Tianjin Ekun Steel Group was established in 2015 and our factory is located in the biggest pipes-manufacturing base β Daqiuzhuang industrial zone in Jinghai, Tianjin, covering an area of 20,000 square meters. We operate two office locations and employ over 100 staff members.
We have built a professional organizational structure covering the whole cycle of the supply chain, including procurement, production, quality control, warehousing and transportation.
Each department operates under standardized procedures within an efficient coordination system, enabling us to deliver customized services that precisely align with client requirements β including the high-demand U.S. industrial market.
The United States is one of the world's largest consumers of spiral steel pipes, driven by massive infrastructure investments, energy sector expansion, and urban development projects. The American spiral steel pipe market is valued in the billions of dollars annually, with consistent demand from oil & gas, water infrastructure, construction, and municipal sectors.
The U.S. has over 2.6 million miles of pipeline infrastructure. Spiral steel pipes (SSAW) are critical for long-distance oil and natural gas transmission across states like Texas, Oklahoma, and North Dakota, meeting API 5L and ASTM A53 standards.
With the U.S. Infrastructure Investment and Jobs Act allocating over $1.2 trillion, demand for spiral steel pipes in bridges, tunnels, piling foundations, and structural applications has surged across states including California, New York, and Florida.
American municipalities are upgrading aging water infrastructure. Spiral steel pipes are widely used in water transmission mains, storm drainage systems, and large-diameter culverts across cities like Chicago, Houston, and Los Angeles.
Wind farm foundations and solar plant structural supports across the Great Plains and Southwest rely heavily on large-diameter spiral steel pipes. Offshore wind projects along the Atlantic Coast are creating new demand for SSAW piling pipes.
Steel mills, chemical plants, and manufacturing facilities throughout the Midwest and Gulf Coast region use spiral steel pipes extensively for fluid transport, structural columns, and process piping systems compliant with ASTM standards.
Major U.S. ports including the Port of Los Angeles, Port of Houston, and Port of New York utilize large-diameter spiral steel piling pipes for dock construction, marine foundations, and waterfront infrastructure development.
As U.S. energy and water infrastructure projects scale up, demand for large-diameter spiral submerged arc welded (SSAW) pipes continues to rise. Projects requiring pipes from 16" to 120" in diameter are increasingly common in transmission pipeline corridors.
The U.S. market enforces rigorous compliance with API 5L, ASTM A53, and AWWA C200 standards. Manufacturers supplying to American buyers must demonstrate third-party inspection, mill test reports, and full material traceability documentation.
American buyers increasingly prioritize environmentally responsible supply chains. Spiral steel pipe manufacturers are adopting cleaner production technologies, recycled steel content, and low-emission coating processes to meet U.S. ESG procurement requirements.
U.S. procurement teams are leveraging digital platforms for real-time order tracking, quality documentation management, and supply chain transparency. Leading manufacturers now offer integrated ERP-based order management and digital mill certification systems.
With aging U.S. pipeline infrastructure, demand for 3LPE, FBE-coated, and hot-dip galvanized spiral steel pipes is accelerating. These coatings significantly extend service life in harsh environments including coastal, underground, and chemical exposure conditions.
The U.S. Gulf of Mexico and Atlantic offshore energy sector is driving demand for high-strength spiral steel pipes with enhanced weld quality, dimensional precision, and pressure ratings suitable for subsea pipeline and riser applications.
Our company strictly adheres to ISO 9001 standards throughout all operations, from raw material inspection and production to product testing and related activities. Our products are manufactured in compliance with international standards including API 5L, ASTM A53/A500/A795, BS 1387/BS1139, EN39/EN 10255/EN 10219, and JIS G3444/G3466 β fully meeting U.S. procurement and engineering specifications.
They are primarily utilized in high, medium, and low-pressure fluid transportation pipelines for oil, natural gas, water, and steam, as well as in piling applications, bridges, and building structures across the United States and global markets.
To provide comprehensive one-stop solutions for our clients, we have established our own processing plants, which cover an area of 10,000 square meters. Our facilities are equipped with advanced CNC machinery and automated welding systems to meet the precision demands of U.S. engineering projects.
Our machining process services include threading for NPT and BSP, cutting, rust cleaning, painting, and export-standard packaging β all tailored to meet American project specifications and import requirements.
Our company upholds the distinguished "Ekun" corporate culture, treating every client with equal importance regardless of order size. Ekun every team member serves customers with thoughtful, warm professionalism β providing expert quotations, streamlined order processing, and attentive after-sales support. For our U.S. clients, we offer dedicated account management, time-zone-aligned communication, and full compliance documentation support.
After more than a decade of dedication and growth, our products have been exported to over 50 countries and regions worldwide, spanning Southeast Asia, the Middle East, South America, Africa, North America, and Oceania.
In the North American market β particularly the United States β our spiral steel pipes have been supplied to infrastructure contractors, energy companies, and municipal water authorities, meeting the demanding requirements of API 5L and ASTM A53 standards.
We also actively participate in international industry exhibitions to continuously expand our overseas markets and brand influence, having showcased our presence at prestigious events such as "BUILDNZ Exhibition" in New Zealand, the "Building Technology Exhibition" in Indonesia, and "OSEA Exhibition" in Singapore.
