04.Eu CE certification, pressure vessel PED directive

The CE mark is a security certification mark that is seen as the manufacturer's passport to open and enter the European market.All products affixed with the "CE certification" mark can be sold in the eu member states without meeting the requirements of each member state, thus realizing the free circulation of goods in the eu member states.

In the eu market, the "CE" mark is a mandatory certification mark. No matter the product produced by the enterprise within the eu or the product produced by other countries, the "CE" mark must be added to indicate that the product conforms to the basic requirements of the directive of the eu "new method of technical coordination and standardization" in order to circulate freely in the eu market.This is a mandatory product requirement under eu law.

PED certified product range:

Pressure vessel: a confined space containing fluid and bearing a certain amount of pressure.Pressure piping: general term for pipe fittings used to transfer fluid between pressure systems.Pressure piping may be either a single pipe or a system of pipes, fittings, expansion joints, hoses, and other pressure components.Safety accessories: device used to prevent pressure equipment from exceeding the allowable limit.Include: direct pressure limiting devices such as safety valves, bursting discs, yield rods, controlled safety release systems (CSPRS);Limiting devices - pressure switches, temperature control valves, level gauges, and safety-related control devices (SPMCR) pressure accessories: devices with certain functions and certain pressure Spaces.Complete set of equipment: composed of two or more pressure equipment, with the overall function of the combination of equipment.

05.Cu-tr customs union

In order to make it easier for Union trade between countries, also in order to avoid in the import and export products within the Customs Union's barriers to Technical Regulations, the Customs Union legislation mandatory Customs Union TR Technical Regulations issued certificate, certificate of the Customs Union Customs Union Technical Regulations certificate: to prove the product conforms to the Customs Union of Technical Regulations only prove that the certificate is suitable for: Russia, belarus, kazakhstan across.

06.API certification

The API, which stands for the American Petroleum Institute, was created in 1919 as an organization tailored to the industry's characteristics and needs.In 1924, API specification was established to guide the production of oil industry related products.API specifications formulated by the API organization have been widely adopted by countries around the world due to their advanced nature, versatility, safety and the growing influence of the American oil industry in the world.

API standards mainly prescribe equipment performance and sometimes include design and process specifications. The standard formulation area includes petroleum production, refining, measurement, transportation, sales, safety and fire protection, environmental regulations, etc. Its information technology standards include EDI for oil and gas industry, communication and information technology application, etc.

API enjoys a high reputation in the United States and around the world. It is recognized by the U.S. department of commerce and the U.S. trade commission as a certification body for petroleum machinery.The technical standards of petrochemical and oil extraction machinery formulated by it have been adopted by many countries. When oil companies from many countries in the Middle East, South America and Asia bid for petroleum machinery, they generally require products bearing API marks to be eligible to participate in the bidding.Therefore, with the API logo of petroleum machinery equipment is not only considered to be reliable quality and advanced level, the product into the international market for users to accept and trust.

07.SIL safety integrity level certification

SIL (Safety Integrity Level) - Safety Integrity Level.

SIL technical standards were first promulgated and formulated by the international electrotechnical commission (IEC) and implemented centrally by IEC/TC65.The national technical committee on SIL technology is the national technical committee on process industrial measurement control and automation (SAC/TC124), and the secretariat is the institute of comprehensive technical and economic research of instruments and instruments for the mechanical industry.

The SIL certification is divided into four levels: SIL1, SIL2, SIL3 and SIL4, including the product and system levels, among which SIL4 has the highest requirements.

08.Fire test certification

API 607 and API 6FA are fire resistance tests for valve 6D and 6A. Generally, only a 6D valve rotating 90° needs to be done API 607, while others need to be done API 6FA.PAI is short for American petroleum institute,6FA is a kind of fire protection certification for 6A standard valve fire test, and a 607 fire protection certification for 6D standard valve fire test

API 607-2010 fire resistance test for 1/4 cycle valves and non-metallic seat valves

The Fire Test for Quarter - Turn Valves and Valves Equipped with Nonmetallic seats.

10.ATEX explosion proof certification

The European explosion protection directive ATEX(94/9/EC) has been enforced since 1 July 2003.This instruction is applicable to both electrical and non-electrical equipment, including all kinds of explosion-proof electrical equipment, protection systems, safety instruments, control instruments and regulating devices.

Core requirements of ATEX explosion-proof instruction:

To protect the safety and health of people and, in certain circumstances, the health and property of livestock, particularly workers from the hazards of equipment and systems suitable for potentially explosive environments.

Manufacturers wishing to enter Europe and sell explosive products in Europe must demonstrate that their products comply with the ATEX directive 2014/34/EU.

There are three preconditions for the application of this instruction:

1. The equipment must have its own ignition source;

2. Expected to be used in potentially explosive environments (air mixtures);

3. Under normal atmospheric conditions.

The directive also applies to components necessary for safe use and, where applicable, to safety devices directly beneficial to the safe use of equipment.These devices can be exposed to potentially explosive environments.
