The Yongchang-brand glass fiber reinforced plastic (FRP) pipe produced by our company can be designed and manufactured in various sizes and configurations according to customer requirements. We can produce pipes of any specification and pressure, and can also be made into composite pipes such as PVC/FRP, PP/FRP, PVDF/FRP, etc. according to the conditions of use. Our designers can calculate the hoop stress, axial stress and bending Poisson's ratio coefficient of the product according to your available space, chemical fluid requirements and applicable natural conditions, so as to give product selection, product thickness and layering. Detailed manufacturing process parameters. All the pipes we design comply with industry standards, such as ASTM d2996 filament wound "glass fiber" (glass fiber reinforced thermosetting resin) pipe standard specification filament wound pipe
1. What is the difference between FRP and GRP
GRP and FRP pipes (referred to as GRP and FRP) are interchangeable in the fiberglass pipe industry. FRP is the abbreviation of fiber reinforced plastic, which is a term commonly used in the United States. GRP is a noun with the same meaning. But it is widely used in Europe and Asia and represents glass fiber reinforced plastic.
2. Advantages of FRP
(1) Good corrosion resistance
Most FRP pipes with resins, glass fiber reinforced materials, and composite structures are considered suitable for chemical applications and provide consistent corrosion resistance. There are still some extreme chemical services, special structures and alternative resins should be considered.
(2) Various applications can be customized
In standard fiberglass pipes, customized pipes, special manifold systems, pipes or chimneys, Yongchang provides long-term corrosion solutions and the absolute maximum product life.
(3) Lightweight (20% of steel, 10% of concrete)
(4) Excellent self-weight strength (stronger than steel on the basis of equal weight)
The excellent toughness of glass steel pipe makes it resistant to resin cracking and cracking when subjected to large design loads. In addition to high fatigue resistance, this toughness also provides a safety factor for impact damage during transportation and installation.
(5) Low friction coefficient (more than 25% higher than steel)
(6) Excellent dimensional stability
(7) Low thermal conductivity (saving insulation costs)
Resist the influence of sunlight and other weathering elements. If the fiberglass tube is external, it can be polished and resin coated or painted after years of weathering under particularly harsh conditions.
(8) Long-term maintenance costs are low
