JB982-77 Combination of metal-bonded sealing Washers production and manufacturing standards

The JB982-77 combination metal-bonded sealing washer standard is commonly used in the machinery industry as a gasket standard that applies to various sealing and fixed connection occasions.JB982-77 combination metal-bonded sealing washers are widely used in gasket standards and are relevant to machinery, equipment, automotive, marine, and other industries. The standard specifies the material, size, shape, and technical requirements of combination washers.

JB982-77 material requirements for combination metal-bonded sealing washers

According to the standard of JB982-77 combination metal-bonded sealing washers, the material of combination washers should generally be carbon steel, stainless steel, alloy steel, etc. According to the use of the environment and demand, other materials, such as copper, aluminum, etc., can also be selected. At the same time, the strength and hardness of the material also need to comply with the standard provisions.

JB982-77 combination  metal-bonded sealing washers size and shape all kinds of types:

The JB982-77 standard for combination washers specifies the size and shape of combination washers. According to different connection requirements, the combination washers can have various shapes, such as round, square, oval, etc. At the same time, the standard also specifies the diameter, thickness, and other dimensions of the combination washer to ensure its fit and seal with the connection.

1. High-Pressure-Rated Metal-Bonded Sealing Washers

Able to withstand pressure greater than 3,000 psi, these one-piece bonded washers create the tightest seals.

Zinc-plated steel washers are corrosion-resistant in wet environments. Use them under partially threaded nuts or bolts with a smooth shaft under the head. The Buna-N rubber seal has excellent abrasion resistance and good oil, weather, and chemical resistance. Washers are reusable.

Stainless steel washers are bonded to a PVC sealant that, when tightened, creates a waterproof 360° seal around your fastener's threads. They are not reusable. Three hundred four stainless steel washers are more corrosion-resistant than zinc-plated steel washers. They also have good chemical resistance. Three hundred sixteen stainless steel washers resist chemicals and salt water and may be mildly magnetic.

2. Metric High-Pressure-Rated Metal-Bonded Sealing Washers.

Able to withstand pressure greater than 7,000 psi, these one-piece bonded washers create the tightest seals. They are zinc-plated steel for corrosion resistance in wet environments. The Buna-N rubber seal has excellent abrasion resistance and good oil, weather, and chemical resistance. Washers are reusable.

3. Pressure-Rated Metal-Bonded Sealing Washers

These washers are rated to withstand pressure up to 100 psi. One-piece rubber-to-metal bonded washers create a more robust seal than metal or rubber alone. Made of 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. The silicone seal has excellent weather resistance. Washers are reusable.

JB982-77 technical requirements of the combination of metal-bonded sealing washers.

1. Surface treatment: According to the standard requirements, the surface of the combination of washers must be treated accordingly to increase its corrosion and rust resistance.

2. Sealing performance: JB982-77 is a combination of washers as part of the connection; its primary function is to ensure the sealing of the connection. Therefore, the standard specifies the combination of gasket sealing performance requirements, such as compression deflection rate and filling compression value.

3. Heat resistance: The washers used in the use process must withstand specific temperature changes, so heat resistance is also an essential standard requirement. The standard specifies a combination of gaskets in a particular stability and deformation temperature range.

4. Wear resistance: the combination of washers in mechanical movement will be subject to a certain amount of friction and vibration; the standard requires a certain degree of wear resistance to ensure its service life and the reliability of the connection.

5. Removability: combined washers are part of the connection, and the ease of disassembly and assembly is also an essential technical requirement of the standard.

JB982-77 combination washer standardization regulates the production and use of combination washers to ensure that people from all walks of life use safe and reliable combination metal-bonded sealing washers. At the same time, it promotes the upgrading and development of production technology of combination washers.

Summarized:                              

The JB982-77 combination washer standard detailed provisions for the combination of the material, size, shape, and technical requirements of the washer content. The standard for the mechanical and manufacturing industry's production and use of combination industrial washers provides a basis and promotes the field's technical progress and development.
