Engineered for reliable directional flow across critical industrial piping systems.
Sizes & dimensional standards ↓FERROBEND supplies butt weld elbows (also called buttweld elbows) for changing the direction of flow in industrial piping systems. Standard and project-specific configurations can be considered across stainless steel, duplex, super duplex, carbon steel, alloy steel, nickel alloys, titanium and copper alloys.
Products can be supplied according to applicable ASME, ASTM, MSS, EN and project specifications, subject to material grade, dimensions, wall thickness and manufacturing feasibility.
Manufacturing configurations may include seamless elbows, welded elbows and fabricated configurations where applicable. Not every material, size or geometry is available by every manufacturing route.

D denotes the nominal pipe size designation, not the measured outside diameter. LR/SR ratios are typical geometry descriptions, not a substitute for standard dimension tables. Confirm centre-to-end dimensions and tolerances against the applicable standard. Custom radius or geometry requires an approved drawing and feasibility review.
Standard dimensional coverage up to NPS 48 in accordance with applicable standards. Actual manufacturing and supply range depends on material, wall thickness, configuration and project requirements.
Schedule availability depends on nominal size, material, manufacturing route and applicable standard. The list does not imply that every schedule exists in every size or material. Custom wall thicknesses may be considered against project requirements; heavy-wall configurations are subject to manufacturing feasibility.

Supply according to the applicable material and project specification.
Typical grades are enquiry options, not a statement of stock or universal suitability. Material, size, wall thickness and manufacturing route must be confirmed together for the intended service.
Inspection requirements are performed in accordance with the applicable material specification, purchase order, approved ITP and project requirements.
Testing is performed as required by the applicable material specification, customer purchase order, project specification or approved inspection and test plan.
Not every elbow receives every test. Test methods, acceptance criteria, witnessing and reporting requirements should be agreed in the purchase order and approved ITP.
Documentation is supplied according to applicable specification and customer/project requirements. The following records may be supplied as applicable; they do not automatically accompany every order.
Material traceability can be maintained from raw material through manufacturing, inspection and final documentation according to applicable quality and project requirements.

To receive an accurate quotation, please specify:
Specify the pipe size, wall thickness or schedule, elbow angle, radius configuration, material grade and applicable standard. Include the quantity and any drawing-specific requirements.
The radius describes the curvature of the elbow. Long and short radius configurations have different centreline bend radii and installation dimensions. Confirm the required configuration against the approved piping layout and fitting standard.
State the required angle in the enquiry. Include a drawing for special angles or dimensions so the geometry and manufacturing requirements can be reviewed.
List the certificates, inspection, testing and marking required by the project specification. Confirm that scope with the quotation rather than assuming every requirement is included.
Send FERROBEND your size, schedule, material grade, angle, radius, quantity, applicable standard and inspection requirements for technical and commercial review.
