Metal winding gasket 0222 winding gasket

Metal winding gasket 0222 winding gasketMetal wrap pads are products that we often use in our daily lives. In a broad sense, metal wrap pads are made by winding metal and non-metal materials. Narrowly speaking, it refers to a circle made of metal material on the outside. It has a wide range of applications and also possesses metals of different types, properties, and structures. There are four types of structures for metal wrap pads, the basic type is suitable for mortise and tenon surfaces, and has good sealing performance. Internal ring type, suitable for concave and convex surfaces, with strong stress compensation capability. Equipped with a positioning ring, it can be used for flat or convex surfaces. The inner ring and positioning ring are also used for concave and convex surfaces and flat surfaces. For the installation of metal wrap pads, we must carefully read the instructions and not install them casually. The size of the winding part cannot be widened arbitrarily. Undoubtedly affecting the tightening of bolts. Basic gaskets must not be used on concave or convex surfaces, as this will cause gasket failure. Spiral wound gasket is an important sealing component widely used in industries such as petroleum, chemical, metallurgy, power generation, and shipbuilding. It is a key component for static sealing of equipment such as pressure pipelines, valves, pumps, and heat exchangers in China. Therefore, choosing and using high-quality metal wrapped gasket products is of great significance in reducing and eliminating running, emitting, dripping, and leaking, ensuring the safety of host equipment, and the normal operation of pressure pipelines.

1. Product description: Gasket is a semi metal sealing gasket designed for high temperature and high pressure applications, with rich elasticity and the advantage of limiting fastening force according to installation thickness. It can be used not only in thermal power plants, nuclear power plants, steam turbines, and ship steam systems, but also in processing pipelines and heat transfer oil pipelines in petroleum refining and petrochemical industries.Required gasket compression ratio: original thickness(mm) 2.5 3.2 4.5 7.2。Compressed thickness(mm) 1.9－2.0 2.3－2.5 3.2－3.4 5.2－5.5。Based on practical application experience, the recommended thickness for spiral sealing gaskets is3.2mm and 4.5mm. The thickness after compression is maintained at 2.4mm and 3.3mm. By changing the tension of the wrapped steel strip, the density (hardness) of the wrapped gasket can be adjusted to meet the needs of various application parts.

Features and advantages:Advantages of winding the body: As a sealing element, it is alternately wound with V-shaped steel strips and soft non-metallic filling materials. Excellent resilience, capable of automatically compensating for pressure thermal cycles and vibrations in pipeline systems

Advantages of outer ring: Ensure that the gasket is positioned in the center of the flange sealing surface, while limiting excessive compression of the winding body

Advantages of Inner Ring: It prevents the winding body from buckling inward due to insufficient rigidity, and fills the gap between the gasket and the flange surface of the container or pipeline to avoid interference with fluid flow and erosion of the gasket caused by this gap

Advantages of color identification and steel stamp marking: easy to identify size, pressure, and material

Advantages of standard and non-standard sizes: ASME B16.20, API601, DIN2699,BS3381, JPI-7S-41, JIS B2404,HG20610-97, HG20631-97,GB4622.2-93, SH3407-96, JB/T90

Advantages of various gasket types: SW, SWI, SWC, and SWCI types and designed according to customer requirements. Various types of gaskets can meet chemical compatibility and flange types

Advantages of application scope: Sealing of pipeline flanges, valves, pump inlets and outlets, heat exchangers, reaction towers, observation holes, handholes, shell covers, and other parts in contact with steam, oil and gas, solvents, gases, heat transfer media, etc. with high temperature and high pressure, low temperature and deep cold, and rapidly changing operating parameters.
