The present invention provides a tubular member and a burner with a tubular member that is capable of improving the flavor of a food product having undergone roasting treatment. A tubular member that is a part of a burner with a tubular member is attached to a tip of a gas burner, and has holes through which the combusting flames pass. This configuration eliminates gas odor from a food product having undergone roasting treatment. Thus, the flavor of the food product having undergone roasting treatment can be improved.

A handheld welding torch apparatus for welding in confined areas includes a gas tank having a handle portion and an extension portion. Each of the handle portion and the extension portion is cylindrical. A valve assembly is coupled to the gas tank and comprises a tank receiver, a tube stem, a valve housing, and a control valve. The tube stem is coupled to the tank receiver. The tube stem is in fluid communication with the gas tank when the tank receiver is engaged with the extension portion. The valve housing is coupled to, and in fluid communication with, the tube stem. The control valve is coupled within, and in fluid communication with, the valve housing. A tube neck is coupled to, and in fluid communication with, the control valve. A welding tip is coupled to the tube neck.

A torch extension used for home barbecue, comprising a tubular body with a cylindrical shape and a connection head, the tubular body and the connection head are integrated, the tubular body has a rear inlet connected with the connection head and through which a fuel enters the tubular body to create a flame when the fuel is ignited. A diffusion trajectory of the flame in the tubular body with a cylindrical shape is basically conical, an interior part of the tubular body keeps a certain distance from the flame, and the frame has an increasing cross-sectional area with the diffusion of the flame.

A welding torch having a nozzle assembly with multiple attachment methods is disclosed. The nozzle assembly includes a nozzle shell, an electrically insulating sleeve, and a nozzle insert. The nozzle insert is configured for attachment to gas diffuser assemblies with different attachment mechanisms (e.g. a slip-on mechanism relying on frictional force, and/or screw-on mechanism relying on torque).
