Joint details: |
|
|
|
|
|
|
|
Welded joint: The most widely used type for the joining of steel pipes. Steel pipe is relieved with bevelled ends which are made with special equipment in compliance with the relevant stanards. |
|
|
Spherical socket joint: provides the possibility of a rotation 10 degrees at the pipeline without the utilization of any special fittings. Steel pipes are welded from outside after proper erectioning according to required angle. |
|
|
Spigot and socket joint: Wspecially used for the steel pipes inside coated with cement mortar. Steel pipes are welded from outside after erectioning. |
|
|
Flanged joint: The special manufactured flanged are welded to the ends of the pipe and then jointed with bolts. |
