2021 High quality Low Relaxation Seven-Wire Strand For Prestressed Concrete - PC Strand for LNG Tank – Silvery Dragon
2021 High quality Low Relaxation Seven-Wire Strand For Prestressed Concrete - PC Strand for LNG Tank – Silvery Dragon Detail:
This product is suitable for prestressed concrete structures of LNG storage tank projects and using in other low temperature environments. Its structure is 1X7 and the nominal diameter is 15.20mm, 15.7mm&17.80mm. The allowable deviation of the diameter is carried out strictly as per+0.20mm, -0.10mm. The strength grade is 1860Mpa; the total elongation under maximum force (Agt) is required to be ≥5.0%; the fracture after breaking is plastic; the wire section reduction rate (Z) is ≥25%; the diameter of the center wire is not less than 1.03 times of the outer wire diameter. The strand does not have any welding points. It has good low-temperature anchoring performance. At -196+/-5°C, the strand is matched with the anchorage assembly, the anchorage efficiency coefficient(ή) is ≥95%, and the total elongation under the maximum load is ≥2.0% . It is the first choice for post-tensioning engineering of LNG concrete outer tank wall. The product can meet the requirements of prEN10138, EN14620-3 and other standards.
