Acetylene safety equipment

A full range of acetylene safety equipment

Rotarex has developed a range of safety equipment for use in C2H2 production and filling plants. It includes flame arrestors for both high-pressure and low-pressure acetylene pipes, which prevent a flame from spreading in either direction.

Acetylene has a highly flammable nature that can cause burns or explosions if misused, so it's important to use safety devices. Today, acetylene is widely used for numerous applications, such as:

  • Oxyacetylene welding and metal cutting
  • Chemical Synthesis
  • Construction and Metalwork


  • Pressure control to prevent accidents
  • Flow control to ensure the correct flow
  • Leak prevention
  • Flame arresting to protect user and the equipment


  • Quick-acting shut-off device
  • Thermal shut-off device
  • Non-return valve
  • Flame arrester


  • Approved by validation test according to EN ISO 15615
  • In compliance with the PED 2014/68/EU directive
  • C2 H2 supply equipment as defined in ISO 14114
