Specifications Welding seam online annealing widely used in petroleum
pipeline and other high quality steel pipe.
Steel pipe welding seam online annealing is an advanced
technology to produce high strength steel pipe, through welding
seam online annealing to eliminate residual stress of welding and
improve the organizational structure, making the welding seam and
it’s heat affected zone and has the same organizational structure,
toughness and strength performance as consistent with base
metal.
Induction annealing equipment of steel pipe takes the
induction heating coil as the main components for continuous
welding pipe machine, it heats the seam which has just been welded
and quenched, to above the critical temperature and anneals it
(seam) to avoid the potential crack .The fine-crystal-particle
structure produced by this process will guarantee a steel pipe
tenacious that meet all standard requirements of the
specification. |
