Total Integration Solutions For Your Pipe Making Machine/Tube Making Machine

A tube mill plan that would minimize capital equipment expenditures and would not need a lengthy machine downtime schedule to implement or repair would be ideal. Due to the current economic pressures and decreasing budgets, requirement for manufacturers to get additional productivity out of existing equipment and control systems is rising. Reliability and productivity improvements were required at tube making machine supplying as well.
When manufacturing pipes or tubes from tube mills, the effects of chemistry and melting, casting, rolling, forming, welding, sizing process and heat treating are highly complex and inter-related, therefore a pipe making machine design team with seasonal experience is important.


High-frequency contact and induction welding processes have been used in welded tube and pipe production for more than 50 years with little attention paid to the welding frequency. Choosing the most appropriate welding frequency for the particular material and thickness being welded can reduce welding defects, optimize the internal bead height, and reduce weld splatter. Using the optimum frequency for an application is especially critical when welding coated materials or when welding a variety of materials on one mill.
Yang Chen's high frequency tube making machine (tube mill) could be made with uncoiler that is single or double sided upon tube mill's size; usually model after 90 has bigger diameter and is more suitable for single uncoiler. Slitted coils are initially formed into U shape and then into a cylindrical shape with open edges using a series of forming rolls.s The horizontal accumulator, a popular accumulator in the tube mill production line and usually used for very narrow, light gauge strip and very wide strip. Horizontal accumulator operates on FIFO principle, the slitted coil is uncoiled at the entry of tube mill and the ends are sheared and welded one after another to make it a single endless strip.
Yang Chen offers various models of high frequency tube mills and its maximum thickness is up to 2.0~7.0 mm with axle of 120mm. With the maximum round tube Ø89.1~Ø220, YC-120, the square tube dimension is 80x80,150x150 with speed of 10~25m. Its space is 6*3.5*58 while machinery power is 500kw and square tubing can be made up to 150*150mm. Because of their guarantee on making qualified tube mills and also to maintain their reputable name, Yang Chen continues to use bearings from Nachi, KOYO, NSK (Japan), SKF (Germany), AC/DC motors from TECO, electric machinery from Siemens, and SNCM439 carbon steel is chosen for carbon tubing material. The tube mill uses PLC electric control system for accuracy tubes and pipes, and safer environment.

The high frequency carbon steel pipes are formed in three stages, namely forming, welding and sizing. Because welding is a sculptural process that joins materials, it has its own separate stand to avoid the shaking or disturbances from forming and sizing stages. To anneal the tube inline, an induction annealing section is typically used to heat the tube to a maximum temperature of 1,450°F. Once heated, the tube is then air cooled using a protective gas atmosphere in an after cooling line. Because of the high mill speed, the cooling section can be several hundred feet in length. Once cooled to below 800°F, the tube is then quenched in a water bath.
These tube making machines (tube mills) have servo cut system for automatic tubes that provide greater accuracy in cut length to reduce wastage. The roll is made of SKD11 tool steel, designed by AUTO CAD, and PLC touch screen control system is a simple and convenient operation system. In addition, eddy current testing machine is optional.
