General Provisions 3.1 Based on the primary function, the piping support and hanger may be classified as: a) Bearing piping load: 1) Constant-force spring support and hanger; 2) Variable spring support and hanger; 3) Rigid support and hanger; 4) Sliding support; 5) Rolling support and hanger; b) Limiting piping displacement 1) Guiding support; 2) Limited support; 3) Fixed support; c) Control piping vibration 1) Antivibration device; 2) Damping device. 3.2 Structural members of support and hanger shall have enough strength and rigidity, and shall be as simple as possible. Except standard support and hanger parts, support and hanger structures and joints shall be treated with strength and rigidity calculation. 3.3 The spacing interval of support and hangers shall be less than or equal to the allowable span of piping. 3.4 If the concentrated loads like valves exist, the support and hanger should be arranged close to the concentrated load. 3.5 The support and hanger should be installed on the straight pipe section, and should not be installed on the position of higher local stress. 3.6 Piping saddle shall be equipped for the piping with thermal-protective coating, which is laid horizontally on the support. As for the vertically-laid piping with thermal-protective coating, the structures like reinforcing plate or lug shall be installed on the piping section of support to protect the thermal-protective coating. 3.7 As for carbon steel piping which the conveyance medium temperature is equal to or higher than 400℃, alloy steel, stainless steel pipe, and piping required post-weld heat treatment, clamped-in style saddle and pipe hanger, or support and hanger with same material under-boarding shall be adopted preferentially. 3.8 As for overhead unease-welded piping, frequently-disassembled piping and lining pipe, clamped-in style saddle and piping hanger should be adopted. Cold insulation saddle and piping hanger shall be installed for cold insulation piping. 3.9 If the hanger has horizontal displacement, double ends of tension bar shall be swing joint, and the tension bar shall be long enough.
