Is the SJ swivel coupling with GW BSP, stainless steel suitable for conveying corrosive chemicals at up to 16 bar and temperatures between -40Â°C and +250Â°C?

Yes . the SJ swivel coupling with GW BSP, stainless steel is suitable for conveying corrosive chemicals at up to 16 bar and temperatures between â40Â°C and +250Â°C, with the following caveats: - Material: made of AISI 316 stainless steel, which offers good corrosion resistance to many corrosive chemicals; suitability depends on the specific chemical and its concentration . confirm compatibility with AISI 316 for your media. - Pressure/temperature: rated working pressure up to 16 bar and operating temperature range â40Â°C to +250Â°C, so it meets your stated conditions. - Mechanical loads: designed for slow, oscillating rotations and transfers no torsional moment; it is not resistant to high bending moments. If the installation will impose significant bending or dynamic loads, specify the heavy-duty double-bearing swivel joint instead. - Certification: meets PED 97/23/EC and has TDT, TÃV, Apragaz approvals. Recommendation: verify chemical compatibility of AISI 316 with your specific chemicals (and concentrations/temperatures) and assess whether bending or dynamic loads require the double-bearing heavy-duty version.

Can the SJ swivel coupling with GW BSP, stainless steel be used where zero torsional transmission to downstream equipment is critical?

Yes. The SJ swivel coupling with GW BSP, stainless steel is specifically designed to prevent torsional moments from being transmitted to downstream equipment, making it suitable where zero torsional transmission is critical. It features a single bearing for connecting rigid or flexible pipes and is used in chemical and petrochemical applications. Note: it is not suited for high bending moments; if significant bending loads are present, choose the heavy-duty double-bearing version (available on request). Specs: AISI 316, -40Â°C to +250Â°C, slow/oscillating rotations, up to 16 bar, meets PED 97/23/EC, TDT, TÃV, Apragaz.

Does the SJ swivel coupling with GW BSP, stainless steel require lubrication for reliable slow or oscillating rotation?

No. the SJ swivel coupling with GW BSP, stainless steel does not require additional lubrication for reliable slow or oscillating rotation under normal operating conditions. The design features a single bearing intended for slow or oscillating movement and is specified for use in chemical and petrochemical installations up to 16 bar and temperatures from â40 Â°C to +250 Â°C. For applications with higher bending moments or continuous heavy-duty rotation, a swivel joint with a double bearing (heavy duty) is recommended, but for the stated slow/oscillating duty the standard SJ swivel coupling with GW BSP, stainless steel is suitable without special lubrication.
