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.
