"BEIJING JIANKE HUIFENG SCIENCE & TECHNOLOGY CO., LTD." (Registered trade mark: © and # >C >%® ) Is a science and technology manufacturer, specialized in developing, producing and selling the ultrahigh pressure sealing components for steel pipe hydrostatic testing machine. Since 1992, we have been concentrating on the development and manufacturing of sealing components for hydrostatic testing machine. And we have the strong professional research development team and excellent after-sales service team. The products have been awarded many national patents [Patent No.: 012198439, ZL02 2 94523.7, ZL2011 02 0243967.4) and the products meet hydrostatic testing requirements : such as the standard of API Spec 5CT/IS011960:2011 for ^Petroleum and natural gas industries—Steel pipes for use as casing or tubing for wells* . The products are famous for its stable and durable performance and wildly used in domestic and Southeast Asian countries. Moreover, it is listed as Class A vendor by "Tianjin Pipe (Group) Corporation” . Many years the Company has accumulated experience of sealing ring for hydrostatic testing machine both at home and abroad, base on original big gap sealing component, type U, type PY and end-face sealing, etc. key focus on increasing the combined sealing ring, sealing ring for booster cylinder and some of commonly sealing structure used by foreign hydrostatic testing machine designer. It makes the company's products continuously to be improved and updated, and the customer can more easily choose what they need from the company's products to meet their demand greatly. The company also established a long-term partner relationship with more than ten major hydrostatic testing machine designing company and units to develop and produce many kinds of sealing products to meet their equipment. The company's “Quality target” is: to meet customer's demand and achieve win-win with superior quality, high efficiency, and continuous improvement. In 2002, the company got approval of ISO 9001:2000(GB/T19001-2008/IS09001:2008) with registered No.: 04312Q20554R2S.

C 型超高压超大间隙密封元件 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

Type C of large gap ultrahigh-pressure sealing components Performance and Purpose: It is made up of sealing ring^fan-shaped supporting blocks and fan-shaped angles. It is mainly used in the pressure test of steel pipe by hydrostatic testing machine. Type C has more seal gap than Type D (refer to company’s former catalogue), the sealing components with same dimensions are applicable to a wider range of steel pipe gage. It is applicable to the pressure testing of casing, tubing, natural gas pipe and other steel pipe. It has also been used in leak test of the steel pipe,welded joints and...

NM 型内胀密封元件 性能和用途 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

Type NM of internal expanding sealing components Performance and Purpose: It is made up of sealing ringN fan-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...
