Generally speaking, we can find two styles of pipe reducing machines: that is pipe reducing machines for industrial, and pipe reducing machines for home appliances. The industrial pipe reducing machines minaly included swaging machine, double hammer hammer roll reducing machine and rolling mill. While home appliances pipe reducing machines included SG8A, SG8B, SG12A, SG12B.

Besides, we can also find different reduced shape machines, that is square/flat shape pipe reducing machine, and round pipe reducing machine. When we need to reduced square pipes or flat pipes, usually, we need to reduce the tubes into round shape, and then reduce to square / flat shape. To reduced the pipes into square or flat shape, it need to use SDG30 double hammer roll reducing machine. However, if need to reduce the pipes into round shape, it will depend on what styles of heaters and how many need to reduce. For example, if need to make cartridge heaters, then use DG30 swaging machine will be ok.

Further more, we can find SG8A, SG8B, SG12A,SG12 B for round tube reducing. What is the difference among these pipe reducing machines? Style A pipe reducing machine will works more quite than style B. While style B tube reducing machine can reduce biger sizes tubes than style A.

Cartridge Heaters

Cartridge heater is one of the hot heaters at present. Many heater factories buy cartridge heater machines to produce cartridge heaters. So what is cargridge heaters? Here is Tubemachines.com collect introduction of cartridge heaters for you.

A cartridge heater is a thin, tube shaped heating device used to internally heat machine and process components such as platens, dies and molds, and sealing bars. The heater consists of a hollow metal tube with a wound resistive heater element embedded in an insulating compound inside it. A thermocouple or controller supplies power to the heater element via a set of leads which exit at one end of the tube. The cartridge heater is inserted into a close fitting hole in the material and, once activated, heats it from within. Cartridge heaters are available as swagged or non-swagged and in a variety of sizes and power ratings.

Machines or process parts such as embossing platens, thermoplastic molds, and extrusion dies require heating to operate correctly and, in most cases, are best heated internally. Cartridge heaters are devices commonly used to achieve this internal heating and are incorporated directly into the body of the relevant part. The cartridge heater consists of a thermally conductive metal tube, hollow at its center, and capped at one end. An electrical resistance heater element is wound around an insulating core, typically a ceramic compound, and placed into the metal tube. The space between the heater element and tube is then filled with powder such as magnesium oxide byMGO powder filling machine which insulates the element electrically but conducts heat well.

This device may then be swagged or left as-is. Swagging involves compressing the metal tube to constrict it against the powdered thermal conductor ensuring maximum heat transfer potential. Although beneficial to a point, swagging is expensive and many low cost cartridge heaters are left non-swagged. To reduce the cartridge heaters, it usually requires a swaging machine. The two heater element power supply leads exit at the uncapped end of the tube. These leads may be axial for straight line installations or radial for applications which require 90° lead orientation.

The cartridge heater is installed via a close fitting hole drilled into the heated part body. The tube needs to fit tightly into the hole to ensure maximum heater efficiency and with average manufacturer specifications requiring a 0.010 inch (0.25 mm) difference between tube and hole diameters. The output of the cartridge heater is controlled by a surface mounted thermocouple or a remote microcontroller which maintains the part at an optimal temperature. These heaters are available in a range of sizes from 1/4 inch (6.35 mm) to 1 inch (25.4 mm) in diameter. Cartridge heaters are power rated in “watt density” units based on the diameter, length, and wattage of the heater.
