People use the words pipe and tube interchangeably, and they think that both are the same. However, there are significant differences between pipe and tube.

The short answer is: A PIPE is a round tubular to distribute fluids and gases, designated by a nominal pipe size (NPS or DN) that represents a rough indication of the pipe conveyance capacity;

A TUBE is a round, rectangular, squared or oval hollow section measured by outside diameter (OD) and wall thickness (WT), expressed in inches or millimeters.

What is Pipe?

Pipe is a hollow section with round cross section for the conveyance of products. The products include fluids, gas, and connected with pipe fittings and flanges.

The most important dimensions for a pipe is the outer diameter (OD) together with the wall thickness (WT). OD minus 2 times WT (SCHEDULE) determine the inside diameter (ID) of a pipe, which determines the liquid capacity of the pipe.

We –Xian Fexda can offer the good quality Titanium smls Pipe/Tube with below grades & standards.

Grade: GR.1, GR.2, Gr.3, Gr.7,GR.9, Gr.12

Standard: ASTM B338, ASME SB338, ASTM B861, ASME SB861

OD: 3.175-219 mm x W.T.: 0.4-12.7 mm x Length: 16000 mm max

What is Tube?

The name TUBE refers to round, square, rectangular and oval hollow sections that are used for pressure equipment, for mechanical applications, and for instrumentation systems.

Tubes are indicated with outer diameter and wall thickness, in inches or in millimeters.

Tubes can be used in heat exchangers, boilers and refrigeration units, as well as instrumentation, medical, mechanical and pressure applications.

If the smls tube OD< 60.3 mm, the finished tubes will do the Flattening Test, Bend Test( only tube OD<50 MM needs do bend test), Flaring Test, UT, Hydrostatic Test and Pneumatic Test before order shipping.

If the smls tube OD> 60.3 mm, the finished tubes will do the Flattening Test, Flaring Test, Pneumatic Test before order shipping.

The material grade and standard of titanium pipes/tubes that we- Xian Fexda could offer as below:
