– The whole welding operations are performed by welders holding accreditation certificate based on WPS and PQR approved by the Standards Organization.
– All consumable electrodes are of the type E7018 and preheat of 300 °C, and the main welding is done with automatic submerged welding machine.
– The whole welding process is controlled by a team of quality control using methods of MT (Magnetic particles), UT (Ultrasonic), and RT (Radiography).
– After being assembled, the boiler is tested with a hydrostatic pressure equal to 1.5 times the design pressure in the presence of inspectors of the Standards Organization. It is finally insulated with at least 100 mm thick rock wool and coated with stainless steel with a minimum thickness of 1 mm.
– All consumables and manufacturing processes are inspected by companies holding certificate of technical inspection of boilers. After controlling their quality, Iran national standard plate and inspection booklet are finally issued.
– With corrugated furnace.
– With manhole and headhole for visiting inside the boiler and handholes for sediment removal.
