Industrial 45° elbows designed to change the direction of piping systems while maintaining the required flow path. Available in butt-weld, socket-weld and threaded configurations according to size, material and application.
45° elbows are available in different connection configurations depending on piping size, installation requirements and applicable specification.
Welded directly to the adjoining pipe to create a continuous piping connection. Commonly used in process, oil & gas and industrial piping systems.
Forged small-bore fitting in which the pipe is inserted into a recessed socket before welding. Suitable for compact welded piping connections.
Mechanical pipe connection using threads. Commonly used for small-bore utility and general industrial piping where a threaded connection is specified.
Material selection can be matched to the required service conditions, temperature, pressure, process media and project specification.

Wall values are nominal pipe-end selection data. Specify the required fitting minimum wall and manufacturing tolerances in the order.
Stainless schedules must be identified with their S suffix where applicable.
Product requirements can be reviewed against the applicable material specification, dimensional standard and purchase order requirements before supply.
Common questions about 45° elbow specifications, connections, materials and sizing.
Rhevon can source 45° elbows in butt-weld, socket-weld and threaded configurations. The applicable connection type depends on the required size, piping specification and application.
Common material options include carbon steel, low- temperature carbon steel, alloy steel and stainless steel. Typical specifications include ASTM A234 WPB, A420 WPL6, A234 alloy grades and A403 stainless steel grades, subject to the required product configuration.
Butt-weld elbows are generally manufactured to applicable ASME B16.9 requirements, while forged socket-weld and threaded elbows are generally covered by ASME B16.11. Material requirements are specified separately according to the required ASTM material specification.
Yes. For butt-weld elbows, the required pipe schedule or wall thickness should be specified in the enquiry. Socket-weld and threaded fittings are specified according to their applicable dimensional and pressure requirements.
Yes. You can submit a mixed requirement containing elbows, tees, reducers, caps, flanges, gaskets, fasteners and other piping components. Rhevon can review the complete Bill of Materials and coordinate the applicable sourcing requirements.
Share your size, schedule, material, connection type, quantity and applicable specification. Mixed piping component requirements are also welcome.
