The inlet and outlet pipes of the high-pressure coal slurry pump are LB 150 ANSI B 16.5 and LB 900 ANSI B 16.5 respectively. If any members know what these designations mean, please explain Thank you
In accordance with ANSI B 16.5, the pipe pressure grades for inlet and outlet applications are 150 pounds and 900 pounds, which correspond to 2 MPa and 15 MPa respectively
The flange standard is ANSI B 16.5; the pressure rating of the inlet flange is 150 lb (PN2.0), while that of the outlet flange is 900 lb (PN15.0). In China, this flange can be replaced with SH3406 or HG-20617-97; the difference between the two is minimal.
ANSI B 16.5 is an American standard; the pipe pressure ratings for import and export are 150 pounds and 900 pounds.
