Huayang steel pipe was successfully delivered to ADNOC Abu Dhabi low temperature acid-resistant pipe

Recently, there is a busy and solemn scene in the production base of Hebei Huayang Steel Pipe Co., Ltd.-the first batch of low-temperature acid-resistant straight-seam steel pipes specially designed for Abu Dhabi National Oil Company (ADNOC) have been officially set off for the oil and gas project site in Abu Dhabi in the Middle East after strict intellectual construction and full-dimensional quality inspection. This is the first low-temperature and acid-resistant pipeline order that Huayang Steel Pipe has successfully passed ADNOC's strict network access certification, and it is also a milestone moment for China's high-end oil and gas steel pipe manufacturing strength to deeply cultivate the world's top energy market and practice the "Belt and Road" energy cooperation.

Entering the delivery area of Huayang steel pipe finished products, the wide factory avenue is spotless, and the staff in uniform tooling perform their duties and all the work is orderly. Several heavy flatbed trucks are arranged neatly, waiting to be loaded; The giant straight-seam steel pipes are dark and smooth, with a cold metallic luster in the sun, standing quietly in the finished product area, just like the "steel guards" who are about to go out.

The steel pipe delivered this time covers a large diameter of 762mm to 1422mm and is made of ASTM A672 and A671 CC65, which is the core product suitable for the high-end oil and gas transportation scene in the Middle East. According to the on-site staff, these pipes are specially designed for the ultra-low temperature of MINUS 46℃, and have excellent acid corrosion resistance, which can effectively resist the corrosion of acidic media such as hydrogen sulfide in oil and gas transportation, and perfectly match the strict requirements of ADNOC project on the safety and stability of pipes in extreme environments. The whole process of loading is standardized and rigorous, showing professional standards. The driving operator accurately controls and lifts the steel pipes weighing tens of tons smoothly and slowly places them on the fixed bracket of the transport vehicle; Quality inspectors check product specifications, material certificates and inspection reports one by one to ensure that each pipe meets international standards and project requirements; The logistics team is connected efficiently, and the processes of binding and reinforcement, document checking and departure registration are completed, and the whole process is orderly and efficient. "Every steel pipe carries the trust of customers, and every process is related to the reputation of China manufacturing." The person in charge of the site said that the whole process of this delivery, from production and quality inspection to loading and shipping, strictly follows international standards and ADNOC specifications to achieve zero-defect delivery, which is not only Huayang's insistence on quality, but also a solemn commitment to overseas customers.

With the loading of the last steel pipe completed, the departure instruction was issued, and the heavy truck loaded with "Made in China" slowly drove out of Huayang Factory and headed for the port. They will cross mountains and seas and arrive in Abu Dhabi, United Arab Emirates, providing core support for local oil and gas transportation projects, and also showing the world the hard-core strength and responsibility of China's high-end steel pipe manufacturing.

The Middle East is rich in oil and gas resources, but the exploitation and transportation environment is extremely harsh-some oil and gas fields are located in the alpine zone, the temperature in winter is as low as MINUS 40℃, and the oil and gas contains high acid media such as hydrogen sulfide, which puts forward almost harsh requirements for the low-temperature toughness and acid corrosion resistance of pipelines. Under this working condition, ordinary steel pipes are prone to problems such as low-temperature embrittlement and corrosion perforation, which seriously affect the safety of oil and gas transportation and the life of the project. The ASTM A672 and A671 CC65 grade pipes delivered by Huayang Steel Pipe this time are high-end products tailored for extreme working conditions in the Middle East, and their core performance has reached the international leading level:

ASTM A671 CC65 is made of a special carbon-manganese alloy, with a minimum yield strength of 65ksi(448MPa). After a special heat treatment process of quenching and tempering (Q&T), it can still maintain excellent impact toughness in the ultra-low temperature environment of MINUS 46℃, eliminating the risk of low-temperature embrittlement, and is suitable for low-temperature and high-pressure scenes such as LNG transportation and extremely cold oil and gas fields.

The product strictly follows the NACE MR0175 anti-corrosion certification standard, strictly controls the hardness of the material (≤225HB) from the raw material selection to the production process control, effectively resists stress cracking and corrosion damage caused by acidic media such as hydrogen sulfide, and is suitable for long-term service in acid oil and gas fields with high sulfur content.

Large-diameter high-pressure adaptability: It covers large-diameter specifications ranging from 762mm to 1422mm, and adopts double-sided vertical submerged arc welding process, with 100% nondestructive inspection of weld quality, high compressive strength and good sealing performance, which can meet the requirements of long-distance and large-flow oil and gas high-pressure transportation.

The products strictly follow the international authoritative standards such as ASTM (American Society for Testing and Materials) and API (api gravity), and meet ADNOC's exclusive technical specifications. From chemical composition, mechanical properties to appearance quality, nondestructive testing, all indicators have passed rigorous examination and won the authoritative recognition of the international high-end energy market.

"The ability to overcome the dual technical problems of low temperature and acid resistance stems from the continuous R&D investment and technical precipitation of Huayang Steel Pipe in the field of high-end oil and gas pipelines for many years." According to the person in charge of Huayang steel pipe technology, the company has 17 new automatic steel pipe production lines, including 3 straight seam double-sided submerged arc welded steel pipe production lines, and supporting professional anti-corrosion production lines, forming an integrated capacity of "pipe making+anti-corrosion+deep processing", which can independently develop and produce various high-end steel pipes for oil and gas, chemical industry and power, and the products are exported to more than 80 countries and regions around the world.

Abu Dhabi National Oil Company (ADNOC), as the largest state-owned energy enterprise in the United Arab Emirates, covers the whole industrial chain of oil and gas exploration and development, refining, LNG production and trade, and is a benchmark enterprise in the global energy industry. ADNOC's certification standards for suppliers are known as "extremely strict", which can be called the "strength threshold" of international high-end energy pipes. Its certification is not a simple product inspection, but a systematic evaluation throughout the whole cycle of design, manufacturing, inspection and service, covering technical document review, factory site audit, product witness testing, past performance verification and other links. Any link that does not meet the requirements will be eliminated. The core difficulty of ADNOC certification lies in the extreme requirements of product adaptability, quality stability and comprehensive strength of enterprises: on the one hand, products are required to meet the long-term service needs of complex working conditions such as high temperature, high humidity, high salt fog, low temperature and high acidity in the Middle East; On the other hand, enterprises are required to have perfect quality management system, advanced production equipment, professional technical team and rich experience in high-end project service. For a long time, ADNOC supply chain has been monopolized by international established steel pipe enterprises such as Europe, America, Japan and South Korea, and China enterprises are facing multiple challenges such as technical barriers, standard barriers and trust barriers if they want to enter their supplier system. In order to break through this barrier, Huayang Steel Pipe takes ADNOC certification as a strategic goal, sets up a professional technical and certification team, deeply studies the core documents such as ADNOC 3.1 specification, ADNOC Group projects and engineering specification for line pipe, and comprehensively benchmarks the highest international standards, from raw material procurement, production process optimization, quality control upgrade to technical service improvement, and systematically upgrades the whole chain. In the certification process, Huayang Steel Pipe has passed several rounds of rigorous audits, such as pre-examination of technical documents, on-site audit of factories, third-party witness testing of products, and performance verification. The team of ADNOC audit experts visited Huayang production base for many times, and made an all-round inspection on the automation level of production line, equipment precision, detection ability, quality management system and professional quality of employees, and conducted on-site sampling tests on the core indicators such as low-temperature toughness, acid corrosion resistance and weld quality of ASTM A672 and A671 CC65 grade pipes. After several rounds of rigorous examination and testing, Huayang Steel Pipe has successfully passed ADNOC network access certification with excellent product quality, advanced technical level, perfect management system and rich experience in high-end projects, and officially entered its global supply chain system, becoming one of the few China steel pipe enterprises that have obtained this certification. The successful acquisition of the first order indicates that Huayang Steel Pipe has reached the international first-class level in terms of technical strength, product quality and international service ability, and has the strength to compete with the world's top steel pipe enterprises on the same stage.
