Spiral Wound Gasket With A Certain Degree Of Flexibility Of The Graphite Has A Very Good Temperature Resistance
- Aug 14, 2017 -

Spiral Wound Gasket is a high-quality gasket, in many devices have applications, some of its excellent performance is other than the gasket can not be compared, it is by the sprint metal plate or metal mesh plate and expanded graphite A compound that suppresses the particles. It is usually stamped or cut from a reinforced graphite sheet by professional gasket cutting equipment. Enhanced graphite gasket commonly used in the inner layer of reinforced materials ss304, ss316 or tinplate, the thickness of 0.05 ~ 0.2mm, the form of a sponge plate reinforced composite gasket, stencil reinforced composite gasket, flat reinforced composite gasket. So how can we buy high quality products? In the purchase need to pay attention to what? 1, according to working conditions, flange seal type selection to enhance the graphite gasket. 2, in the purchase to see if it has a certain flexibility of the graphite has a very good temperature resistance, can be used in the range of minus 260 degrees to 1500 degrees, and has a very good corrosion resistance, stress relaxation rate is not very large , The use of its processing from the seal has a very good sealing effect. 3, compression rate,Spiral Wound Gasket rebound rate and sealing performance is an important indicator of sealing and strengthening the graphite gasket, in general, to meet the requirements of the compression rate under the premise of the higher the better the rebound rate; and meet the resilience standard Requirements of the premise, the compression rate of the test value is also bigger as well. Should choose a good sealing performance, moderate compression rate and high water plate plate price rebound rate as much as possible products. 4, the selection of quality management system sound and effective operation of the production enterprises of the product, the best choice for holding special equipment (pressure pipe components) manufacturing license and effective type of aramid fiber packing test report of the enterprise products.

     1, the selection of quality management system sound and effective operation of the production enterprises of the product, the best use of special equipment (pressure pipe components) manufacturing license and effective type of test report of the enterprise products.

 2, the main surface of the gasket does not allow the impact of sealing performance of the scars, voids, rugged and rust defects. Gasket body surface non-metallic belt should be uniform, appropriate higher than the metal belt, interlayer texture should be clear, but can not reveal the metal belt. Spiral Wound Gasket spacing should be uniform, there should be no fused or over-melting and other defects. Strengthen the ring surface should not have burrs, rugged, rust and other defects, the upper and lower sealing surface of the main body and the ring between the upper and lower ring surface should be equal to the inner ring and the gasket between the main body should be tightly fixed,Spiral Wound Gasket can not be loose; Gasket between the main body should be positioned and may be appropriate to loose.

  3, compression rate, rebound rate and sealing performance is an important performance indicators of gaskets, in general, to meet the requirements of the compression rate under the premise of the higher the better the rebound rate; and meet the requirements of the rebound rate standards Prerequisite,Spiral Wound Gasket the compression rate of the test value is also bigger as well. Should choose a good sealing performance, moderate compression rate and rebound as much as possible products.

  4, according to working conditions, flange sealing type selection of gasket.
