CHEMICAL AND PETROCHEMICAL INDUSTRY

In the chemical and petrochemical industries, gases, fuels and vapours are often emitted during manufacturing, processing, transporting and storage of flammable products. These products cause wear, erosion, corrosion, abrasion, leaks and deteriorate the assets. SealXpert Products are specifically designed to be compatible to a wide range of chemicals operating various temperatures. Our engineered cold repair solutions are useful for repair works in these hazardous areas with repair methods being compliant to ASME PCC2 and ISO 24817 standards.

CARBON STEEL LEAK AT VALVE BODY

Leak was discovered at a valve body of a steam system.Firstly, the pipe surface was cleaned and roughened. Next, SealXpert Teflon tape and SealXpert Stainless Steel Pipe Clip were applied around the leak area. Thereafter, PS108 Hi-Temp repair putty was applied around the affected area. Finally, Wrap Seal PLUS Fiberglass Repair Tape was applied to reinforce the repaired area.

LEAK AT WELD JOINT ON STAINLESS STEEL PIPE

A 1” elbow joint and a 6” x 1” reducer weld joint was leaking condensate steam in a process plant. At the reducer, the pipe was nearly severed with through-wall penetration of more than 50% and the vibration is very severe.Leak was arrested with using clip and Seal Stic steel epoxy. Next, Wrap Seal fiberglass tape was applied over the repaired surface for reinforcement.

CORROSION OF TANK CONNECTION & FLANGE

The tank connection and flange of Hydrochloric acid tank is subjected to corrosion and thinning.Firstly, the pipe and tank surface was cleaned and roughened. Next, Wrap Seal PLUS resin & activator was applied onto the pipe and tank surface and reinforced with SealXpert Chopped Strand Mat. Thereafter, a galvanized sheet metal box-up was created to fill in the Wrap Seal PLUS resin & activator. Finally, Wrap Seal PLUS Fiberglass Repair Tape was applied to reinforce the repaired area.

CORROSION AND WEAR OF PUMP SLEEVE

The pump sleeve and impeller seat is experiencing heavy wear and corrosion from the pipe medium and requires repair and maintenance once every 2 months. After applying SealXpert WR204 wear resistance coatings, the downtime for this pump has reduced and asset integrity and reliability has improved tremendously.
