Metal Spiral Wound Gasket

Metal Spiral Wound Gasket,

Product Detail:
Spiral wound gasket is designed for high temperatureand high pressure have been used to rationalize the design of high-performance semi-metallic gaskets, there are a wealth of flexibility can be restricted in accordance with the installation of the thickness of the advantages of fastening force, not only can be applied to thermal power stations, nuclear power plants and steam turbine, the ship's steam system, but also widely used in petroleum refining, petrochemical and pipeline industries to deal with heat transfer oil pipeline.
Gasket compression ratio requirements:
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
In accordance with the practical application of experience, spiral wound gasket recommended thickness of 3.2mm and 4.5mm. After the post-pressed to maintain the thickness of 2.4mm and 3.3mm in Winding through the changes in the tension steel, spiral wound gasket can change the density (hardness) to meet the needs of each application site.
Metal materials:
Carbon steel (CRS), 304SS (304), 304LSS (304L), 316LSS (316L), Monel 400 (MON), titanium (TI),
Nickel 200 (NI), Hastelloy C (HAST C), Yin harsh Nickel 600 (INC600)
Non-metallic filler material:
Flexible graphite (FG): 650 °C; polytetrafluoroethylene (PTFE): 260 °C; non-asbestos (NON-ASB): 500 °C; Asbestos (ASB): 500 °C; mica paper (MC): 850 °C; ceramic fiber paper (CER): 1300 °C Note: may also have recourse to other metallic materials, it should be explained in order for the oxidation of medium is less than or equal to 450 °C to apply pressure 420BAR Low stress can be provided in the spiral wound gasket spiral wound gasket with the ordinary, like the effect of a perfect seal. It is designed only for just under the lower edge can be tightened up to a certain amount of compression of the sealing effect and ideals. Pads used in low stress, such as the pressure level of 150 lbs flange connections, in which parts of the traditional spiral wound gasket as a result of their requirements, taking into account the stress might have been tightened to allow the design of more than stress and no longer apply.
1.overall red inner ring and outer ring system, the reliability of higher voltage.
2.Quality-filled non-metallic materials, better sealing performance.
3.forming a specially designed point of view, a better compensation performance compression rebound.
4.CNC automatic gasket molding equipment, with automatic adjustment in accordance with nominal pressure pads pressed edge technology, automatic control technology gasket size, automatic welding control technology, ensuring the high quality standard gasket.
Features and advantages:
1.wound ontology advantages: as a sealing component,
by the V-shaped steel band and soft non-metallic filling material from the turn of winding. Good
elasticity, to the pressure piping system for thermal cycling and vibration automatic compensation
2.outer advantages: precision determined to ensure that gasket flange sealing surface is located in the central, while restricting excessive compression wound ontology
3.inner advantages: to prevent entanglement of rigid body due to lack of inward buckling occurred at the same time to fill the container or pipe gasket and the gap between the flange in order to avoid this gap, as well as interfere with the flow of fluid caused by the red fluid on the pads corrosion.
lor logo and Seal tag advantages: easy to identify the size, pressure, material.
5.size standards and the advantages of non-standard: ASME B16.20, API601, DIN2699, BS3381, JPI-7S-41, JISB2404, HG20610-97, HG20631-97, GB4622.2-93, SH3407-96,
JB/T90
6.the merits of the various types of pads: SW, SWI, SWC and SWCI request of the customer, type and design,all types of gaskets to meet chemical compatibility and flange type
7.application advantages: high temperature and high pressure, low temperature cryogenic as well as dramatic changes in operational parameters of steam, oil,solvents, gases, heat transfer media, such as access tothe pipeline flanges, valves, pumps the import and export of heat exchanger, reaction tower to observe the holes, hand holes, and other parts of the shell of the sealed cover.
