China Annealing Machine for Brittle Tube Material Treatment Manufacturer, Supplier, Factory
Founded in 1992, Zhaoqing Feihong Machinery & Electrical Co., Ltd specializes in full-series heating tube processing equipment manufacturing. The professional Annealing Machine for Brittle Tube Material Treatment is tailor-made for fragile, brittle metal tube workpieces formed after pipe shrinking and magnesium oxide powder filling procedures. It effectively repairs material hardening and brittleness caused by cold extrusion processing, matching perfectly with Feihong pipe shrinkers, tube filling machines and other supporting equipment to stabilize finished tube quality for industrial, civil and aerospace heating element production lines.
Targeted Processing Scene
Brittle tube materials are prone to fracture, edge cracking and micro-deformation during secondary processing, which greatly increases factory defective rate. This professional brittle tube annealing equipment is developed for such industry pain points, targeting post-forming brittle heating tube treatment.
1. Solve tube brittleness and hardening problems after cold shrinking processing
2. Repair micro-crack hidden dangers of tubes after powder filling and diameter reduction
3. Improve tube toughness to avoid explosion and fracture in bending and assembly processes
4. Adapt to high-standard brittle alloy tubes for special industrial and military use
Different from general annealing equipment, this machine focuses on toughness improvement of brittle tube materials, realizing precise and targeted heat treatment.
Core Technical Traits
Feihong Annealing Machine for Brittle Tube Material Treatment adopts mature short-circuit heating technology, with optimized parameter logic for brittle material characteristics, bringing more accurate and safer processing effects than ordinary annealing devices:
● Material adaptive annealing: Flexible switch between full-length and local annealing modes, aiming at different brittle degrees of tube materials for targeted treatment
● Gradual temperature control: 35-80KW adjustable power output, avoiding secondary damage to brittle tubes caused by excessive instantaneous temperature
● Multi-piece synchronous processing: Support 1-4 tube processing at one time, balancing high efficiency and stable treatment effect
● Custom automatic feeding: Optional automatic feeding structure reduces manual contact and avoids artificial damage to fragile brittle tubes
Standard Technical Parameters
All parameter standards of this equipment are verified and summarized through long-term brittle tube processing tests in Feihong’s 6 professional production workshops, with stable and reliable industrial application data.

Professional FAQ
Q1: Why do brittle heating tubes need professional annealing treatment instead of natural standing?
A1: Brittle tube materials produce severe internal residual stress after cold shrinking and filling forming. Natural standing cannot eliminate deep material hardening and brittleness. Feihong Annealing Machine for Brittle Tube Material Treatment uses professional short-circuit heating technology to release internal stress evenly, improve tube material toughness from the inside, and fundamentally avoid cracking and fracture in subsequent bending, assembly and use, which is an indispensable process for high-quality heating tube production.
Q2: Will the annealing process change the original tube size and precision?
A2: No. This equipment adopts low-temperature uniform stress relief annealing process for brittle tubes, focusing on improving material toughness and reducing surface hardness. It will not cause thermal deformation or size deviation of the tube body, fully retaining the precise size formed by the previous pipe shrinking process, meeting the high-precision matching requirements of industrial heating tubes.
Q3: What kinds of brittle tubes is this machine suitable for?
A3: It is suitable for all conventional metal heating tubes that become brittle and hard after shrinking and filling, including thin-wall precision tubes, special alloy tubes, hot runner heating tubes, and military-grade customized heating tubes. It supports flexible switching of full-length and local annealing modes, which can meet the brittle treatment needs of different tube materials and different defect positions.
Q4: How to improve the treatment effect for extra brittle tubes?
A4: For workpieces with extremely high brittleness, operators can adjust the equipment power within 35-80KW, extend the appropriate annealing time, and adopt segmented local annealing mode. Meanwhile, matching the optional automatic feeding structure can avoid secondary collision damage to brittle tubes during manual handling, further improving the finished product yield.
