This is a critical service which poses a large safety risk to the facility and requires very careful selection of materials and extreme cleanliness standards. After the incident the customer initiated the process of re-evaluating the materials, including sealing products, that they were utilizing in this extremely critical

Carbon

Carbon-graphite materials are also widely used as rotating shaft and face seal materials, figure 2. They perform well when running against metal and ceramic counterfaces. Seals are manufactured from solid rings, split rings and segmented rings for use in both liquid and dry-running applications in the aerospace, nuclear, petrochemical and general marine industries.

PTFE

ET013 is utilized in reciprocating applications where high pressure-velocities are present and makes a good choice for buffer ring seals and other pressure knock-down devices. When used in conjunction with one of the available Eclipse spring energizers, this material makes an excellent high temperature seal as well as an aggressive scraper up to temperatures of 575F (302C).

Valve stem seal selection criteria

Temperature pressure As per API RP 615, 3 high-temperature service is typically defined as a service with a temperature higher than 205 C (400 F) for soft-seated valves and 400 C (750 F) for metal-seated valves. Low-temperature service is generally defined in the

O

General Engineering Menu | O-Rings Suppliers Molded O-Rings Services O-Rings Design Guidelines, Specifications, Materials An O-ring, also known as a packing, is a flexible gasket in the shape of a loop; it is a elastomer with a round cross-section designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.

High Temperature Gasket Material

Topgraph 2000 combines compressed synthetic fibres with graphite to create a high quality gasket sheet that is more flexible and far more stable than other graphite based materials. It is easily able to handle temperatures of up to 350C and can even resist temperatures of up to 500C depending on media and pressure.

PTFE seal, PTFE gasket

Temperature limit: -30 C - 105 C Pressure limit: 0 bar - 400 bar Diameter: 50 mm - 360 mm K19 is a four piece double acting heavy duty compact seal which consists of one PTFE bronze profile ring, one elastomeric nitrile rubber pre-load sealing element and two thermoplastic back-up rings.

Carbon Graphite Mechanical Seal Types

Each Seal has a stator which is sealed to the pump or mixer housing via an O-ring and a rotor which is sealed against the shaft via another O-ring. Both the rotor and stator have a surface which has been polished to typically 2 to 3 Light Bands flat (0.6 to 0.9 m).

Rod Seals

The Bronze filled PTFE inner seal ring, when in contact with the Piston rod, ensures a stick slip free movement and reduces the friction to a minimum. The filler increases the strength in the seal ring to prevent it from extruding and can withstand pressure as high as 400 BAR.

What's High pressure self

2020/5/22The high pressure self -tightening flange is composed of segment clamp, butt weld hub, sealing ring and bolt. Compared with the conventional soft sealing flange, that is, plastic deformation of the gasket to achieve the seal, the high-pressure self-tightening flange depends on the hub of the seal ring (T-Arm) elastic deformation to seal, that is, the metal to metal seal.

Types of Gaskets for Flanges (Soft, Spiral, Ring Joint)

Learn about the 5 key flange gaskets types (used in the oil and gas industry): non-asbestos gaskets full and raised face (used for low-pressure, low-temperature and non-critical applications), spiral wound gaskets (for higher temperature and pressure oil and gas applications), Ring joint gaskets style R, RX, BX (for RTJ flange faces), Kammprofile and Jacketed gaskets.

Cartridge Seal

The seal cartridge requires a similar axial space as a single ring dry gas seal, but a separation seal is not required for this application, which reduces bearing span. A seal buffer gas is used to isolate the oil seals from the process, and can be fed off the discharge of the compressor similar to a dry gas seal

PRESSURE SEAL BONNET DESIGN

Pipeline Valve gate, globe and check valves are available with pressure seal bonnets in 900 to 2500 class. The pressure seal design is superior to the bolted design. With the bolted body design, as pressure increases the gasket sealing force reduces, allowing the

The Backing Ring. Sound Sealing Sense!

Graphite is compressible so it consumes more space on the bonnet neck than a metal seal. Our task is to design a VSG and backing-ring that can stand up to pressurization, while still allowing for assembly." So, the next time you order a VSG pressure seal
