32144 - Replacement Inner Flow Tube for CO2 Flowmeters

Precision Replacement for Industrial Gas Regulation

The ESAB 32144 Inner Flowmeter Tube is a critical replacement component designed to restore the operational accuracy of industrial gas flowmeters. In the realm of welding and fabrication, the precise delivery of shielding gas is paramount to maintaining structural integrity and meeting code requirements. This specific tube is engineered and calibrated exclusively for Carbon Dioxide (CO2), taking into account the specific density and flow characteristics of the gas to provide accurate volumetric readings. Unlike generic tubes that may offer dual scales or approximate readings, this OEM-quality component ensures that the flow rate displayed corresponds exactly to the gas being dispensed.

Constructed from high-durability materials, typically impact-resistant polycarbonate or similar engineering plastics, the tube is designed to withstand the rigors of the shop floor environment. It serves as the central metering element within the flowmeter assembly, housing the float ball that rises in proportion to the gas flow. Over time, flow tubes can become clouded due to contaminants in the gas supply, or cracked from accidental impact or overtightening during maintenance. A compromised tube not only makes readings difficult but can also lead to gas leaks, posing safety hazards and wasting expensive consumables. Replacing the inner tube with the ESAB 32144 is a cost-effective maintenance strategy that extends the service life of the regulator assembly.

Installation of the 32144 requires disassembly of the flowmeter housing. It is essential that maintenance personnel verify compatibility with the specific regulator model in use, as tube dimensions and seating surfaces vary by manufacturer and series. Once installed, the clear, high-contrast markings allow operators to verify flow rates at a glance, ensuring that the welding process remains within the specified procedure parameters. This component is an indispensable spare part for maintenance departments responsible for the upkeep of welding stations and gas distribution manifolds.
