1. What heat treatment services does Indotherm Engineers provide?
Indotherm Engineers provides industrial heat treatment services, including stress relieving, post-weld heat treatment, normalizing, annealing, solution annealing,
hardening, tempering, hydrogen diffusion and refractory dry-out.
2. Does Indotherm Engineers provide on-site heat treatment services?
Yes. Indotherm offers on-site heat treatment services using methods such as electrical resistance heating and internal heating with gas- or oil-fired burners,
depending on the job requirements.
3. What is post-weld heat treatment (PWHT)?
Post-weld heat treatment is a controlled heating and cooling process performed after welding to help reduce residual stresses and achieve the required metallurgical
properties in accordance with the applicable procedure and code.
4. What is stress relieving in heat treatment?
Stress relieving is a controlled thermal process used to reduce residual stresses in metal components caused by welding, fabrication or other manufacturing operations.
5. Which industries can benefit from industrial heat treatment services?
Heat treatment services can support industries such as oil and gas, petrochemicals, power generation, fertilizers, cement, heavy engineering and industrial fabrication,
depending on the component and project requirements.
6. What equipment is used for on-site heat treatment?
Equipment may include oil- or gas-fired high-velocity burners, heat treatment power sources, flexible ceramic heating pads, heating elements, temperature controllers,
thermocouples and temperature recorders.
7. Does Indotherm offer refractory dry-out services?
Yes. The company lists refractory dry-out services for industrial equipment and installations such as reformers, boilers, fired heaters, cement kilns and incinerators.
8. Can heat treatment be performed on pressure vessels and storage tanks?
Yes. The website describes heat treatment applications for pressure vessels, LPG storage bullets, Horton spheres, process columns, pipelines and other industrial
components. The suitable heating method depends on the component's dimensions, material and treatment requirements.
9. What heating methods are used for industrial heat treatment?
