Permissible Variations in Dimensions
Diameter-Variations in outside diameter shall not exceed those prescribed in Table 4.
Thickness-The variation in thickness at any point shall not be more than ±12.5 % of the nominal wall thickness specified.
Length-Pipe shall be furnished in lengths as specified in the purchase order. No pipe shall be under the specified length and not more than 1 ⁄ 4 in. (6.4 mm) over that specified.
Straightness-The pipe shall be free of kinks and bends and the maximum bow of lengths up to 10 ft (3 m) shall not exceed 1:500. For lengths greater than 10 ft, the maximum bow shall not exceed 1:400.

Finish
The finished pipe shall have smooth ends, be free of burrs, and shall be free of injurious external and internal imperfections of a nature that will interfere with the purpose.
 

Testings
Bending Test
Pipe 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.
 
Flattening Test
Seamless pipe 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)
e = 0.04 through 1 in. pipe size, and
e = 0.06 over 1 in. pipe size.
For ASTM B861 Grade 12 Titanium Alloy Seamless Pipe not shown above, the requirements for the flattening test shall be negotiated between the manufacturer and purchaser.
 
Hydrostatic Test
Each length of pipe shall withstand, without showing bulges, leaks, or other defects, an internal hydrostatic pressure that will produce in the pipe wall a stress of 50 % of the minimum specified yield strength at room temperature. This pressure shall be determined by the equation:

 

where:
P = minimum hydrostatic test pressure, psi (or MPa),
S = allowable fiber stress of one-half the minimum yield strength, psi (or MPa),
t = wall thickness, in. (or mm),
R o = outside tube radius, in. (or mm), and
E = 1.0 seamless pipe.
 
The maximum hydrostatic test pressure shall not exceed 2500 psi (17.2 MPa) for sizes 3 in. (76 mm) and under, or 2800 psi (19.3 MPa) for sizes over 3 in. (76 mm). Hydrostatic pressure shall be maintained for not less than 5 s.
 

Terminology
lot, n-a number ofpieces ofpipe ofthe same nominal size and wall thickness manufactured by the same process from a single heat of titanium or titanium alloy and heat treated by the same furnace parameters in the same furnace.
seamless pipe, n-a hollow tubular product produced with a continuous periphery in all stages of manufacture.
