Compared to polyester, vinyl ester resin has very good chemical resistance, especially against acids. High temperature and chemical resistant vinyl ester-based resins, e.g. Novolac vinyl ester, are also available. The Vinyl Ester resin will hold up to 90 deg Celsius. Compared to polyester, vinyl ester resin has very good chemical resistance, especially against acids. High temperature and chemical resistant vinyl ester-based resins.
Composite Pipes Industry with its Engineering department capability and experience can provide customize Engineering solution to the customer starting at the early stage of the project. CPI has a big advantage of having in-house design capability along with the manufacturing unit of the GRP piping System. Production difficulties encountered along with effective quality system provides the necessary input to design to take into account and make necessary changes to the GRP product design to provide an economical and reliable product which meet the customer requirement up to the highest level of customer satisfaction. Moreover, Having the design facility as an own design consultation along with the field service workforce which monitors the complete process include from offloading of material, bonding, installation, and commissioning of GRP piping system. We provide the feedback needed to improve the design and incorporate the difficulties face by the customer so as continuous improvement in design. Modulus of Elasticity of FRP product will be 10‐20 times less than the traditional metallic pipe. This is typical for all FRP products manufactured with E‐glass. This is because of the strength of E‐glass. The material selection process shall ensure that the material is compatible with the service fluids to which it is exposed over the full design temperature range so that the mechanical, physical, and chemical properties of the GRP satisfy the design requirements throughout the intended lifetime. CPI shall provide the details of the raw materials and resin systems intended to be used for the project during the technical bid stage for the company Review and acceptance. Fiberglass pipe is a composite material system produced from glass fiber reinforcements, thermosetting plastic resins, and additives.
The service for the Vinyl Ester resin is :
Minimum thickness:2.5-4 mm Layer build –up from inner pipe surface to outer surface: · Double Veil Layer (VL) made of either C-glass or ECR glass. · Chopped Strand Mat(CSM) made from ECR glass with a total mass per unit area greater than or equal to 900 g/m2 The fiber content of CRL shall be between 25% and 35% by mass
Minimum thickness:2.5-4 mm Layer build –up from inner pipe surface. · Double Synthetic Veil Layer(VL) followed by · A chopped strand mat(CSM) made up of E-glass or E-CR glass with a total mass per unit area greater than or equal to900 g/m2 The fiber content of the CRL shall be between 25% and 35% by mass
Thermo- Plastic lining (TPL) UnPlasticized PVC liner with a thickness of 3 to 4.5 mm
GRVE pipe can withstand up to 20-30 bar design pressure depends upon meeting the qualification requirement as per IS 14692-2 and DEP 188.8.131.52.
