DIN Flanged Reducers concentric (PN 10)

Concentric Flanged Reducers are the universal solution for all changes of the nominal pipe size. Depending on the nominal width, the reducers are lined with PTFE, PFA or PP.

Materials:

  • carbon steel
  • stainless steel

Lining materials:

  • PTFE (virgin or conductive)
  • PFA (virgin or conductive)
  • PP

Flanges according to EN 1092-1:

  • fix-fix
  • fix-loose
  • loose-loose

Other pressure levels:

  • PN 16
  • PN 25
  • PN 40

Special features:

  • earthing stud/ lug
  • vent hole extension

Optional extras:

  • final painting
  • non-destructive testing

The nominal pipe size combinations printed in bold are manufactured in two parts with flanges fix-fix or fix-loose in which the loose flange is generally on the DN1 side.


Different nominal pipe sizes, total lengths and
other construction types on request.

L = Total length

d1 = Outer diameter of the pipe

d4 = Raised face diameter

K = Bolt circle diameter

smin = Minimum flare thickness

a1 = Minimum length with fixed flange and smin
(one-piece: Type 11, two-piece: Type 011)

a2 = Minimum length with loose flange and smin

(one-piece: Types 04/34, two-piece: Types 02/32)

Technical data valid for the pressure level PN 10.

a1 and a2 depend on construction type and lining thickness.
