This 90-degree butt-weld elbow enquiry requires the material and governing specification to be clarified alongside its dimensions. The title contains EN 10253-3 and ASTM A105 references, and the available options include carbon steel and stainless steel. Ask which reference applies to the selected item before treating those labels as a combined statement of conformity.
Assign the material and governing reference
Identify one offered variant, its exact grade and the specification under which it will be supplied. Request a clear explanation of the EN 10253-3 and ASTM A105 references for that construction. The A105 requirement and Casting table label also need reconciliation through material and manufacturing records. If the offered specification differs from the project requirement, obtain an explicit engineering decision; avoid silently substituting a grade, production route or standard.
Describe the selected elbow dimensions
Provide the required 90-degree angle and ask for its measured acceptance on a model drawing. Include centreline radius, end-to-centre dimensions, nominal size, outside diameter and wall thickness. Confirm equal-end geometry and explain what the millimetre-labelled size option represents. Define bevel, land and end wall against the mating pipe so the actual butt-weld interface can be reviewed. A generic male female field does not replace those end details or prove a threaded connection.
Connect inspection with the project duty
State the governing editions and dimensional, material and inspection acceptance requirements. Supply the fluid, operating pressure and temperature, corrosion conditions and joining requirements for assessment of the complete connection. The Pipe Class 150 field does not establish its allowable pressure-temperature duty. Likewise, Painting and mounting-hole labels do not demonstrate a protective coating or measured elbow geometry. The enquiry should finish with a selected material-standard assignment, one dimensional drawing and traceable production and inspection evidence.
