Calculation of wall thickness for negative-pressure fiberglass reinforced plastic air ducts
Thread Content
What formula is used to calculate the wall thickness of negative-pressure fiberglass reinforced plastic air ducts? Using GB 150 definitely won’t work; it’s only applicable to metals. Is there a specific formula for materials like fiberglass? I would appreciate some guidance from experts, thank you!
Mainly, the parameter standards for non-metallic materials are not provided, making it difficult to carry out calculations
For air ducts, it depends on their diameter; the negative pressure is generally not very high. Making the wall thickness slightly thicker should be sufficient to resolve the issue.
