Product Description

ASME B16.20 1500LB DN25/DN50/DN80/DN100/DN200/DN150/DN250 Inch Ring Joint Gasket

This type of gasket is commonly used in the oil and gas industry, chemical processing plants, and other industries where reliable seals are required to prevent leaks.

The 5Gr1/2Mo material is a low-alloy steel that is commonly used in high-temperature and high-pressure applications. It is known for its high strength and excellent resistance to corrosion and oxidation. The ASME B16.20 standard specifies the dimensions, materials, and design of ring joint gaskets, including those made from 5Gr1/2Mo material.

The 1500LB rating of this ring joint gasket refers to the maximum pressure that the gasket can withstand. This gasket is designed to seal flanged joints that are subjected to high-pressure and high-temperature conditions, making it suitable for use in applications such as pipelines, valves, and pressure vessels.

The ring joint gasket is designed to fit into a machined groove on the flange, providing a tight seal when compressed. The shape of the gasket is designed to be compatible with the shape of the groove to ensure a proper fit. The gasket is made up of two parts: the metal ring and the sealing element.

The metal ring is typically made of 5Gr1/2Mo material, which is machined to the required shape and size. The sealing element is usually made of a softer material, such as graphite, which is placed inside the groove on the metal ring. When compressed, the sealing element is forced against the flange faces, creating a tight seal.

Proper installation of the ring joint gasket is critical to ensure a reliable seal. The gasket must be installed in the correct groove and compressed evenly to achieve an effective seal. Over-compression can damage the gasket, while under-compression can result in leaks.

In conclusion, ASME B16.20 1500LB DN25, DN50, DN80, DN100, DN200, DN150, DN250 Inch Ring Joint Gasket is a specialized gasket designed for high-pressure and high-temperature applications. The use of 5Gr1/2Mo material provides excellent resistance to corrosion and high-temperature conditions. Proper installation and selection of the appropriate gasket size and material are critical to ensure a reliable seal.

Please consult a Hi-Tech Gasket representative.

 

R series

R Series ring type joint gaskets are available in oval and octagonal designs. The oval design can be used in older round bottom gland designs, while both can be used in a flat bottom design. R Series are available up to 5,000 PSI.

 

 

RX Series

RX series are replaceable with R series octagonal gaskets designed for API 6B flanges. RX out perform R series in situations that have higher pressures with more intense vibrations. RX gaskets are available up to 5,000 PSI.

IX Seal Rings are designed and used where NORSOK CFC (Compact Flange Connections) are in use. The rings come in three different kinds of steel and are coated with PTFE in varying colors in order to distinguish between them

The designed or materials shall be selected, so that main sealing ares can not be subject to corrosion.
How IX Ring Seal Works?

IX Seal Ring axial forces are exerted on the taper of the metal seal ring and translated into a radial sealing force.

Furthermore with increased pre-load, the bevel is closed and face to face contact is achieved at the outer wedge while most of the bolt pre-load is transferred as compressive forces between the flange faces at the heel.

There are two independent seals. The first seal is created by application of seal seating stress at the flange heel. The flange also remains in contact along it`s outer circumference at the flange faces for all allowable load levels. The main seal is the IX Seal Ring. The seal ring force is provided by the elastic stored energy in the stressed seal ring. Any hell leakage will give intemal pressure acting on the seal ring inside intensifying the sealing action.

The design aims at preventing exposure to oxygen and other corrosive agents. Thus, this prevents corrosion of the flange faces, the stressed length of the bolts and the seal ring.


Application of ring joint gaskets

Usually used in high temperature and high pressure steam, gas, solvent tube flange, tank, pressure vessel, the joint surface, high temperature and high pressure valve, the cover.Oil and gas industry in wellhead sealing and oil extraction tree.
