“SINTEX” FRP MANHOLES
� “Sintex” Fibre Glass Reinforced Plastic Manholes
� Made by Chop Hoop Winding Process
� MOC-Resin-Glass Fibres-Specially Treated Silane sand-Catalyst - MEKP
Sr. No. Particulars FRP Manhole RCC Manhole
1 MOC Fiber Reinforced Plastic Reinforced Cement Concrete
2 Process Chop whoop winding process – Factorymade
Masonry on-site construction
3 Leakage Leak proof as monolithic in construction andno joints
Ordinary concrete manholes installed insections due to weight and these joints arethe source of most leaks.
4 Services Life More then 50 yrs Maximum 10 yrs
5 Maintenance Maintenance free Require routine maintenance
6 Corrosion 100 % corrosion proof Corrode very quickly
7 Standard As per ASTM – D- 3753
8 Weight Far more Lighter then concrete manhole Very heavy then FRP manhole
9 Thickness Smaller wall thickness than concrete means Bigger wall thickness than FRP means9 Thickness Smaller wall thickness than concrete meansdecrease in volume displacement and thusdecrease in buoyant force
Bigger wall thickness than FRP meansincrease in volume displacement and thusincrease in buoyant force
10 Chemical resistance
Fiberglass Composition withstands attack ofhydrogen sulfide corrosion.
Cannot withstands attack of hydrogen sulfideand thus corrode quickly.
11 Time Readily available (Minimum lead time) veryeasy and simple to install 5 manhole per day
time needed to make concrete section jointsto be constructed
12 Manpower & Machinery
No need for heavy equipment. Lessmanpower required to move and install themanhole.
Need for heavy equipment. More manpowerrequired to construct and install the manhole
13 Flexibility Modification/Addition of connections in futurepossible
No Modification /Addition of connections infuture is possible
14 Load Withstand H- 20 axial load. Can withstandfar more weight than a fully loaded cementtruck
Compatibility
� “Sintex FRP Manholes may be used with all types of pipe material including � fiberglass � clay, RCC� steel� PVC� PVC� HDPE etc.
Application Areas
Ø Urban & Rural Sewer lines, Storm water lines and water lines – Through Municipalities
Ø Sewer & Storm water lines in big industrial projects
Ø Townships
Ø Big Projects- Malls, Hotels, Hospitals, Airports etc.
Technicality
Specification:ØDiameter - 4’ (most
commonly used), 5’, 6’ and 8’
ØLength – 3’ to 42’
ØCone top opening
ØThickness
Advantages� Will Not Float:
� Better safety factor against float out than concrete manholes.
� Far smaller wall thickness than ØThickness
Ø 7.5mm up to 3m depth
Ø 9mm up to 5m depth
Ø 12 mm up to 12.8 depth
Ø Traffic load: 20 MT
� Far smaller wall thickness than concrete means a decrease in volume displacement.
� Decrease in buoyant forces on fiberglass manholes.
Production Standards
� “Sintex” FRP Manholes are manufactured as per ASTM D-3753
Installation done in Gomtinagar, Lucknow
