GCER - Industrial Tubes
GCER has a very comfortable production capacity of industrial tubes and a large range of pipes and fittings for industrial environments with different types of resins: polyester, vinylester and orthophthalic that meet the various demands of customers according to projects.
GCER is able to produce industrial tubes SVR / GRP for ground or air use by continuous filament winding process. Industrial Pipe SVR / GRP of GCER extends from DN 80 up to DN 1800 with a specific command for larger diameters
The association between fiber and matrix can simultaneously enjoy the benefits of each of the two phases: high strength and high modulus for fiber, low density and good chemical resistance resins.
This combination allows the use of SVR / GRP in extreme conditions and provide solutions for the transport of aggressive media, corrosive in presence of high temperature and / or pressure.
These pipes can be used for:
- Drinking water supply
- Industrial and domestic Wastewater Treatment
- Cooling Networks
- Sea Emissary
- Seawater desalination unit
- Cooling system, heating and disposal of effluents.
- Chemical industry.
The development of composite materials around us is spectacular. All experts predict them an even brighter future: we even proposed to call this period, the age of composites. The features and advantages of SVR – GRP pipes, make them the recommended product in terms of cost and durability.

A SVR – GRP GCER TUBE SVR - GRP GCER CONSISTS OF THREE PARTS:
I + II: Anticorrosion Layer
I = Sail
II = Mat
III: Mechanical resistance layer
III = roving yarn
IV = sail trim
e2= strength layer
- An anti-corrosive or chemical barrier: a resin-rich layer. The thickness of the layer and the type of resin depends on the nature of the fluid in the tube and the operating conditions.
- A layer of strength: manufactured by continuous filament winding, made of vinyl or polyester coated glass fiber resin, and deposited on a rotating mandrel by a machine. This machine consists of a rotating mandrel, a distributor arm - which moves along the rotating mandrel depositing the materials on a well-defined angle, a storage area for the glass fiber and a hot resin.
The mandrel may be replaced by a tube made of the required material and thus, it will constitute the tube liner.
This manufacturing technique allows the use of glass fiber reinforcement in the circumferential direction. During the use of these buried pipes or high pressure applications, the majority of the load is concentrated in the circumferential direction of the tube; this is why the incorporation of continuous glass fiber reinforcement in this direction provides a product with a better yield.
The winding angle is a fundamental parameter for all VSP / GRP pipes made by filament winding. This angle directly regulates the ratio between the circumferential and the axial characteristics of the designed pipe and it is the ratio of the circumferential pressure (hoop tension) and the axial pressure (axial tensile strength). A pipe designed with a winding angle exceeding 65 ° is a pipe with optimal circumferential properties but low axial performance. For underground installations, a winding angle close to 65 ° is proposed to provide superior resistance against the load on the ground, vertical loads and internal pressure. On the other hand, for aerial installations, the winding angle will be close to 55º, since the tube must be provided with superior characteristics in the axial direction.
Silica can also be used, as it increases the stiffness of the tubes.

GCER pipes and fittings are subject to strict controls in order to verify compliance concerning standards.
GCER offers a wide range of pipes and fittings that meet the expectations and demands of all applications and industries.
GCER offers a wide range of tubes varies diameters, pressure and stiffness.
The bar pressure range is as follows:
1 (gravity). 6. 10. 16. 20. 25. 32
The range of standard diameters in mm is:
80. 100 • 150 • 200 • 250 • 300 • 350 • 400 • 450 • 500 • 600 • 700 • 800 • 900 • 1000 1100 • 1200 • 1400 • 1600 • 1800
The tubes of standard lengths are 6 and 12 ml :
For the entering pipes, GCER offers a range of tubes with the following specific rigidities:
Other stiffness classes are available on request.
Spigot Bell Assembly :
It is the most used assembly due to the benefits it offers:
The BELL part is obtained during the manufacturing of the tube
The Spigot portion is obtained by machining.
Sealing is provided by elastomeric O-rings installed in grooves machined on the Spigot party.
The insertion of a locking key through the groove of the Bell part shares the axial forces along the tube that can withstand to longitudinal forces.
Assembly by Hooping:
This type of assembly is a permanent link using reinforcements of glass and resin fibers for lamination. The thickness and width of the laminate depend on the diameter and pressure.
Flange assembly (removable junction):
This method is used to connect the tubes to other system components, for example a valve.
