Seek titanium flange standards
Thread Content
The customer needs titanium flanges with material TA2, DN25-PN40-RF, but titanium does not fall within the scope of the standards HG/T20592-2009 and EN 1092. Could anyone provide information on the standards applicable to titanium flanges? Polygenic
What you are looking for are the material standards, not the design standards for the flange shape.
I’m looking for flange standards that cover titanium materials; just having the material standards isn’t enough to determine the dimensional specifications of the flanges
Then take your time looking for it. The flange dimensions follow standard specifications such as ASME B16.5, and the materials can be carbon steel, stainless steel, nickel-based alloys, or CPVC. . .
Just design and manufacture it according to the standard flange specifications, with titanium chosen as the material.
For non-ferrous metals, there are no industry standards or **standards** regarding flanges. . . For this requirement, the purchaser shall design and calculate it themselves. . . Either the shape, size, and pressure rating must all be the same as those of steel versions, with only the material being changed to what you require. .
If the flange material is pure titanium, design can be carried out by referring to the dimensions specified in standards HG/T20592-2009~HG/T20615-2009. In the case where the flange is made of carbon steel while the lining ring is made of titanium, one can refer to the dimensions for loose-flange designs outlined in standards HG/T20592-2009~HG/T20615-2009.
Refer to HG/T 3651-1999
Thank you all for your help. In the end, the HGT20592 standard was adopted. After checking online, it was found that if the mechanical properties of the material used are better than those specified for steel flanges, it is possible to use the dimensional specifications of those flanges directly. Thank you very much to everyone! ! !
Hello, original poster. Have you managed to find the allowable stress for titanium flanges? From what I’ve checked, it seems that the allowable stress for titanium is higher than that for steel
