The BelGAS division of Marsh Bellofram Corporation introduced the Type 52SS, a family of NACE-compliant, stainless steel gas pressure regulators and filters. The Type 52SS is designed for a variety of sour gas, high-corrosion and other severe environments. The regulators are offered with a wide range of available port sizes, from ¼-inch up to an industry exclusive 1-inch NPT.
The BelGAS Type 52SS features a 316 stainless steel housing and filter assemblies, with fluorocarbon elastomers used for the control diaphragm and supply valve. The Type 52SS operates over pressure ranges of up to 150 PSIG (10.3 BAR), with excellent stability, repeatability and low droop, according to the company. Type P52SSFR and P52SSAR regulators, as well as Types P52SSF and P52SSAF, have built-in dripwells for trapping water, oil and other contaminants. Contaminants are flushed from the dripwell via a manual or automatic drain valve. A removable 40-48 micron filter is constructed of sintered 316 stainless steel. The units also feature a tapped vent for ease of exhaust gas capture.
BelGAS Type P52SS gas pressure regulators can be mounted in one of three configurations: through-panel mounted, with the supplied mounting nut (regulators only); bracket-mounted, using the optional bracket (regulators only), or pipe mounted, via its ports (regulators and filters). The regulators and filter assemblies comply with NACE Standard MR0175 (Metals for Sulfide Stress Cracking and Stress Corrosion Cracking Resistance in Sour Oilfield Environments). Filter-only assemblies are also available upon request.
Typical applications for the Type 52SS include petrochemical processing, chemical plants, food processing and paper/pulp mills.
