The activities of the oil and gas industries include complex environments that require coatings with very high properties. There is severe corrosion and abrasive environments along with mechanical and thermal factors in these processes. The range of these environments varies from moderate conditions to extreme and very harsh conditions. Many existing coatings have serious limitations and are not suitable for use in oil and gas industries. Coatings improve the mechanical properties of the part such as hardness, strength and toughness.

The four major problems in the oil and gas industry are corrosion, erosion, fatigue and wear, which can increase resistance to these phenomena by choosing the right coating.

Some parts for repair and reconstruction in this area by thermal spraying method:

• Pump components such as shaft, plunger and impeller

Shaft, plunger and impeller are expensive components of the pump, so their damage should be prevented. HVOF thermal spraying process is used to protect them against wear, rust and corrosion.

• Seat and Gate Valve

Gate valves are one of the widely used valves used in the oil industry, which are severely subject to wear and corrosion due to the presence of abrasive particles in the extracted oil. Using the thermal spraying method, hard and wear-resistant and corrosion-resistant carbide coatings such as tungsten carbide are applied on them.

• Seat and ball valves

Ball valves are one of the most widely used valves used in the oil industry, which are severely subject to wear and corrosion due to the presence of abrasive particles in extracted oil. Using the thermal spraying method, hard and wear-resistant and corrosion-resistant carbide coatings such as tungsten carbide are applied on them

• Boiler pipes
• Extruder
• Compressor plunger
• Gate valve seat and gate
