Heat Treatment (PWHT)
“POWER TESTS” have a professional department capable to perform heat treatment activities for the welded joints, plates and casting including Post weld heat treatment for the welding, annealing, tempering and normalizing.
Our engineers participated in several training courses and perform thousands of heat treatment activities in refineries , power station, petrochemical plant & Prepare the work procedures according to the material type, thickness, shapes , sizes & WPS.
Evaluate the heat treatment activities depending upon the recorded (time –temperature) charts and hardness values.
PWHT Equipment high technology with different sizes and shapes of heating pads coils to cover piping, tanks, pressure vessel PWHT work with valid calibration certificates and have the required accessories such as thermo cables, insulation materials, spot weld machine …..etc. , then Perform the hardness measurement for the metal around heat treated zones , Also all safety instructions, risk analysis document, PPE, Safety instruments and signs required are documented , instructed and in place
