Elbow Types & Standards

↪

90° Long Radius (LR) Elbow

Centreline radius = 1.5D. Most common elbow type. Lowest pressure drop — preferred for process piping where space permits.

  • ✓ ASME B16.9
  • ✓ EN 10253 Type A & Type B
  • ✓ MSS SP-43 (lightweight)
↩

90° Short Radius (SR) Elbow

Centreline radius = 1.0D. Compact layout where space is limited. Higher pressure drop than LR. ASME B16.28 coverage.

  • ✓ ASME B16.28
  • ✓ EN 10253 Type A & Type B
  • Note: higher ΔP — confirm with engineer
↙

45° LR Elbow

Half-angle elbow for gradual direction changes. Lower turbulence than 90°. Used in combination with 90° elbows for offset runs.

  • ✓ ASME B16.9
  • ✓ EN 10253 Type A & Type B
🔄

180° Return Bend (LR)

U-bend returning flow 180°. Used in heat exchangers, serpentine coils and compact piping arrangements.

  • ✓ ASME B16.9
  • ✓ EN 10253 coverage
🔃

180° Return Bend (SR)

Compact U-bend with 1.0D radius. For tight serpentine coils and heat exchanger manifolds with space constraints.

  • ✓ ASME B16.28
  • ✓ EN 10253 coverage

EN 10253 Type B Elbows

Elbows to EN 10253 Type B are for use at full service pressure, with the same strength as the connecting pipe of the same material and wall thickness. They often need extra wall thickness to achieve this. Type A also supplied. On request we machine the ends to match the bore of your pipe.

Specifying EN 10253 Type B Elbows?

Type B elbows are for use at full service pressure. Type A elbows have a reduced pressure factor that the design must allow for. The pressure-equipment designer chooses the type. Arshya is one of the very few Indian manufacturers certified to supply Type B across all material families, and we supply Type A too. Always state "EN 10253 Type A" or "EN 10253 Type B" clearly in your RFQ.
