	Technical Details

Polypropylene tanks are designed on "rita" program module being introduced to india by arvind anticor incorporates latest advances in thermoplastic now being widely adopted by european countries.

PP tanks are welded as per standard DVS 2225 laid down by german welding society.

Anticor pp tanks have been internationally recognized and approved during "Wire & Tube 2004" exhibition held in dusseldorf germany and china.

Average tank life is 15 to 20 years.

ARVIND ANTICOR LTD.

Arguments for selection of "anticor" pickling system & tanks & fume scrubbing exhaust system.

Anticor offer world class tanks designed on "rita" engineering program module being introduced to india by "anticor"

Tanks manufactured with world class manufacturing process with european technology. Tank have been internationally recognized and approved during "wire & tube" 2004 at dusseldorf germany and china.

Tanks are welded with most modern reliable welding technology assures ( butt fusion press and hot gas extrusion process ) superior welding integrity.

Anticor have their staff trained aboard to get first hand welding technology.

"Anticor" polypropylene tanks are reinforced by massive steel support structure to enable tank load up to 10 tons.

Anticor tanks are inspected & tested in terms of hydro test. High frequency spark test, vacuum leakage. Welding joints are subjected to 3 point bend test and impact resistance test.

Anticor has capable.

City of producing tanks up to 50 meters long.

Welding is carried tanks up as per DVS 2225 standard laid down by german welding society.

Anticor is first company to introduce automated hot gas extrusion and fusion welding technology in india.

Anticor has produced some of the longest polypropylene tank in the world made out from 50 mm thick polypropylene.

Anticor has produced more than thousand of tanks of different sizes & variety.

Anticor organization is employed with 80 trained skilled personnel enjoy working in 2200 sq mtr of sprawling most modern state-of-the-art factory at ahmedabad.

Average life of anticor polypropylene pickling tanks are 15 years.

Stress normalization is carried out after the thermoradius and welding process against stress fatigue failure ensure longer life.

Pickling process know how and technology are offered to our customers.

Anticor have after sales service department and have done services at customer premises.

Environmental issues are extremely important to us at anticor family and therefore anticor offers fume extraction and scrubbing system to customers.

Introducing first time in the world the thermoplastic surface fusion technology combined feature of thermo bending for manufacture of weldless radius at corner in tank modules to enhance mechanical strength.

Comparison of Welding Process

Extrusion Welding	Butt Welding(Offered by Anticor)
Air bubble formation is possible in welding	Bubble formation is not possible
There is introduction of 3rd material in the process	There is no 3rd material required in process
Corrosion resistant to wide range of chemical	Corrosion resistant to limited range of chemical
Heating of material causes stress in P.P.	Stress free welding
Manual process skill of welder is required	Automatic process butt fusion welding is done on automatic machine. No human error/ skill is not required
Weld line can take moderate mechanical load	Weld line can take very high mechanical load
Strength of welding depend on welding rod (3rd material)	Same strength of parent material can be attained
Mobile welding equipment	Stationary welding equipment
Weld joint having three materials	Homogenous one weld joint durable as basic material
Extrusion welding is performed to obtain joint	Butt welding is performed to obtain larger sheet (joint is not visible)
Weld line protruding	Weld line flushed - smooth
Need operator expertise	The welding process is faster and less dependent on operator expertise
Repeatability is questionable	Fully repeatable welding process
Weld joint done gradually	Weld joint done in one go
Strength of welding is questionable due to additional of 3rd material (welding rod)	Strength of welding as of parent material since there is no welding rod.
Average life of tank 06-08 years	Average life of tank 15-18 years.

Comparisons of P. P. Tanks V/s MS / PP + FRP

P.P. Tank	M.S. / P.P. + FRP
Reliable extrusion welding process (Imported from germany)	Hand laying manual process and therefore not reliable
Better longer service life	Limited service life
Corrosion resistant to wide range of chemical	Corrosion resistant to limited range of chemical
P.P. is easily can be identified	Resin grade and quality brand is not easily identifiable
Liquid do not get absorbed by P.P.	Liquid get absorbed in to resin
There is no dual lamination 33in P.P.	Expansion / contraction rate between FRP & ms is different and therefore looses adhesive bonding
Does not get damage while loading	Gets damage during loading the material
Economical	Costly in long run
No maintenance	Need recoating
No need of surface preparation	Need sand blasting to ms prior to coating
No contamination in chemical solution during operation	Iron get contaminated with chemical solution during operation
Heat loss is lees compared to M.S.+ FRP (Hence save energy)	Heat loss is more compared to pp tank

Comparisons of Rubber Lining Against P.P Tank

Rubber Lining Thickness range is 4 MM to 8 MM	Polypropylene is not lining and therefore Polypropylene thickness range is 10 mm to 40 mm
Lining is done manually and therefore it has human error.	Welding is automatic and there fore it is reliable.
Life 5 to 7 years.	Life 15 to 20 years
Ageing of rubber lining happens resulting in to cracking, rigidity of rubber, brittleness which gives failure.	Polypropylene have no ageing effect.
During leakage of lining iron get dissolved and liquid get contamination, M.S. tank get corroded.	Polypropylene tank does not have iron tank. leakage can be seen no iron contamination, no corrosion.
Locations joint failure in rubber lining is difficult.	Locating leakage is very easy.
Ms rubber lined tank is heavy in weight.	Polypropylene tank are lighter in weight and they are mobile.
Rubber is lined and they are lined in ms tank.	Polypropylene is not lined in tank. Polypropylene itself is tank in mild steel skeleton frame.
Rubber has porosity.	Polypropylene is solid and non porous material.
Rubber is soft material.	Polypropylene is hard and rigid material.
Easily get damaged.	Very difficult to get damaged.
Virginity of rubber is questionable.	Polypropylene can be easily identified and tested for virginity.
Surface preparation and clean Surface is crucial for adhesion.	Polypropylene is not being adhered to M.S. tank
Joint blistering is common problem.	There is not overlap joint. no blister.
Require full support of mild steel.	Polypropylene require only skeleton frame.
Disbanding and airpocket is a regular problem.	There is no bonding, no air pocket in Polypropylene welding.
Rubber is bonded by adhesive.	Polypropylene is not bonded by adhesive. tank is made out of p.p.it self
Sand blasting can not be compromised.	Sand blasting not required.
Heat loss missed	Heat loss is very less.
It require regular maintenance	It is maintenance free.

Comparisons of P.P. Tank & A P Brick Lining Tank

P. P. tank	A.P. BRICK LINI
PP is solid	Bricks are porous
P.P. does not leave loose particle	Brick always leaves loose particle
Welding joint by p.p only ( same )	Joint material is not known
Welding is done by hot gas extrusion process	Joint is manually done and therefore not reliable
Testing / inspection is possible	Testing is difficult ( only by level )
Leakage is not possible	Floor & walls guest wet & socked with acid & chemicals
Leakage can be seen	Due to leakage finding leakage locations difficult
Welding is done once-no service is required	Regularly rejointing to be done service is required
P.P. does not get socked with liquid	Bricks consume liquid by socking
P.P. is clean & neat	Bricks are messy
P.P. joints are homogeneously welded	Joints get damaged ague expansion during heating
P.P. tanks can be moved relocated	Brick tanks can not be moved & relocated
