Continuous Filament Winding Technology

Technobell is the world’s leading provider of CFW technology for GRP pipes production.

The Continuous Filament Winding (CFW) technology is the ideal solution when Glass Reinforced Polyester (GRP) pipes are used for water transmission and distribution, desalination plants, cooling systems in power plants, irrigation projects, sewage etc.

CFW Technology Advantages

The CFW technology is intended for high production volumes. GRP pipes manufactured with CFW technology are used in most civil applications, whether gravity, pressure below ground or above ground.

The CFW process has the following advantages:

  • High production capacity.
  • Low raw materials consumption.
  • Low fixed cost per end product.
  • Low total production cost per end product.
  • Wide range of diameters.

The Technobell CFW technology is distinguished by the following advantages:

  • High production capacity
    Very high pipe production speeds reaching 60 m/h, resulting in considerable reduction of pipe production cost and delivery times.
  • Proven technology
    Advanced know-how and optimized pipe design confirmed by long term testing according to international standards enable our clients to be competitive on the market.
  • Built-in experience
    The Technobell CFW technology is a result of years of experience in pipe production and pipelines installation. This experience is available to our clients also as a service provided by our specialists.
  • Automated and reliable production process
    Computer controlled CFW machine guarantees stable and high production quality and minimizes the human error factor.
  • Diameter range from 300 up to 4000 mm
    A wide range of diameters and a unique system for diameter change resulting in 40% operation time reduction for all diameters.
  • Minimized waste during production
    Improved raw materials distribution system guarantees high pipe quality and low waste.
  • Low production cost
    An important advantage, perhaps the most important from the investor’s point of view is a combination of all other advantages and is the end goal of our technology. Making the process reliable will result in less production failures, increasing the production capacity will decrease the manufacturing time, minimizing the waste will reduce the use of raw materials and having a wide production range will decrease the investment size. All this advantages put together will result as the ultimate advantage, i.e. production cost reduction on one side and profit increase on the other side.

CFW process description

Process description

The main principle of continuous advancing mandrel process is to use glass fiber reinforcements in the circumferential direction of pipe. Hoop rovings provide strength to GRP pipe against circumferential and external loads. Chop rovings inside of pipe structure empower the strength against longitudinal loads and multi direction loads. Silica sand is used in the pipe core and enables the pipe to have a sandwich structure. In some special cases, vinylester and other resins can be used instead of polyester resins.

High level of automation

The CFW Machine is completely digitally controlled by an advanced PLC controller. All machine operations and the dosing system are controlled by computer. Remote connection can also be used for off-site support and troubleshooting thus allowing the client to save time and run the production smoothly 24/7.

Production line

All continuous filament winding pipe production operations are performed on the CFW Machine. The GRP pipe is produced continuously, cut at the required length, the spigot diameter is calibrated on-line and the pipe is immediately ready for testing and installation.

Technobell also designs and supplies various CFW Auxiliary Machines (Pipe Hydro-Testing Machine, Sleeve Grooving Machine, Off-line Rectification Machine, Sleeve Hydro-Testing Machine, Sleeve Joining Machine and Pipe Transport Trolley) and the Universal Testing Machine.

LAB EQUIPMENT (Universal Testing Machine)

The Universal Testing Machine (UTM) is used to test the tensile stress and compressive strength of materials. It can perform many standard tensile and compression tests on materials, components, and structures such as:

  • axial tensile according to ASTM D 638,
  • hoop tensile for DN >250 mm up to 2000 mm – split disc method according to ASTM 2290,
  • hoop tensile for DN > 2000 mm up to 4000 mm – short strip method according to ISO 8521 method D,
  • flexural strength according to ASTM D 790,
  • compression according to ASTM D 695 and
  • pipe stiffness according to ASTM D 2412.

GRP FITTINGS

Another advantage of the GRP pipe system offered by Technobell are customised fittings.

Technobell know-how and equipment enables the manufacturing of a full range of GRP fittings such as:

  • elbows,
  • tees,
  • reducers (concentric, eccentric),
  • flanges (fix, loose, blind),
  • wyes,
  • sleeve joints and
  • others.

GRP pipe fittings cover many components that connect pipe ends for in-line, offset, multi-port, and mounting configurations.

Fitting cross sections are circular in shape to mate with the pipe sections they are connecting. They are used in pressurized applications and non-pressure applications such as drainage, waste, and vent systems.

TYPICAL GRP JOINT TYPES

GRP pipes are joined with:

  • GRP Sleeve,
  • GRP Flanges,
  • GRP Lamination – welding and
  • others.
