4. European Union CE certification, pressure vessel PED directive.

The CE certification mark is a safety certification mark and is regarded as a passport for manufacturers to open and enter the European market. All products affixed with the "CE certification" mark can be sold in the member states of the European Union without meeting the requirements of each member state, thus realizing the free circulation of goods within the EU member states.   

In the EU market, the "CE" mark is a compulsory certification mark. Whether it is a product produced by an EU enterprise or a product produced in another country, if you want to circulate freely on the EU market, you must affix the "CE mark to show that the product conforms to The basic requirements of the EU Directive "New Methods of Technical Coordination and Standardization". This is a mandatory requirement of EU law on products.

PED certified product range:

§ Pressure vessel: refers to a closed space containing fluid and carrying a certain pressure.

§ Pressure pipe: The general term for pipe fittings that transfer fluid between pressure-bearing systems. The pressure pipe can be a single pipe or a pipe system composed of pipes, pipe fittings, expansion joints, hoses and other pressure-bearing parts.

§ Safety accessory: A device used to prevent pressure equipment from exceeding the allowable limit. Including: direct pressure limiting devices - such as safety valves, rupture discs, yield rods, controlled safety release systems ( CSPRS ); limiting devices - pressure switches, temperature regulating valves, level gauges, and safety-related adjustment and control devices ( SPMCR )

§ Pressure-bearing accessories: devices with a certain function and a certain pressure-bearing space.

§ Complete set of equipment: a combination of two or more pressure-bearing equipment with overall functions.

6 . API certification

API is the abbreviation of American Petroleum Institute, founded in 1919, the organization is based on the characteristics of the industry and its own needs. In 1924, the API specification was formulated to provide technical specification guidance for the production of related products in the petroleum industry. As the API specifications formulated by the API organization continue to expand due to their advanced nature, versatility, safety, and the influence of the US petroleum industry in the world, the API specifications have been widely adopted by countries around the world.

API standards mainly stipulate equipment performance, sometimes including design and process specifications. Standard formulation areas include petroleum production, refining, measurement, transportation, sales, safety and fire protection, environmental regulations, etc., and its information technology standards include EDI for the oil and gas industry. Communications and information technology applications.

API enjoys a high reputation in the United States and other countries in the world. It is a petroleum machinery certification body recognized by the US Department of Commerce and the US Trade Commission. The technical standards for petrochemical and oil extraction machinery developed by it are adopted by many countries. When oil companies in the Middle East, South America and many Asian countries bid for petroleum machinery, they generally require products with the API mark to be eligible to participate in the bidding. Therefore, petroleum machinery and equipment with the API mark is not only considered to be of reliable quality but also of advanced level. Only when products enter the international market can they be accepted and trusted by users.

7 . SIL Safety Integrity Level Certification

SIL (Safety Integrity Level)-safety integrity level.

The SIL technical standard was first promulgated and formulated by the International Electro-technical Commission (IEC) and implemented under the jurisdiction of IEC/TC65. The national standardization technical committee of SIL technology is the "National Process Industry Measurement Control and Automation" Standardization Technical Committee (SAC/TC124), and the secretariat unit is the Institute of Comprehensive Technology and Economics of Machinery Industry Instrumentation.

SIL certification is divided into 4 levels: SIL1, SIL2, SIL3, SIL4, including two levels of product and system, of which SIL4 has the highest requirements.

8. Fire test certification

API 607 and API 6FA are fire resistance tests for valves 6D and 6A. Generally , API 607 is required for 6D valves that can only be rotated 90° , and API 6FA is required for others . API is the abbreviation of American Petroleum Institute. 6FA is a kind of fire protection certification for the 6A standard valve fire protection test, and there is a 607 fire protection certification for the 6D (referring to the valve that can only rotate ninety degrees).
