Short Circuit Annealing Machine for Heating Tube Processing

Feihong professional factory supplies Short Circuit Annealing Machine for Heating Tube Processing, a 35-80KW industrial tube softening device solving tube brittleness and cracking after pipe shrinking process, supporting full-length & local flexible annealing with optional auto feeding assembly to optimize heating tube manufacturing production line efficiency.As a 30-year veteran Chinese heating tube full set equipment manufacturer founded in 1992, Feihong develops and produces Short Circuit Annealing Machine to match the complete heating tube production workflow, perfectly connecting pipe shrinking machines, magnesium oxide powder filling machines and tube bending equipment inside our 6 standardized factory workshops, delivering stable tube surface hardness reduction solutions for industrial & civil heating tube manufacturers worldwide.

Product Core Purpose

The Short Circuit Annealing Machine for Heating Tube Processing is specially engineered for post-shrinking heating tube heat treatment procedures, targeting the common defects of thin tube brittleness, tiny bending deformation and tube explosion risk after magnesium oxide filling and diameter reduction processing.

● Eliminate residual stress generated during tube shrinking cold forming
● Reduce metal surface hardness of finished semi-finished heating tubes
● Support two mainstream annealing modes to meet diversified production standards

This equipment belongs to the core post-processing station of Feihong integrated heating tube production line, perfectly docking FH-B3, FH-B4 series pipe shrinker machines produced in our pipe shrinking workshop.

Unique Technical Advantages

Different from ordinary tube heating furnaces in the market, this Feihong annealing equipment adopts short-circuit heating core technology, bringing multiple production advantages for heating tube factories:

1. Dual annealing mode support: Realize full-length tube annealing or segmented local annealing freely switchable based on customer product drawing requirements
2. Customizable automatic feeding module: The base 35-80KW host can be assembled with auto tube feeding structure on demand, realizing unattended continuous annealing production
3. Wide adjustable annealing length range: Adapt heating tubes from 100mm short pieces to 4000mm long industrial heating pipes without replacing internal molds
4. Multi-tube synchronous operation design: Single operation station can process 1-4 heating tubes at the same time to lift hourly output capacity
