ASTM B861 Titanium Tube

ASTM B861 Titanium tube has good corrosion resistance, which can be used in humid atmosphere and seawater medium, and titanium tube excellent corrosion resistance is much better than that of stainless steel, especially titanium tube ASTM B861 has strong resistance to pitting corrosion, acid corrosion and stress corrosion, and has excellent corrosion resistance to alkali metals and other substances.

Specification

1.1 It may be manufactured by any method(cold rolled, hot extruded, dip hole drilling.etc) that will yield a product meeting the requirements of this specification.
1.2 Unless specified, cold rolled titanium tube shall be heat treated at a temperature of not less than 1000°F (538°C). Hot rolled titanium tube finishing above 1400°F (760°C) need not be further heat treated. The minimum heat treat conditions for Grade 9, 18, and 28 titanium pipe delivered in the stress relieved condition shall be 600°F (316°C) for at least 30 min.
1.2.1 Grade 5, Grade 9, Grade 18, Grade 19, Grade 20, Grade 21, Grade 23, Grade 24, Grade 25, Grade 28, Grade 29,
Grade 35, Grade 36, and Grade 38 alloys may be supplied in the following conditions:
1.2.1.1 Grade 5, Grade 23, Grade 24, Grade 25, Grade 29, Grade 35, or Grade 36-annealed or aged condition,
1.2.1.2 Grade 9, Grade 18, Grade 28, or Grade 38-cold-worked and stress-relieved or annealed,
1.2.1.3 Grade 9, Grade 18, Grade 23, Grade 28, or Grade 29-transformed-beta condition.
1.2.1.4 Grade 19, Grade 20, or Grade 21-solution-treated or solution-treated and aged.

Titanium tube Bending Test

2.1 Titanium tube ASTM B861 size 2 in. (51 mm) and under in nominal diameter, shall be capable of being bent cold through 90° around a cylindrical mandrel which is twelve times the nominal diameter of the pipe, without developing cracks.

2.1.1 Grade 5, Grade 23, Grade 24, Grade 25, Grade 29, Grade 35, Grade 36, and Grade 38 are except from this requirement.

Titanium tube Flattening Test

3.1 ASTM B861 titanium tube shall be capable of withstanding, without cracking, flattening under a load applied gradually at room temperature until the distance between the load platens is H inches. H is calculated as follows:

where:

H = Minimum flattened height, in. (mm),
t = nominal wall thickness, in. (mm) and,
D = nominal pipe diameter, in. (mm) (not pipe size), and
For Grades 1, 2, 2H, 3, 7, 7H, 11, 13, 14, 16, 16H, and 26H.
e = 0.04 through 1 in. pipe size, and
e = 0.06 over 1 in. pipe size.
For grades not shown above, the requirements for the flattening test shall be negotiated between the manufacturer and purchaser.
3.1.1 When low D-to-t ratio tubular products are tested, because the strain imposed due to geometry is unreasonably high on the inside surface at the six and twelve o'clock locations, cracks at these locations shall not be cause for rejection if the D-to-t ratio is less than ten (10).

3.2 All calculations are rounded to two decimal places. Examination for cracking shall be by the unaided eye.

Titanium tube Packaging

The Titanium Tube shall be packaged in agreement with the manufacturer's standard practice(our standard package is export wooden case), unless otherwise agreed to between the manufacturer and purchaser and so stated in the purchase order.

Titanium tube is light in weight, high in strength and superior in mechanical properties. titanium pipe is widely used in heat exchange equipment, such as shell and tube heat exchangers, coil heat exchangers, serpentine tube heat exchangers, condensers, evaporators and pipelines, etc. Many nuclear power industries use titanium tube as standard tubes for their units.

Application case

Titanium tubes that conform to ASTM B861 specification have a wide range of applications due to their excellent mechanical and physical properties. Here are some examples of how titanium tubes are used in various industries:

Aerospace industry:There are commonly used in the aerospace industry due to their lightweight, high strength, and corrosion-resistant properties. They are used in the manufacture of aircraft components such as hydraulic systems, fuel lines, and structural parts.

Chemical processing industry: Titanium pipes are used in the chemical processing industry due to their excellent corrosion resistance, particularly in acidic environments. They are used to transport and process corrosive chemicals and acids.

Medical industry: Titanium Tube ASTM B861 are used in the medical industry due to their biocompatibility, which means they can be implanted into the human body without causing adverse reactions. They are used in the manufacture of medical implants such as artificial joints, dental implants, and pacemakers.

Power generation industry: There are used in the power generation industry due to their high strength and corrosion resistance, particularly in high-temperature environments. They are used in the manufacture of heat exchangers, condensers, and other components in power plants.

Marine industry: There are used in the marine industry due to their excellent corrosion resistance, particularly in saltwater environments. They are used in the manufacture of seawater cooling systems, piping, and other components.
