Why are highland barley paper gaskets used for the reducer oil tank flanges?

There are also asbestos-free gaskets. Asbestos gaskets are now recognized as carcinogenic. So why do asbestos-free gaskets, whether they contain a small amount of asbestos or none at all, still look similar to asbestos gaskets? What material is it exactly?

Can tetrafluoro gaskets be used as well?

What is a transmission oil tank flange? Is what LZ is referring to the gearbox? These days, gearboxes generally don’t require gaskets; it’s sufficient to apply sealant directly. When using gaskets, the thickness of the gasket must be taken into consideration; the material of the gasket is less important, as long as it can provide a sealing effect.

Highland barley paper is a paper product processed with fluoroplastics. It is generally used in mechanical and electrical products. It is commonly used as a spacer in the indirect bonding of hard metal parts. It has good insulation properties, flexibility, water resistance, wear resistance, oil resistance, aging resistance, and excellent flame retardancy.

Asbestos pads are made from asbestos fibers and rubber as the main materials, along with rubber additives and fillers, through processes such as mixing, hot-rolling molding, and vulcanization. Aspirin fiber gaskets can be divided into ordinary rubber gaskets and oil-resistant asbestos rubber gaskets, depending on their formulation, process properties, and applications. Uses: Suitable for sealing the tank openings, manholes, and handholes of reaction kettles, as well as boiler manholes, flue ducts, and steam trap seals.

Fuel tank sizes are generally large and arranged in a non-circular shape; as a result, maintenance units typically lack the stamping dies necessary to carry out mechanical processing. Therefore, the processing difficulty of tetrafluoro gaskets is much higher than that of highland barley paper. At the same time, the thickness of the PTFE gasket must also be greater than that of the highland barley paper.

Highland barley paper is relatively thin, making it easy to process into gaskets； The gasket thickness should also be considered, as it may affect the installation clearance of the fittings.

I’ve hardly ever seen flanges made of highland barley paper (where do the flanges for reducers come from?) One end is connected to the motor and the other end to the pump; it has oil seals. Gland covers are often made of highland barley paper, asbestos, PTFE gaskets, or rubber gaskets. Sometimes no gaskets at all are used – just a little 704 sealant will do, as long as there is no oil leakage. Since the oil tank is not under pressure, the requirements are not high

It should be a bearing cover:); it looks like a blind flange
