About Us

Leveraging 35 years of expertise to deliver reliable, customized solutions

Fujian Honglun Steel Industry Group Co., Ltd. originated from a 1991 Wenzhou steel pipe factory and was formally founded in 2019. Covering 33,000 ㎡ with 400+ staff, we hit an annual stainless steel pipe output of 60,000 tons, USD 170 million sales revenue, and hold 2,000+ tons permanent stock.

We specialize in stainless, duplex, nickel alloy, nuclear & condenser tubes plus matching pipe fittings, flanges and valves. Our product range covers OD 6–820mm, wall thickness 0.5–65mm, with maximum single length up to 36m. Supported by 25 precision rolling & cold drawing lines and 2 gas heat treatment furnaces, we adopt full-range inspection gear: ultrasonic, eddy current, X-ray flaw detectors, hydrostatic testers and spectrometers for strict quality control.

We hold pressure piping manufacturing licenses and ISO 9001/14001/45001 certifications. Our pipes serve petroleum, chemical, marine and power sectors worldwide, exported to over 20 countries including the US, South Korea and Brazil. Guided by our tenets “Pursuing Excellence, Building a Branded Enterprise” and “Converging Global Steels to Craft Stainless Excellence”, we welcome global partners for cooperation.
