Plate flat welding titanium flange is the most common type of flange, they are made of pure titanium or titanium alloy. Plate welding titanium
flange are commonly used part and pipeline to insert the pipe into the inner hole of the flange to the proper position, and then lap welding.
Plate welding titanium flange sealing surface types include flat and raised panel flat welded flanges. Usually refers to the opening of several
fixing holes on the periphery of a disc-like metal body, which are often used to connect other things. Titanium flanges are used in pairs, and
bolts connect the two flanges.
Titanium flanges have excellent corrosion resistance and high-temperature resistance. Titanium flanges are typically used in the chemical
processing, oil and gas, Marine and aerospace industries.
We offer full-size plate flat welding titanium flange, and also support non-standard customization accordingly to customer’s requirements
or drawings. Our titanium flanges are manufactured critically to the exact standard, including ASME,JIS,DIN,GB,GOST international standards
to meet different requirements from the customers worldwide.
