FRP/PP-FRP Duct

Shivas manufacture ducting systems for bulk fume extraction applications. We also supply extraction fans, all supporting steelwork and electrical systems. Ductwork can be supplied in Polypropylene, PVC or GRP coated PVC for extra UV protection in exterior applications. Fume extraction hoods can also be GRP coated for extra impact strength.

Shivas solves corrosion problems in the following fields of applications :

• Chemical : Chlor Alkali
• Chemical : Chlorine dioxide/Sodium Chlorate
• Electro-metallurgical : zinc, magnesium, electroplating
• Pharmaceutical
• Food & drug
• Electronic
• Pulp & Paper

It custom manufactures vessels and piping systems for various applications, from full vacuum service to 150 psig design pressure and from ambient to 350°F design temperatures. Its products are mainly used in Acids, Alkali, Water, Oxidizer, Halogen, Hydrocarbons and Solvent environments.

• Shivas has developed a unique embedding technology specifically adapted to small diameter (1” to 12” Ø) Dual Laminate piping systems.
• Its technology assures consistent bonding properties that meet or exceeds the industry standards throughout the client’s piping system.
• Liner materials are available in PVC, CPVC, PP, PE, PVDF, ECTFE and ETFE.

• The large diameter (above 12” Ø) piping system product line is available with PVC, CPVC, PP, PE and PVDF liner materials. It offers consult services to find out the limit design conditions applicable.
• Pipe fabrication processes such as contact molding and filament winding are used during the FRP portion of the fabrication. Thermoset resins used as part of the laminate are of polyester and vinylester grade. Thermoplastic welding is performed as per DVS 2207, section 3 – Hot gas rod welding standard and DVS 2207.
