Titanium grade 2 flanges
How much pressure can titanium grade 2 flanges typically withstand?

Titanium grade 2 flanges can withstand pressure conditions up to 20 bars. While characterizing this pressure condition, we need to also keep thermal stressing of titanium, creep possibilities and stress corrosion cracking due to welding in mind.

Pressure less pressure vessel is restricted for loose linings of grade 2 titanium flanges. Loose lining process is however cheaper than cladding process. Cladding process constitutes an advantage to provide protection against wrinkling.

We are authentic UNS R50400 blind and slip-on flange manufacturer in India who complies with ASTM B381, discover titanium gr 2 application

Can UNS r50400 pipe flanges be utilized in high-pressure steam applications?

UNS R50400 pipe flanges are known to yield moderate strength with their minimum yield strength value being 352 Mpa. This is added to a reason because it weighs 4.51 g/cc, which is said to be 60% less than that of a steel and having high tensile strength in the range of 30,000 to 2,00,000 psi. Adding to this, they also have higher melting points than other steel. Hence because of the above-mentioned reasons, it can withstand extreme pressure conditions much higher than the one if you use aluminium or steel for your needs and standards.

As a supplier, specialise in producing titanium alloy grade 2 weld necks and forged flanges to your exact specifications in accordance with ANSI/ASME B16.5, read its testing methods

What are the most widely used standards in the industry for titanium gr 2 weld neck flange?

When specifying titanium gr 2 weld neck flange, below are the standards for this material:

  • ANSI/ASME 16.5: This standard covers ratings for pressure and temperature, dimensions, materials, marking, testing, tolerance abilities, durability, and methods for designating openings for open and closed flanges.
  • B 16.47 Series A & B: This is a standard series of the type ASME B16.47, where ASME B16.47 covers blind and weld neck flanges.
  • B16.48: For the pressure class ratings of 150,300,600,900,1500 and 2500, this standard covers ratings for pressure and temperature of size NPS 1/2 to NPS 24.
  • EN 1092-1: when concerned with nominal pressure and dimensions, an European standard 1092-1 or EN 1092-1 comes into picture where this standard specifies the requirements of the steel flanges.
What is the titanium gr.2 slip on flange minimum order quantity?

There is a huge demand for ASTM B381 titanium gr.2 slip on flange in wide range of industries because of the exceptional properties that it offers. It is also a widely acceptable material. But requirement of this flange depends entirely on its availability. We provide flanges in bulk and also in small amounts.

It also depends on how much quantity is demanded by a customer or an industry to meet his needs or standards. You can also reach out to us if you need any specific product in small quantities, where we would quote best price for you.
