特殊通径用套管的生产

The production of petroleum casing used special drift testing

根据天津钢管公司长圆扣P110级石油套管的生产合同要求 ,生产中存在套管特殊通径、单重保证等技术难点 ,为此设计了技术指标。经校验 。

The difficult technologies of producing p110 petroleum casing, such as special drift testing because of the small gap between casing inner-diameter and the drift, unit weight assurance, etc., are analyzed and the technologies indexes are designed based on contract requirment. The practice has proved that the casing quality can meet the need of contract.
