For metallurgical DRI equipment operating under high-temperature, continuous, and heavy-duty conditions, we use our self-produced Zest CA2269 welding wire to stably replace the imported Trtien T23 welding wire.
We specialize in manufacturing finished conveying pipelines and four-way pipe fittings.
With the strength of our self-developed welding consumables, we ensure the safe and reliable operation of key pipelines.

Zest CA2269 welding wire is deeply optimized for the welding of heat-resistant alloy steels. It features matched chemical composition, qualified mechanical properties and stable process performance, and can fully meet the welding requirements of T23 welding wire in high-temperature pressure-bearing pipelines.
The weld metal exhibits uniform microstructure, excellent creep resistance and oxidation resistance, with minimal deformation and cracking during long-term service. It satisfies the stringent standards for continuous production in DRI equipment.
From straight pipe sections to four-way distribution nodes, we apply standardized welding procedures and quality control throughout the process:
-
Precise temperature control during pre-welding preparation to reduce welding stress.
-
All-position welding with smooth formation, consistent penetration, and freedom from porosity and slag inclusions.
-
Post-weld inspection covering dimensional, mechanical, and non-destructive testing, in full compliance with metallurgical equipment delivery standards.
