C型超高压超大间隙密封元件
一、性能和用途
C型超高压超大间隙密封元件是由密封圈、扇形支撑块和支撑角组成的密封元件。主要用于水压试验机对钢管的耐压试验。C型密封元件具有比D型（详见本公司前期样本）更大的密封间隙，同种规格的密封圈可适用的钢管规格范围更广泛。本产品适用于水压试验机对套管、油管、天然气输送等钢管进行水压试验，也可用于钢管、管接头、焊口检漏及超高压阀门密封等。
二、工况条件
符合API 5CT/ISO11960:2011、GB/T9711.1-2011、GB/T9711.2-2011等石油天然气工业——油气井套管或油管用钢管；GB8163-2008无缝钢管；GB/T3092-2008焊接钢管等标准水压试验条件。
工作压力：≤120 MPa
工作温度：-20℃～+80℃
工作介质：水、乳化液、液压油
三、材质
聚氨酯
四、设计标准
参照GB/T3672.1-2002公差。
