CPT Parts

TMC combines two different materials
to create parts with high durability and wear resistance.

CPT Parts

  • CPT Parts
  • CPT Parts
  • Overview
    1. 1) A dual structure transporting pipe with high wear resistance and durability. An important component of concrete pump truck (CPT)
    2. 2) The optimal wear-resistance material and centrifugal casting method : Lifetime is 5-7 times longer than conventional single pipe
  • Pipe manufacturing method: Horizontal centrifugal casting
  • Material : High Chrome Casting Pipe (HCCP)
  • Characteristics: Ultra-hard chrome carbide inside the material → wear resistance enhanced

Hardness testing

Hardness test comparative graph
  • Hardness analysis : Use Rockwell test to test HRA hardness
  • Measurement method
    : Measure surface hardness of inside 7 times and take the average
  • Measurement result : A company > B company > TMC
  • Characteristics
    : Hardness value is widely distributed due to the effects of chrome carbide inside. However, the overall average hardness is low and therefore the product is superior compared to other products that are heat-treated.

Abrasion test

Abrasion test comparative graph
  • Abrasion resistance analysis
    : Soil abrasion test according to ASTM G65-B standard
  • Test method
    : Represent the amount of wear before / after the test
    using the wheel speed-6,000rpm and 60,000 cycles.
  • Test result
    : superior abrasion resistance (TMC> A company> B company, in that order)
  • Characteristics
    : The good test result is due to the presence of primary chromium carbide inside HCCP, which has excellent wear resistance.
