Got-400r metal flat gasket can also be processed into the inner and outer ring of the spiral wound gasket. We will punch the gasket that with the size smaller than 8fª by punching machine, and for the one that with large size by lathe. If for the expensive material as ss304, ss316, etc. As long as the sealing plane is not over wide, we will basically use the special ring rolling machine, process by the wire rod, to largely cut cost. The carbon steel outer ring can be coated with zn, white zn, or paint-drying, and the typing will be according to the standards or the demands.
Product structure:
The metal interface flat gasket, choose kinds of solid metal, mechanically cut and processed into kinds of metal sealing gaskets by high precision nc lathe, suitable for the sealing parts of pressure container, valve, cylinder head with high temperature, high pressure, and strong corrosion. General characteristic is installation area small and preload pressure high.
Got-400r metal flat gasket can also be processed into the inner and outer ring of the spiral wound gasket. Got self design and manufacture the ring processing special equipment, outer ring trench cutter, and inner ring chamfering machine. Comparing with the traditional lathe, it is high efficient, low cost, and need no special fixture.

Got kammprofile gasket , generally processed to be concentric groove in the two faces of the stainless steel flat gasket by precise lathes. According to the different medium, w can choose flexible graphite, ptfe, non-asbestos, or other soft metal, to sick to the two faces of the gasket. It can directly be used without sealing layer, and the effect is good. But under the high pressure occasion, it will be easy to do damage to the surface of the flange.
410 basic type kammprofile gasket
410l kammprofile gasket with outer ring (integral type)
410lm kammprofile gasket with outer ring (split type)
Model 410lm split type metal toothed gasket with outer ring, can choose richer metal, e.G. Carbon steel, as the outer ring, and the outer ring thickness can be 1.5mm, more flexible and economic than the integral type 410l, and the lining metal can be repeatedly used.
Product application:
Got toothed combination gasket is the first choice gasket under relatively low preload power, the soft surface of the sealing layer can avoid the direct touch between metal and metal, which is combined reliably and compactly, to protect the metal flange from damaged, even under extremely high load. The toothed combination gasket is especially suitable for the flange connection in thermal exchanger, container, and reaction vessel under high temperature, high pressure, and the working condition altering occasions. It is an ideal substitution for traditional metal jacketed gasket. Operating pressure range: 6.4~25mpa
Overlaying material:
Flexible graphite, asbestos plate, non-asbestos plate;
Ptfe, mica plate, lead, etc.
Generally the thickness of the dual overlaying is 0.5mm
Got-450 ring joint gasket chooses solid metal with kinds of materials, and is mechanically cut and processed into metal sealing gaskets with kinds of forms by high precision nc lathe. It is suitable for the sealing part of pressure container, valve, and cylinder head with high temperature, high pressure, and strong corrosion. General characteristic is installation area small and preload pressure high.

Special-shaped metal gasket
Got-633 is made of 633-1 non-asbestos beater sheet inner lined with metal truss plate (generally the carbon steel with 0.2~0.25mm thickness). It is extensively applied in manufacturing various automobile and motor gaskets. It is an ideal material that will substitute the traditional asbestos gaskets. The product has excellent performance in self expansion, high resilience and long lifespan, etc. Mainly applied in automobile farming machine, motorcycle and engineering etc., it is also can be used in high strength gaskets and cylinder gaskets etc.
Product structure:
Got-633 truss plate reinforced asbestos beater sheet
If stored for a long time, the asbestos will have certain corrosion to the inner lined metal.
