'absolute sealing'

DIN 2627 stainless steel flanges PN 400 are precision-engineered blind flanges manufactured according to the DIN 2627 standard. Designed to withstand ultra-high-pressure conditions up to 400 bar (5800 psi), these flanges are used to terminate or isolate piping systems safely and effectively. Fabricated from high-grade stainless steels, including 304, 316, and 321, these blind flanges provide superior mechanical strength, corrosion resistance, and long service life in aggressive industrial environments. Ladhani Metal Corporation is a globally recognized manufacturer and exporter of stainless steel flanges. Our DIN 2627 PN 400 blind flanges are widely trusted in sectors such as oil and gas, chemical processing, marine, energy, and high-pressure utility systems for their durability, quality, and performance under extreme conditions. Pressure Rating: • PN 400 (400 bar / 5800 psi): Suitable for high-pressure pipelines and critical systems where absolute sealing and structural integrity are required. Flange Type: • Blind Flanges Solid, non-bored flanges used to block pipeline ends or vessel nozzles. These flanges are essential for system isolation during maintenance, testing, or future expansions. • Flat Face (FF) Flanges Flat face flanges are designed to mate with flat gaskets and flat-faced components. They provide even gasket compression and are ideal when used with cast iron or brittle materials to avoid flange distortion.

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.

Similarly, the electric conductivity of the alloy is low and the electric conductivity of titanium Cold Finished Bar about 3% of copper. 5.Titanium Polished Bar has high flexibility i.e. its Longitudinal elastic modulus. Which means that the flexibility of ASTM B348 Ti Alloy Hex Bar is one half of iron or stainless steel and it is the same as copper.

Material: Gr1, Gr2, Gr5, Gr7, Gr12 etc. OD: 150-2500mm Thickness: 30-250mm Production Methods: Forging,annealing and machining Packing: Plywood box Titanium Tubesheet for Heat Exchanger Product Information Tubesheet is a circular plate drilled with holes of the same diameter as the pipe. 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.

Standard: ASME VIII-I, DIN28013 Material: GR1, GR2, GR5, GR7, GR12 Size: Customized Gr2 Titanium Dish Head Product Information Titanium dish head is the end cap on the pressure vessel and is a main pressure-bearing part of the pressure vessel. The role played is the sealing effect. First, the upper and lower bottoms of the tank-shaped pressure vessel are made, and the second is that the pipe is at the end and is not going to extend forward. Then a titanium dish head is used to seal the pipe in the form of welding. There are blind plates and caps that are similar to the functions of titanium dish head, but those two products can be disassembled. After titanium dish head is welded, it cannot be disassembled. So the quality of titanium dish head is directly related to the long-term safe and reliable operation of the pressure vessel.
