Why SA-403 WP316/316L Pipe Fittings?
SA-403 WP316/316L fittings are widely selected for chemical processing plants, offshore facilities, marine engineering, water treatment systems, and other corrosive environments. Their low-carbon composition minimizes the risk of intergranular corrosion after welding, while molybdenum enhances resistance to chlorides and aggressive chemicals.
For this Indonesian project, the selected material provides:
- Excellent corrosion resistance in humid and chloride-containing environments.
- Superior weldability for field installation.
- Reliable mechanical strength under demanding operating conditions.
- Long service life with reduced maintenance costs.
Throughout this project, SA-403 WP316/316L fittings were manufactured with careful control of dimensions and surface quality to ensure smooth installation and dependable sealing performance.
Strict Manufacturing and Quality Control
Quality assurance is a key part of every Haihao Group project. Before shipment, each fitting completed a complete manufacturing and inspection process.
| Inspection Item | Requirement |
| Manufacturing Standard | ASME B16.9 |
| Material Grade | SA-403 WP316/316L Stainless Steel |
| Heat Treatment | Solution Heat Treatment Completed |
| Mechanical Properties | Verified to Project Requirements |
| Dimensional Inspection | 100% Checked Before Packing |
| Surface Finish | Clean, Smooth and Free from Visible Defects |
