BHDT COMPACT FLANGES
ACC. NORSOK L-005

Compact Flanges offer outstanding benefits whenever size,
weight and stress are critical factors in pipe-design. Compared
to ANSI Flange connections, Compact Flanges save up to 80 %
of weight withstanding high bending and tension loads without leaking. Therefore, no retightening of bolts is required! Compact Flange metal to metal connection with special steel seal rings ensure a 100 % leakfree connection by having three sealing surfaces in one joint.

Compact Flanges are designed as a complete closing static connection, keeping corrosion problem causing medium away from the sealing surfaces and bolts which ensures longlife usage under extreme conditions. BHDT offers Weld-Neck-, Swivel-, Blind- and Intergal Flange Connections as specified in NORSOK L-005 NCF5 and NCF4 Standard. For any requirement BHDT provides Compact Flange design acc. NORSOK L-005 in combination with Analytical Calculation, Finite Element Analysis, Design Verification acc. DIN EN 13445-3 and AMSE and Approval by Notified Bodies like Det Norske Veritas, TUV or others.

Norsok M-630, M-650 and DNV-OS-E201 are also applicable.
