High Pressure Process Filter
Ⅰ. Filter Applicable Ambient
(Ⅰ)Temperature
A.Metal material applicable temperature scope:
Carbon : -10~200℃
Low alloy: -40~400℃
S.S, Ni and Ni alloy, Ti and Ti alloy：-190~400℃
B. Sealing material applicable temperature scope:
Buna-N: -30~100℃
Viton: -30~150℃
Asbestos plate: ≤300℃
Metal graphite spiral wound: ≤650℃
(Ⅱ)Pressure Rating
Filter common design pressure: 0.6Mpa, 1.0Mpa, 1.6Mpa, 2.5Mpa, 4.0Mpa, 5.0Mpa, 6.3Mpa, 10.0Mpa. When operating Temperature goes up, material’s mechanical strength will go down, and its actual loading capacity will go down too, then we shall choose filter higher than nominal pressure rating to meet the requirements of high temperature.
(Ⅲ)Medium
Different filtering mediums’temperature, viscosity, physical and chemical properties affect filter’s structure and material selection.
