Allowable deviation of outer diameter | ±2.0 | ±2.5 | ±3.0 | ±3.5 | ±4.0 | ±6.0 | ±8.0 | |
Steel wire | Wire diameter,mm>= | 1.6 | 2.0 | 2.6 | 3.5 | 4.5 | 5.0 | 5.5 |
Wire spacing, laps/m, >= | 55 | 40 | 34 | 25 | 19 | 19 | 17 | |
Thickness of protective layer,mm,>= | 0.3 | 0.34 | 0.36 | 0.38 | 0.42 | 0.60 | 0.60 | |
Note: The diameter of the steel wire can be increased and the number of turns per meter can be reduced, but it should meet the requirements for pressure resistance and flatness. | ||||||||
Longitudinal tensile strength,KN/5cm,>= | 1.0 | |||||||
Longitudinal elongation,%,>= | 12.0 | |||||||
Transverse tensile strength,KN/5cm,>= | 0.8 | |||||||
Transverse Elongation,%,>= | 12.0 | |||||||
Bursting strength of ball top,KN,>= | 1.1 | |||||||
CBR bursting strength,KN,>= | 2.8 | |||||||
Permeability coefficient K20,cm/s,>= | 0.1 | |||||||
Equifinal aperture O95,mm | 0.06~0.25 | |||||||
Note: Only one of the ball bursting strength test and CBR bursting strength test is required. Due to the small area of the filter cloth, the ball bursting strength test should be used for FH50; CBR bursting strength test is recommended for FH 80 and above. | ||||||||
