Quality Tests for Titanium and Titanium Alloy Tubes:

Inspections and tests ensure that materials meet international standard specifications including ASME SB338,

ASTM B338 or 337 in addition to our customers’ specific requirements. Third party inspections

(TUEV, SGS, LR, MOODY, ITS, DNV) and customer inspections are welcomed.

USTi provides the following testing for Ti seamless and welded tubes:

Chemical	Composition	Ultrasonic Testing	Elongation
Visual Inspection	Eddy	Current Testing	Flattening
Pneumatic Test	Hydrostatic	Dimensional	Inspect
Tensile	Yield	Hardness	Flaring

Titanium Welded Tube:

Titanium Welded Tube, Pipe

ASME SB338, ASME SB862

GR1, GR2, GR7, GR12

OD: (0.315”-48”) WT: (0.0197”-0.5”)

Length: at random length

Titanium welded tubes are processed from titanium coil and longitudinally welded by TIG process without metal filler

so it guarantees the homogeneity of the welded area. Moreover, due to features such as evenness of wall thickness,

each tube has the same mechanical properties as the initial coils.

More equipment manufacturers prefer titanium welded tubes rather than seamless for their projects.
