HELIUM, HYDROGEN, METHANE MANIFOLDS W/O FLASHBACK ARRESTER

Rexarc manifold systems let you concentrate your cylinders in one location so they’re not scattered throughout work areas. This reduces cylinder handling costs by giving you greater control over your fuel gas supply. Since your cylinders are located in a central area, you always know where they are. Plant safety is improved, record keeping is kept to a minimum and labor costs are cut because only a few minutes of one person’s time is necessary to service the manifold. In addition, you increase production by eliminating interruptions at user stations to change cylinders and save gas as well, since all cylinders will be emptied uniformly.

 

Rexarc hydraulic flashback arresters are not required when hydrogen, methane is used without oxygen or compressed air. Convoluted stainless steel cylinder pigtails are used due to the specific gravity of the gases. Rexarc helium, hydrogen, methane distribution systems comply to National Fire Protection Association Bulletin #51.

 

Selecting the correct size helium, hydrogen, methane manifold.

 

To select the proper manifold for your operation, consider these points:

  • Calculate the flow (scfh) at each outlet in the piping system.Add the cubic feet per hour flow rate of each.The total will give you the volume of helium, hydrogen, methane needed per hour.
  • The manifold should have enough cylinders to provide for at least one day’s gas requirements.
