Key Benefits and Advantages
-
Resists Hydrate Formation and Freeze-up: The 1305 Series is famous for its “anti-freeze” capabilities. When high-pressure gas expands rapidly, it cools significantly, which can lead to ice or hydrate blockages. The internal geometry and materials of the 1305 are designed to minimize these effects, keeping your gas lines flowing even in cold weather or high-pressure drop scenarios.
-
High Pressure Capabilities: These regulators are built to handle the extreme pressures found at the wellhead. With a maximum inlet pressure rating of up to 4000 psig (276 bar), they provide a safe and reliable first stage of reduction for raw natural gas and other high-pressure fluids.
-
Durable and Rugged Construction: To survive the abrasive and corrosive nature of wellhead service, the 1305 is constructed from high-strength materials. The design is focused on longevity, ensuring that the regulator can withstand the vibration and mechanical stresses common in oilfield equipment.
-
NACE Construction Available: For applications involving sour gas (H2S), the 1305 Series is available in materials that comply with NACE MR0175 standards. This provides essential protection against sulfide stress cracking, ensuring the safety of personnel and equipment.
-
Ease of Maintenance: The simple, direct-operated design allows for straightforward field service. The regulator can be inspected and the trim parts can be replaced without removing the body from the pipeline, which is a critical feature for remote wellsite locations.
-
Versatile Media Compatibility: While primarily used for natural gas, the 1305 is equally effective for air, propane, and other non-corrosive industrial gases.
