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.Test:Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties ( Bending Test, Blow Test, Impact Test), ExteriorSize Inspection, Hydrostatic Test, X-ray Test.Mill Test Certificate:EN 10204/3.1BThird party inspection:SGS, BV, Lloyds etc.
