A titanium blind flange (BL flange) is a flange which has no bore, and is used to close ends of piping systems. A blind flange also permits easy access to a line once it has been sealed. The blind flanges are sometimes machined to accept a pipe of the nominal size to which reduction is being made. The reduction can be either threaded or welded. One of its functions is to block the end of the pipeline, and the other is to facilitate the removal of debris in the pipeline during maintenance. As far as plugging effect is concerned, it has the same effect as the head and cap. But the head can not be disassembled, and the blind flange is fixed by bolts, which is very convenient to disassemble.

Titanium Grade
Tingkat 1
is the most ductile and softest titanium alloy. It is a good solution for cold forming and corrosive environments. ASTM/ASME SB-265 provides the standards for commercially pure titanium sheet and plate.
Grade 2
Unalloyed titanium, standard oxygen.
Grade 2H
Unalloyed titanium (Grade 2 with 58 ksi minimum UTS).
Kelas 3
Unalloyed titanium, medium oxygen.
Grades 1-4 are unalloyed and considered commercially pure or "CP". Generally the tensile and yield strength goes up with grade number for these "pure" grades. The difference in their physical properties is primarily due to the quantity of interstitial elements. They are used for corrosion resistance applications where cost, ease of fabrication, and welding are important.
Grade 5 also known as Ti6Al4V, Ti-6Al-4V or Ti 6-4
Kelas 6
contains 5% aluminium and 2.5% tin. It is also known as Ti-5Al-2.5Sn. This alloy is used in airframes and jet engines due to its good weldability, stability and strength at elevated temperatures.
Kelas 7
contains 0.12 to 0.25% palladium. This grade is similar to Grade 2. The small quantity of palladium added gives it enhanced crevice corrosion resistance at low temperatures and high pH.
Grade 7H
is identical to Grade 7 (Grade 7 with 58ksi minimum UTS).
Kelas 9
contains 3.0% aluminium and 2.5% vanadium. This grade is a compromise between the ease of welding and manufacturing of the "pure" grades and the high strength of Grade 5. It is commonly used in aircraft tubing for hydraulics and in athletic equipment.
Kelas 11
contains 0.12 to 0.25% palladium. This grade has enhanced corrosion resistance.
Grade 12
contains 0.3% molybdenum and 0.8% nickel. This alloy has excellent weldability.
Grades 13, 14, and 15
all contain 0.5% nickel and 0.05% ruthenium.
Grade 16
contains 0.04 to 0.08% palladium. This grade has enhanced corrosion resistance.
Grade 16H
is identical to Grade 16 (Grade 16 with 58ksi minimum UTS).
Grade 17
contains 0.04 to 0.08% palladium. This grade has enhanced corrosion resistance.
Grade 18
contains 3% aluminium, 2.5% vanadium and 0.04 to 0.08% palladium. This grade is identical to Grade 9 in terms of mechanical characteristics. The added palladium gives it increased corrosion resistance.
Grade 19
contains 3% aluminium, 8% vanadium, 6% chromium, 4% zirconium, and 4% molybdenum.
Grade 20
contains 3% aluminium, 8% vanadium, 6% chromium, 4% zirconium, 4% molybdenum and 0.04% to 0.08% palladium.
Grade 21
contains 15% molybdenum, 3% aluminium, 2.7% niobium, and 0.25% silicon.
Grade 23 also known as Ti-6Al-4V-ELI or TAV-ELI
Grade 24
contains 6% aluminium, 4% vanadium and 0.04% to 0.08% palladium.
Grade 25
contains 6% aluminium, 4% vanadium and 0.3% to 0.8% nickel and 0.04% to 0.08% palladium.
Grades 26, 26H, and 27
A hexagon formed from thermal stir welding of a Titanium alloy
all contain 0.08 to 0.14% ruthenium.
Grade 28
contains 3% aluminium, 2.5% vanadium and 0.08 to 0.14% ruthenium.
Grade 29
contains 6% aluminium, 4% vanadium and 0.08 to 0.14% ruthenium.
Grades 30 and 31
contain 0.3% cobalt and 0.05% palladium.
Grade 32
contains 5% aluminium, 1% tin, 1% zirconium, 1% vanadium, and 0.8% molybdenum.
Grades 33 and 34
contain 0.4% nickel, 0.015% palladium, 0.025% ruthenium, and 0.15% chromium. Both grades are identical but for minor difference in oxygen and nitrogen content.[30] These grades contain 6 to 25 times less palladium than Grade 7 and are thus less costly, but offer similar corrosion performance thanks to the added ruthenium.
Grade 35
contains 4.5% aluminium, 2% molybdenum, 1.6% vanadium, 0.5% iron, and 0.3% silicon.
Grade 36
contains 45% niobium.
Grade 37
contains 1.5% aluminium.
Grade 38
contains 4% aluminium, 2.5% vanadium, and 1.5% iron. This grade was developed in the 1990s for use as an armor plating. The iron reduces the amount of Vanadium needed as a beta stabilizer. Its mechanical properties are very similar to Grade 5, but has good cold workability similar to grade 9.
