Many people may not have a deep understanding of titanium flanges. I will take you to systematically and quickly understand what titanium flanges are, hoping to be helpful to you.

Titanium flange is a type of connecting pipe structure made of non-iron or titanium alloy. The titanium flange has holes and two flanges are tightly connected. The flange is sealed with a gasket. Flange pipe parts refer to pipe fittings with flanges (joints or fittings).

Can form threaded connections or welded joints. The flange joint consists of a pair of flanges, a gasket, and several bolts and nuts. The gasket is placed between two flange covers. After tightening the nut, when the surface pressure of the gasket reaches a certain value, the sealing surface is filled unevenly and the connection is tight.

According to structural form, it can be divided into titanium flanges, butt welded titanium flanges, threaded titanium flanges, blind plate titanium flanges, etc.

Product specifications: Various specifications can be produced according to flange standards, or specified non-standard flanges can be produced according to customer provided drawings.

Manufacturing methods: free forging, die forging, precision forging, welding.

Inspection methods: X-ray testing, staining, flaw detection, water pressure testing, etc. can be carried out according to customer needs.

Materials: TA1/Gr1, TA2/Gr2, TC4/Gr5, Grade9, Grade11, Grade12, titanium alloy flange.

Performance characteristics:

As a new type of metal, the properties of titanium based metals are related to elements such as carbon, nitrogen, hydrogen, and oxygen. Generally speaking, there are the following characteristics:

1. High strength

The density of titanium material is generally 4.51g per cubic centimeter, which is only 60% of that of steel. The density of pure titanium is similar to that of ordinary steel, and the strength of some high-strength titanium alloys is higher than that of many alloy structural steels. So, the specific strength (strength/density) of titanium alloy is much higher than that of other metal structural materials.

2. High thermal strength;

Under medium temperature conditions, titanium alloys can still maintain the required strength and can work for a long time at 450-500 ℃.

3. Good corrosion resistance.

Titanium alloy works in humid atmospheres and seawater media, and its corrosion resistance is far better than stainless steel, which has particularly strong pitting, acid corrosion, and stress corrosion, such as alkalis, chlorides, chlorine organic compounds, nitric acid, sulfuric acid, etc.

4. Good low-temperature performance.

Titanium alloys can still maintain their mechanical properties under low and ultra-low temperature conditions. TA7 is a titanium alloy with excellent low-temperature performance and extremely low interstitial elements, which can maintain a certain degree of plasticity at -253 ℃. So titanium alloy is also an important low-temperature structural material.

5. High chemical activity.

Titanium has extremely high chemical activity and is associated with oxygen in the atmosphere N. H.CO.CO_ 2. Steam, ammonia, etc. have strong chemical reactions. When the carbon content is greater than 0.2%, hard TiC is formed in titanium, and a hard TiN surface is formed at high temperatures. At temperatures above 600 ℃, titanium can absorb oxygen and form a hard hardening layer; At high temperatures, as the hydrogen content increases, a hard hardening layer forms. After inhalation, the depth of the hard and brittle surface can reach 0.1-0.15mm, and the hard and brittle surface can reach 20%~30%. Its chemical affinity is also strong, making it easy to adhere to the friction surface.

6. Low thermal conductivity and elasticity.

The thermal conductivity of titanium series is about 1/4 of nickel, 1/5 of iron, and 1/14 of aluminum. The thermal conductivity of various titanium alloys is around 50%. The elastic modulus of titanium material is about half of that of steel, with poor stiffness and easy deformation, making it unsuitable for slender rods and thin-walled parts.
