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

1. 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

2. The sealing structure is simple than the other sealing rings.

    密封试压结构简单

Working conditions:
