Titanium Flange
Titanium Flange
Nippon Titanium offers a wide range of titanium alloy flanges including slip-on, blind, weld becks, orifice, and lap and joint flanges. Titanium flanges can be used in cars, medical equipmentpetrochemical equipment. Nippon Titanium has rich experience in forging and machining, which makes our titanium flange products kept good quality. At the same time, to meet the specific requirements of customers, we also produce titanium flange according to customer drawings.

| Flange Types and Feature | |||||||||||
| Type | Feature | ||||||||||
| Titanium Blind Flange (BL) | BL is the middle of the flange without hole, for sealing the pipe plug. There are many types of sealing surface, including plane, convex surface, concave and convex surface,tenon groove surface and ring connecting surface. | ||||||||||
| Titanium Lap Joint Flange (LJF) | The lap joint flange is actually identical to the sliding flange. Normally, lap joint flanges and lap stubs are together will be the system. | ||||||||||
| Titanium Plate Flange（PL） | The Plate Flange is suitable for connecting titanium pipes with nominal pressure not exceeding 2.5mpa. The sealing surface of the plate flange can be made into smooth type, concave and convex type, tenon groove type. | ||||||||||
| Titanium Reducing Flange | There is a certain difference between the inside diameter of reducing flange and that of standard flange. In engineering, when the standard flange cannot be matched with pipe fittings and pipes, the variable diameter flange is used instead. | ||||||||||
| Titanium Slip-on Neck Flange (SO) | The sliding flange has a lower hinge as the pipe enters the single flange before welding.It is welded internally and externally to provide sufficient strength to prevent leakage.The sliding flanges are all bore to match the slightly larger outer diameter pipe. | ||||||||||
| Titanium Threaded Flange (TH) | The threaded flange is connected with a thread. However, the center of the product has a thread size corresponding to the pipe. Its main advantage is that it can be assembled without welding. | ||||||||||
| Titanium Socket Welding Flange (SW) | The socket welding flange is a similar sliding flange unless it has a hole and reverse hole dimensions. The counter hole matches the pipe so that the pipe is inserted into the flange similar to the sliding flange. | ||||||||||
| Welding Neck Flange (WN) | Weld Neck Flange is usually called “high hub” flange. Its purpose is to transfer the pressure of the pipe, thereby reducing the high stress concentration in the flange base. However, the price is high, because the production process is complex. | ||||||||||
