Flame Spray Gun in Oman

Flame Spray Gun

The flame spray gun simplest device has based on the principle that if a wire rod were filled into an intense, concentrated flame, (the burning of a fuel gas with oxygen), it might melt. If the flame was surrounded by a stream of gas, the molten metal would become atomized and readily propelled onto a surface to make a metallic coating. Flame spray gun process variation during which the controlled explosion of a mix of fuel gas, oxygen, and therefore the powdered coating material is employed. it melts and propels the fabric to the workpiece.

Flame Spray Gun Process

The flame spray may be a process in which a mix of oxygen and fuel like acetylene, propane, or hydrogen is injected. The gas mixture is combusted within the front of the sand blasting nozzle to make a flame external to the nozzle. the choice of the nozzle design depends on the coating material, which may be within the sort of either powder or wire. a chilly air sheath is employed to collimate the flame to regulate the spray pattern. within the powder feed system, the coating material is gravity fed to the gun from a sand blasting hopper. Aspirating gas carries the powder through the flame. The powder particles melt during transit through the flame and deposit on the substrate. within the wire feed system, the wire tip is continually fed into the flame by a roller drive mechanism. The molten material at the tip of the wire is fragmented and propelled to the substrate by compressed gas injection. The wire diameter and feed rate, air and gas flow rates, flame temperature, and pressure determine the coating properties. The deposition rates of the coating depend upon the fabric and vary between 15 and 500 g/m, with coating thickness starting from 50 to 1000 µm. Spraying processes characterized by low capital investment, high efficiency and deposition rates, and relatively simple operation and price of kit maintenance. The flame spray gun uses combustible gas as a heat source to melt the coating material. a good sort of material is often deposited in rod, wire, or powder form as coatings using this process flame spray guns and therefore the overwhelming majority of components are sprayed manually.

Flame Spray Gun Advantage

• Simple in design, and dust and fumes levels are lower.
• It is widely used for Corrosion protection of structures and machine parts (e.g. bridges, offshore platforms, LPG bottles).
• Low Cost.
