We are a professional supplier for welded pipes and tubes, all grades and dimensions to the oil and gas, petrochemical, Chemical and Power industries.
We can supply all kinds of welded pipes (ERW, LSAW, SSAW), we have a huge range of different welded pipes constantly on stock.
ERW (Electric Resistance Welded):
ERW Steel Pipe-Electric Resistance Welded Steel Pipe is made of hot-rolled steel coils/sheets that have been put in a process known as cold roll forming. The obvious advantage of ERW steel pipe compared to seamless steel pipe is the uniform wall thickness. According to API standard or GB/T9711.1 standard, both ends of the steel pipe are beveled and length can be fixed as required
| Application: |
| Low Pressure Fluid (water, oil, gas and other liquid) transmission Stress & pressure structural parts and spare parts |
| Standard & Steel grade: |
| Line Pipe: API 5L PSL1/PSL2,GR.B-X70,GB/T 9711-1,GB/T9711-2,ISO 3138-1,ISO 3192-2 |
| Structural Pipe: ASTM A53 GR.A/B/C,EN 10219,EN 10217,JIS G3444,AS 1163 |
LSAW (Longitudinal Submerged Arc-Welded):
LSAW Steel Pipe refers to Longitudinal Submerged-Arc Welded Steel Pipe, which is made of hot-rolled steel plate or coils, LSAW steel pipe always goes to the big-sized welded pipe, which can’t be manufactured by electric resistance welding technique (ERW)
| Application: |
| Low Pressure Fluid (water, oil, gas and other liquid) transmission Stress Structural support in industrial construction (bridge building, pile driving, billboard support ,…etc) |

SSAW (Spiral Submerged Arc- Welded):
Spiral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral.
SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature.
| Application: |
| These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction |
