Mechanical Properties Tests: These include flattening tests, flaring tests, bending tests, and hardness tests, which are conducted to evaluate the mechanical properties of steel tubes such as tensile strength, yield strength, elongation, and other relevant indicators.
Hydrostatic or Pneumatic Pressure Tests: Steel tubes undergo hydrostatic or pneumatic pressure testing to check their airtightness and weld seam strength. This is a crucial step in ensuring that the steel tubes can withstand a certain internal pressure during use.
