Introduction of titanium flange?
Titanium flange， made of nonferrous metal titanium or titanium alloy， is manufactured as the connected parts between tubes. The titanium flanges with holes can be tight by using bolts and gasket between flanges. Flanged pipe fitting refers to the pipe fitting with flange (flange or joint).
It may be made up of threaded connections or welding. The flange joint consists of a pair of flanges, a gasket and a number of bolts and nuts. The gasket is placed between the sealing surfaces of two flanges. After the nuts are tightened, the specific pressure on the gasket surface reaches a certain value in order to produce deformations. The gasket surface is filled with the uneven parts on the sealing surface to ensure the tight connection.
According to the structure, there are flat-welded titanium flange, butt welded titanium flange, threaded titanium flange and blind titanium flange.

Titanium is a new type of metal which the performance is related to the content of carbon, nitrogen, hydrogen, oxygen and other impurities. Generally speaking, it has the following characteristics:
1. High intensity
The density of titanium alloy is generally approximate to 4.51g/ cm3, which is only 60% of steel. The density of pure titanium alloy is close to the ordinary steel. Some high-strength titanium alloys exceed the strength of some other alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much higher than the other metal structural materials.
2. High thermal intensity
Titanium alloy can maintain the required strength at medium temperature , which can work for a long time at 450 ~ 500℃.
3. Better corrosion resistance
The corrosion resistance of titanium alloy is better than the stainless steels when it works in humid atmosphere and ocean, especially in pitting, acid corrosion and stress corrosion. Titanium has excellent corrosion resistance in alkali, chloride, chlorine organic goods, nitric acid, sulfuric acid.
4. Better performance at low temperature
The mechanical properties of titanium alloy can be maintained perfectly at low temperature and ultra-low temperature. Titanium alloys with excellent low temperature performance and low clearance elements, such as TA7, can still maintain certain plasticity at -253℃. Therefore, titanium alloy is also an important low temperature structural material.
5. High chemical activity
Titanium has strong chemical reactions with O, N, H, CO, CO2, water vapor, ammonia in the atmosphere because of great chemical activity. When the carbon content is greater than 0.2%, TiC will be formed in titanium alloy. When the temperature is high, the TiN hard surface will be formed by the action with N. At temperature above 600℃, titanium absorbs oxygen to form a hardened layer with high hardness. As the hydrogen content increases, the embrittlement layer can be also formed. The surface depth of hard and brittle caused by the absorption of gas can reach 0.1 ~ 0.15mm, and the degree of hardening is 20% ~ 30%. The chemical affinity of titanium is also active and easy to produce adhesion with the friction surface.
6. Low heat conduction elasticity
The thermal conductivity of titanium =15.24W/ (m.K) is approximately 1/4 of nickel, 1/5 of iron, and 1/14 of aluminum, while the thermal conductivity of various titanium alloys is approximately 50% lower than titanium. The elastic modulus of titanium alloy is about 1/2 of steel, so its rigidity is poor and easy to be deformed, which is not suitable to manufacture as slender rods or thin-walled parts.
