Manhole Sealing Plate

Brief Description of the Process:                                                                                              The manufacturing process is called “Resin-Transfer-Moulding” (RTM). The composite materials of        resin and reinforcements are molded on a two-piece mould which will result in “both-side-smooth”            surface finished product.

Dimensions:

Inner diameter (ave.) 562.7 mm
Outer diameter (ave.) 575.3 mm
Wall Thickness (ave.) 5.4 mm
Glass-to-resin ratio 35:65
Barcol Hardness 50
Barcol Hardness A direct load of 150 kgs. loaded at the
center. Deflected 25mm at the center.

Short Term Chemical Resistance Test:

Test medium 10% H2SO4
Immersion Period March 10, 2004 to July 15, 2004
