Titanium sheet metal are commonly used in today's manufacturing industry, and the most commonly used grades are 2 and 5. Grade 2 titanium Grade 2 is commercial pure titanium used in most chemical processing plants and can be cold formed. Ultimate tensile strength of grade 2 plates and sheets up to 40,000 psi and above. Grade 5 titanium Class 5 is an aerospace class that does not allow cold molding and is therefore used more often when molding is not required. Grade 5 aerospace alloys have ultimate tensile strength of 120,000 psi and above. Usually the purpose of using Titanium sheet metal is to really approximate the final size of the part being manufactured. The material is processed to the nearest size of the required parts and the grain structure of the finished product is more uniform. Titanium plates are often used as insulation because titanium prevents heat from being transferred to the rest of the assembly. The titanium plate and titanium plate are bulletproof and provide good protection for the driver during the race. Application example: in addition to the use of industrial pure titanium manufacturing parts, a large number of titanium alloy is used. It is increasingly widely used in aerospace, aerospace, chemical, shipbuilding and other industrial sectors, manufacturing gas turbine components, the production of prosthetic devices and other biological materials

Product Name: Titanium Gr 2 flanges Standard: ASME B16.5 Material: Gr2 Unit Price: $25usd/pc-$85usd/pc Sealing Surface: RF, FF, TG, RJ etc. Size: NPS 1/2 - NPS 24(DN 10 - 2000) Pressure: 150#-2500# Grade 2 titanium is the most commonly requested in the pipeline valve and fittings industry, with high strength and corrosion resistance. Titanium is generally used in applications that require high temperature and high pressure service but are lighter in weight. Some good examples are components in the aerospace industry (airframe frames) and state-of-the-art equipment in the military. Given its excellent corrosion resistance in marine and chloride applications, titanium flanges are also popular as offshore drilling components and heat exchanger components. When you need a metal with good overall formability and workability, please choose titanium. It has the capability of hot or cold forming while maintaining its excellent mechanical properties. For transportation to your work site, it is good to know that titanium is much lighter than regular steel (about 40-45% lighter). Although not as light as aluminum, our titanium flanges and fittings are easier to handle during welding and installation.

It is used for the heat exchanger to fix the pipe. An accessory that accomplishes this by passing a pipe through and welding it in place. The precision of tubesheet processing, especially the tolerance of tube hole spacing and diameter, verticality and finish, have a great impact on the assembly and performance of the above-mentioned chemical equipment. With the enlargement of chemical equipment and power stations, the diameter of tubesheets has become larger and larger. Tubesheet with a diameter of 4m-5m is very common. The characteristics of large tubesheet are many tube holes, compactness, small hole diameter, deepness, high precision, and high finish requirements.
