Problems encountered by customers
- A customer of a Saudi Arabian hardware manufacturing company pointed out that hand polishing cannot remove heat-induced discoloration and oxide scale from welded stainless steel pipes and flanges, which poses a risk of corrosion in harsh environments.
- Inconsistent surface finish can lead to fluid friction and localized pitting corrosion, thus shortening the lifespan of desalination equipment.
- High labor costs and low efficiency: each large pipe fitting requires 120 minutes, and rework rates are as high as 30% due to uneven metal removal.
Weshining’s solution
- A clean and uniform surface finish was achieved, with a surface roughness Ra ≤ 0.02μm, free from any oxide residue or thermal damage.
- Polishing time for each part was reduced from 120 minutes to 15 minutes, an 87.5% increase in speed.
- Zero rework was achieved, with 100% consistent polishing results across all batches, resulting in a 55% reduction in annual polishing costs.
