Product Introduction
Grade 2 titanium tube is a commonly used grade in the chemical
industry. The ASTM B861 standard specification outlines the
requirements for Grade 2 titanium tube and other titanium alloys,
encompassing a total of 34 grades of titanium and titanium alloy
seamless pipes intended for general corrosion resistance and
high-temperature service. Seamless and welded pure titanium pipes,
ranging from 0.405" (10.29mm) to 36" (914mm), are available in
stock in pre-cut lengths and full lengths.
Titanium is a metal with high ductility and malleability, allowing
us, as one of China's titanium tube factories, to produce
components in various shapes, including round, oval, and even
square pipes. The products produced according to the ASTM B861
specification are designed to perform well in applications where
general corrosion resistance and strength at elevated temperatures
are primary requirements.

Titanium Tube Test Measures
Bending Test
According to ASTM B861, titanium tubes with a nominal diameter of 2
in. (51 mm) and under should be able to be bent cold through 90°
around a cylindrical mandrel that is twelve times the nominal
diameter of the pipe without developing cracks.
Hydrostatic Test
The maximum hydrostatic test pressure must not exceed 2500 psi
(17.2 MPa) for tube sizes 3 in. (76 mm) and under, or 2800 psi
(19.3 MPa) for sizes above 3 in. (76 mm). The hydrostatic pressure
must be maintained for no less than 5 seconds. When requested by
the purchaser and stated in the order, Grade 2 titanium tubes with
diameters of 14 in. (356 mm) and smaller should be tested at one
and a half times the specified working pressure, provided that the
fiber stress corresponding to these test pressures does not exceed
half of the minimum specified yield strength of the titanium tube,
as determined by the equation given in 16.1. If one and a half
times the working pressure exceeds 2800 psi (19.3 MPa), the
hydrostatic test pressure should be agreed upon between the
manufacturer and the purchaser.
