Flange Integrity Management

a. Flange Encapsulation

AOTC provides solution for the protection of flanges, fastenings and associated pipe elements using a hybrid polymer encapsulating membrane that can encapsulate any size of flanged joint configurations. This membrane protects these joints by preventing crevice, galvanic and atmospheric corrosion. Our coating system is an easily peelable and re-sealable system that gives easy access to the fasteners if required.

b. Flange Face Protection and Reforming

Corrosive fluids, crevice corrosion, bimetalic corrosion, and steam can lead to deterioration of flange faces leading to leakage. Such issues if not addressed earlier can lead to breach in containment, loss of product, costly shutdown and replacement cost. AOTC provides cost effective flange face repair and protection solutions that can form perfectly mating flange faces including a theaded surface finish.

C. Flange Online Leak Sealing

AOTC's On-line leak sealing team understands the need for swift and cost effective solutions for our client's needs in avoiding production losses and unscheduled plant shutdowns. Our skilled leak sealing technicians and disciplined staff ensures that leaks are efficiently and permanently fixed in a safely manner. Their capabilities include sealing leaks in flanges in varying pressure and temperature conditions. We are continously working towards providing efficient and cost effect solutions to our clients from many industries such as Oil and Gas, Petrochemical, Energy, Manufacturing etc. Our on-line leak sealing team is available 24.7 hours to serve you.

 

Rotary Equipment Corrosion Management

AOTC's experienced engineers and technicians provide solutions to minimize the effects of abrasion, erosion-corrosion, and cavitation on fluid handling rotarory equipment while simultanenously increasing performance. Our goal is to provide solutions that also focuses on reduction in cost of downtime, extend the equipment's life and increase its efficiency. 

The services we provide are:

Pumps

  • Rebuilding cutwaters, flow straigthteners, diffuser/impeller/rotor vanes damaged fan blades
  • Application of internal coatings for repairing of erosion-corrosion damages
  • Repairing and rebuilding of holed / cracked pump cones and casings

Fans, Blowers and Compressors

  • Repairing and rebuilding of damaged fan blades, rotors, internal casing damage-holed and cracked casings, shafts, vane glades
  • Application of internal protective coatings

 

Stationary Equipment Corrosion Management System

In most industries as well as commercial complexes, corrosion is the biggest cause of stationary equipment breakdown. Over time operating conditions such as high temperature, high pressure and constant attack from corrosive chemical solutions and entrained solids create an aggressive environement that leads to futher deterioration of the equipment's health.

We specialize in corrosion management of the Tank, Vessels, Columns, HVAC systems, structures, switch gear containers many other equipments. 

Our team of expert service engineers and trained technicians have provided cost effective and efficient solutions for the protection of stationary equipment to many of our esteemed clients. These solutions result in minimized downtime and increase in the life of the asset for the client.

Thermal Spray Alluminium Coating Service (TSA)

AOTC has industrial trained and experienced technicians that specializ in in-house and in-situ thermal spray alluminium coating jobs.

Thermal Sprayed Alluminium (TSA) is a thermal spray application of a variety of sacrificial coatings for corrosion resistance, namely alluminium, zinc and a combination of the two. Thermal Spray, a process whereby a powedered or wire form of metal is melted by an energy source and sprayed onto the surface of another metal. TSA gives more corrosion control, wear resistance, traction and can be used to restore dimensions. Thermal spray coatings provide exceptional corrosion protection of steel substrates.

Our endeavor in providing cost effective and quality solutions to our various clients have led us to develop a team of trained technicians that ensure client satisfaction through effective and efficient executions.

 

Marine Corrosion Management System

Marine Vessels and Equipment face varied and severe operating conditions due to them being exposed to weather, salt water and galvanic effects that lead to corrosion. Conventional coating systems are usually not capable of preventing such deterioration of the health of the Vessels and Equipment that are also affected by cavitation, impingement and entertainment under these operating conditions. 

AOTC specializes in providing long term protection and repair solutions with fluid-grade materials for metal rebuilding and erosion-corrosion and abrasion protection for all issues faced by the marine industry.

  • Shipyards - Docs gates, overhead cranes, crawler cranes, diesel and hydraulic hammers, dump trucks, concrete mixers, dredging equipment, fenders, bollards, steel piles, multiwheel transport systems.
  • Port Facility Maintenance - Weathering damage of concrete structures, slippery transit areas, roof damage, expansion joint failurs, HVAC.
  • Cargo/Passenger Ships - BOW - Severe pitting and corrosion on bow thrusters, bulbous bows, hulls, decks, mooring winches.
