MATERIALS FOR SLEEVE PIPE CONNECTOR |
| |
Materials for sleeve pipe connector should have tensile strength σ ь≥520 MPa , shrinkage rate ψ ≥ 40% and elongation rate δ ѕ≥ 25% as specified in GB/T1220, GB/T699, GB/T3077 and GB/T1591; the ratio of tensile strength σ ь and yeild strength σ ѕ should be greater than 1.4. Meanwhile, quality certificate for mate- rial should be provided. Materials for sleeve pipe connector should be austenite stainless steel OCr18Ni9 (304) or OCr17Ni12Mo2 (316). |

MATERIALS FOR STEEL STRANDS |
| |
Steel strands or steel cables to match sleeve pipe connectors should be steel strands or steel cables specified in GB/T9944 and GB/T8918. Meanwhile, quality certificate for material should be provided. Materials for steel strands in this |
|
|
|
standard chart are austenite stainless steel OCr18Ni9 (304)
or OCr17Ni12Mo2 (316) where nominal diameter range
is 6mm-28mm, tensile strength range is 1000MPa
~1400MPa and actual value is 1300MPa. |
