This case study examines a breakthrough in steel fabrication: a more efficient method that replaces traditional Pre-Heat & Post-weld heat treating methods with a more precise heat control system. This innovation maintains consistent heat, boosts structural integrity, and protects the workpiece from damage.

THE CHALLENGE

The client plans to perform pre-heat treatment on two separate sections of a steel workpiece, positioned 30 feet apart, ensuring the temperature remains consistent throughout.

Documenting the heat treatment process is essential for quality assurance and quality control records (QAQC).

ACHIEVEMENTS

Flexible Ceramic Pads and a Twin Heat Module for pre-heat treatment enabled simultaneous heat treatment across the two separate areas.

This method ensured consistent temperature maintenance throughout the pre-heat and post-weld process.

Temperature recordings were done by the Chino Paper & Digital Recorder for QAQC purposes.

The pre-heat treatment not only enhanced the structural integrity of the steel workpiece but also streamlined the process.

FREQUENTLY ASKED QUESTIONS (FAQ)

Yes, you can specify the positioning of the magnets on the pads before placing the order. There is no extra cost for this customization.

The four built-in, high-strength limpet magnets are rated to withstand
temperatures up to 250°C (482°F) with a 35 lb pull. The magnets will begin to lose
magnetic pull at this temperature. If you require stronger magnets, please
consider our pro-series magnetic pads designed for Post Weld Heat Treatment
(PWHT).

Yes, you can. Normally, there is 2”-4” spacing between the flexible ceramic pad
and the insulation. We can adjust the insulation length or add to it based on your
requirements.

Yes, we offer technician-led on-site training for your team. Additionally, we provide
competitive online training covering maintenance and standard operating
procedures for the equipment.
