Introduction of pressure vessel PED instruction:
The EU Pressure Equipment Directive was updated from 97/23 / EC to 2014/68 / EU , and the new directive has been enforced from July 2016 .
The full name of PED certification is: Pressure Equipment (PED) certification. PED is a compulsory regulation issued by EU member states to reach consensus on the safety of pressure equipment. The Pressure Equipment Directive (EDED 97/23 / EC) is a directive . Any equipment with a design pressure exceeding 0.5 bar , regardless of its pressure and volume, must meet the requirements of the PED . Equipment such as fire extinguishers, pressure gauges, valves, safety valves, air cabinets, towers, pipes, fittings, steam equipment, etc. that carry or transport fluids must comply with PED regulations.
As a result of this change, the choice of product model is as follows:
· At the Category at The at The AT at The Module at The the I = A
· At the Category II = at The Module1 at The A2, Dl, E1
· Of the Category III of The Modules The B = (Design type) + D, B (Design type) + F., B (Production type) + E, B (Production type) + C2, H
· Of The Module1 the Category IV of The B = (Production type) + D, B (Production type) + F., G, ON on Hl.
The basic requirements of PED are:
1. Safety
2. Meet the basic safety requirements of ESR ( Essential Safety Requirement ) from the aspects of design, production and testing
3. Comply with appropriate assessment procedures
4. Paste CE mark and other necessary information
PED Certified Product Range:
The PED directive is applicable tothe design, manufacture and conformity assessment of pressure equipment and complete equipment with amaximum working pressure PS greater than 0.5 bar .
Pressure equipment: It is a general term for pressure vessels, pressure pipelines, safety accessories and pressure accessories. Pressure-bearing equipment also includes components connected to the pressure-bearing part, such as flanges, piping, joints, supports, lifting ears, etc .
A section of pipe that is not yet part of a piping system is not considered a pressure device , but the same section of pipe with flanges , safety valves , elbows, etc. is considered to be a pressure device.
Pressure vessel: An enclosed space containing fluid and carrying a certain pressure.
Pressure piping: A general term for pipes that carry fluid between pressure systems. Pressure pipes can be either single pipes or piping systems consisting of pipes, fittings, expansion joints, hoses, and other pressure-bearing components.
Safety Attachment: A device used to prevent pressure equipment from exceeding permitted limits. Include:
• Direct pressure limiting devices - such as safety valves, bursting discs, yield bars, controlled safety release systems ( CSPRS )
• limiting device - a pressure switch, a temperature control valve, gauge, and safety-related control adjustment means ( the SPMCR )
Pressure-bearing accessories: Devices with certain functions and a certain pressure-bearing space.
Complete set of equipment: A combined device with overall functions, consisting of two or more pressure-bearing equipment.
Product range not covered by the PED Directive:
• Long-distance pipelines for transporting fluids or other substances between offshore or on-road facilities
• Water supply, distribution and drainage networks and their connected equipment
• 87/404 / EEC Simple Pressure Vessel Directive
• 75/324 / EEC sprayer
• Engines , steam engines , gas / steam turbines , turbine generators , pumps and transmissions
• Carbonated beverage bottles or cans for final consumption
• For liquid containers with a gas pressure above 0.5 bar
• Pressure equipment made of soft shell
• Assembly by the end user on site ( parts are PED- compliant )
Selection of I-IV equipment evaluation mode according to the latest regulations :
· At the Category at The at The AT at The Module at The the I = A
· At the Category II = at The Module1 at The A2, Dl, E1
· Of the Category III of The Modules The B = (Design type) + D, B (Design type) + F., B (Production type) + E, B (Production type) + C2, H
· Of The Module1 the Category IV of The B = (Production type) + D, B (Production type) + F., G, ON on Hl.
Apply for CE certification process:
1. Apply for a certificate according to the product confirmation
2. The two parties sign the certification contract
3. The company provides test samples and technical documents
4. Conduct sample testing and review of technical documents
5. Submit foreign audit and issue certificates to customers
6. Guidance for export use of enterprises
7. The enterprise attaches the CE mark on the product
Risk of non-compliance with CE marking
1. The risk is very large. Once investigated, it will face penalties such as fines, return of goods, destruction, and inability to clear customs. If the circumstances are serious, it will be blacklisted and permanently barred from entering the EU market.
2. In the EU market, the "CE" mark is a compulsory certification mark. Whether it is a product produced by an enterprise within the EU or a product produced in another country, it must be affixed with the "CE" mark to freely circulate on the EU market. Demonstrates that the product meets the basic requirements of the EU's New Technical Coordination and Standardization Directive. This is a mandatory requirement imposed on products by EU law.
3. The meaning of the CE mark is that the CE acronym is used to indicate that the product with the CE mark conforms to the main requirements of the relevant European directives and is used to confirm that the product has passed the corresponding conformity assessment procedure and / or the manufacturer's The declaration of conformity has truly become a passport for products to be allowed to enter the European Union market. For instructions to add CE marked products, no CE mark may not be listed for sale, has been affixed CEmark to market products that do not meet safety requirements should be ordered to withdraw from the market, continued violation of Directive CE mark requirements, Will be restricted or banned from entering the EU market or forced to withdraw from the market.
