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

Providing a legal structure for manufacturing and selling pressure equipment into Europe, the PED certificate allows companies to trade freely across the European Union (EU) without having to go through a local approval regime in every member state.
The PED applies to the design, manufacture, and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure greater than 0.5 bar. 
The purpose of the Pressure Equipment Directive is to ensure the free flow of stationary pressure equipment within the European Union. At the same time, it is to ensure that all pressure equipment passes a high degree of safety.
According to the Community Regime of the Directive, when pressure equipment and assemblies fall above a specified pressure and volume threshold they must adhere to these requirements:
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.

After having a qualified welder, the welding procedure also needs to be certified as well. The auditor needs to see the real welding process and taking the welding current and the welding voltage as a record for the procedure. 

The final process is the facility check. The facility audit is based on ISO 9001, the quality management control plan, and the final product test. PED is required to do a 100% test of the product. Aquasky shows the ways and methods to test the product. All the documents need to be in records for 10 years. 

Aquasky has been successfully certified by TUV with PED certification since 2019.
