Robust safety screens resist corrosion and combustion

23 September 2015

The wide range of HI-BAR flange mount safety screens from Lee Products now includes options made entirely from brass and compliant with ASTM B16/B16M.

Lee HI-BAR screens protect components in critical fluids handling applications to ensure optimum safety and performance. While critical components are often relatively immune to low levels of small size contaminants, a single large particle can cause blockages, resulting in system failure and down-time.

These rugged, all-brass versions combine high strength and a one-piece design suitable for applications and environments which have a risk of ignition, combustion and corrosion.  In addition, as brass is less likely to ignite or burn (compared to aluminium or stainless steel) it is also considered as a superior material for use in oxygen applications. Brass's low propensity for sparking also ensures suitability for use in explosive gas environments.

Depending on size, their robust, single piece construction enables these screens to withstand fully clogged pressure differentials of 1,000psid to 4,500psid, without rupture. They are available in six different flange sizes, ranging from 3.35mm to 17.1mm in diameter and eight different hole sizes ranging from 0.05mm to 0.5mm in diameter.

Although the 48 ‘standard’ versions offer optimum design flexibility, custom designs are also available.
