Listening to Customer Voices, Driving Product Iteration
Over the years, Saemin's technical team has continuously collected hundreds of customer feedback reports from the pipeline engineering field. Addressing key customer pain points such as "cumbersome operation," "complex parameter adjustments," and "insufficient equipment adaptability," our design department has made improvements to the DN400mm in several aspects
Optimized Manual Operation
Simplified clamping processes reduce physical strain, while retaining the fine-tuning freedom that experienced welders require.
Launch of Fully Automatic Model
Catering to the demand for smart manufacturing, this model utilizes pre-set welding programs and adaptive algorithms to enable fully automatic, multi-angle welding of pipes with varying diameters, significantly boosting efficiency and consistency.
Empowering with Technology, Delivering Real Value
The upgraded DN400 series not only covers a pipe diameter range of 90mm to 400mm but also achieves flexible multi-angle welding (0-90°). Whether in semi-automatic mode with manual intervention or in fully automatic, unattended operation, the equipment maintains stable, high-quality output. One client noted, "The new model allows even our novice welders to get up to speed quickly, producing beautiful welds and reducing our defect rate by 30%.
