Application Profile Repair Don’t Replace! • PROBLEM: • Many ships that have reached over 10 years old will suffer from the BALLAST TANK TRANSFER PIPES becoming corroded, damaged, highly worn surfaces. • This PROBLEM requires in most cases that PIPES be REMOVED and REPLACED at a high cost to the ship owner. • This process usually has to take place in a DRY DOCK situation which in itself can ADD further to the HIGH COST • Description: • A ballast tank is a compartment within a boat or ship, that holds water. A vessel may have a single ballast tank near its centre or multiple ballast tanks typically on either side. A large vessel typically will have several ballast tanks including double bottom tanks, wing tanks as well as forepeak and aftpeak tanks. Adding ballast to a vessel lowers its centre of gravity, and increases the draft of the vessel. Increase draft may be required for proper propeller immersion. • The COST of this problem area in BALLAST TANK PIPE WORK can vary dramatically BUT will nearly always involve HARD TYPE repair (i.e. PIPE REPLACEMENT) methods or REPLACEMENT that has to be carried out in EXPENSIVE DRY DOCK TIME. • Unique Polymers can offer a EXTREMELY COST EFFECTIVE solution to this problem that not only can offer LONG TERM protection but can also be CARRIED OUT WHILST AT SEA - No need for expensive dry dock visits and LOST PROFITABILITY. • The REPAIR is QUICK - EFFECTIVE and SIMPLE to carry out by on-board operatives. • SOLUTION: • The following pictures show a typical BALLAST TANK PIPE repair on board.

Application Profile Repair Don’t Replace! • Fluid Flow Equipment suffers from erosion from day one in operation. This erosion will compromise the efficiency of the PUMP and increase the amount of energy required to power the unit. • Even WEAR resistant materials will eventually wear away. The ABRASIVE PARTICLES in erosive applications will wear away the protective oxide layer and subsequently wear away the base material. If temperature and chemicals are also part of the application - then the wear can be significantly accelerated. • If this cost is them multiplied by the number of pump units within the facility - increase in power consumption can be significant. • With the added problem of CORROSION in the cases of ABRASIVE applications - this can also add to the burden of the PUMP MOTOR. • This cause and effect problem can mean that the PUMP VOLUTE and IMPELLER being replaced on a regular basis. • To COMBAT these difficulties - there are a series of HARD CERAMIC ENGINEERING GRADE PRODUCTS available. • UPS200- CERAMIC CARBIDE WEARING COMPOUND / Ideal for REPAIRING erosion/corrosion damage on all types of FLUID FLOW equipment • UPS205- ABRASION RESISTANT CERAMIC CARBIDE FLUID - Ideal for prevention erosion/corrosion damage on all types of fluid flow equipment. • UPS240 - Extreme abrasion resistant heavy duty lining material for use in highly abrasive situations in all fluid flow equipment. • Products Used UPS200 – UPS205 – UPS105 – UPS240

Application Profile Repair Don’t Replace! • Many problems can occur and lie in wait for unsuspecting industrial accounts when the pipe carrying production fluids start to leak without any notice • This happens when the pipes are covered / protected by lagging systems that HIDE the condition of the underlying PIPE. • Moisture can ingress through the lagging and start interacting with the pipe metallurgy and can cause pitting and rusting that can eventually turn into leakage paths through the pipes. • As the lagging material covers the pipe in total - no visual warning can be seen of this impending serious problem. • Unplanned leakage and pipe breakdown can in most cases cause major disruption in the plant process and its ability to function in either manufacturing or service supply. • To elevate this problem - there has been developed a WATER BASED - SINGLE COMPONENT - Elastic property polymer UPSTTLG that combined with UPSTTLG Reinforcing Sheet can offer total protection against under lagging corrosion and at the same time offer some abrasion and impact damage protection for the lagging covering the pipe. • The UPSTTLG product is a HIGH PERFORMANCE polymeric coating designed to encapsulate and protect all types of pipe insulation materials and dangerous asbestos fibre from exposure to the air. • Is designed to offer MAXIMUM PROTECTION against UNDER INSULATION CORROSION in the most aggressive of environments. Is a colour stable and flame retardant product that supplies optimum levels of adhesion, impact resistance and durability in all types of weather. • Remains FLEXIBLE at temperatures of -30'C t0 160'C. • Is extremely easy to use, and promotes excellent resistance to fungal and algal growth.
