Products : FRP Tanks

 

We manufacture large diameter FRP tanks by filament winding techniques. These tanks have higher laminate strengths than conventional contact moulded tanks. Also, by virtue of filament winding, the FRP layer sequence generated, exhibits optimal material characteristics as per design requirements, thus lowering raw material costs and consequently producing lighter, stronger and cheaper products.

Tanks are generally designed as per BS 4994 guidelines. However, customer's specification forms the sole basis of designing and testing FRP Tanks.

HISTORY OF FRP TANKS

Early Underground Petroleum Storage Tanks in Europe and USA were made of steel, some with an external coating, and others without it. After some years of service, it became apparent that many of these steel tanks were leaking, inspite of having a supposedly adequate protective coating. Studies showed that almost 27% of steel tanks, even after protective coating, were leaking after 15 years. The cause of the leaks was attributed to a wide variety of metal corrosion.

The Environment Protection Agency (EPA) of the USA introduced strict regulations to protect tanks from polluting ground water resources. This led the American Petroleum Institute (API) to facilitate development of corrosion resistant FRP Tanks and to encourage its use in the USA .

With the passing years, FRP has emerged as the favoured material of construction for Underground Storage Tanks, globally. By 1988, CHEVRON had replaced and upgraded 75% of their steel tanks with FRP Tanks. By 1989, MOBIL OIL had replaced 90% of their steel tanks with non-corrosive fiberglass. Studies show that FRP Tanks installed 30 years back in USA are giving trouble-free service even in highly corrosion-prone areas.

Indian soils are reported to have one of the highest soil corrosivity in the world. Replacement of all underground steel tanks with FRP Tanks is an eventuality. FRP offers immense potential and great advantages as the material of construction for Storage Tanks.

In India , the oil and natural gas industry has now started embracing this global trend, with new Underground Petroleum Storage Tanks being made in FRP. Also, older tanks are being replaced by their FRP counterparts.

ADVANTAGES

Corrosion Resistant
Maintenance Free
Long Service Life of over 50 years without replacement or maintenance
Safe for Environment
Light Weight – Easier Handling
Smooth Inner Surface – Lower Sludge Formation, Lower Cleaning costs
Leak Proof – Saves Material Loss

NOZZLES

All nozzles for our FRP Tanks are FRP Flanges, integrally moulded with the FRP Tank body. Flanges are fabricated as per numerous Bolt Dimension Systems like ASTM, DIN, JIS, BS etc. as specified by client.

INSTALLATION

FRP Tanks, being light in weight, offer great advantages for material handling. They require handling equipments of considerably lower capacity, thereby easing installation. Further, they require lighter foundation and thus help reduce overall costs. Once installed, they are virtually maintenance free.

REPAIR

Repair of FRP Tanks for Transit Damage or Damage due to poor handling can be easily carried out at site in a very short notice, by our skilled site teams.

APPLICATIONS

Potable Water Storage Tanks
Underground Petroleum Storage Tanks
Chemical Storage Tanks
Large Capacity Panel Tanks
Mobile Tanks mounted on Trailers
High Pressure Light Weight Cylinders (upto 200 kg/cm 2)

EXPERIENCE

 We have supplied numerous FRP Sump Tanks and FRP Aboveground AFFF Storage Tanks to IOCL Pipelines and they are all in satisfactory operation till date.

 We have manufactured and Pressure Tested 2 M Dia FRP Tanks upto 10 kg/cm2 (g) for Indian Military Applications.

 We are registered with Engineers' India Ltd. (EIL) as approved manufacturers of FRP Tanks.

We are approved vendors for oil majors like IOCL and ONGC

 FRP Tanks of capacities as large as 77 KL have been fabricated in symmetric sections, transported to site and assembled there with ease.

  FRP Tanks of capacities as large as 50 KL have been fabricated at our works and have been safely exported to Nepal. These tanks are currently opearating successfully.

 Similarly Rectangular Panel Tanks of capacities ranging from 1 M3 to 1200 M3 can be fabricated in rectangular panel sections, transported to site and assembled there.
