The 26" line at QCCO Functions produces ERW pipes having the largest outer diameter inside the globe. With the manufacture of linepipe applying this feature as a single of its sturdy points, QCCO Steel has commercialized extra-heavy wall ERW linepipes and conductor casings as substitutes for the traditional UOE products. To realize the exact same strength, toughness, and weldability as in UOE pipe, in these goods, the composition design and style on the hot rolled steel sheet used in the ERW pipe was optimized plus the cooling capacity with the hot rolling line was strengthened.

In parallel with this, Chita Operates also strengthened the steel pipe manufacturing capacity from the 26?± ERW steel pipe mill, developed an oxide control method and weld seam heat therapy technologies to improve the tough- ness of seam welds, and created a weld seam excellent assurance technology for heavy wall products.
