Joints

Types of pipeline-end:

Bevelled: for butt weld. (Welded Joint).
Cylindrically expanded at one end: Spigot & Socket Joint that facilitates overlapping and welding.
Spherically expanded on both ends: joint system (Spherical Joint) that facilitates the assembly and welding overlap, allowing, in addition, a greater angle of deflection (up to 8º).
