Tube and Pipe Fabrication

The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

Tube-bend tooling: square-back wiper dies or wiper inserts?

November 8, 2005

By:

Wiper dies are a fundamental requirement in modern tube bending applications in which tubes are bent at increasingly tight bend radii with increasingly thinner wall thicknesses. The design of the wiper die plays a key role in its performance and durability, as does its manufacturing method and the material from which it has been constructed.

Improving welded joint structure, properties in oil and gas pipelines

October 12, 2005

By:

The welding process and ambient temperature affect the structure and mechanical properties of welded joints in large-diameter (1,420 mm) pipes of manganese low-alloy steels, which are used commonly in oil and gas pipelines. Pulsed welding can improve the homogeneity of the structure and reduce the grain size of metal of the weld and HAZ zones. The ambient temperature causes structural changes, which affect the ductility and impact toughness in the welded joint zones. Temperature plays a role. Research shows that welding at 20 degrees C leads to an increase in ductility and impact toughness of 8 percent to 27 percent, and welding at -60 degrees C leads to an increase of 15 percent to 24 percent.
