histeel-chart2-283x300HiSteel – Pipe Line

Athanor’s team has been privileged to successfully supply high quality DSAW pipe to major oil and gas transmission projects in the USA and abroad.

We are enthused to continue such endeavors by offering to the US market and foreign projects HISTEEL pipe. Indeed, with a new state-of-the-art plant in South Korea, HISTEEL prides itself in manufacturing the highest quality API5L DSAW longitudinal weld large diameter and heavy wall thickness pipe.

HISTEEL Production Line

A competent, well-trained staff enables Athanor Steel to give each customer and project full logistical support during every phase.

3-roll-bender3-Roll Bender

  • Can produce max 1.260″ (32mm) for API5L X-80 & 1.575″ (40mm) for API5LB
  • The high bending force and precision roll design secures easy forming of both thin and thick plate
  • Auto positioning & CNC control

cold-expanderFull Length Cold Expander

  • Full length cold expander reduces residual stress between body and weld, improving anti-corrosion, anti-cracking, and steel longevity
  • Full length cold expander detects eventual hairline cracks and defects

Hydrostatic Testing

  • All pipe hydro tested to specified API pressures

ultrasonic-testUltrasonic Test

  • The ultrasonic test improves detection of eventual defects: Detects eventual longitudinal and transversal weld defects, as well as eventual lamination defects and HAZ
  • Meets the most stringent quality control standards of all major oil and gas companies

radiographic-testRadio Graphic Tests

  • Application of both UST and X-Ray tests guarantees the soundness of the weld seam
  • The SEIFERT ISOVOLT 320KV, which provides improved permeability and resolution, can efficiently find eventual defects in heavy wall thickness
  • The radiographic test is able to read eventual defects in real time with the high resolution image intensifier
