Introduction to API 20E fasteners

API 20E Fasteners API Spec 20E series fasteners API Spec 20E series fasteners API Spec 20E-2017-2nd Specification for Alloy and Carbon Steel Bolts for the Oil and Gas Industry, February 2017 2ND edition, effective Date: August 13, 2017These include: BSL-1 grade, BSL-2 grade, BSL-3 grade.

API Spec 20 e - 2017-2 nd "used in the oil and gas industry of alloy and carbon steel bolt specification is made by the American petroleum institute (API AmericanPetroleumInstitute English abbreviation), through many years in the field of oil and gas industry equipment manufacturing, use continuously review, standard form of special grade bolts product standards, is to bolt in the API specification or standard reference standard specification, summary, and combining with the characteristics of oil and gas industry equipment manufacture, use and release of the specialized product standards,And with the release and implementation of the 9TH edition of API SPEC Q1 Quality Management System specification.

This standard specifies technical, quality, manufacturing and documentation requirements for bolt products used in the oil and gas industry.The bolt products of different grades (BSL-1, BSL-2, BSL-3) have the comprehensive qualification requirements from raw materials, production, procurement, product manufacturing, process control, quality inspection, and final product and use, and the shipment includes the supplementary requirements that may be used by the purchaser.Especially on the basis of the original reference added to raw materials manufacturers (not the supplier) inspect the review, for the supplied product first article inspection requirements, material requirements of smelting, raw materials into a microstructure, the microstructure of the former control requirements, the machining control requirement of the product manufacture, heat treatment equipment, process control, product second after heat treatment microstructure control requirements.API Spec 20E and API Spec 20F are the world's most advanced and comprehensive product standards for dedicated fasteners for the oil and gas industry.

Manufacturers with the oil and gas industry quality management system requirements specification "API SPEC Q1 ninth edition in effect on June 1, 2014 API to manage the quality of oil and gas manufacturing enterprises, put forward the higher request, special specifications in annex A 7" manufacturing ability "specific provision: if the API that have legitimate reasons for additional review, API will likely implement additional to any subcontractor audit (fees shall be borne by the certification organization) to ensure that the organization is in conformity with the applicable API product specification and/or standards, this is the eighth edition specification does not demand.

The procurement of products (services) in the manufacturing supply chain is an important link to ensure the final quality of products.The API Spec Q1 supplement ii to the ninth edition of the Specification for Manufacturers' Quality Management System Requirements for the Oil and Gas Industry, published in June 2018, includes changes to supply chain requirements applicable to the oil and gas industry.The supplementary document will take effect on June 1, 2019.

In order to improve the reliability of the quality of products (services) in the manufacturing supply chain, API has issued API 20 series of supply chain management specifications since 2012, and provided logo certification to supply chain enterprises according to the specifications.

At present, API 20 series of supply chain product specifications that can be certified with logo include:

API Spec 20A - Carbon steel, Alloy Steel, Stainless Steel and Nickel Base Alloy Castings for the Oil and Gas Industry (August 2017, 2nd Edition)

API Spec 20B -- "Open Forgings for the Oil and Gas Industry" (April 2013, 1st Edition)

API Spec 20C -- Die Forgings for the Oil and Gas Industry (October 2015, 2nd Edition)

API Spec 20E - Alloy and Carbon Steel Bolts for the Oil and Gas Industry (February 2017, 2nd Edition)

API Spec 20F -- Anti-Corrosion Bolts for the Oil and Gas Industry (2nd Edition, May 2018)

In addition to the above product specifications for logo certification, API also publishes two supply chain service specifications:

API Std 20D -- Nondestructive Testing of Equipment for the Oil and Gas Industry (September 2013, 1st Edition)

API Std 20H -- Heat Treatment -- Batch Production Equipment for the Oil and Gas Industry (October 2015, 1st edition)

API 20E and 20F are related to the fastener industry.

This is the API to launch the first fasteners (API Spec 20 e - "used in the oil and gas industry of alloy and carbon steel bolt specification") logo product certification, API and the industry to launch a new product certification - API Spec 20 f fasteners emblem, the certification is based on published in June 2015, the first version of the API specification 20 f "used in oil and gas industry with anti-corrosion bolt specification", mainly for bolt, fastener manufacturing enterprises,It also applies to existing FASTeners such as API 6A (wellhead and tree equipment),API 16A (drillthrough equipment),API 16C (throttling and killing systems) and other petroleum equipment.

Note: API 6A ED-21, the standard API for wellhead and tree equipment, was released on November 1, 2018, formally specifying specific industry specifications for fasteners for wellhead and tree equipment.The API organization has given Chinese fastener manufacturers and users an adaptation period of 1 year to enforce API 20E and API 20F standards starting from November 1, 2019.API 6A ED-21 lists API 20E and API 20F standard fasteners as the minimum requirements compared to API 20.That is to say: since November 01, 2019, according to API 6 a ED - 21st edition production wellhead and Christmas tree equipment, must be to use the API 20 e and API 20 f certification fastener enterprises according to the requirements of standard production of fasteners (of course: the production wellhead and Christmas tree equipment enterprises do not intend to export Europe and the United States market is another matter).

Looking at the domestic valve industry, wellhead equipment, well control equipment, oil tree equipment and other enterprises, expanding the international market is the road of enterprise development and growth.The internationalization of oil and natural gas equipment and the trust of international customers on API marked products require the equipment manufacturing to be carried out in accordance with API standard, so as to ensure the quality and provide safe and reliable products.For this great opportunity, whether the fastener production enterprises or the first closed fastener use enterprises, you are ready to meet the international standards, the development of the international market?!Wish more and more Chinese enterprises can benefit from the new standard and new situation!

Are you ready for this opportunity?!A more standardized market is waiting for you and me to have great ambitions. We are looking forward to cooperating with far-sighted you hand in hand.
