DN10~DN600 2000~15000 Psi Titanium & Titanium Alloys Pressure Testing Bl Flange
DN10~DN600 2000~15000 Psi Titanium & Titanium Alloys Pressure Testing Blind Flange | SSM
SSM manufactures and supplies titanium and titanium alloy blind flanges for pressure testing systems ranging from 2000 to 15000 psi, available in sizes DN10 to DN600. These flanges are designed according to ASME, ANSI, and EN standards, offering exceptional corrosion resistance, lightweight performance, and superior mechanical strength under extreme pressure conditions.
1. Product Overview
The Titanium Blind Flange (BL) is used to seal or terminate pipelines and pressure test systems. It allows isolation of flow and is frequently used in chemical processing, marine systems, and aerospace pressure equipment where high purity and corrosion protection are essential.
Type: Blind Flange (BL)
Material: Titanium & Titanium Alloys (e.g., Gr.2, Gr.5, Gr.7)
Size Range: DN10 – DN600
Pressure Rating: 2000 – 15000 PSI
Standard: ASME B16.5 / EN 1092-1 / MSS SP-44
2. Material Grades and Chemical Composition
| Grade | Composition Highlights | Key Features |
|---|---|---|
| Grade 2 (UNS R50400) | Commercially pure titanium (99.2%) | Excellent corrosion resistance, moderate strength |
| Grade 5 (Ti-6Al-4V) | 6% Al, 4% V | High strength-to-weight ratio, excellent fatigue resistance |
| Grade 7 (Ti-0.2Pd) | Palladium alloyed | Superior resistance to crevice and reducing acid corrosion |
Titanium alloys combine low density (≈4.5 g/cm³) with high tensile strength (up to 1000 MPa), making them ideal for lightweight, high-pressure applications.
