ANSI Flanged Crosses (Class 150)
The one-piece design with PFA or PP lining assures a perfect flow in all four directions. The manufacturing of our one-piece Flanged Crosses is done by injection moulding. For Flanged Crosses with nominal pipe sizes larger than NPS1 4“, we rely on our approved paste liner. Both manufacturing technologies assure a specially smooth and easy-to-clean surface.
Materials:
- carbon steel
- stainless steel
Lining materials:
- up to nominal pipe size NPS1 4“ (one-piece): PFA
- up to nominal pipe size NPS1 4“ (one-piece): PP
- from nominal pipe size NPS1 5“ (one-piece): on request
- from nominal pipe size NPS1 5“ (three-piece): PTFE (virgin or conductive)
Flanges (reading order A-B-C-D):
- combinations of fixed flanges
- combinations of loose flanges
- combinations of fixed and loose flanges
Other pressure rating:
- Class 300
Special features:
- earthing stud/lug
- vent hole extension
- flange stopper
Optional extras:
- final painting
- non-destructive testing

Different nominal pipe sizes
and total lengths 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
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.
