I have a few questions regarding fiberglass reinforced plastic pipes
Thread Content
For a recent project, many pipeline industry clients requested the use of fiberglass-reinforced plastic pipes. So I reviewed the relevant specifications and identified several issues; I would appreciate everyone’s advice on them. 1. According to the standards, the minimum nominal diameter for fiberglass-reinforced plastic pipes is also 50; so how should small pipes such as those used for pump return lines, with diameters similar to DN25, be handled? Can small-diameter pipes be manufactured in actual production now? If available, could you please provide a sample 2? According to the standards, the wall thickness of pipes and that of fittings with the same nominal diameter are different – will this have an impact on actual production? 3. Are there any special considerations to keep in mind when designing fiberglass reinforced plastic pipes? I hope everyone will not hesitate to share their insights; thank you
1. It is possible to do this with pipes of small diameter as well; as long as the mold permits it. The smallest pipes we currently manufacture are DN15mm, and the labor required is relatively high； 2. The wall thickness of the fittings differs from that of the pipes, but the inner diameter remains the same, which does not affect the user’s use ； 3. The main things to pay attention to are the selection of materials (resin, reinforcing materials for the lining layer, etc.); it is sufficient to design according to specifications based on different pressures and temperatures. This is a technology that is already well-developed in China.
