High pressureFlangeThe key is used in the installation of pipelines. High pressureFlangeConnection is to fix two pipes, tubes or instruments separately in oneFlangePlate, in the middle of 2 flanges, addFlangeThe pads are tightened together with anchor bolts. Some tubes and instruments are already built-in.FlangeThe disc is also attributedFlangeJoin. At this stage, the key includes traditional high pressure.Flangeand high pressure self-tighteningFlange.
Commodity characteristics:
1. The basic principle of sealing is attributed to plastic deformation.
2. Connect by screws.
3. Anchor bolts shall bear the ground stress of tensile resistance and temperature difference, and bear many additional ground stresses such as bending distance and torque distance.
4, the volume is huge, the net weight is heavy, the installation of accurate positioning is very difficult.
5, the sealing performance is not stable, especially in the harsh (high temperature, high pressure, toxic material) conditions are very easy to cause leakage, resulting in serious harm. The use of high-pressure flanges: high-pressure flanges are used in the installation of pipelines.FlangeConnection is the key interface mode of pipeline engineering construction, and the connection between the key joint pipe and the middle of the pipe has the key effect and use value.
high pressure flange commodity performance:
1, wear resistance: porcelain composite seamless steel pipe lining porcelain layer Al2O3 composition of more than 95%, the microscope strength is HV1000-1500, so it has a very high wear resistance, wear resistance than heat treatment of low carbon steel after more than ten times, better than tungsten carbide tool.
2, corrosion resistance porcelain is neutral raw materials, organic chemical performance is stable, with excellent corrosion resistance and alkali resistance, can resist a variety of strong oxidants, citric acid, solvents, etc., its corrosion resistance level is ten times the stainless steel plate.
