详细介绍

Type NM of internal expanding sealing components

Performance and Purpose:

It is made up of sealing ringfan-shaped supporting blocks and fan-shaped angles. It is mainly used in the pressure test of steel pipe by hydrostatic testing machine. As it is designed to test steel pipe from its inner diameter, when testing, the sealing ring will expand to enclose the pipe inner diameter to achieve the purpose of sealing. Its test head is smaller than type D or C and production cost is lower as well. It is applicable to the pressure testing of casing, tubing, natural gas pipe and other steel pipe.

NM型内胀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。由于NM型内胀密封元件是从钢管的内径对钢管进行密封试验,试压时密封圈向外侧膨胀与管内壁接触并密封,故其试压头比D型或C型小巧,制造成本低。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。

Advantage

  1. Lip Optimization: under peripheral pressure, the lip and groove surface fit more closely, and the higher the pressure, the better the lip sealing.

唇边优化,在外周受压下,是唇边与沟槽面贴合更紧密,压力越大唇边密封越好

  1. The fan-shaped supporters , in the premise of increasing the strength of the sealing ring, can shrink and expand in radial direction with the sealing ring.

    专业设计扇形支撑块,在增加密封圈强度的前提下,能随密封圈在径向方向收缩、胀大

Working conditions:

According with several standards about hydraulic testing requirementssuch 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/ISO11960:2011GB/T9711.1-2011GB/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。
