Nickel Based Threadolet Inconel 625 Forging Standard MSS SP-97 No Welding for Low Pressure

Nickel Based Threadolet Inconel 625 No Welding For Low Pressure

ⅠThreadolet (Threaded Olet)
1.Connection Method: Branch end features a Threaded connection. The externally threaded branch pipe is directly screwed into the olet.
2.Branch Pipe Connection End: Internal Threads (NPT/BSPT). The externally threaded branch pipe is screwed in directly. No welding is required; sealing relies on thread engagement.
3.Welding Requirements: No welding is needed. It is a purely mechanical connection, with sealing dependent on thread contact.
4.Typical Appearance: The branch end is a threaded hole. The end of the branch pipe has external threads, and thread patterns are visible at the connection point.
5.Pressure Rating: Lower ratings (typically ≤ Class 6000#), suitable for medium-to-low pressure and ambient temperature applications (e.g., instruments, small valves).
6.Installation Complexity: Enables quick threaded assembly with no hot work required. Ideal for scenarios involving frequent disassembly or maintenance.
7.Leakage Risk: Threads may loosen due to vibration or temperature fluctuations, requiring regular maintenance to prevent leaks.
8.Typical Applications: Low-pressure branch pipes, instruments/valves requiring frequent disassembly (e.g., pressure gauges, sampling valves).
9.Standard Interface: Threads conform to NPT/BSPT standards.

Ⅱ Similar Features of Sockolets and Threadolets
1.Functional Role
Both are categorized as Olet Fittings, engineered to form branch connections in main pipelines. They act as substitutes for traditional reducing tees, with particular suitability for high-pressure, high-temperature, or large-diameter piping systems (such as petrochemical plants and nuclear power facilities).
2.Structural Design
▶ Reinforced Build: Both are forged parts made from the same material as the main pipe, featuring self-reinforcing structures that help reduce stress concentration.
▶ Attachment Way: Both are permanently fixed to the main pipe through butt welding (connecting the base to the pipe), with branch connections positioned at a 90-degree angle.
3.Compliance with Standards
Both follow MSS SP-97 (Forged Socket Weld and Threaded Branch Connections), which defines requirements for design, dimensions, and pressure ratings.
4.Application Fields
They work well in space-limited environments where easy installation is needed, such as instrument connections and small-diameter branch pipes.

Ⅲ Material Traits: The Advantages of Inconel 625 Nickel Alloy
UNS N06625 (Inconel 625) delivers superior performance due to its carefully calibrated elemental makeup:
1.Key Elements: Ni ≥58% (forms a stable base structure), Cr 20–23% (resists oxidation and corrosion), Mo 8–10% (withstands acids and alkalis), Nb+Ta 3.5–4.5% (refines grain structure and stops cracking), Fe ≤5%.
2.Core Performance Features:
▶ Corrosion Resistance: Strong resistance to pitting and crevice corrosion in environments like seawater, hydrochloric acid, and high-temperature flue gases.
▶ High-Temperature Performance: Remains structurally sound up to 980°C (with short-term tolerance over 1000°C), and has better oxidation resistance than ordinary stainless steels.
▶ Mechanical Properties: Tensile strength of at least 827 MPa (120 KSI) at room temperature, keeps high toughness in extremely low temperatures, and has a low work-hardening rate, making it easy to fabricate.
