The details are as follows:

1. Standards are divided into three categories:

1. Petroleum equipment design and manufacturing specifications;

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

3. Recommended practices for drilling and oil production operations.

Currently, API has announced 54 product specifications that have been used for API product certification.

2. API Standardization Policy

The publication of American Petroleum Institute specifications is conducive to the procurement of standardized materials and equipment, and it is also for manufacturers to produce materials or equipment that comply with the corresponding specifications of the American Petroleum Institute. Provide guidance. These specifications are not intended to queue up the need for good technology, nor in any way prevent anyone from purchasing products produced to other specifications. The formulation and publication of API specifications and API quality outline specifications are in no way intended to restrict buyers from purchasing products from manufacturers that are not authorized to use the API monogram.

The API specification is available to anyone willing to implement the specification. The Association has made unremitting efforts to ensure the accuracy and reliability of its normative data. However, the Association does not guarantee or guarantee the publication of any API specification, and declares that API will not assume any responsibility or liability arising from any loss or damage caused by the use of API specifications.

Manufacturers who mark an API specification on their equipment or materials are responsible for complying with all terms of the specification. However, API does not make any statement, guarantee or guarantee as to whether its products actually comply with the corresponding API specifications.

3. Introduction to API Certification

1. API Monogram The API Monogram is the symbol of the American Petroleum Institute. This mark is registered in the United States and may not be used by anyone without permission.

2. API certification API certification means that through an application, inspection, and confirmation process, API will grant a certificate to a manufacturer whose product technology provider complies with API product specifications and whose quality assurance system complies with API quality outline specifications, allowing manufacturing The factory uses the API monogram on its products. The essence of API forensics is the authorization activity of trademark transfer and use.

3.API’s explanation of the monogram

(1) It is only awarded to manufacturers that have passed API certification

(2) It is not a guarantee for the manufacturer

p>

(3) It is not an endorsement of the design

(4) It is not a guarantee of the product

(5) The manufacturer guarantees that each of the confirmed products conforms to API specifications during manufacturing

(6) API recognizes that the manufacturer is trusted by API in complying with the established API standards

4. The need for API certification

API certification has changed from a potential demand in the past to an obvious demand in the process of joining the WTO. When ordering petroleum machinery products, more and more attention is paid to the quality recognition of API products due to the special status of API in the petroleum industry. Decide. API enjoys a high reputation in the United States and abroad. The petrochemical and oil production machinery technical standards it formulates are adopted by many countries. It is a petroleum machinery certification body recognized by the U.S. Department of Commerce and the U.S. Trade Commission. API's certification mark also enjoys high credibility internationally. Petroleum machinery wearing the API mark is not only considered to be of reliable quality and advanced, but of course, the price is also higher.

Companies generally report that the cost of API certification is too high. Indeed, even in developed countries in Europe and the United States, certification is a relatively high investment. From a very realistic point of view, the cost of certification is ultimately borne by the buyer, and the company's investment in certification should actually be regarded as a technical cost investment to increase the added value of the product.

When oil companies in many countries in the Middle East, South America and Asia invite bids to purchase petroleum machinery, they generally require products bearing the API mark to be eligible to participate in the bid.

API does not require mandatory laboratory testing for products applying for certification, but API has proposed 55 detailed specifications for various equipment involved in the oil and natural gas collection and processing industries. For example, the 6D specification involves pipeline valves, including ball valves, gate valves, check valves, etc.

These specifications specify the minimum requirements that a product must meet. Although there is no mandatory testing, API observers will check the product plans submitted by the manufacturer to ensure that the manufacturer implements the product specification system during the production process.
