2000's
1900's
NEXTEEL Co.,Ltd., an ERW pipemanufacturer, is equipped with the state of art facilities and produces API 5CT casing & tubing and API 5L line pipe for energy development of oil and gas.NEXTEEL has a capability of producing up to 596,000 MT of steel pipe, casing & tubing a year, from 1.050 inches thru 16 inches of pipe with high quality hot coil supplied from POSCO.
NEXTEEL Q&T specializes in heat-treated steel products. It makes API 5CT casing & tubing-pipe and API line-pipe for oil & gas development industry by heat-treating them with state-of-the-art facility. The products are being sold globally.NEXTEEL Q&T can heat-treat 120,000 MT of pipe every year. It uses the best quality raw material from POSCO and supplies pipes with diameter in the range of 4.500” ~ 9.625”.
The opening of its Houston operation office will be the first of many important changes for NEXTEEL in recent years relating to market environments and how the company is responding to them.And also it will be a great step towards being realized as the best partner for the global oil and gas development industry.

Philosophy of NEXTEEL
01 COMPANY
Loyalty is to willingly lend a helping hand to others when asked, no matter what adversity one may be undergoing. When one is well off, it is not hard to help others; however, when one is in difficulty, it is difficult to help others. Treating others as we would like to be treated is our philosophy.
Loyalty01
Conviction is to pursue and realize one's belief. While everyone is free to hold his or her own belief, it is very difficult to remain faithful to one's belief under unfavorable circumstance, not to mention to realize it. History is made by those who have strong conviction and work hard to realize it.
Conviction02
While we love trustworthy people, it is important to remember that we should be trustworthy first. We should not promise too many things to others, but once we made a promise, we should do our best until the promise is fulfilled no matter how trivial it may be.
Trust03
Inspection & Equipmentsdvanced On-Line UT
- With Phase Array type on-line UT, real-time inspection on both weld seam and inside weld bead could be possible. - As it is adjustable to change of seam position, inspection area of weld seam is expanded more than other types.- Real time line control upon operator’s judgment is possible when quality troubles occur.
dvanced Off-Line UT- Weld Seam : Phase Array Multi-Channel(10 channel) type can improve inspection accuracy and reliability.- Base Metal of Pipe Body : Full Body UT inspection on both based metal and weld seam is performed with Rotary UT which is superior to ET(Eddy-Current Test) or Magnetic flux leakage.
ydrostatic tester- Capacity up to 7,260 psi(511bars) with 3 heads. - Improve production efficiency and inspection reliability.
omplete Test Equipments Line upUtmost quality assurance with all necessary test equipments line up.- Universal tension testing machine, chemical composition analysis machine, metallurgical microscope. - Salt spray tester, hardness tester, impact tester and specimen cutting machine and so on.
Sour Gas Test room.- Universal tension testing machine, chemical composition analysis machine, metallurgical microscope. - HIC(Hydrogen Induced Cracking)/SSCC(Sulfides Stress Corrosion Cracking) tester, DWTT(Drop Weight Tear Tester).

NEXTEEL’s Culture Quick decision making- Simple Communication Steps▶ Speed Management.- Continuous investment for R&D and recruitment of professionals.
CEO has strong initiative & Insight of Market Trend- 2006 - 16 inch pipe line & 8 inch pipe line in NEXTEEL #1 API Mill.- 2010 - 4 inch pipe line in NEXTEEL #2 API Mill.- 2012 - Quenching & Tempering Facility in NEXTEEL QNT.
Operating R & D Center - Internally R&D by capable engineers from each department.- Collaboration with POSCO Research Institute, POSTECH, RIST(Research Institute of Industrial Science & Technology), POMIA (Pohang Institute of Metal Industry Advancement).
- Collaboration with related companies like TaeWoong (Equipment) and DongYong Tool (Seam Remover) to improve process technology.
1
Improvement on reliability of welding seam of NEXTEEL’s PipeDevelopment of welding technology and equipment- Adoption of multi-step forming stand to minimize forming stress.- The Longest air cooling zone after PSA (Post Seam Annealer)
Improvement on accuracy of NDT equipment Using high quality raw materials to minimize segregation and non-metallic inclusion in base metal- Nexteel has been procuring all raw material for API Grade from POSCO.
3
Prospects of NEXTEEL’s ERW ProductsHigh productivity and low production costExcellent in uniformity of material quality of pipe bodyExcellent in uniformity of wall thickness- Uniformity of Cross-Sectional Area of the Inner Diameter is good for transportation of fluid.
Easy control on various product length- Save cost and time with less joint.- NEXTEEL can produce up to 60ft length pipes currently, and has plan to develop “Coiled pipe” for 8 inch OD and smaller which may provide comparably unlimited length of pipe.
2
Further Developing Direction High T/D (Thickness / Diameter) Ratio - Replace applications for seamless pipes.
Direct welding higher strength base metal (P110 as rolled)- Get higher grade pipes without heat treatment process
