1 Superior Material
QianCheng-QCCO plan starts with sophisticated metallurgy and clean BOF steelmaking techniques. Continuous throwing followed by very hot-moving, generates warm-rolled strip of optimum higher-top quality for tube generating.
2 High Dimensional Accuracy
High uniform wall thickness and smooth finish deliver casing and tubing with a superior degree of high-quality and fantastic driftability also as higher performance properties.
3 Hard Weld
Sound welded portion as hard as the base metal results from QianCheng-QCCO’s newly- developed technology.
