UNS N06625 Sockolet Forging Olet Fittings For High Pressure

UNS N06625 Sockolet Forging Olet Fittings For High Pressure

ⅠSockolet (Socket Weld Olet)
1.Connection Method: Branch end features Socket Weld connection. The branch pipe is inserted into the socket and welded.
2.Branch Pipe Connection End: Socket Design. The branch pipe is inserted and fillet welded. No threads. The pipe end is flat.
3.Welding Requirements: Requires both socket welding and fillet welding. Welds must undergo NDT.
4.Typical Appearance: Branch end forms a cup-shaped socket. Insertion depth of the branch pipe is approximately 3-5mm. Weld is a circumferential fillet weld.
5.Pressure Rating: Higher ratings available (up to Class 9000). Suitable for high-pressure, high-temperature applications (e.g., power plants, refineries).
6.Installati on Complexity: Requires welding expertise. Skilled welders are essential. Longer installation time due to welding and inspection.
7.Leakage Risk: Welded seal provides superior reliability. High long-term stability under pressure cycling.
8.Typical Applications: High-pressure pipeline branches (e.g., main steam line to instrument connections). Ideal for permanent, non-removable systems.
9.Standard Interface: Socket bore is precisely matched to the outer diameter of the branch pipe.

ⅡCommonalities Between Socket Weld Olet and Threaded Olet
1.Functional Purpose
Both are classified as Olet Fittings, designed to create branch connections on main pipelines. They serve as alternatives to traditional reducing tees, specifically suited for high-pressure, high-temperature, or large-diameter pipeline systems (e.g., petrochemical, nuclear power industries).
2.Structural Design:
▶Reinforced Construction: Both are forged components made from the same material as the main pipe, providing self-reinforcing structures to minimize stress concentration.
▶Welding Method: Both are permanently attached to the main pipe via butt welding (base-to-pipe connection), with branch connections oriented at a 90° angle.
3.Standards Compliance
Both adhere to MSS SP-97 (Forged Socket Weld and Threaded Branch Connections), which specifies design, dimensions, and pressure ratings.
4.Application Scenarios
Ideal for space-constrained environments requiring simplified installation, such as instrument connections and small-bore branch pipes.

ⅢMaterial Properties: The "Superpowers" of Inconel 625 Nickel-Based Alloy
UNS N06625 (Inconel 625) achieves exceptional performance through precise elemental composition:
1.Key Elements: Ni ≥58% (forms stable matrix), Cr 20–23% (oxidation/corrosion resistance), Mo 8–10% (acid/alkali resistance), Nb+Ta 3.5–4.5% (grain refinement, crack inhibition), Fe ≤5%
2.Core Performance Metrics:
▶Corrosion Resistance: Exceptional resistance to pitting and crevice corrosion in seawater, hydrochloric acid, and high-temperature flue gas environments.
▶High-Temperature Stability: Maintains structural integrity up to 980°C (short-term tolerance up to 1000°C), outperforming conventional stainless steels in oxidation resistance.
▶Mechanical Properties: Tensile strength ≥827 MPa (120 KSI) at room temperature, retains high toughness at cryogenic temperatures, low work-hardening rate for ease of fabrication
