Conventional tanks (concrete or mild steel) are prone to aging, wear and corrosion.
Concrete can crack when exposed to erosion and natural disasters, leading to water
contamination and leakage â?? and usually canâ??t be repaired. MS rusts easily and its also
easy heat conductor.
FRP â?? Fiber Reinforced Polymer is a strong but light weight glass fiber reinforced plastic
composite used in the aerospace, automotive, marine and construction industries. It has
a high-strength to weight ratio, an extremely long lifespan, and easy to maintain as well as
heat resistant.
FRP sectional panel tanks provides all types of advantages which other liquid storage
methods doesnâ??t. These tanks are DURABLE, LEAK-FREE, COST-EFFECTIVE OVER LIFECYCLE as well as EASY TO INSTALL, RECONFIGURE AND RELOCATE. This is an ideal option
for a wide range of usage including potable water storage, food and factory production,
commercial mining, fire protection, industrial liquids, rainwater harvesting, seawater
storage, and any other kind of liquid and granular storages.
Pipes & ducts are manufactured using the "dual helix" filament winding process on computer controlled machines. By adjusting the relative speed of mandrel rotation and glass distribution head movement, helical reinforced layers with different angles can be wound. In order to increase the pipe stiffness, especially on large diameter pipes, silica sand can be added to parallel layers of wall.
Nominal diameter
Nominal size of pipe and fitting is based on internal diameter. The range of available sizes is 25 to 3000 mm.
Nominal pressure classes:
Pipes and fittings are classified according to nominal pressure. Standard pressure classes are 4, 6, 10, 16, 20 and 25 bars. Intermediate or higher-pressure classes are considered on request or depending on the design parameters and conditions
Nominal lengths
Pipes have a length of six meters up to nd150 and 12 meters for bigger diameters.
Fittings
A wide range of fittings as elbows, reducers, tees, caps, flanges etc. Is available.
Fittings are manufactured by the hand lay-up, contact molding and spray-up process. In hand lay-up and contact molding processes veil and alternate layers of mat and woven roving saturated with resin are applied on the mold. In spray-up process continuous strand roving is fed through a chopper gun, combined with catalyzed resin, and sprayed onto the mould surface
Prefabrication spools
Prefabricated spools save installation time as well as costs, freeing the designer from being limited to standard fittings and allowing junction sizes shapes to be specified and manufactured as a better alternative to a complex series of joints.
The water tank is is widly used in public water supply system in industry, buildings and so on. SMC GRP Water Tank is popular with all around the world now. It has lots of good performance like stretch-proof, bend resistance and anti-aging. Sealed through special glue, and no toxic, water resistance and small transfiguration.
Compared with Iron & steel Tanks
Lighter (Only1/4 of Iron and Steel¡¡¥s density)
Mechanical Properties is better
Better Performance on Resistance of corrosion
Inside surface is easy to clean
Easy to be maintained
According to the shape of media, FRP vessels can be divided into three categories of liquid, gas, solid tank; according to the pressure grade, can be divided into two categories of ATM tank and pressure tank; According to shape of vessel, can be divided into three categories of horizontal cylinder tank, vertical cylinder tank, rectangle tank; And PVC/FRP, PP/FRP, PVDF/FRP composite tanks.
Sectional Plastic Water Tank including three parts:
(1) FRP panels ( Bottom panel, wall panel, roof panel and manhole)
(2) Internal parts ( Internal ladder, tiepiece, support, tiepiece board, flanges)
(3) External parts ( External ladder, angle iron, tie piece board, bolts and nuts, water level indicator)
The material of internal and external parts as follows:
Stainless steel 304 /316
Hot dip galvanized steel (HDG)
Cold dipped galvanized steel (CDG)
