Product Overview: Robust Connection for Small-Bore, High-Pressure Systems
Our Forged Steel Socket Weld Flange is specifically engineered for small-bore (½″–4″), high-pressure (Class 150–Class 2500) critical piping systems. Manufactured in strict compliance with ANSI/ASME B16.5 standards, it delivers superior strength and guaranteed leak-proof performance.
The Socket Weld design is the core advantage: it allows the pipe to be precisely inserted into the recessed area of the flange. The subsequent external fillet weld creates a connection with high structural integrity, effectively reducing fluid turbulence and guaranteeing sealing integrity even under extreme conditions (such as high-pressure steam or corrosive chemicals).
🛠️ Technical Specifications & High-Pressure Performance
| Feature | Detailed Specification | Value Proposition |
| Flange Type | Socket Weld Flange (SW) – Forged Steel Construction. | High Structural Strength: Ideal for high-pressure and thermal cycling where superior rigidity is required over slip-on types. |
| Standard Compliance | ASME B16.5. | US Standard Precision: Ensures dimensional compatibility and full interchangeability with international standard piping components. |
| Size Limitation | **Small Bore (½″–4″) ** (DN15–DN100). | Targeted Application: Designed specifically for high-pressure branch lines, instrumentation, and valve connections. |
| Pressure Rating | Class 150 up to Class 2500. | Maximum Pressure Capability: Capable of handling the most rigorous high-pressure and hazardous media transport requirements on the market. |
| Material Options | Carbon Steel (A105); Stainless Steel (304/316 L); Alloy Steel available. | Environmental Adaptability: 316L Stainless Steel offers excellent corrosion resistance for chemical and petrochemical services. |
| Sealing Face | Raised Face (RF), Ring Type Joint (RTJ). | Reliable Sealing: The RTJ face is the preferred choice for ensuring a zero-leakage connection in Class 600 and higher high-pressure systems. |
🌍 Key Applications & Industry Service
