Joint details
1. Welded joint
It is the most widely used type for the joining of weldedsteel pipe. Steel pipe is relieved with beveled ends which are made withspecial equipment in compliance with the relevant standards.
2. Spherical socket joint
It provides the possibility of a rotation 10 degreesat the pipeline without the utilization of any special fittings. Steel pipesare welded from outside after proper erectioningaccording to required angle.
3. Spigot and socket joint
Especially used for the steel pipes inside coated withcement mortar. Steel pipes are welded from outside after erectioning.
4. Flanged joint
The special manufactured flanged are welded to theends of the pipe and then jointed with bolts.
