The second letter denotes the type of seal face: single-ended (S); double seal without pressure (also known as "tandem seal" in the seventh edition) (T); or double seal with pressure (also known as "d

The V-shaped protrusion in the middle part of the metal strip functions like a spring, providing excellent rebound to the gasket when operating conditions change. Different materials can be selected f

304 spiral wound gaskets can be widely used in the petrochemical industry. In many equipment, high-temperature and high-pressure gases or liquids are used, which requires the use of high-performance s

The 304 spiral wound gasket is a commonly used sealing component known for its heat resistance, pressure resistance, acid and alkali resistance, corrosion resistance, and other advantages. It is widel

Metal spiral wound gaskets with excellent resilience can automatically adjust to the working pressure, thermal cycles, and vibrations of piping systems. They are particularly suitable for places with

Graphite gaskets are cut or stamped from pure graphite plates or graphite plates reinforced with metal (toothed plates, flat plates, meshes). They exhibit numerous excellent sealing properties such as

Metal spiral wound gaskets are semi-metallic materials processed from various materials. As an important sealing product, they have been widely used. Secondly, the surface of the product should not

Metallic gaskets (rings) come in shapes such as trapezoidal, oval, prismatic, triangular, and serrated. They are suitable for sealing flammable, explosive, high-temperature, and high-pressure media, o

Metal spiral wound gaskets utilize alloy or stainless steel strips as the base material, with graphite, asbestos, or PTFE as the filler material, arranged in an alternating spiral winding pattern in "

, corrosion resistance, high-pressure resistance, radiation resistance, and heat transfer. This material is woven from low-sulfur expanded graphite yarn and lined with cotton yarn to enhance its stren

Oval metal toothed gasket as a kind of ring gasket, in the use of precision mold has a very important role, the process of its purchase, which must pay attention to.

(2) During installation, the processed sealing groove was not inspected. The groove had unchamfered edges, roughness, dimensional accuracy, and dimensional tolerances that did not meet requirements.

Unscientific Design and Selection of D-type Metal Spiral Wound Gasket Seals (1) Seals are classified into static seals and dynamic seals based on whether there is relative speed between the sealing ma

Currently, with the rapid development of the market economy and the innovative advancements in production processes and equipment, there are an increasing number of domestic metal spiral wound gasket

The oval metal ring gasket is characterized by its low cost and ease of installation, making it suitable for locations that require frequent assembly and disassembly. However, the clamping force of sp

Irregular-shaped metal spiral wound gaskets can distribute the load of nuts and have shock absorption and damage reduction properties. They play a role in ensuring stable tightening during the operati

Regarding oil-free black PTFE packing, it reduces material consumption and increases service life. Packing seals are designed to allow a certain degree of leakage. Therefore, packing rings cannot meet

They are a series of asbestos-free sealing gaskets made of organic fibers such as aramid and plant fibers, nitrile rubber, and mineral materials. Since the asbestos-free gasket series not only has hig

Under lower preload forces, the serrated combination gasket is the first choice. The soft sealing layer on its surface prevents direct metal-to-metal contact, ensuring a firm and tight separation that

asic type of metal spiral wound gasket is made by winding metal strips together with other strips of graphite fiber and Teflon fiber. Due to its special manufacturing process, it is known as a gasket
