Heat Treatment Service
GRIPCO Saudi provides professional heat treatment services for welded components, piping systems, pressure equipment, fabricated structures, and critical industrial assets. Our services are designed to support material integrity, reduce welding-induced stresses, and help achieve required mechanical and metallurgical properties through controlled thermal processing.
Post Weld Heat Treatment (PWHT)
Post Weld Heat Treatment is a controlled heating and cooling process performed after welding. It is commonly used to reduce residual stresses, control hardness, improve material stability, and support the long-term reliability of welded components.
GRIPCO Saudi provides on-site PWHT services for industrial projects, shutdown activities, fabrication yards, pipelines, pressure vessels, and process piping systems.
Our PWHT Capabilities
- Controlled heating and cooling cycles
- Temperature monitoring and recording
- Controlled soaking at specified temperatures
- Localized heat treatment of welded joints
- On-site execution at industrial facilities
- Multi-point temperature monitoring
- Heat treatment cycle documentation
- Traceability of treated welds and components
Why Heat Treatment Is Important
Welding creates localized heating and cooling that can introduce residual stresses and changes in material properties. Controlled heat treatment helps manage these effects and supports the performance of critical components.
Heat treatment can help with:
- Reduction of residual welding stresses
- Control of hardness in weld and heat-affected zones
- Improved material and dimensional stability
- Reduction of the risk of cracking
- Improved service reliability
- Compliance with project and welding requirements
Heat Treatment Process
Our heat treatment activities follow a controlled execution process.
Technical Review
The material type, weld configuration, component geometry, project specifications, and required heat treatment parameters are reviewed before execution.
Equipment Setup
Heating elements, insulation materials, thermocouples, and temperature recording equipment are installed at the required locations.
Controlled Heating
The component temperature is gradually increased according to the specified heating rate.
Soaking
The required treatment temperature is maintained for the specified holding period to achieve uniform thermal treatment.
Controlled Cooling
The component is cooled at the required controlled rate according to the approved procedure.
Documentation
Temperature charts, treatment records, and relevant documentation are maintained for traceability and project closeout.
