DIN 86029 PN10 Hubbed Slip On Flanges for Welding

DIN 86029 PN10 Hubbed Slip On Flanges Manufacturer

DIN 86029 PN10 Hubbed Slip-On Flanges for Welding are a specific type of pipe flange standardized under German DIN norms, primarily used in marine engineering, shipbuilding, and related water systems.

DIN 86029 Standard & Scope

  • Standard: DIN 86029
  • Application: Typically used for welding to the pipe end, forming a tight, secure joint.
  • Industry: Marine systems, ship piping, seawater pipelines, and industrial water systems.

DIN 86029 Pressure Rating

  • PN10 → Nominal Pressure 10 bar (≈ 145 psi) at 20 °C.
  • Suitable for low to medium pressure pipelines.

DIN 86029 Flange type

  • Hubbed Slip-On Flange for Welding:
    • Has a short cylindrical hub.
    • Slips over the pipe end and is welded both inside and outside (fillet welds).
    • Ensures strength and leak-tightness.

DIN 86029 Dimensions

DIN 86029 specifies DN (nominal diameter) sizes usually from DN 10 up to DN 600.
Main dimensions per standard include:

  • D – Outside diameter
  • K – Bolt circle diameter
  • d₂ – Hub bore diameter (matching pipe OD)
  • b – Flange thickness
  • f – Raised face height (if applicable)
  • Number of bolt holes & bolt size per PN10 table.

Example for DN 100, PN10 (approximate, check standard for exact):

  • D: 220 mm
  • K: 180 mm
  • b: 18 mm
  • Bolt holes: 8 × M16

DIN 86029 Flange Materials

Commonly manufactured in:

  • Carbon steel: e.g., C22.8, P235GH, S235JR
  • Stainless steel: e.g., 1.4404 (316L), 1.4541 (321)
  • Bronze / Copper alloys for seawater applications (in marine industry).
