Mining

GNEE's S355J2H precision seamless steel pipe is usually produced using a cold rolling process, which helps improve its precision and reduce losses during machining.

Square tube is formed from coil and then ran through a series of dies. It’s welded from the inside to form its shape. Square tubes are generally used for maintenance and structural purposes.

ASTM A403 WP304 seamless elbow is often used in pipeline systems that require high corrosion resistance and pressure-bearing capacity, such as chemical, petroleum, natural gas, food processing and other industries.

The production process of DIN 1629 steel pipe supplied by GNEE includes heating of pipe billet, piercing, three-roller cross rolling or continuous rolling, tube stripping, sizing (or reducing), cooling, straightening, hydrostatic test (or flaw detection), marking and warehousing.
