Hot-rolled or cold-rolled (dial) seamless pipes from high-quality carbon structural steel. It is mainly made of steel No. 10 and No. 20. In addition to ensuring chemical composition and mechanical properties, it is required to carry out hydraulic test, crimping, flaring and flattening. Hot rolling is delivered in a hot rolled state, and cold rolled (dial) is delivered in a heat treated state. Junde Steel Tube Co., Ltd. provides a seamless management theory weighing method: Seamless management theory calculation formula: (outer diameter – wall thickness) × wall thickness × 0.02466 = weight of seamless pipe per meter {kg}
