Emergency repair of a Leaking Pipeline

Challenge - Emergency repair of a leaking pipeline- carrying chemicals, steam, gases etc.

Solution: Wrap the sealing tape around the leaking area

A strong  tape which bonds without adhesive. It is applied with tension by wrapping the tape around itself.
The bondage of Anagha IST on its own backing creates a water tight, permanent
sealing. No drying time is required. Its flexible material can be applied smoothly
on any kind of surface, including wet or warm, dirty or oily. Extreme conditions
can be used also for temporary applications leaving no residues after removal.
The tape can even be applied under water. It has an excellent resistance to
various chemical substances, oils, acids, solvents, salt water, UV radiation and
extreme temperatures. 

Instant repair made easy of leaking pressure pipes, hoses, connections,
exhaust systems (gases, hot and cold water, acids, liquid fuels, vapor).
• Pipes
• Irrigation systems
• Hoses
• Sprinkler systems

Instructions
1. Remove sharp edges from the surface that could damage the
tape under tension.
2. Remove the interleave .
3. Apply tape at maximum tension.
4. Wrap with 50% overlap.
5. Start wrapping next to the area to be sealed.
6. Wrap over the leak until the flow is stopped.
7. Then progressively expand the wrapped area, wrapping back
and forth. Continue until the total coverage is equal to the
diameter of the pipe, either side of the leak area.
8. Wrap a final layer with minimum tension.

How to solve rust problems at affordable costs ??

CAN WE HAVE A PERMANENT CURE  AGAINST RUST AT AFFORDABLE COSTS

Metal surfaces getting rusted is a common occurring . Also we have accepted that this phenomenon cannot be eradicated . So the logical solution is to clean the surface from rust, apply primer and then paint it..... and wait again for the painted surface to rust. For critical applications , Engineers use advanced anti rust coatings etc  however at high costs.

Typical challenges faced in the popular methods to handle rust are as follows:

Cumbersome , labour intensive and costly process of cleaning rust using sander/ shot blasting etc

·          High cost of protecting the metal surface if costly anti  rust coating are deployed

·         Redoing the painting or coating at regular intervals

·         Unnecessary attention required to protect from rust which could  be gainfully utilized by maintenance engineers  for larger engineering causes.

How would it be if we could treat the rusted surface, without removing rust,  such that it converts itself into a passive coating which is anti rusting , permanently.

 ‘SALVAGE RUST’ - a water based emulsion  when applied to the rusted surface reacts with the rust  and converts it into a passive coating which is anti rusting.  Depending upon the degree of rusting this coating becomes brownish to blackish layer. For aesthetics/ colour coding  it can be painted over OTHERWISE this anti rusting passive coating formed  ensures no future rusting.

                           FEATURES                                                                    BENEFITS  

Cost – Lower than traditional Painting costs.

1.    PHENONMENON OF RUSTING

R­ust is the common name for a very common compound, iron oxide. Iron oxide, the chemical Fe2O3, is common because iron combines very readily with oxygen.

Iron (or steel) rusting is an example of corrosion -- an electrochemical process involving an anode (a piece of metal that readily gives up electrons), an electrolyte (a liquid that helps electrons move) and a cathode (a piece of metal that readily accepts electrons). When a piece of metal corrodes, the electrolyte helps provide oxygen to the anode. As oxygen combines with the metal, electrons are liberated. When they flow through the electrolyte to the cathode, the metal of the anode disappears, swept away by the electrical flow or converted into metal cations in a form such as rust.

 

For iron to become iron oxide, three things are required: iron, water and oxygen.

Here's what happens when the three get together: When a drop of water hits an iron object, two things begin to happen almost immediately. First, the water, a good electrolyte, combines with carbon dioxide in the air to form a weak carbonic acid, an even better electrolyte. As the acid is formed and the iron dissolved, some of the water will begin to break down into its component pieces -- hydrogen and oxygen. The free oxygen and dissolved iron bond into iron oxide, in the process freeing electrons. The electrons liberated from the anode portion of the iron flow to the cathode, which may be a piece of a metal less electrically reactive than iron, or another point on the piece of iron itself.

The chemical compounds found in liquids like acid rain, seawater and the salt-loaded spray from snow-belt roads make them better electrolytes than pure water, allowing their presence to speed the process of rusting on iron and other forms of corrosion on other metals.

2.    HOW TO SALVAGE RUSTED PARTS AND PREVENT FURTHAR RUSTING Application of Water based polymer which reacts with rust to form a passive layer which prevents rusting.  SALVAGING RUST consists of two aspects. · In the first aspect, on application of the product to the surface of iron the rust is converted into an organo - metallic complex and passivated. · In the second aspect an elastomeric Co-polymer with cross linking compounds form a film which is impermeable to air and moisture. These two aspects stop the process of rusting of iron by converting and protecting. Depending upon the degree of rusting of the iron surface, on application of the product, the product gives rise to black, grey or brown film. Iron lower hydroxide gives black film, iron higher hydroxide gives grey film and Iron higher oxide gives brown film.

APPLICATION ·   Remove as far as possible the flaky and loose rust, old paint by the use a wire brush. The loose particles on the surface are then removed by the air wash or water wash.. Grease and oil are removed by a detergent wash followed by a water wash. Do not remove all traces of rust since it can be converted. ·   Transfer a small portion of Rust converter in a non-metallic container. After use do not pour back the unused portion to the original container, this will prevent contamination of the product. ·   Anagha Salvage Rust is an under coat and accepts all types of Top Coats like enamel, epoxy, polyurethane, polyester etc.         RECOMMENDED FOR: ·         Pharma , food Industry, Process plants  ·         Automobile Industry, Locomotives and Railways ·         Shipping Industry, Steel plants, Industrial Fabrications, ·         Chemical Plants and Structures ·         Fertiliser Industry, Soap & Detergent Industry ·         Metal Fabricators, Building RCC structures ·         Petroleum and Petro - Chemical plants ·         Port & Docks, Bridges & Dams.

3  HOW TO PROTECT METAL SURFACE  FROM RUSTING

Proactive approach to ensure the phenomenon of rusting is eliminated. Application of Water based emulsion which is hydrophobic, protects against moisture and environment.

Anagha Stop Rust contains low particle size Polymer which helps in fast film formation. This film is highly hydrophobic and does not allow air and moisture to pass, thereby stops iron from rusting and metals from oxidation.

     APPLICATION:

·CLEANING: Wash the surface free of loose particles dust, oil, grease, etc., with the help of wire brush, water and light detergent

·COATING: After the surface is dry apply one coat of  Stop Rust, allow it to dry. It dries in 15 minutes in summer and 45 minutes in winter. After the first coat is dry apply the second coat of  Stop Rust. Allow this coat to dry completely in 30 minutes. This completes the application procedure.
