Precision ERW pipe

We apply high frequency welding and online ID scarfing technology to produce precision ERW tube. The residual height of ID scarf is within +0.05/-0. 10, which enables to be used for shock absorber cylinder, reserver, supporing bar, steering column and other auto parts application. Meanwhile shrinking and drift expansion are feasible with the max deformation achieves 45% The good appearance, which is not available for seamless tubes and ordinary ERW tube.
