The PED certificate and CPR certificate for seamless steel pipes are certified for different standards and needs:

1.PED certificate (Pressure Equipment Directive):
Difference: The PED certificate is a European regulation that applies to products such as pressure equipment and seamless steel pipes. It ensures that these equipment meet safety and performance standards in the European market.
Scenario: The PED certificate applies to pressure equipment and piping systems produced, sold or imported into the European market. It ensures that the product meets the legal requirements within the European Economic Area.
2.CPR certificate (Construction Products Regulation):
Difference: The CPR certificate is another European regulation that applies to construction products, including some materials and components used in construction.
Scenario: For seamless steel pipes, if these pipes are used in building structures or applications related to building safety, they may need to comply with the requirements of the CPR. The CPR certificate ensures the safety performance of the product in the construction field.
In summary, the PED certificate applies to pressure equipment and related piping systems, while the CPR certificate applies to construction materials and components, including some seamless steel pipes for specific uses. Both certificates are to ensure that the product complies with relevant legal and safety requirements in the European market.

PED Certificate (Pressure Equipment Directive)
The standards applicable to PED certificates and CPR certificates are different.

PED certificates are applicable to pressure equipment and related piping systems. Its standards usually include but are not limited to the following:

EN 10216 series standards such as EN10216-1 P235TR1; EN10216-2 P235GH; EN10216-3 P275NL1;

ASTM series standards such as ASTM A106 GrB; ASTM A106 GrC; ASTM A53 GrB; ASTM A333/A333M-18 Gr6;

EN10210 S235JRH; EN10210 S355JOH; EN10210 S355J2H
- These standards cover seamless steel pipes for pressure applications.

CPR Certificate (Construction Products Regulation)
The CPR certificate is applicable to construction materials and components. Its standards mainly include but are not limited to the following:

EN 10219 series standards EN10219 S235JRH;EN10219 S275J2H;EN10219 S275JOH;EN10219 S355JOH;EN10219 S355J2H, EN10219 S355K2H;

- These standards cover the requirements for non-alloy and fine-grained tubes for structural purposes.

EN 10210 series standards - EN10210 S235JRH;EN10210 S355JOH;EN10210 S355J2H, these standards cover the requirements for hot-formed structural steel tubes.

EN 10025 series standards - These standards cover the technical delivery conditions for hot-rolled non-alloy structural steel.EN 10255 series of standards

- These standards cover the requirements for non-alloy and alloy steels for seamless and welded steel pipes for water and other fluids.

In summary, the PED certificate applies to pressure equipment and related piping systems, while the CPR certificate applies to construction materials and components, including some seamless steel pipes for specific applications. Both certificates are intended to ensure that products meet relevant legal and safety requirements on the European marke.
