Is the SJ swivel coupling with GW BSP, brass suitable for chemical industry hoses up to 16 bar and -40Â°C to +250Â°C?

Yes . the SJ swivel coupling with GW BSP, brass is suitable for chemical industry hoses given the provided specifications. It is explicitly used in the chemical and petrochemical industry, rated for working pressure up to 16 bar and an operating temperature range of â40Â°C to +250Â°C. It is designed to prevent transfer of torsional moment and allows slow or oscillating rotations. Caveats: - The brass material may have chemical compatibility limits depending on the specific media (strong acids, ammonia, halogens, etc. can attack brass). Verify compatibility of brass with the specific chemicals handled. - The joint is not resistant to high bending moments; if significant bending or heavy-duty conditions are expected, use the double-bearing (heavy duty) swivel joint available on request. - Confirm thread/connection type (GW BSP) and any required approvals for your installation beyond PED/TDT/TÃV/Apragaz if applicable. If you provide the exact chemicals and hose type, I can confirm material compatibility and any additional recommendations.

Can the SJ swivel coupling with GW BSP, brass be fitted with NPT or ACME threads for different hose connections?

Yes. The SJ swivel coupling with GW BSP, brass can be supplied with NPT or ACME threads (and other thread/flange types) on request. The product description states various connections are available on request, including NPT and ACME, so different hose connection standards can be accommodated. Keep in mind material and operating limits: brass, -40Â°C to +250Â°C, up to 16 bar, slow/oscillating rotation. If high bending moments are expected, consider the double-bearing heavy-duty version.

Can the SJ swivel coupling with GW BSP, brass be supplied with double bearing for higher bending moment applications?

Yes. The SJ swivel coupling with GW BSP, brass can be supplied with a double bearing (heavy duty) for higher bending moment applications on request. The standard SJ swivel joint is fitted with a single bearing and is not resistant to high bending moments; for such cases the double-bearing heavy-duty version is recommended. The product is available in various connection combinations (BSP, NPT, BSPT, ACME, welding, PN flanges, ASA, TW, TTMA, grooved joints) and meets PED 97/23/EC, TDT, TÃV, Apragaz. Material: brass. Operating temperature: -40Â°C to +250Â°C. Rotations: slow, oscillating. Working pressure: up to 16 bar.
