Product Specification

Forged Pipe Fittings CuNi Sockolet ASTM B466 UNS C71500 1" 3000LB ASME B16.11

1. Product Description

This product is a forged CuNi Sockolet manufactured from UNS C71500 (70/30 Copper-Nickel alloy / CuNi 70/30) in accordance with ASTM B466 and ASME B16.11 standards. A Sockolet is a specialized branch connection fitting used to connect a smaller branch pipe to a larger main pipe (run pipe). Unlike standard tees, an Olet family fitting is shaped to match the curvature of the run pipe and contains internal reinforcement, making it stronger and better suited for high-stress applications. UNS C71500 offers higher strength compared to C70600 due to its 30% nickel content. This 1" Class 3000# fitting features a socket weld (SW) connection on both the branch and main pipe sides.

2. Key Product Parameters

3. Application / Usage

This Sockolet is ideal for seawater and corrosive fluid systems requiring branch connections:

• Marine & Shipbuilding: Seawater piping systems, offshore platforms, shipboard piping

• Oil & Gas: High-pressure process lines, subsea applications, chemical injection lines

• Power Generation: Condenser and heat exchanger piping

• Chemical Processing: Corrosive fluid handling, pharmaceutical equipment

• Instrumentation Taps: Space-limited piping systems

4. Advantages

• Superior Corrosion Resistance: Exceptional resistance to seawater corrosion, pitting, and chloride stress corrosion cracking

• Biofouling Resistance: Naturally resists marine biological growth

• Enhanced Strength: 30% nickel content provides higher strength than 90/10 CuNi

• Socket Weld Reliability: Provides leak-proof, permanent connection with high resistance to loosening

• Internal Reinforcement: Sockolet design is stronger than standard tee connections for high-stress applications

• Cost-Effective: Threadless welding reduces installation time and labor costs compared to flanged connections

5. Functions

The Sockolet creates a reinforced branch connection from a larger main pipe to a smaller branch pipe (1"). It is welded directly onto the run pipe after cutting a hole, providing a strong, leak-tight junction for fluid diversion. The socket weld connection involves inserting the pipe into the socket and applying a fillet weld around the joint, forming a permanent, pressure-rated connection suitable for high-temperature and high-pressure environments.

6. Installation Instructions

1. Preparation: Clean the run pipe surface and Sockolet socket interior thoroughly; remove all dirt, oil, and debris.

2. Marking: Mark the exact drilling location on the run pipe per specification.

3. Drilling: Drill the run pipe at the marked location to the required diameter.

4. Fitting Placement: Position the Sockolet over the drilled hole, ensuring proper alignment with the run pipe curvature.

5. Welding: Insert the branch pipe into the Sockolet socket leaving a 1/16" (1.6 mm) expansion gap. Perform fillet welding around both the Sockolet-to-run pipe and branch pipe-to-Sockolet joints using approved WPS with certified welders.

6. Cleaning: Post-weld cleaning and inspection as per quality procedure; no post-weld heat treatment required.

7. Precautions

• Socket Gap: The 1/16" expansion gap is mandatory to prevent thermal expansion cracking during service.

• Cleanliness: Requires a higher degree of cleanliness than steel fabrication to prevent contamination.

• Temperature Limit: Maximum service temperature ~400°C; avoid operation above this range.

• Welding Procedure: Use inert gas shielding (argon) for welding to prevent oxidation.

• Filler Metal: Use matching 70/30 CuNi filler metal (e.g., ERCuNi) for welding.

• Inspection: Visual and PT examination recommended for fillet weld integrity after installation.

8. Shipping & Delivery

• Standard delivery time is typically 15–30 days, subject to order quantity and specification availability.

9. Payment Terms

• Common international payment methods include T/T (Telegraphic Transfer) and L/C at sight (Letter of Credit).

10. Packaging

• Products are securely packed in plywood cases or wooden crates with internal cushioning to ensure safe transportation and prevent damage during transit.

11. After-Sales / Return & Warranty Policy

• All products undergo strict quality inspection before shipment, with Mill Test Certificates (EN 10204 3.1/3.2) available.

• In case of quality issues, retain original packaging and provide relevant photos or third-party inspection reports.

• Specific return, exchange, and warranty terms are subject to the final sales contract agreement.
