Tecnoseal Magnesium Unthreaded Plain Rod Anode Ø145 × 100 mm

Tecnoseal 00621/1MG Magnesium Plain Rod Anode Ø145 × 100 mm

The Tecnoseal 00621/1MG is a magnesium plain rod anode listed in the manufacturer's Plain Rods (Barrotti Non Filettati) range. Featuring a solid, cylindrical and unthreaded construction, this rod is supplied with a nominal diameter of 145 mm (5.71 in) and a length of 100 mm (3.94 in).

Manufactured from magnesium, the Tecnoseal 00621/1MG is intended for use as sacrificial material in suitable galvanic corrosion protection systems. When correctly incorporated into an installation with appropriate electrical contact, magnesium can corrode preferentially to help protect electrically connected metallic components.

The rod has a manufacturer-listed weight of 3.00 kg (6.61 lbs). Its plain cylindrical configuration does not incorporate an external thread, distinguishing it from threaded rod products. The suitability of the component depends on the required dimensions, mounting arrangement and operating environment.

Technical Specifications

Plain Rod Construction and Dimensions

The Tecnoseal 00621/1MG belongs to the manufacturer's range of plain, non-threaded rods. Its cylindrical body is specified by two principal dimensions: the rod diameter (Ø) and its overall length (l).

• Rod diameter (Ø): 145 mm (5.71 in).
• Rod length (l): 100 mm (3.94 in).
• Weight: 3.00 kg (6.61 lbs).
• Material: Magnesium.

The manufacturer identifies the product as an unthreaded rod. A specific mounting system, fastening arrangement or machining tolerance is not provided in the available catalogue information.

Magnesium Sacrificial Corrosion Protection

Magnesium is an electrochemically active material used in sacrificial anode systems. When an appropriately designed magnesium anode is electrically connected to metallic components requiring protection and exposed to a suitable electrolyte, the magnesium corrodes preferentially, helping reduce galvanic corrosion of the protected metal.

Magnesium sacrificial anodes are generally used in freshwater corrosion protection applications. The suitability of the Tecnoseal 00621/1MG for a particular system should be established according to the operating water conditions, electrical continuity and corrosion protection requirements.

Application and Installation Considerations

Before selecting the Tecnoseal 00621/1MG, verify that the specified diameter of 145 mm and length of 100 mm correspond to the intended installation.

The available manufacturer data confirms the material, unthreaded rod construction, dimensions and weight but does not identify a specific vessel model, equipment manufacturer or mounting system.

Any installation or modification of the rod should therefore follow the requirements of the relevant corrosion protection system.

Inspection and Replacement

Magnesium sacrificial anodes should be inspected periodically as part of the maintenance programme for the equipment being protected. Their condition should be assessed for material consumption, physical damage and the integrity of the installation.

Replace the anode when the sacrificial material is significantly depleted or when its condition no longer meets the requirements of the corrosion protection system.
