1305 Series Regulators Introduction The 1305 Series regulators (Figure 1) are directoperated, pressure-reducing regulators that resist hydrate formation and regulator freeze-up. The regulators are suitable for service with natural gas, air, propane, and other gases compatible with the internal parts. 1305 Series regulators are typically used on high-pressure lines from wellheads and separators. Regulator freeze-up resistance (see Figure 2) occurs as the pipeline gas warms the finned inlet adaptor and the orifice area. As the gas cools within the inlet adaptor due to pressure drop and volume expansion, the warm inlet adaptor helps keep the gas temperature above the freezing point of water and the hydrate formation temperature.

These constructions comply with the recommendations of NACE International Standards MR0175 and MR0103. Overpressure Protection Like most regulators, the 1305 Series have outlet pressure ratings lower than their inlet pressure ratings. finned inlet adapter heated by main flow stream to help prevent regulator freeze-up w060-1* INLET PRESSURE OUTLET PRESSURE ATMOSPHERIC PRESSURE Figure 2. Type 1305C Operational Schematic Complete downstream overpressure protection is needed if the actual inlet pressure exceeds the outlet pressure rating. Overpressuring any portion of a regulator or associated equipment may cause leakage, part damage, or personal injury due to bursting of pressure-containing parts or explosion of accumulated gas. Regulator operation within ratings does not preclude the possibility of damage from external sources or from debris in the pipeline. A regulator should be inspected for damage periodicall
