Hammer Union FIG 206 Overview

Hammer Union FIG 206 is a quick make-up union used to connect compatible piping or fluid-handling equipment where regular assembly and disassembly may be required. The existing product information identifies a forged-steel construction, butt-weld ends and a published working pressure up to 2,000 psi (2M). The exact manufacturer, size, configuration and rating must be confirmed before selection.

FIG 206 Identification and Pressure Rating

Figure number is not a complete specification

The FIG 206 designation helps identify a hammer union family, but it does not by itself confirm interchangeability, material grade, seal arrangement or suitability. Buyers should match the complete figure, size, manufacturer or compatible series, end connection and pressure class.

Forged-Steel Body and Butt-Weld Ends

The current listing describes forged-steel components with butt-weld ends. Confirm the material grade, dimensions, weld-end preparation, schedule or bore, heat treatment and any material certificate for the selected size. Welding must follow an approved procedure suitable for the component and connected pipe.

Union Components and Sealing Interface

Confirm nut, subs and seal details

A hammer union typically relies on matched sub components, a wing nut and the specified sealing interface. Components from different figures, sizes or manufacturers should not be mixed unless compatibility is formally documented. Inspect threads, shoulders and sealing surfaces before every make-up.

Media and Application Review

Air, water, oil and selected fluid-transfer duties are mentioned in the existing information, with oilfield, gas and industrial contexts. These examples are not automatic approval. Fluid composition, solids, corrosion, temperature, pressure cycling, pulsation, vibration and applicable site requirements must be assessed.

Information Required for FIG 206 Selection

Provide complete connection and duty data

• Required figure number, nominal size and quantity
• Manufacturer or existing mating-union identification
• Butt-weld dimensions, pipe schedule or bore and material
• Fluid, solids content and normal or maximum temperature
• Normal, maximum and surge pressure
• Required seal arrangement and material documentation
• Testing, inspection, certification and colour-identification needs

The published 2,000 psi value must be checked against the exact union size, manufacturer data, temperature and complete line design.

Installation and Safety Guidance

Only trained personnel should weld, assemble and inspect hammer unions. Isolate and fully depressurise the line before make-up or break-out. Do not strike or tighten a union under pressure. Use appropriate tools and site procedures, avoid damaged components, and complete the required inspection and pressure test before service.

Frequently Asked Questions

Are all FIG 206 hammer unions interchangeable?
No. Dimensions and sealing details can differ. Confirm the manufacturer or documented compatibility with the mating half.

Is every FIG 206 union rated to 2,000 psi?
Do not assume so. Verify the exact size, manufacturer data, temperature, condition and system design.

What should I send for a quotation?
Send the figure, size, mating-union details, weld-end dimensions, fluid, pressure, temperature, quantity and certificate requirements.
