A 180-degree return bend redirects a line back toward the incoming direction. This enquiry focuses on the long-radius carbon-steel return and B16.9 requirements named in the title. Confirm the selected return geometry and pipe interfaces before choosing a model, since general elbow options and mixed bend images do not define every listed configuration.
Draw the return layout and envelope
Provide the required angle, centreline radius and relationship between both pipe ends. Include the overall envelope, tolerances and available installation space on the drawing. Confirm whether the proposed item is one return fitting and identify any assembly joints. State both end sizes and explain what the millimetre option measures so the intended pipe arrangement can be reviewed without assuming a nominal size or radius from a photograph.
Specify the wall and exact material
Give the mating pipe outside diameter, wall thickness or schedule and required weld preparation. Choose the carbon-steel variant and specify its exact grade and governing material requirements; the family label does not establish a material grade. Stainless-steel and alloy alternatives require separate designations and records. If custom dimensions are needed, agree them for the selected model rather than treating a general custom-size field as a confirmed capability.
Define conformity and joint acceptance
Identify the B16.9 edition and required dimensional acceptance, then request material, production and inspection records covering the item offered. Evidence is needed for any specific manufacturing requirement. Provide the fluid, operating pressure and temperature alongside fabrication and examination requirements for the welded return. Assess the chosen geometry, wall and complete joint together; a standalone Pipe Class field does not establish allowable service. The enquiry should link one agreed return drawing to traceable material and documented duty conditions.
