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...
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...
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...
Hammer Union Seals are one-way / high-pressure / static seals, which are used in hammer union-style pipe connections to establish flow lines and prevent leakage. JST provides a number of compounds compatible with mud, crude oil and chemicals with acid or H2S in the oil & gas industry, in steel mills, chemical plants, strip mining, and marine dredging. Seal material is chosen as per application...
Structure of casing head The wellhead casing is composed of four-way, casing hanger, jacking assembly, flange type parallel gate valve, connector, pressure display mechanism, etc; Metal and rubber seal of wellhead casing The metal and rubber seals of the casing head are composed of the wellhead casing body, BT rubber seal, upper metal seal component, lower metal seal component, casing hanger, dove...
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...
Application of Fluorinated Rubber in Oilfield Oil field is an extremely harsh environment for rubber materials. Due to the high temperature and chemical mixture in the oil field, it is required that the rubber used can resist the harsh environment and provide safe and reliable services. Viton can be used in this harsh environment. The products made of fluororubber for oil field and petrochemical i...
Rapid gas decompression (RGD) resistance is an extremely important property of elastomers in the oil and gas industry. Rapid gas decompression (RGD) often occurs when high pressure gas molecules are transferred to the elastomer under compression. When the pressure around the elastomer is suddenly released, the compressed gas in the elastomer will expand and leave the elastomer, causing RGD. When t...
