3 Inch Hammer Union FIG 100 (Welded SCH40 & Threaded, 1,000 PSI CWP)
In low-pressure fluid transfer and industrial manifold operations, reliable quick-disconnect fittings are vital. Shanghai PME Industrial manufactures the premium 3 inch hammer union (FIG 100) engineered for utility lines, water transfer, and low-pressure oilfield service. Rated at a Cold Working Pressure (CWP) of 1,000 PSI, our series is offered in two primary end connections: Welded SCH40 and Threaded.
Having successfully completed manufacturing, rigorous dimensional inspection, and seaworthy packaging, this current batch is fully prepared for dispatch to active European drilling and industrial sites. Whether your project requires permanent welded piping integrity or field-serviceable threaded connections, PME delivers interchangeable, high-durability hardware built to industry standards.
Designed for direct butt-welding onto Schedule 40 piping systems in permanent utility lines.
Equipped with precision pipe threads for rapid mechanical connection and disassembly in temporary setups.
Finished units packed securely with clear cast pressure ratings and part numbers, ready for European delivery.

Comparison & Application Analysis: Welded SCH40 vs. Threaded
Selecting the appropriate end connection for a FIG 100 assembly depends heavily on the installation permanency and operational requirements of the piping network:
1. 3 Inch Hammer Union – Welded SCH40
The welded variant features ends prepared for direct butt-welding or socket connection to Schedule 40 piping systems. This configuration provides a permanent, leak-proof structural tie-in ideal for fixed production manifolds, permanent plant utility lines, and heavy vibration environments where threaded joints might loosen over time.
2. 3 Inch Hammer Union – Threaded
The threaded version utilizes standard pipeline threads, enabling fast screw-on connection to existing threaded pipes without requiring on-site welding equipment. It is the preferred choice for temporary water transfer lines, mobile mud systems, and modular surface equipment that undergoes frequent assembly, disassembly, and relocation.
3. European Export Quality & Logistics Readiness
Both variants are forged and machined to ensure complete interchangeability with standard Weco components. Finished with robust protective coatings and packed securely for international transit, this recent batch is fully staged to support European drilling contractors and equipment yards with zero-defect reliability.
