Product Description

  • Through structure analysis and investigating problem aspects, we figure out the original causes of problem and provide the perfect solutions to the client.
  • We have more than 25 years experiences in designing and construction of GRP Water Tank, and we can minimize Trial and Errors. We also provide client with perfect repair service.
  • The repair by the outward appearance of leakage only covers temporary repair, not complete repair. Inadequate repair will create more difficult problem and will cost much more money.

  • 1. Products (Section Steel 40 x 75 x 3t Bending Product)
    Section 2nd Moment lx = 34.875cm4    Section Modula Zx = 9.3cm3
    Static Water Pressure Ws = 48 kgf/cm2 Bending Moment Ms = (48 x 1002 ) / 12 = 40,000 kgf * cm
    Bending Stress σ s = 40,000 / 9.3 = 4,301 kgf/cm2 > 1,600kgf/cm2 => NG
    2. Corrective Action (Base Frame Reinforcement after Sealing)
    After Tank Internal Sealing
    As base frame reinforcement is required , we divide 1m portion by three part and support the bottom. We decide this approach minimizes the cost.
    3. Corrective Action Background
    Section 2nd Moment lx = 34.875 cm4 Section Modula Zx = 9.3cm3
    Static Water Pressure Ws = 48 kgf/cm2 Bending Moment Ms = (48 x 33x 100) / 12 = 132,000 kgf * cm
    Bending Stress σ s = 13,200 / 9.3 = 1420 kgf/cm2 < 1,600kgf/cm2 => OK
