ISO 15630-3:2002 steel for the reinforcement and prestressing of concrete-Test methods- Part 3: Prestressing steel, MOD

ISO 6934-4: 1991 Steel for the presressing of concrete – Part 4: strand, NEQ

GB/T 5224-2014 Steel strand for prestressed concrete

GB/T 10120-1996 Metallic materials -Tensile stress relaxation - Method of test

GB/T 21839-2008 steel for prestressed concrete -Test methods

Parameters:

Features:

1. It can show the relative diagram of residual testing power/relaxation rate with time, and relative diagram of temperature and time.

2. The stress relaxation properties of the specimen in 1000hours can be calculated by the machine.

3. It can gain the stress relaxation properties of specimen automatically and print a complete testing report.

    High Strain Dynamic Pile Tester (Also named PDA by PDI company. )  ;  Low Dynamic Pile Tester (PIT or PET for short); Untrasoic Crosshole Pile Tester for 2, 3 ,4 channels.; Drillhole Monitor  (Also named Koden from Japan company. )

High Strain Dynamic Pile Tester projects at field. If clients need, we also can do the testing compare with PDA from PDI company. We already have done testing at different countries. We got very good feedback from our professional pile testing clients and relative company. 

Low Strain Dynamic Pile Tester at field with our software;  Static Load Pile testing at field with our software. 

Drill hole monitor testing at field with 100meter depth, with automatic stop function to save untrosonic sensor drop in wells making lost for inspection company.  We also can supply drillhole monitor with 150m depth.

2. Optical Fiber Bragg Grating for temperature and Strain gauge

As FBG strain gauge and temperature sensor are popular in construction monitor system, we also concentrate in this aspects for many years. DTS. DVS system.
