U型密封元件
Type U of sealing components
Performance and Purpose:
It makes use of the advantage of Polyurethane，such as high strength, hardness，good elasticity and high-wearing feature. The type U of sealing component is used in the hydraulic testing of oil well casing tube，steel pipe and a variety of welded steel pipes of the Petroleum and Natural Gas Industry.
利用聚氨酯材料强度高、硬度大、弹性好、高耐磨等综合性能突出的特点，所制造的密封圈用于石油天然气工业——油气井套管、油管及各种焊接钢管的耐压试验。
Advantage
- The outer wall or inner wall of steel pipe can be sealed according to the situation.
可根据情况密封钢管外壁或者钢管内壁
- The sealing structure is simple than the other sealing rings.
密封试压结构简单
Working conditions:
According with several standards about hydraulic testing requirements：such as API 5CT/ISO11960:2011, GB/T9711.1-2011, GB/T9711.2-2011，etc. for Petroleum and natural gas industries—Steel pipes for casing or tubing; GB8163 - 2008 for seamless steel tubes; GB/T3092-2008 for welded steel pipes.
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。
