Is the SJ swivel connector with GW BSP, aluminum suitable for use at 16 bar and temperatures up to +250Â°C?

Yes. The SJ swivel connector with GW BSP, aluminum is specified for operation up to 16 bar and temperatures up to +250Â°C. It is designed for slow or oscillating rotations, for chemical and petrochemical use, and meets PED 97/23/EC and other approvals. Note: it is not resistant to high bending moments.if significant bending loads are expected, choose the double-bearing heavy-duty version.

Can the SJ swivel connector with GW BSP, aluminum be used with flexible hoses in petrochemical installations without transmitting torsional loads?

Yes. The SJ swivel connector with GW BSP, aluminum is specifically designed for connections of rigid or flexible hoses where no torsional moment should be transmitted to other installation elements, and it is used in the chemical and petrochemical industries. It is suitable for slow or oscillating rotations, operating temperatures â40Â°C to +250Â°C, and pressures up to 16 bar. Note: the joint is not resistant to high bending moments; if high bending loads are expected, use the double-bearing heavy-duty swivel joint (available on request).

Does the SJ swivel connector with GW BSP, aluminum resist chemical exposure typical in petrochemical plants?

Probably not reliable for typical petrochemical plant chemical exposures. Explanation: The SJ swivel connector with GW BSP, aluminum Format is specified as aluminum construction and is intended for chemical and petrochemical industry use, with operating temperature â40Â°C to +250Â°C, slow/oscillating rotation and working pressure up to 16 bar. However, aluminum has limited chemical resistance: it can be attacked by strong acids (e.g., hydrochloric, sulfuric), strong alkalis, halogenated hydrocarbons, and certain solvents and process chemicals commonly found in petrochemical service. The product description does not state any specific corrosion-resistant surface treatment (anodizing, protective coating) or alloy grade, nor does it list compatibility with particular chemicals or hydrocarbons. Recommendation: For service involving aggressive acids, caustics, chlorinated solvents or other corrosive media typical in petrochemical plants, specify a swivel joint in a corrosion-resistant material (stainless steel 316/316L, duplex, Hastelloy, or appropriately coated/aluminized versions) or confirm chemical compatibility with the vendor, providing the exact process fluids, concentrations and temperatures. If only mild hydrocarbons and non-corrosive media at the stated temperature/pressure are present, it may be acceptableâbut require vendor confirmation and, if necessary, choice of the heavy-duty double-bearing version for higher bending moments.
