Handa Cold Drawn Seamless Steel Pipe

Handa Cold Drawn Seamless Steel Pipe is engineered through a cold drawing process where a larger seamless pipe is pulled through a die and plug without additional heating. This method ensures enhanced dimensional precision, smoother surface quality, and tighter tolerances compared to traditional hot finished seamless pipes.

Designed to meet the high standards required by critical industries, cold drawn seamless pipes are particularly suitable for applications such as heat exchangers, bearings, hydraulic cylinders, and automotive components. The improved mechanical properties and excellent surface finish minimize the need for secondary processing, optimizing productivity and material utilization.

Each batch undergoes stringent quality control testing—including hydrostatic, flaring, crimping, and squashing tests—ensuring long-lasting structural integrity. The use of steel grades such as 10# and 20# further enhances reliability for demanding engineering environments.
