Pipe SANHA carbon steel, externally galvanized, d18×1.2 mm, 3 m section

SANHA carbon steel pipe, externally galvanized, d18×1.2 mm in a 3 m section is intended for plumbing and HVAC installations that require a galvanized steel line. The pipe has an outer zinc coating that provides external corrosion protection while the 1.2 mm wall thickness and 18 mm nominal diameter deliver mechanical strength suitable for water and heating circuits. Supplied as straight 3 m lengths, this pipe is compatible with common fittings used in fluid distribution and heating systems where a galvanized surface is specified.

Advantages

The externally galvanized finish offers durable corrosion resistance against atmospheric and moisture exposure without changing the internal bore, maintaining hydraulic characteristics for water and heating media. The nominal 18 mm diameter and 1.2 mm wall thickness provide a balance of flow capacity and structural rigidity for typical residential and light-commercial applications. Supplied in 3 m sections, the pipe is easy to transport, store and cut to length on site.

Suitable for

• Domestic and commercial hot and cold water supply lines
• Heating circuits and radiator connections
• Plumbing installations requiring a galvanized external surface
• General fluid distribution where mechanical durability is needed

Key specifications

• Material: carbon steel with external zinc galvanization
• Outer diameter: 18 mm (nominal)
• Wall thickness: 1.2 mm
• Length: 3 m per section
• Surface treatment: external zinc coating for corrosion protection

How to use

Measure and mark the required pipe length, then cut the 3 m section with an appropriate pipe cutter or saw suitable for carbon steel. Deburr the cut edges and protect threads or joints according to the chosen connection method. Install using compatible fittings and follow standard plumbing or HVAC installation practices, ensuring correct alignment, support spacing and sealing. Pressure-test the assembled system in accordance with applicable regulations before commissioning.

Usage recommendations

Use pipe supports at regular intervals to prevent sagging, avoid prolonged exposure of cut ends to corrosive environments and apply suitable joint sealing materials compatible with galvanized steel. For internal corrosion-sensitive systems, consider internal lining or compatible fitting materials when required by application specifications.
