The seals made from carbon graphite materials have the common advantages of both metal and non-metallic materials. Its material characteristics includes excellent self lubrication, chemical stability, high thermal conductivity, high temperature resistance, corrosion resistance, high wear resistance, low expansion and easy maching. These characteristics of carbon graphite are necessary for pure wat...

Liner wiper plug is a tool for oil casing cementing operation. During cementing, cement slurry and mud are separated to prevent the cement slurry from infiltrating into mud and affecting the cementing quality. The liner wiper plug is designed to receive the drilling wiper plug and clean the liner casing after cementing. When locked in the landing ring, its front sealing ring provides an additional...
The downhole environment is much harsher and more complex than the surface environment, such as high temperature, high pressure, high corrosiveness, etc. Due to the structure and function of the downhole tools, they need to work for a long time in the well, so they must have good sealing ability. Traditional single seals have limitations in such a complex environment, while combination seals can s...
Main performance The section of Y-ring seal is Y-shaped, which is a typical lip seal. It can be divided into wide type, narrow type and Y type according to the different proportion of height and width of the section. According to whether the two lips are equal in height, they can be divided into Yx seal rings with equal height lips for shafts and holes, Y seal rings for rods and holes with unequal...
Hi There Before we discuss why does PTFE material play an important role in the sealing industry? Let me introduce you what is seals. Seals are used to prevent fluid or solid particles from leaking between adjacent bonding surfaces and the intrusion of external magazines such as dust, sediment, moisture and so on. It’s widely used in National defense, Chemical, oilfield, hydraulic, mining, Transpo...
Centralizer fin is a necessary tool for downhole oil production and plays a very important role in the field of oil drilling and production. The oilfield centralizer fin is mainly used to centralize the tubing in oil-water deviated wells to prevent the abrasion of tubing and casing wall caused by tubing creep during oil pumping and the cleaning of casing inner wall. Due to the complexity of well c...
Packer is one of the most common and essential tools in the process of oil recovery, water shutoff and water injection. It is used throughout the whole process of oil and gas exploration and development, especially in the well completion. The main part of the packer is the packer element, which is made of rubber with good elasticity. It is set in the annular space of casing and tubing by means of ...
