● We has long been a domestic and international numerous oil seal mould supply and product research and development equipment, our research and development ability, is the domestic first-class oil seal manufacturer home.
● We provide one-stop sealing solutions, and provide a full range of services, from product design, mold development, stamping skeleton, vulcanization molding, clip, screening and packaging. The entire process would take a shorter, more stable quality.
Gasket installation and use guide:
1. The gasket and flange sealing surface should be cleaned, and there should be no scratches, spots and other defects that affect the sealing performance of the connection.
exist.
2. The outer diameter of the gasket should be smaller than the outer diameter of the flange sealing surface, the inner diameter of the gasket should be slightly larger than the inner diameter of the pipe, and the difference between the two inner diameters is generally taken as the gasket
2 times the thickness to ensure that after pressing, the inner edge of the gasket will not protrude into the container or pipeline, so as not to obstruct the container or pipeline
the flow of fluids.
3. The pre-tightening force of the gasket should not exceed the design requirements, so as to avoid excessive compression of the gasket and loss of resilience.
4. When compressing the gasket, it is best to use a torque wrench. For large bolts and high-strength bolts.
It is best to use hydraulic tensioners. The tightening torque should be based on the given gasket compression through
Calculated, the size of the hydraulic tensioner oil pressure should also be determined by calculation.
5. When installing the gasket, the nuts should be tightened in the order shown on the right. But they should not be tightened once
reaches the design value. Generally, it should be cycled at least 2 to 3 times, so that the gasket stress can be divided into
Evenly cloth.
6. For pressure vessels and pipelines with flammable and explosive media, use a safety valve when replacing gaskets.
All tools, so as to avoid sparks caused by the collision of tools with flanges or bolts, resulting in fire or explosion accidents.

High TEMP. |
Performance | ||||
| NBR | -40 | 120 | Good resistance to alcohol,amines, petroleum oils, and gasoline over a wide range of temperature. Also good resistance to caustic salts and fair acid. Poor in strong oxidants, chlorinated hydrocarbons, ketones, and esters |
||||
| HNBR | -25 | 140 | HNBR is made from NBR by hydrogenation. It has high temperature resistance, abrasion resistance and good physical properties. |
||||
| ACM | -25 | 150 | It is used in diaphragm, hose for automotive application. Good resistance to heat, ozone and oil. Generally attacked by water, alcohol, glycol and aromatic hydrocarbons. The molecular structure contains ethyl acrylate (EA). Butyl acrylate (BA), and methoxy ethyl acrylate (MEA). High BA content get better low temperature resistance, and high MEA content get more oil resistance. |
||||
| EPDM | -40 | 125 | Stable in polar fluids (alcohol, ketone, and glycol), and hydrochloric acid. Due to the low specific gravity, it can compound with large amount filler. |
||||
| VMQ | -60 | 125 | The most widely temperature ranges for application. Good weather and ozone resistance, but poor mechanical property and chemical resistance. |
||||
| FKM | -20 | 250 | Fluoroelastomers have a high degree of chemical stability and are currently the best media resistance of any elastomer. Type 26 fluoroelastomer resistant to petroleum-based oils, diester oils, silicone ether oils, silicic acid oils, inorganic acids, most organic, inorganic solvents, drugs and so on |
