SUNWELL soccer 820
Applicable standards:
1 RX metal ring pad is usually in oil, petrochemical and other high pressure parts widely used;
2RX design using pressure is usually greater than 15000PSI;
3 RX gasket price is usually better than metal oval gasket and metal octagonal pad;
The series 4 RX metal ring pad in API6B models of the flange in the wide application of.
Description:
RX series metal ring pad is in the R series of metal ring pad on the basis of the development and extending out of another type of metal ring pad, the use effect is better than that of R series metal ring pad. It makes the flange contact more closely, outstanding sealing performance.
Tolerance:
The width of 1A: + / - 0.008;
Height of 2H: + 0.008~ 0;
3 OD external diameter: + 0.020~ 0;
4.23 degrees: + / - 1/ 2 degree.
Standard:
RX series metallic ring gaskets for reference : API6A and ASME B16.20.
Particularly worth mentioning is that: in the metal ring pad surface damage, must not be reused.

BX metal ring pad
SUNWELL soccer 830
Applicable standards:
BX metal ring gasket octagonal ring gasket is similar to;
BX metallic ring gaskets used in API6BX flange;
BX metallic ring gaskets for use of the pressure, from 5000LBS to 20000LBS;
Ring pad linear part damage may not be used again.
Description:
BX metal ring pad is installed correctly, make close contact flange, gasket inside and outside completely. All BX metal ring pad are provided with balance holes.
Tolerance:
Width A: + / - 0.008;
Height D: + 0.008~ 0;
External diameter OD: + 0.020~ 0;
23 degrees: + / - 1/ 2 degree.
Standard:
The average value of K1= 0.49, standard deviation of 4.3%. The ring mat work sealed pressure ratio ( along the ring diameter circumferential per unit length of the axial pressure ) for medium pressure 0.49 times, and the leakage rate in the general industry within the scope of.
DIN2505 recommends metal ring connection pad sealing liquid when the K1value is 0.6, no leakage rate requirements.
4Conclusion
In this experiment condition, as long as the metal ring connecting pad processing precision with ISO / DIS7483 requirements, the following conclusions can be drawn:
In 1, a metal ring is connected with the compression pad rebound performance and the pad material hardness between linear relations;
Rebound rate = 1.13* ( HB ) - 106, correlation coefficient r = 0.9.
Type in HB for Brinell hardness value.
In 2, the leakage rate in the range of 1 ~310-5cm3/ cm.s range, a metal ring connection pads ( initial sealing pressure ratio along the ring diameter circumferential per unit length of the axial pressure ) by its material hardness impact, its relationship to approximate as follows:
Sigma * 0= 6.33 x104( HB )2.77
Ring joint gaskets initial seal when the initial sealing pressure for the ring gasket material strength limit value ( sigma0)0.14 times. The initial seal ring cushion coefficient K0 =0.14. Below the DIN2505recommended sealing liquid fetching
K0 = 0.16.
In3, the leakage rate is1~ 310-5cm3/ cm.s range, a metal ring connection pads work sealing coefficient K1= 0.49. Below the DIN2505seals the recommended value of K1 = 0.6.
