators that want to reduce material cost, while increasing product performance. Designed to provide excellent hydrostatic bases, fight corrosion, increase efficiency and service life in the lowpressure filamentwound pipe, tank and vessel markets OUTSTANDING MECHANICAL PROPERTIES Excellent shear and hydrostatic properties in all major resin systems, provide maximum part strength, long service life and hydrostatic design basis. REDUCE COST Fast, uniform strand wetout in all major resin systems, results in optimized part production speed and increased productivity, reducing manufacturing costs. MULTIRESIN COMPATIBILITY Excellent glass/resin bonding in polyester, vinyl ester, polyurethane, acrylic, and epoxy resins, providing the processor maximum flexibility with one input glass. This reduces inventory and eliminates the need for costly downtime and labor during product change overs.
