Titanium Flat Welding Flange

Titanium flat welding flange is a structural pipe connection component designed for welding attachment to pipelines, pressure vessels, and industrial equipment. It is typically joined to the pipe by fillet welding, forming a reliable sealing interface for medium- and low-pressure systems.

Depending on structural design requirements, the connection between the flange ring and straight section may be classified as integral or loose-type construction, and can be supplied with neck or without neck.

Compared with butt-weld neck flanges, titanium flat welding flanges feature a simpler structure, reduced material consumption, and easier installation, making them a cost-effective solution for industrial piping systems.

STRUCTURAL DESCRIPTION

A titanium flat welding flange is installed at the pipe end and connected via bolt assembly. The system consists of:

A pair of titanium flanges

Gasket sealing element

Bolts and nuts for tightening and load distribution

The flange contains bolt holes evenly distributed along its circumference, enabling secure mechanical fastening and pressure-tight sealing.

APPLICATIONS

Titanium flat welding flanges are widely used in industrial piping and pressure systems requiring corrosion resistance and structural reliability, including:

Chemical processing and corrosive fluid pipelines

Oil and gas transportation systems

Marine engineering and offshore structures

Seawater desalination plants

Medium and low-pressure pressure vessels

Heat exchange and industrial reactor systems
