Dexin Steel Tube (China) Co., Ltd. (hereinafter referred to as Dexin) was established in August 2002. It initially produced seamless steel pipes using medium-frequency hot expansion and internal boring + external turning methods. Since 2014, it has been producing high-precision seamless steel pipes for gas cylinders using cold drawing processes. Since 2017, while procuring hot-rolled steel pipes, it has utilized the production capacity of Tianhuai Steel Pipe's 508 continuous rolling mill and Wuhan Heavy Industry's 864 rolling mill to entrust billet processing, with the current annual processing volume reaching 150,000 tons. For pipes that cannot be rolled, are uneconomical, or inconvenient to produce — especially large-diameter thin-walled and ultra-thin-walled seamless steel pipes with diameters greater than 508mm and diameter-to-wall ratios greater than 25 — it uses medium-frequency hot expansion processes. Dexin currently has nine medium-frequency hot expansion production lines, capable of producing various standard, material, and specification seamless steel pipes with diameters below 1250mm, diameter-to-wall ratios up to 100, and lengths over 12 meters. The annual production capacity of hot-expanded steel pipes can reach 100,000 tons. Dexin has seven cold drawing production lines, capable of producing 60,000 tons of precision seamless steel pipes with diameters from Φ16.7 to 914mm, as well as five large lathes and deep hole boring machines, which can cold-process various high-precision large-diameter thick-walled seamless steel pipes. Dexin has become a leading seamless steel pipe manufacturer in China capable of producing both large and small diameters, with complete hot-rolled, cold-drawn, and hot-expansion processes.
Dexin is particularly strong in its powerful pipe finishing and heat treatment capabilities. It has six heat treatment furnaces (three box-type furnaces and three roller-hearth furnaces), capable of performing normalizing, tempering, annealing, and quenching on steel pipes of various diameters below Φ2400mm. It has three multi-roll straightening machines and four point straightening machines, seven internal and external polishing machines, sixteen internal and external grinding machines, phosphating, saponification, pipe end processing, UV water-based spraying, and other production equipment, as well as complete supporting physical and chemical analysis, mechanical performance, non-destructive testing, and hydrostatic testing equipment.
Dexin orders high-quality carbon steel, carbon-manganese steel, and chromium-molybdenum steel billets produced using the LD+LF+RH/VD+CCM process, effectively controlling C, P, S, and N, H, O gas content as well as the five harmful elements, ensuring the quality of steel pipes from the source while meeting the length and delivery requirements of finished pipes. It maintains year-round inventory of Φ380, Φ450, Φ500, Φ600 billets of various materials, and produces hot-rolled steel pipes of Φ273~Φ508 or larger diameters upon order. Leveraging Dexin's hot expansion, cold drawing, heat treatment, and finishing capabilities, it can flexibly and efficiently organize production to meet users' requirements for various specifications, quantities, and high-strength pipes, SSC-resistant pipes, HIC-resistant pipes, low-temperature pipes, line pipes, gas cylinder pipes, American standard pipes, and medium-low pressure pipeline materials, achieving the goal of "rapid delivery within 30 days" for urgent materials.
Dexin has successively obtained A1, A2(1), (3), B(1), (3) special equipment manufacturing licenses (pressure piping component manufacturing licenses) issued by the State Administration for Market Regulation, as well as type test reports for various materials, standards, and specifications. It has passed ISO 9001 quality management system certification, ISO 14001 environmental management system certification, OHSAS 18001 occupational health and safety management system certification, SA8000 social responsibility management system certification, Sinopec EPEC quality certification, American Petroleum Institute API 5L certification, American ASME/ASTM product certification, EU Pressure Equipment Directive PED97/23/EC certification, and has obtained qualification certifications from overseas petrochemical and power companies such as ALSTOM, FLUOR, KNPC, Brazil Petrochemical CRCC, India BHEL, Korea Samsung Heavy Industries, and Rosneft Oil.
Dexin Steel Tube (China) Co., Ltd. and Wuxi Special Steel Material Co., Ltd. operate under two brands but one management team. The former focuses on production, while the latter focuses on trade. They have a 50,000 square meter indoor warehouse with a regular inventory of 35,000 tons of steel pipes and have established long-term cooperative relationships with major domestic and international steel pipe manufacturers. They possess long-term supply capabilities and experience for petrochemical projects, and have won industry reputation and customer favor with high-quality products and services. They are qualified suppliers of alloy steel pipes and carbon steel pipes for Sinopec, members of China National Petroleum Corporation's "Energy 1", Class A material suppliers for China National Petroleum Corporation, first-level member suppliers for CNOOC, and qualified suppliers for China Coal, Sinochem, Huadian, Huaneng, CNNC, and military materials.
In response to the national "Innovation-Driven Development" strategy, Dexin attaches importance to innovation, quality improvement, and brand building. It has introduced various technical personnel, vigorously strengthened scientific research and technological innovation, and has successively obtained multiple utility model patents and invention certificates, with several invention patents. It invests no less than 20 million RMB annually for equipment renewal and upgrading. In December 2017, the group standard T/CISA002-2017 "Medium-Frequency Hot-Expanded Seamless Steel Pipes for High-Pressure Boilers" released by the China Iron and Steel Association was mainly drafted by Dexin.
In the past 10 years, Dexin has provided nearly one million tons of self-produced seamless steel pipes to more than 2,000 users in 28 countries and regions. Some pipes have been safely in service for more than 100,000 hours, with reliable quality and stable performance, earning recognition and praise from domestic and international users.
With the interpretation letter issued by the National Steel Standards Committee Steel Pipe Special Committee on July 9 this year recognizing the medium-frequency hot expansion process as continuous overall heating, in compliance with the GB/T 5310-2017 standard stating that "hot-expanded steel pipes should be formed by expanding billet steel pipes after overall heating to produce larger diameter pipes", and the upcoming revision of the GB/T 5310 standard, the doubts and obstacles for users regarding the use of medium-frequency hot-expanded steel pipes have been removed. Design institutes have also correspondingly lifted restrictions on the use of medium-frequency hot-expanded seamless steel pipes. It can be foreseen that longer and larger-diameter seamless steel pipes will be more widely used in petroleum, chemical engineering construction, and material modernization upgrades, playing a greater role.
"Striving forward for sixteen years, Dexin creates a brand", "Excellence in business, virtue in character, century-old special steel". We will adhere to the business philosophy of "Safety, Quality, Integrity, Everything for the User", uphold the commitment of "Reputation to the utmost truth, Quality to the utmost purity, Service to the utmost sincerity", and continue to provide high-quality products and services to new and old users as always. Dexin is a major seamless steel pipe manufacturer in China and is committed to becoming a world-class steel pipe supplier and service provider.
