About AIC

• AIC is basically an engineering company who are
  into manufacturing of COMPOSITE PRODUCTS, COOLING
  TOWERS, OZONIZATION, LIQUID HANDLING SYSTEMS.
  AIC has a wide experience of 22 years and are
  pioneers in developing any product which requires
  reverse engineering.
• AIC takes technical assistance from institutes
  like IIT, UDCT, VJTI whenever any new product
  has to be developed which requires reverse
  Engineering and such association helps AIC to
  solve any type critical problems.
• AIC due to its ever growing vision and product
  development aic introduced liquid handling
  systems (loading arms) for handling various
  liquid, chemicals, petroleum products, etc. All
  advanced countries are using such systems for
  handling liquid and getting inspired looking at
  those systems we have introduced this system in
  the country.

Conventional systems

• Normally hoses are being used for handling
  liquids chemicals, petroleum products, etc. But
  such systems have many limitations
• Limitations
• Hoses after a couple of months wear out and
  starts leaking.
• Low operational efficiency.
• Bulky in handling.
• Increases environment pollution.
• Min. Two persons are required for handling the
  hose.
• Lot of spillage.
• Low life, less efficiency, it becomes awkward for
  the hoses to handle bulk quantity of fluid.

What are Loading Arms?

• Its a system consisting of rigid pipes connected
  together with swing joints to obtain better
  efficiency in loading unloading of liquids both
  in terms of time and money.
• Transferring of liquid products in to Tank
  Trucks, Rail wagons, barrels carboys from a
  fixed source by pipe to filling or unloading
  point that may park in any position.
• Loading Arms Consists of the following
• 1. Primary Arm 2. Secondary Arm 3. Drop
  Pipe 4. Swing Joints 5. Balancing Unit. 6.
  Other accessories as per customers requirement.

Why loading arms

• Looking at the above limitations of hoses loading
  arms have following advantages
• Its the most efficient and reliable way of fluid
  handling both in terms of time money.
• Longer life.
• Reliable and rugged alternatives to the hose.
• No spillage.
• Easy to maintain.
• Available in variety of material.
• Filling cost is reduced.
• Increases productivity and decreases labor cost.
• Environment friendly.
• Hazardous liquids like Oleum, Sulphuric Acid,
  Liquid NH3 etc can be easily handled by Loading
  Arms in comparison to Hoses.

Heart of loading arm

• SWING JOINT Swing joints are used for
  flexibility in movements and leak free operation
  at high pressure and temperature. It consists of
  the following
• 1. Ball bearing built in to the housing with high
  precision clearance.
• 2. Special o ring seals are used to ensure
  retention of the lubricants and exclusion of
  pollutants.
• 3. Main seal which is lip type. M.O.C of the seal
  is selected based on the liquid being handled.
  The design of seal is such that it mates with the
  surface during operation and gives excellent
  sealing function. Mating surface is precision
  machined.
• 4. We manufacture following types of SWING
  JOINTS. a. Two Piece Swing Joint b. Three Piece
  Swing Joints. Customization of the swing joints
  is possible depending on the application.

Balancing unit

• To stabilize the loading arm at it parking,
  loading or unloading positions the spring
  balancer are used.
• The spring balancers are basically used to
  balance the entire system of loading arm in order
  to make it user friendly.
• Balancer can be of different types depending upon
  the loading arm size.
• 1. Single Spring Type Balancer 2. Double Spring
  Balancer 3. Pneumatic Balancer.

Types of loading arms

• Selection of the type of loading arm to be used
  depends on the Tanker which has filled or
  unloaded. Nowadays tank truck comes with the
  fittings which determine whether it is for Top
  Loader or Bottom Loader/Un loader.
• TOP LOADING ARMS
• Top loading arms are normally used where
  the liquid has to be filled in the tank truck,
  rail wagon from top. Its available in
• variety of forms depending upon the
  application and site conditions.
• BOTTOM UNLOADING ARMSBottom unloading arms are
  used where the liquid from the tank truck or Rail
  Tanker has to be unloaded or Loaded. Such
  unloading arms are generally used where Railcar,
  Chemical Transport offloading and aircraft
  refueling.

Bottom loading arms

• Bottom loading arm pictures will be sending to
  you by email. Make provision for 2 pictures.
• Bottom Loaders
• Bottom loading systems offer numerous benefits
  over conventional top loaders.
• Safety is the prime advantage since the operator
  remains on the ground, not on
• top of the truck where falls are a common threat.
  Bottom loading connections are made more quickly
  so overall loading time is reduced.
• Bottom loading creates less turbulence in the
  tank, reducing the danger of generating static
  electricity. Bottom loading not only reduces
  vapors which can be an environmental hazard, but
  this system can also be easily adapted to fully
  recover vapors displaced during loading.
• Speed is a key advantage of bottom loading
  because tanks can be filled faster and a number
  of compartments can be loaded simultaneously.
  Bottom loading islands are simpler and cheaper to
  build than top loading racks. Maintenance time is
  also reduced. You can realize more savings
  because you'll safely load more material in a
  shorter time with less spillage and vapour loss.

Testing of loading arms its components

• Generally following tests are carried out on the
  loading arm its components during manufacturing
  of the loading arm
• Chemical analysis of all the components as per
  standards
• Ultrasonic testing to ensure leak proof
  operation. This is specially done on elbows,
  pipes, flanges etc. As per ASTM SA 388 AND ASTM
  SE 213
• Hydro testing of seals, orings, swing joint.
• Final hydro testing of the assembled loading arm.
  Hydro testing is done at 1.5 times the designed
  pressure for the whole day continuously.
• Welding is done as per asme v article 2 asme ix.
  We maintain WPS and PQR for welding.
• All weld joints undergo radiography test.

17
Quality assurance sizes of loading arms
available.

• A detailed QAP is made before we start the
  manufacturing of the Loading Arm and the same is
  sent to our clients for approval.
• Welding process meets all the requirement of
  section IX of the boiler and pressure vessel code
  of ASME II and are radiography tested.
• SIZES Loading Arms are available for various
  line sizes ½, 1, 2, 3, 4.

Future prospects

• AIC is well planned to launch its new series of
  Loading Arms which will specially go for marine
  applications.
• These loading arms will have size ranging from 6
  to 16 Dia. These system require special
  hydraulic and pneumatic system for its operation.
  We are working and developing the same in full
  swing. We expect to launch the same in near
  future. You can see the model picture of the
  Marine loading arm below.
