與普通平板法蘭墊相比，做到了管網(wǎng)的安全性和穩(wěn)定性。從降低產(chǎn)銷差率、安全供水的角度出發(fā)，法蘭墊的作用非常重要全盤止水法蘭墊是在現(xiàn)有光面法蘭墊的基礎(chǔ)上開發(fā)出來的一個具有獨特結(jié)構(gòu)的新型法蘭墊，該產(chǎn)品有以下優(yōu)勢:
　　1.在其兩面的密封面上均勻分布適量同心止水線，每條同心止水線都具有獨立的密封作用，抗壓變性能強，安裝到表面有凹凸、加工粗糙甚至被腐蝕的法蘭盤上同樣具有良好的密封作用。
　　2當(dāng)水壓過大時，普通平板法蘭墊片容易產(chǎn)生位移，甚至從螺栓孔之間直接沖出，使用此種全盤法蘭墊后，法蘭墊的位移量僅在螺栓與
孔的非常小的間隙之間，做到了管網(wǎng)的安全性和穩(wěn)定性。

　　3.由于采用了同心球面線設(shè)計，使用時能以最小的緊固力達到最佳的密封效果，并能有效地減輕水壓沖擊力的影響，從而達到有效長久的密封效果。
　　4.設(shè)計了準(zhǔn)確的安裝定位裝置，安裝時只需一人即可操作，從而提高了工作效率，節(jié)省了安裝成本。

The FULL FACE FLANGE Gasket is a high performance gasket for flanged joint piping systes. The most vulnerable element of a pipingsystem is the joint. Many times, the weakest part of the joint is the gasket that is used. Lots of time and money are spent in the design antspecification of the pipe, fitings, valves, and various components of the project to insure the piping system is able to withstand therequirements of your application, only to have allthat time and expense undermined by the owest cost item in the piping system; a flat sheetof thin rubber between the flanges. Huayi offers a solution that wll provide peace of mind through superior performance, the FULL FACEFLANGE Gasket. Below we list some of the high performance features this product provides.

Pressure:
By combining the effectiveness of "o-ring" technoloay into a molded flat gasket, the FULL FACE FLANGE-TYTE Gasket can operate safelyat high internal pressures, high velocities, and stil handle the common occurrence of surges in pressure without fear of joint leaks. Thegasket may also help to resolve installation issues that arise such as imperfections in the flange face, flange alignment, and pipe oequipment alignment.

Torque:
The FULL FACE FLANGE Gasket employs "bulb type" rings on the faces of both sides of the gasket. This provides 3 times the sealing peaceof mind than gaskets that provide only (1) bulb, or none at all. By using "bulb type' rings on the face of the gasket, the bolt torque requiredto effectively complete the seal is greatly reduced. This results in reducing stresses on flanges,bolts, and nuts in addition to providing a muchsafer and dependable assembly for the installer.
