Product introduction
Huayang's Bonus: Full-Process Support Amplifies ERW's Advantages
ERW's lead is also boosted by Huayang's full-chain service. Pre-sales, our technical team customizes ERW specifications (diameter, wall thickness) based on project needs-for a 2024 chemical plant, we adjusted HFW's welding frequency to 450kHz, adapting to cyclic pressure. In-sales, 5 ERW lines can be activated simultaneously: the Henan project completed 10,000 tons in 8 days by coordinating 3 lines. After-sales, we provide weld test reports and on-site installation guidance, solving customers' worries.
Our full-category capacity (ERW/SAW/EFW/SMLS) also helps: when a project needs mixed calibers, we supply ERW for small diameters and SAW for large ones, avoiding multi-supplier coordination. This "one-stop" service made ERW the main force in 60% of Huayang's 2024 projects.
