What is the Pressure Equipment Directive (PED)? |Aquasky

Aquasky PED certify by TÜV Rheinland. The most important manufacturing process of the pressure tank is the welding part. There are two parts of welding that need to be certified by the welding test. The stainless steel connector welding and the tank shell circumference welding. Aquasky provides samples for each part, and the part needs to be tested by X-ray to see whether it is perfect welding without any holes. The passed sample allows the welder to get the welding qualification certification from PED.
