EN10210 S355J2H ERW Black Steel Pipe use for contruction
ERW steel pipes are manufactured by low-frequency or high-frequency
resistance "resistance". They are round pipes welded from steel
plates with longitudinal welds. It is used to transport oil,
natural gas and other vapor-liquid objects, and can meet various
requirements of high and low pressure. At present, it occupies a
pivotal position in the field of transportation pipes in the world.
The EN10219 S355J2H Black ERW welded pipe shall have a smooth surface corresponding to the manufacturing method used; bumps, cavities or shallow longitudinal grooves resulting from the manufacturing process are permissible, provided the remaining thickness is within tolerance.
Surface defects may be removed by the manufacturer by grinding, provided that the thickness of the hollow section after the repair is not less than the minimum permissible thickness in accordance with EN 10219-2.
The ends of the EN10219 S355J2H Black ERW Welded Pipe shall be cut nominally square to the axis of the product.
For both non-alloy and fine grain EN10219 S355J2H Black ERW Welded Pipe, repair of the weld shall be permitted.
For non-alloy hollow sections, repair of the body of EN10219 S355J2H Black ERW Welded Pipe by welding shall be permitted unless otherwise specified.
The conditions under which, and the extent to which, welding repair to the body of EN10219 S355J2H Black ERW Welded Pipe may be carried out shall be agreed between the manufacturer and the purchaser.
During ERW pipe welding, heat is generated when current flows through the contact surface of the welding area. It heats the two edges of the steel to the point where one edge can form a bond. At the same time, under the action of the combined pressure, the edges of the tube blank melt and squeeze together.
