Large Diameter Stainless Steel 316 Tube Sheet Flange
Large Diameter Stainless Steel 316 Tube Sheet Flange
SSM manufactures and supplies large-diameter tube sheet flanges made from stainless steel 316, designed for heat exchangers, pressure vessels, condensers, and evaporators. These flanges offer excellent corrosion resistance, strength, and precision machining quality, making them ideal for industrial applications under demanding environments.
🔹 Product Overview
The tube sheet flange serves as the connecting base between tubes and shells in heat exchange equipment. Made of 316 stainless steel, it resists pitting, crevice corrosion, and chloride-induced stress cracking. Its large-diameter design provides stability and sealing performance for high-temperature and high-pressure systems.
🔹 Chemical Composition (Typical, %)
| Element | C | Mn | Si | P | S | Cr | Ni | Mo |
|---|---|---|---|---|---|---|---|---|
| 316 | ≤0.08 | ≤2.00 | ≤1.00 | ≤0.045 | ≤0.03 | 16.0–18.0 | 10.0–14.0 | 2.0–3.0 |
The addition of molybdenum (2–3%) improves resistance to corrosion in acidic and saline environments, particularly in marine and chemical industries.
🔹 Mechanical Properties
| Property | Value |
|---|---|
| Tensile Strength (MPa) | ≥515 |
| Yield Strength (MPa) | ≥205 |
| Elongation (%) | ≥40 |
| Hardness (HB) | ≤217 |
These mechanical characteristics ensure excellent load-bearing capacity and long service life even under continuous high-temperature operation.
