A, standard * * * is divided into three categories:

1. Code for Design and Manufacture of Petroleum Equipment;

2. Recommended procedures for the use and maintenance of petroleum equipment;

3. Recommended practices for drilling and oil production operations.

At present, API has published 54 product specifications for API product certification.

Second, the API standardization policy

The release of api gravity specification is conducive to the procurement of standardized materials and equipment, and also provides guidance for manufacturers to produce materials or equipment that meet the corresponding specifications of the association. These specifications are not intended to queue the demand for excellent technology, nor do they prevent anyone from buying and producing products that meet other specifications in any way. The formulation and publication of API quality standards and API quality outline quality standards is by no means to restrict buyers from buying products from manufacturers who are not authorized to use API labels.

Anyone who is willing to implement the API specification can use it. We have made unremitting efforts to ensure the accuracy and reliability of its normative data. However, the Association does not make any guarantee or guarantee for the release of any API specification, and declares that API will not bear any responsibility or obligation for the loss or damage caused by the use of API specification.

All manufacturers who indicate API specifications on their own equipment or materials have the responsibility to abide by all terms of the specifications. However, API does not make any statement, guarantee or guarantee on whether its products really meet the corresponding API specifications.

Three. Introduction to API certification

1.api logo The API logo is a symbol of API gravity. The sign is registered in the United States, and no one can use it without permission.

2.API forensics API forensics means that through the application, inspection and confirmation procedures, API grants certificates to manufacturers whose product technicians meet API product specifications and whose quality assurance system meets API quality outline specifications, allowing manufacturers to use API marks on their products. The essence of API forensics is the authorization of trademark transfer and use.

3. API description of identification

(1) only granted to manufacturers that have passed API certification.

(2) It is not a guarantee for the manufacturer.

(3) unapproved design

(4) Not a guarantee for the product.

(5) The manufacturer shall ensure that each confirmed product conforms to API specifications at the time of manufacture.

(6)API acknowledges that manufacturers are trusted by API in complying with established API standards.

Iv. requirements for API certification

API certification has changed from the potential demand in the past to the obvious demand in the process of joining WTO. In the ordering of petroleum machinery products, more and more attention is paid to the quality recognition of API products, which is determined by the special position of API in the petroleum industry. API enjoys a high reputation at home and abroad in the United States. Its technical standards for petrochemical industry and petroleum production machinery have been adopted by many countries. It is a petroleum machinery certification institution recognized by the US Department of Commerce and the US Trade Commission. The certification mark of API also enjoys a high reputation in the world. Petroleum machinery marked with API is not only considered to be reliable in quality, advanced in level, but also expensive.

Enterprises generally reflect that the cost of API certification is too high. Indeed, even in developed countries in Europe and America, certification is a high investment. From a realistic point of view, the cost of certification is ultimately borne by the buyer, and the investment of enterprises in certification should actually be regarded as the technical cost investment to improve the added value of products.

Oil companies in many countries in the Middle East, South America and Asia generally require products with API marks to be eligible for bidding when bidding for oil machinery.

The API does not require mandatory laboratory testing of products applying for certification, but it puts forward 55 detailed specifications for various equipment involved in the oil and gas collection and processing industry. For example, the 6D specification relates to pipeline valves, including ball valves, gate valves and check valves. These specifications stipulate the minimum requirements that products should meet. Although there is no mandatory inspection, API observers will check the product plan submitted by the manufacturer to ensure that the manufacturer implements the product specification system in the production process.
