RF series high-precision stainless steel tube mill line can be generally divided into three types, including RF20 type, RF40 type and RF60 type, each with different specifications. RF20 precision stainless steel tube mill line can produce welded tubes with a diameter ofΦ8-25.4mm and a wall thickness of 0.5-1.0mm. The tube welding varies in speed, ranging from 0.5M to 8M per minute. This precision stainless steel tube mill line is also equipped with an Ar-arc welder of 400A current intensity. In addition, the specifications of RF40 and RF60 precision stainless steel tube mill line can be directly found in the table below.
