Product Description

ASTM B381 GR1 GR2 GR5 GR7 GR12 Titanium blind flange for chemcial industry

 Due to the excellent corrosion resistance of titanium material, the pure titanium flange is much used for connecting the tube ends of the petrochemical project. It is also useful in equipment exit and entrance to connect the two devices.

Titanium alloy has the characteristics of light weight, high strength and good corrosion resistance, so titanium alloy flange is often used in oil drilling, marine engineering, machinery and equipment manufacturing industry in the key pressure parts of the connection.

Giant Metal 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 type:
Welding plate flange(PL)
Slip-on Neck Flange (SO)
Welding neck flange (WN)
Integral flange (IF)
Socket welding flange (SW)
Threaded flange (Th)
Lapped joint flange (LJF)
Blind flange (BL(s))
We can also according to the drawing processing.
