Almen (Almen) tee shot steel strength test commonly used N test piece (test for non-ferrous metals), A test piece (the most common), C specimen (higher intensity) to be measured, A and C test pieces the relationship between the test piece is approximately three times the relationship. As measured by C specimen strength 0.15-0.20C mm equivalent 0.45-0.60A mm. The figure for the C-thick test piece for A thin specimen. During the test, the test piece to measure the deformation of the original, and then the test piece was good card placed tooling blast box, using the same process as the workpiece is injected. Shot over, remove the test piece, measuring deformation arch height. Tee shot blasting coverage coverage means that every point on the number of steel shot was hit piece, someone shot coverage often think: My lower spray nozzle 1 1 work 2 times, you can not meet 200% of the coverage it? first I feel justified, in fact not the case. Coverage measurement is as follows: first the surface coated with a fluorescent glaze or enamel forged alloy thick-tee, then press the workpiece blasting parameters, each jet over the workpiece surface removed, the microscope (magnifying glass) remaining under observation a proportion of the coated surface, as well as 20% of the residual, the coverage rate of 80%. When the residual only 2%, or 98% of coverage, can be regarded as clear that 100% coverage, then there is a time. If it reaches 400% coverage alloy thick-tee manufacturers, which is 4 times the time. Factors 16 5. Coverage of Hebei steel pipe industry Chiho tee strong compression capability. Very high strength stainless steel pipes, galvanized pipe twice, three times copper tube 8-10 times PP-R pipe, well able to withstand shock and vibration specification alloy thick-tee, with watertight, does not burst , fire, earthquake and other characteristics, so it is safe and reliable. Reducing carbon steel tee long service life. Field corrosion test data indicate, the service life of stainless steel pipes up to 100 years alloy thick-tee, stainless steel pipes require little maintenance cost is very high, pay low costs, significant economic benefits.
