①,1. Technical requirements for gaskets
1.1. Gaskets shall be produced only from one-piece blanks.
1.2. Hardness of material for manufacturing ring gaskets shall be of no more than:
- 107 HB for carbon steel;
- 131 HB for quality steel:
- 160 HB for carbon steel.
Hardness of recommended gasket materials shall comply with those specified in table 8.
Table 8:
Designation of gasiket material | Steel grade, number of standard | Brinell hardness,no more than
Y1 | Steel 0 GOST 380 107
| CT08Kп GOST 1050 98
Y2 | CT 20 GOST 1050 127
| CT 08 GOST 1050 109
K1 | 12X18H9T GOST 5632 160
K3 | 10X17H13M3T GOST 5632 160
Notes :
1. Gaskets Y1 and Y2 are designed for non-corrosion-resistant equipment.
2. Gaskets K1 are designed for the equipment operating in borehole environment with the volume content of C02 up to 6%; gasket K3 are designed for the equipment operating in borehole environment with the volume content of CO2 and H2S up to 25 %.
1.3. Hardness difference of materials of gaskets and flanges or flange groove surfaces contacting with gaskets shall be of no less than 50 Brinell units, unless other norm is indicated in specifications and technical documentation on the product.
1.4. Gaskets made of alloy-free steel shall be produced with a coating. Coating shall be cadmium or zinc in accordance with GOST 9.301. Thickness of coating shall be of 5 to13 microns.
1.5. Sealing surfaces of gaskets shall have no corrosion marks, contaminations,nicks, scratches, dents and other defects. |
