2.7 Bolts of the same specification should be used for flange connection, and the installation direction should be consistent. After the bolts are tightened, they should be in close contact with the flange without wedge seams. When washers are required, there should be no more than one per bolt.

2.8 When the pipeline installation encounters one of the following situations. Bolts and nuts should be coated with molybdenum disulfide grease, graphite oil or graphite powder:

2.8.1 Stainless steel and alloy steel bolts and nuts.

2.8.2 The design temperature of the pipeline is higher than 100°C or lower than 0°C.

2.8.3 Outdoor installations.

2.8.4 It is in an atmospheric corrosive environment or transports corrosive media.
