Mobile Heat Treatment Solutions for Every Industry
Our mobile heat treatment services are trusted across multiple high-risk sectors, including
- Power Generation – Controlled heating for turbines, boilers, piping, and pressure vessels to ensure long-term performance
- Oil, Gas & Petrochemical – On-site preheating, post weld heat treatment (PWHT), and refractory dry outs for pipelines, tanks, reactors, and high-pressure systems
- Construction & Infrastructure – Supporting major builds with reliable welding preheating and heat treatment to maintain structural integrity
- Aerospace – Precision-driven heat treatment tailored to meet strict aerospace standards and customer procedures
With fully mobile units and a team of skilled engineers, we bring industrial heat treatment services directly to your site—reducing downtime, increasing efficiency, and ensuring compliance.
Pre-Heating for Welding – Why It Matters
Proper welding preheating is one of the most important steps in preventing weld failure. By raising material temperature before welding, we
- Reduce the risk of hydrogen-induced cracking
- Minimize distortion and residual stresses during cooling
- Improve weld penetration, strength, and durability
- Ensure compliance with international codes and customer specifications
Our portable pre-heating systems can be deployed directly on site, whether you’re working with small components or large industrial structures.
Post Weld Heat Treatment (PWHT) – To Customer Procedures
Post Weld Heat Treatment (PWHT) is critical for restoring mechanical properties and extending the service life of welded materials. At [Your Company Name], we carry out PWHT strictly to your procedures and industry codes.
The benefits of PWHT include
- Stress relief in welded joints
- Improved toughness, ductility, and resistance to cracking
- Extended service life in high-pressure and high-temperature environments
- Compliance with ASME, API, BS EN, and other standards
Our engineers work closely with your team to ensure every heat treatment cycle is carried out with precision and fully documented for quality assurance.
Refractory Dry-Outs – Protecting Your Assets
For furnaces, kilns, and reactors in the petrochemical, refining, and power generation industries, proper refractory dry out procedures are essential. We provide controlled heating cycles that safely remove moisture, cure refractory linings, and prevent premature cracking or spalling.
By using our on-site refractory dry-out services, you protect your equipment, reduce costly downtime, and maximize operational efficiency.
