Product Description
Imagine a pipe-fitting solution that doesn’t just connect your high-pressure system — but reinforces it. Our High Pressure 3000 Lb Duplex Stainless Steel Pipe Fittings are engineered for mission-critical pipelines where failure is not an option.
Each fitting is forged from duplex stainless steel, a robust two-phase alloy combining austenitic and ferritic microstructures. This gives it a compelling tactile confidence: the smooth, cool finish of stainless steel, but with a solid, weighty heft that conveys strength at a glance.
These fittings whisper assurance under pressure. Whether welded or threaded, they deliver leak-proof reliability even in systems pushing 3000 psi. The surface has a clean, metallic sheen—no rough edges, no weak points. When installed, you’ll feel the quiet solidity, but you won’t hear any compromising hiss or vibration.
Exceptional Strength and Durability
Duplex stainless steel dramatically outperforms standard austenitic steels in yield strength—crucial in high-pressure service.
Superior Corrosion Resistance
Outstanding resistance to chloride stress corrosion cracking and pitting means longer life in aggressive environments.
Versatile Connection Options
Supports socket weld, threaded (NPT), and butt-weld connections to fit your system’s design.
Comprehensive Range of Fitting Types
Available in elbows (45° or 90°), tees, crosses, couplings, unions, reducers, and caps—adaptable for any configuration.
High-Pressure Certified
Rated to Class 3000 / 3000 lb, tested to rigorous standards to guarantee performance under extreme pressure. This aligns with industry‑accepted standards used by peer manufacturers.
Stringent Quality Control
Supplied with mill test reports, material traceability, and optional independent third-party certification (e.g., EN 10204 / 3.1B).

The heart of these fittings is Duplex Stainless Steel, typically grades like ASTM A182 F51 / UNS S31803 / S32205. This alloy’s unique microstructure (ferrite + austenite) brings together:
High mechanical strength – up to ~480 MPa yield strength in some duplex grades.
Improved fatigue resistance – the two-phase nature helps resist cracking under cyclic loads.
Excellent corrosion behavior – especially in chloride-rich or chemically aggressive environments common in oil, gas, and marine systems.
In your hands, the fitting feels dense and balanced. Its dual-phase structure is invisible to the eye, but its benefits are evident in performance.
Ideal for environments that demand both pressure resilience and corrosion resistance:
Oil & Gas Industry: High-pressure transport lines, wellheads, subsea assemblies.

Q1: What does “3000 Lb / Class 3000” mean?
A: The fittings are rated for approximately 3000 psi, qualifying as high-pressure service.
Q2: Why use duplex stainless steel instead of standard stainless (304/316)?
A: Duplex steel offers higher yield strength, better resistance to stress corrosion cracking, and improved durability under high-pressure conditions.
Q3: Which standards are these fittings manufactured to?
A: Forged per ASME B16.11; threaded parts per ASME B1.20.1 (NPT).
Q4: Do you provide material test certificates or third-party inspection?
A: Yes. Mill test reports are standard; third-party inspection can be arranged.
Q5: Can you supply custom sizes or non-standard fittings?
A: Yes, custom manufacturing is available for special alloys, dimensions, or pressure classes.
Q6: How do these fittings help my total cost of ownership?
A: High strength and corrosion resistance reduce replacement frequency, maintenance, and total system cost.
