Horizontal offset piping used for expansion should be installed at a minimum of how many metres?

  1. 1 metre

  2. 1.5 metres

  3. 2 metres

  4. 2.5 metres

The correct answer is: 1.5 metres

Horizontal offset piping is used for expansion, meaning that it allows for movement due to temperature changes. The minimum distance at which it should be installed is 1.5 metres. This allows for enough flexibility and movement without causing any damage or strain to the piping. Choosing options A or C would not provide enough room for expansion and could potentially cause damage to the piping. Option D, while providing more room, may be excessive and unnecessary in most situations. Therefore, option B is the most suitable choice.
