About Continuous Pre expander

A continuous pre expander is a device used to increase the pressure and temperature of a fluid, usually steam, before it enters an expansion turbine. The main purpose of a continuous pre expander is to improve the economy of the plant by increasing the steam temperature and pressure at the point of use. This allows for a smaller and less expensive expansion turbine to be used. A continuous pre expander can also help to reduce emissions by increasing the efficiency of the plant.

Continuous pre expanders are used to increase the diameter of metal tubing and wire prior to drawing the material through a die. The process results in a product with higher tensile strength and more consistent diameter. The increased diameter also allows for a reduction in the number of drawing operations required, which leads to increased production rates and reduced manufacturing costs.

Continuous Pre expander

1. Continuous Pre expander is a machine that is used to increase the size of metal parts.

2. The machine uses a series of rollers to increase the size of the metal part.

3. The rollers are heated so that they can expand the metal part.

4. The Continuous Pre expander is used to make the metal part larger so that it can be used in other machines.

Characteristics:

1.Inside and outside of barrel are both made of stainless steel, and the middle layer is heat preserving material.

2.With automatic material feeding system, expanding device, Japan pressure reducing valve to reduce density tolerance, drier bed and convey blower.

3.This machine can be with first and second expansion.

4.The expanded density range of foamed beads is 8~30 g/l.
