Non-asbestos gasket
Non-asbestos gasket Peng Nuo PN1500
Non-asbestos gasket PN1500 is an excellent non-asbestos material based on the introduction of foreign advanced production technology. It is made of aramid fiber, high temperature resistant synthetic mineral fiber, oil resistant rubber and other materials. It has special properties such as temperature resistance, pressure resistance, oil resistance, excellent air tightness and compression resilience. It can be tested. A non-asbestos material that replaces imports. It is a 100% high-quality environmentally friendly material that does not contain asbestos. It has been exported to Europe and the United States and many other regions. Wires or graphite can be entrained according to customer requirements.
Application medium: various gases, water, water vapor, chemical solvents and various oils, 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.
At the same time, our company agents import the following non-asbestos materials: KLINGER (Australia), BELPA (Spain), FRENZELIT (Germany), VALQUA (Japan), DURABLA (Canada), NOVUS (UK), TESNIT (Europe)
Main features of non-asbestos gaskets:
1. One hundred percent does not contain asbestos, and new environmentally friendly materials can be exported to major developed regions such as Europe and America.
2. Good temperature resistance, pressure resistance and compression resilience
3. Wide applicability, oil resistance, medium resistance and air tightness.
4. Higher mechanical strength material is easy to cut and form.
Classification of asbestos-free gaskets:
1. Asbestos-free gaskets can be divided into two types according to the production process of the material: the roll press method produced by the CAF (production of compressed asbestos rubber sheet) method and the copy board produced by the copying method (paper making method). Belongs to the new environmentally friendly sealing products. Roller plates are generally used for pipe flange sealing, and ZD-G1500 is a type of roll plate. The plate is mainly used for sealing parts of motor vehicles such as engine gaskets, cylinder gaskets for internal combustion engines, and exhaust pipe gaskets.
2. According to the physical performance grade, it can be divided into three different grades of low pressure, medium pressure and high pressure, as well as special anti-asbestos gaskets such as oil resistance, acid resistance, pressure resistance, high temperature resistance, refrigeration refrigerant plate, airtight plate and marine sealing plate. On the basis of the above materials, it can be reinforced with wire, coated with graphite to increase temperature resistance, graphite-free non-asbestos graphite plate, etc. Other properties without asbestos board and various gaskets can be customized according to customers' special needs.
Non-asbestos gasket material specifications: ?
Roller plate width × length (mm): 1500 × 4500 1500 × 4000 1270 * 3810, can be cut; thickness (mm): 0.4 ~ 5.0?
The width of the plate is 1500; the whole multiple of the length is 50000; the thickness (mm): 0.3~1.2
Can the special specifications be agreed with the customer?
※ All products with a thickness of 0.8mm or more can be reinforced with clip wire mesh, can be coated with graphite and double-sided anti-stick treatment, the color can be customized according to customer requirements.
