Product Details

Asbestos rubber gasket Peng Nuo PN1400

Asbestos rubber gaskets, also known as asbestos gaskets, are made of asbestos fiber, styrene-butadiene, nitrile, natural, EPDM rubber, supplemented with rubber compounding agent and filler, after mixing, hot roll forming, vulcanization, etc. production. Asbestos gaskets are mainly used in the sealing of medium and low pressure flange connections.

Application medium: suitable for sealing water, steam, oil, solvent, medium acid, alkali, etc.

Industry equipment: products are widely used in power generation, metallurgy, shipbuilding, petrochemical and other industrial applications. Water, steam, oil and other media sealing pipe flanges, valves, heat exchangers, pressure vessels, mechanical equipment and engines, compressors, internal combustion engines Industrial equipment such as machinery, instrumentation and heating.

The main features of asbestos gaskets:

1. Good temperature resistance, pressure resistance and compression resilience

2. Wide applicability, oil resistance, medium resistance and air tightness.

3. Higher mechanical strength material is easy to cut and form.

According to the temperature and pressure used, it can be divided into low pressure asbestos rubber gasket, medium pressure asbestos rubber gasket and high pressure asbestos rubber gasket.

Classification of asbestos gaskets:

Asbestos rubber gaskets can be divided into ordinary asbestos rubber gaskets and oil-resistant asbestos rubber gaskets according to their formulation, process performance and application. According to the physical performance grade, it can be divided into three different grades: low pressure, medium pressure and high pressure. It can also be reinforced with wire on the basis of the above materials, and the graphite can be added to increase the temperature resistance. Other properties can be customized according to the special needs of customers. Various gaskets.

Asbestos gasket material specifications:

Roller plate width × length (mm): 1500 × 4000 1270 * 3810; 1500 * 4500 can be slit; thickness (mm): 0.4 ~ 6.0mm

Can the special specifications be agreed with the customer?

※All products with a thickness of 0.8mm or more can be reinforced with wire mesh, can be coated with graphite and double-sided anti-stick treatment, the color can be customized according to customer requirements.
