As international building safety codes become more stringent, the demand for fire sprinkler pipes that meet both UL Listing and FM Approval has grown significantly. Baolai Steel, a Chinese manufacturer established in 1991 and ranked among China’s Top 500 Manufacturers, is expanding its global supply of fire sprinkler pipes that carry this dual certification, a factor that can influence code compliance and insurance assessments for major commercial and industrial projects.
The company’s fire sprinkler pipe product line is manufactured in accordance with leading international standards, including ASTM A53, ASTM A795, and ASTM A135, as well as UL 852 requirements for metallic sprinkler pipe. The portfolio covers both Schedule 10 and Schedule 40 wall thicknesses, providing options for a range of fire suppression system designs.
“Selecting the right fire sprinkler pipe is the foundational decision in any fire suppression system,” the company stated. “Our UL and FM dual certification, combined with compliance with ASTM A53, ASTM A795, and ASTM A135, gives specifying engineers and contractors recognized product documentation for code review, project approval, and insurance assessment.”
Baolai offers fire sprinkler pipes in four primary finish types: black pipe for standard applications, hot-dip galvanized pipe with zinc coating from 30 to 100 microns for wet, dry, pre-action, and deluge systems, epoxy-coated pipe with powder epoxy from 100 to 300 microns in red RAL 3000 for high-corrosion environments, and primer-painted pipe with varnish thickness from 20 to 200 microns in various colors. All products come with flexible pipe-end options, including roll-grooved, cut-grooved, threaded, coupled, and beveled ends, and standard lengths of 5.8, 6, and 12 meters, with custom lengths available.
The company also provides deep-processing services such as grooving, threading, and customized packaging. Beyond standardized products, Baolai offers extensive customization for diameters, wall thicknesses, lengths, end finishes, surface coatings, and packaging, allowing adaptation to unique project designs and regional code variations.
Operating 13 advanced production lines with an annual capacity exceeding 5 million tons, Baolai serves customers in more than 150 countries. The company’s integrated manufacturing chain, from raw material to finished pipe, is supported by in-house laboratory testing and third-party inspection on every batch. Certifications span UL, FM, API, ASTM, JIS, EN, BS, ISO 9001, ISO 14001, and ISO 45001.
Demand patterns differ by region, from the Middle East to Southeast Asia and South America, but certified fire sprinkler pipe remains a common requirement for premium fire protection projects. Baolai’s vertically integrated production model and direct-from-factory supply chain ensure consistent quality and traceable batch control, factors critical for fire safety compliance.
Founded in 1991, Baolai Steel Group specializes in ERW welded steel pipes, fire sprinkler systems, galvanized steel pipes, and seamless steel pipes. Through its subsidiary, Tianjin Baolai International Trade Co., Ltd., the group achieves an annual export volume of approximately 150,000 tons. The company’s professional technical team provides steel selection guidance and application support, and its regular participation in international steel pipe exhibitions strengthens face-to-face partnerships with global clients.
