H1400-30 - Smith Equipment H1400-30 Fixed Flow Orifice Adaptor, 30 SCFH

Precise Gas Flow Control with Smith Equipment H1400-30

The Smith Equipment H1400-30 Fixed Flow Adaptor is a specialized gas regulation component designed to deliver a constant flow rate of 30 Standard Cubic Feet Per Hour (SCFH). Engineered for industrial reliability, this adaptor is an essential tool for facilities requiring strict adherence to welding procedure specifications (WPS) or other processes where gas flow consistency is critical. By utilizing a fixed orifice system, the H1400-30 eliminates the variability associated with adjustable flowmeters, ensuring that the downstream process receives exactly the amount of gas required—no more, no less.

This unit is calibrated to operate at an inlet pressure of 30 PSIG. It is commonly installed on pipeline drops or directly into the outlet of a standard pressure regulator. The inlet connection features a 5/8"-18 UNF Female thread, compatible with standard CGA fittings often found on regulator outlets and gas hoses. The outlet is machined with a 1/4" NPT Male thread, allowing for seamless integration into hard-piped systems, manifolds, or custom hose assemblies. A key feature of the H1400-30 is its integrated inlet filter. This sintered element traps particulate matter and debris before it reaches the precision-drilled 0.032-inch orifice, preventing clogs and maintaining flow accuracy over the lifespan of the device.

For facility managers and procurement specialists, the H1400-30 represents a cost-effective method for controlling consumable costs. In large-scale welding operations, "gas surge" and operator tampering (increasing flow unnecessarily) can lead to significant waste. This fixed-flow solution mitigates those risks by physically limiting the maximum flow to the optimal 30 SCFH, provided the inlet pressure is maintained at the specified 30 PSIG. The robust brass construction ensures compatibility with a wide range of inert and non-corrosive gases used in welding and industrial applications.
