In industrial piping projects, standard products are not always enough. Different projects may require specific dimensions, materials, pressure ratings, connection types and quantities.
Recently, HD-STEEL Group completed a supply project involving stainless steel flanges and pipe fittings in SS316L, PN16, covering multiple flange types and large-diameter sizes up to DN800.
This project demonstrates our ability to supply large diameter stainless steel flanges and project-specific pipe fittings for industrial piping applications.
| Product | Size Range | Material | Pressure Rating |
| Blind Flange | DN150–DN500 | SS316L | PN16 |
| Slip-On Flange | DN80–DN800 | SS316L | PN16 |
| Socket Weld Flange | DN40 | SS316L | PN16 |
| 45° LR Elbow | DN150–DN300 | SS316L | PN16 |
| 90° LR Elbow | DN80–DN500 | SS316L | PN16 |
The largest item in this project was the DN800 Slip-On Flange, demonstrating our capability in manufacturing and supplying large-diameter stainless steel flange products.
Large-diameter flanges require careful control of dimensions, bolt-hole positioning, facing, thickness and overall geometry.
For project-specific orders, HD-STEEL Group can manufacture and supply stainless steel flanges according to the customer's required:
