| Flange Types and Features | |
| Type | Feature |
| Titanium Blind Flange (BL) | BL is a flange without a center hole, used for sealing pipe ends. Available in multiple sealing surface types including flat, raised face, concave-convex, tongue-groove, and ring joint. |
| Titanium Lap Joint Flange (LJF) | The lap joint flange is functionally identical to the sliding flange. Normally used together with lap stubs as a system. |
| Titanium Plate Flange (PL) | Suitable for connecting titanium pipes with nominal pressure not exceeding 2.5 MPa. The sealing surface can be smooth, concave-convex, or tongue-groove type. |
| Titanium Reducing Flange | Used when standard flanges cannot be matched with pipe fittings. The inside diameter differs from a standard flange to accommodate different pipe sizes. |
| Titanium Slip-on Neck Flange (SO) | Pipe slides into the flange before welding internally and externally for sufficient strength to prevent leakage. Bored slightly larger than the pipe outer diameter. |
| Titanium Threaded Flange (TH) | Connected via thread corresponding to the pipe size. Main advantage: can be assembled without welding. |
| Titanium Socket Welding Flange (SW) | Similar to a sliding flange with a counter bore that matches the pipe so the pipe is inserted into the flange before welding. |
| Welding Neck Flange (WN) | Also called “high hub” flange. Transfers pipe pressure to reduce high stress concentration at the flange base. Higher cost due to complex production process. |
