ANSI Lined Pipes (Class 150)
Our pipes are lined, totally strainless, with paste-extruded PTFE and fully automatically tested. Depending on the nominal pipe size, we produce pipes up to a total length of 6 metres.
Materials:
- carbon steel
- stainless steel
Lining materials:
- PTFE (virgin or conductive)
- PP PP (up to nominal pipe size NPS 12“)
Flanges
- fix-loose
- fix-fix
- loose-loose
Other pressure rating:
- Class 300
Special features:
- earthing stud/lug
- vent hole extension
- flange stopper
Optional extras:
- final painting
- non-destructive testing

Nominal pipe sizes over NPS 20“
up to NPS 1000“ on request.
L = Total length
Lmin = Minimum total length with flanges fix-loose
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
a2 = Minimum length with loose flange and smin
Technical data valid for the pressure rating Class 150.
a1 and a2 depend on construction type and lining thickness.
