Overview of Titanium Gaskets
Titanium gaskets are best known for being strong, lightweight, and corrosion resistant. They are critical to many industries including chlor alkali, marine, off-shore oil & gas, desalination, medical, and pulp and paper. Grade 2 and 5 are the most commonly used grades of titanium gaskets.
Titanium semi-metalic gaskets with a PTFE or graphite soft sealing material are available in the Revoseal JG / JP design which is usable in the most corrosive environments and has a pressure rating of from vacuum to 5800psi / 400bar. WIth a leak rate 15000x less than spiral wound gaskets, you can be sure that hazardous fumes and vapors will be conatained creating the safest work environment possible. Furthermore, our titanium gaskets are customizable and accomodate dissimilar flange faces and large gaps.
Perhaps the most notable attribute of titanium is its superior corrosion resistance to salt water / seawater. Titanium gaskets have the unique ability to rapidly regrow their protective passive layer in the presence of oxygen, giving them unparalleled resistance to salt water environments.
• Proven resistance in decades of polluted seawater
• Usable in ocean depths of a mile beneath the surface
• Resistant to high velocity, rapidly moving currents as well as stagnant seawater
• Not affected by the presence of sulfides in seawater
• Ideal for sea splash and tide zones
• Seawater resistant to temperatures as high as 500°F (260°C)
Chloride, Chlorine & Other Media
Similar to salt water, titanium’s strong, protective oxide film which regenerates in oxygen makes it extremely resistant to oxidizing environments, and chlorides solutions, including hypochlorites, chlorates, perchlorates, sodium chlorite, and chlorine dioxide. This protection holds true as long as moisture is present – which can be as little as 50ppm of moisture. Oxidizing environments in the absence of water can cause titanium to rapidly corrode or even ignite. Titanium gaskets are not resistant to reducing media and acids (see chart).
