Won market trust with "high delivery, high reliability, high response"
With ISO international certification, our products are widely used in petrochemicals, aerospace, energy equipment, oil and gas pipelines, water pipelines, construction, dredging and piling engineering, and other fields, meeting the high-performance requirements of extreme working conditions. The company, with its superior quality, efficient supply chain, and customized services, exports products worldwide and has established in-depth cooperation with Fortune 500 companies and industry leaders, earning market trust with "high delivery, high reliability, and high responsiveness."
With advanced technology and strict quality control
The environmental advantages during the production process are significant. Steel pipe enterprises achieve efficient treatment of waste gas, wastewater, and solid waste by promoting ultra-low emission technologies. Waste gas treatment uses activated carbon adsorption + catalytic combustion technology, with a volatile organic compound (VOCs) removal rate of over 95%;
The company boasts superior quality, supply chain efficiency, and customized services.
The characteristics of steel pipes used in ocean engineering focus on corrosion resistance and structural strength. Seawater pipelines use super austenitic stainless steel (such as 254SMO), with chromium, molybdenum, and nitrogen content exceeding 30%. In seawater with a salinity of 3.5%, the pitting resistance equivalent (PREN) ≥40, and the corrosion resistance is more than twice that of ordinary 316 stainless steel.
