Fire Sprinkler Pipe and Fittings - Things You Must Know
In fire sprinkler pipe system, the hot-dip galvanized pipe could be used, either manufactured in ERW or Seamless type. The galvanized fire sprinkler pipe with an inner and outer wall diameter of less than 100 mm, thread connection can be used. Likewise, if the galvanized fire pipe in ERW, malleable iron threaded pipe fittings are fitted.

The basic specification for hot dip galvanized coatings on iron and steel articles is defined by a single standard, EN ISO 1461 ‘Hot dip galvanized coatings on iron and steel articles – specifications and test methods’. However, there are some exceptions to this standard (see thicker coatings below).
Hot-dip galvanised. We offer an extensive range of products in hot-dip galvanised steel finishing that are especially designed for outdoor application. In contrast to standard galvanised or surface-galvanised finishes, hot-dip galvanising provides a higher layer thickness and a sealed coating which guarantees better corrosion protection.
