Flange Types & Facings

Flange Types We Machine
TypeTypical use
Weld neck (WN)High pressure / temperature piping; butt-weld hub
Slip-on (SO)Low-pressure process lines, easy fit-up
Blind (BL)Vessel closures, test plugs
ThreadedNo-weld sites, instrument connections
FacingRaised face (RF), flat face (FF), RTJ per class

Standards

ASME B16.5 (NPS/class), EN 1092-1 (DN/PN), HG 20592/20615 for Chinese chemical-industry practice. Tell us standard + size + class; we machine to the facing detail you name.

Sizes & Pressures

Rather than publish a grid we cannot hold, flange enquiries are quoted against your schedule: NPS/DN, class/PN, facing, quantity, and the tube OD it mates to (we consolidate tube + flange orders routinely).

From Tube to Flange — Matched Orders

Piping projects buy the run and the termination together: tube, elbows, and flanges in one container, same heat traceability chain. Our custom supply service covers the multi-material version of the same job.

FAQ

Do you keep standard flanges in stock?
Flanges are machined to order; some common Gr2 classes repeat enough to shorten lead time. Send size + class for the current answer.
Can you make non-standard flange dimensions?
Yes — drawing or sample based, including drilling patterns outside B16.5.
Do you supply gaskets and bolts with flanges?
Bolts and nuts: yes, see fasteners. Gasket supply depends on the spec.
Titanium vs steel flange — worth it?
Where chloride pitting or weight matters (marine, chemical), yes. Cost per piece is higher; life-cycle usually isn't. Selection guide.
