| Description: |
Metal gaskets include corrugated metal gaskets, metal serrated gaskets and metal ring gaskets.
Corrugated metal gasket is the concentric waveform ring processed from a flat metal ring through molding, rolling or turning, with the nonmetals like the expanded graphite or PTFE pasted on the surface. Compared to the serrated gasket, its inside linings are of a variety of thickness, such as 3mm, 2mm, 1mm, 0.5mm, etc., and the pitch of waves differs in accordance with the width of metal sealing surface, generally being 3mm, 4mm, and 6mm.
Product Applications:
This product has been proven to be of reliable and effective sealing performance when it is put in flanges and switch devices, especially of stronger sealing property in the large smoke and gas pipelines, flanges under low pressure or high temperature, or distorted flanges. It can also avoid the problem that non-metallic gaskets are difficult to install and use in large pipelines.
âÂÂÂÂOutstanding mechanical strength and thermal conductivity;
âÂÂÂÂApplicable at high temperature;
âÂÂÂÂWith no limits for the sizes of gaskets;
âÂÂÂÂEasy to select metal linings according to different working conditions;
âÂÂÂÂAlso applicable to large size pipelines and uneven sealing surfaces

Surface Liningsï¼ÂÂ
Flexible graphite, PTFE, asbestos sheets, non-asbestos sheets, etc.;
The thickness of two-sided surface lining is generally to be 0.5 mm, 1.0mm, and 1 .5 mm.
Metal serrated gasketï¼ÂÂis processed into concentric grooves on both sides of stainless steel flat gasket by use of precision lathes. Flexible graphite, PTFE, non-asbestos sheets or other soft metals can be pasted on its two sides according to different mediums. It can be also directly used without sealing layer, and achieves a good sealing effect. But it will easily damage the surface of the flange under a high pressure.
Gasket Types:
Basic metal serrated gasket
Metal serrated gasket with outer ring (integral)
Metal serrated gasket with outer ring (Floating)
Split metal serrated gasket with outer ring chooses less expensive metals such as carbon steel as its outer ring of 1.5mm thickness. It is more flexible and economic than the integral type, and its lining metal can be repeatedly used.
Product Applicationsï¼ÂÂ
Under the condition of lower pre-tightening force, this gasket is the first choice. The soft sealing layer avoids direct metal-to-metal contact and can be bonded reliably and closely, therefore preventing the metal flange from being damaged even under high load. Serrated compound gasket, the ideal substitute of traditional metal jacketed gasket (MJG), is especially applied in flange joints of heat exchangers, containers and reactive kettles under high temperature, high pressure and alternating working conditions. Pressure range: 64-25Mpa

Surface Linings:
Flexible graphite, asbestos sheets, non-asbestos sheets, etc.;
PTFE, mica plate, lead, etc.;
The general thickness of two-sided surface lining is 0.5mm.
Metal ring gasketsï¼ÂÂare the sealing gaskets of various forms processed from the solid metals of various materials through mechanical cutting by high precision CNC lathes. Featuring small installation area and high pretension pressure, they are applied in sealing parts of pressure vessels, valves and cylinders in the environments of high temperature, high pressure and high corrosiveness.
