  • carbon steel
  • stainless steel

Lining materials:

  • PTFE (virgin or conductive)

Flanges:

  • loose-loose

Other pressure ratings:

  • on request

Special features:

  • limit bolts/hole extensions
  • earthing stud/lug

Optional extras:

  • final painting

The above shown diagram is only valid at neutral position of the PTFE Expansion Joint with limit bolts in place. The types of travel stroke, lateral offset and angular offset are maximum allowable movements in only one direction. For superpositioned movement the single types of travel need to be limited. The figures stated are average and apply to room temperature.

Different nominal pipe sizes

and total lengths on request.

L = Total length

d4 = Raised face diameter

K = Bolt circle diameter

smin = Minimum flare thickness

a2 = Minimum length with loose flange and smin

Technical data valid for the pressure rating Class 150.
a
2 depends on construction type and lining thickness.
