Rangoli Fibre Reinforced Private Limited

Reaction vessel and mixing vessel with agitator is requirement in number of processing operations. Both heat and mass transfer are greatly influenced by agitation of mixing.

Process conditions range from -5 to 150 deg C, from pH 1 to pH 12 and operating at 1kg to 10kg pressure, the vessel design was enhanced for 5,000 cycles. In the various stages of production, the service of the vessels involve dissolving and reacting raw materials and crystallising final product.

The selection of Thermo , Fluoro plastic liner and resin system required careful investigation to ensure that the resin system was suitable for the thermal shock. GRACE ™ [RANGOLI] worked very closely with the customer’s engineers providing them with test data to substantiate their selection of materials.

These vessels will be Manufacturing & Fabrication with material of construction like FRP (FRB, FRVE, FRSVE.) and Dual laminate like PP/FRP , PVC/FRP , CPVC/FRP , PVDF/FRP , ECTFE/FRP , ETFE/FRP , FEP/FRP and PFA/FRP.

We can design, manufacture and supply of Peddle, Propeller, Curved Turbine, Pitched Turbine, Anchor and Cowl types agitators for specialized applications suited to process and operating conditions.

Material of Construction can be offered in various grades of thermo plastics such as PP. & HDPE. We also provide carbon Steel agitators with special type of coating and linings including FRP., PP., HDPE., PVDF., FEP. and PFA. etc.

Implementation of design in manufacturing is most crucial in case of such Equipments as the sequence of Fibre Glass & external, internal stiffening ribs is a very Important Factor in working of such Pressure / Vacuum Vessels. We have Designed & Manufactured vessels for full vacuum & up to 10 kg / sq. cm working pressure.

VACUUM FILTER NUTSCHE
A vacuum filter nutsche is one of the simplest batch filters. It is a open tank with a Perforated plate fitted inside having filter cloth as filter media. Perforated plate is having a suitable perforation to pass the filtrate. The slurry is fed into the filter vessel and separation of mother liquor from the slurry. Cake will form on perforated plate, which can be removed manually. If required, cleaning and washing of the filter nutsche can be done easily before starting a new batch. The Filters Nutsche can be offered up to operating vacuum of 720mm of Hg. The filter nutsche is very frequently used in Process plants industries .

The largest capacity PP/FRP. Vacuum filter nutsche supplied and commissioned by GRACE™ [RANGOLI] is 15,000 Liters to Anchor Daewoo Industries Ltd. & Jay Chemicals.

PP/FRP pickling tanks are offered with specially designed lip type Hood for fume collection from the sides of the tank. This kind of hood is suitable for the batch pickling operation for continuous pickling operation. Hood can be offered in top mounted and of any suitable shape like rectangular, semi arch or canopy types.

We also offer pickling tanks with suitable hood and fume scrubber with centrifugal exhaust fan, ducting network, stack or chimney and with re-circulation pump for scrubber with piping.

FRP and dual laminates pipe is often the material of choice for corrosive process systems. The factor included in this are:-

An ability to be tailored for a wide variety of corrosion resistant conditions
Light weight (less than 20% of steel, 10% of concrete)
Excellent strength to weight (stronger than steel on an equal weight basis)
Low coefficient of friction (>25% better than steel)
Good dimensional stability
Low thermal conductivity (saving insulation costs)
Low long-term maintenance costs.

The total cost of the system includes all the above-mentioned variables. The cost of saving for the FRP. and dual laminates pipe VS the steel has even greater cost saving over alternative alloy constructions.

All these piping & fittings can be manufactured and Fabrication in FRP (FRB, FRVE, FRSVE.) and Dual laminate like PP/FRP , PVC/FRP , CPVC/FRP and PVDF/FRP. Depending on reacting chemicals & temperature conditions.

Our concerns for the long term performance of your pipe system means that our specially trained customer oriented experts and technicians are able to advise on any aspect of site installation. Our specialist go to your site to carry out all functions relating to facility and component assembly, set-up, testing, putting into operation and more.

GRACE™ [RANGOLI] have supplied the blower having flow rate capacity of 20,000 m3/hr. MOC. PP/FRP. To M/s. PRESTRESS WIRE IND. LTD. & 15,000 m3/hr to M/s. UNIMARK REMEDIES LTD.

The amount of static pressure developed depends upon the ratio of the velocity of the air leaving the tip of the blades. Operating efficiency of fans ranges from 40 % to 70 %. The performance of the centrifugal fan varies with changes in conditions such as temperature, speed and density of the gas being handled.

GRACE™ [RANGOLI] can design and manufacture Blowers with different volumetric capacities and negative pressures are offered. Blowers at the optimum RPM, including blade designs / angles which insures best efficiency and hence least power consumption with minimum maintenance. The Unique feature of FRP Molded impeller is that it is light in weight which minimizes the all usual blower's mechanical problems.

A complete Fume Scrubbing System can be designed to handle a gas flow up to 50,000 m3/hr with power rating up to 100 h.p. A higher gas flow rate can also be designed. Impeller of the blower is dynamically balanced at 3000 r.p.m. The shaft design is EN-8 with FRP sleeve. The bearings used will be self aligned 'SKF' or 'FAG' or any other standard make. The electric motor will be of 'Crompton' or other equivalent make.

GRACE™ undertakes the manufacturing at their well laid works or at the job site as per the requirements. One of the activities of GRACE™ [RANGOLI] is to provide anticorrosive Coating using the materials like Fiber Reinforced Plastic (FRP), Fiber Reinforced Bisphenol (FRB), Fiber Reinforced Vinyl Ester (FRV) and Fiber Reinforced Superior Vinyl Ester (FRSV).

These Coating are particularly used to protect the metallic vessels against corrosion due to acidic or alkaline reactions in the chemical storage tanks, rotating equipment, reaction vessels, filters, ducts and scrubbers. It can be applied to existing and new equipment. The total engineering support is to be provided to the customer for the selection of material for the Coating.

It has many advantages over other lining methods like rubber lining. Some of the advantages are :

Much stronger bond to metal.
Longer service life.
Seams can be avoided and thereby safer protection afforded.
Coating with F.R.P. can be done at room temperature unlike rubber lining which require vulcanizing.
Easily create on site.
Very little maintenance and ease of repair.

By grace of god and our well wishers we have period of being a successful solution for multifarious complicated jobs. The experience have invited us as an ultimated solution for anything which other many say impossible.
