Carbon steel fire sprinkler pipe manufactured to ASTM A53, ASTM A795, ASTM A135, and UL 852 requirements, supplied to more than 150 countries in black, galvanized, epoxy-coated, and painted finishes
TIANJIN, CHINA, August 25, 2026 -- BAOLAI, a steel pipe manufacturer established in 1991 and ranked among China's Top 500 Manufacturers, continues to strengthen its position in the global fire protection market with its UL Listed and FM Approved fire sprinkler pipe product line.
UL Listed and FM Approved Fire Sprinkler Pipe
As building safety codes tighten worldwide, fire sprinkler pipe specifications increasingly require both UL Listing and FM Approval. For major commercial and industrial projects, this dual certification can influence not only code compliance but also insurance assessment.
Baolai's fire sprinkler pipe meets this requirement across its entire product range, making it a viable choice for contractors and system integrators operating in regulated markets.
Baolai manufactures fire sprinkler pipe 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 product portfolio covers both Schedule 10 and Schedule 40 wall thicknesses.
"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."
Fire Sprinkler Pipe Finishes and Customization
Baolai's fire sprinkler pipe is available in four primary finish types:
Black fire sprinkler pipe – for standard fire protection applications
Hot-dip galvanized fire sprinkler pipe – with a zinc coating from 30 to 100 microns, suitable for wet, dry, pre-action, and deluge systems
Epoxy-coated fire sprinkler pipe – with a powder epoxy coating from 100 to 300 microns in red RAL 3000, designed for high-corrosion environments
Primer-painted fire sprinkler pipe – with a varnish thickness from 20 to 200 microns, available in black, red, blue, and customized colors
All Baolai fire sprinkler pipe products are offered with flexible pipe-end options, including roll-grooved, cut-grooved, threaded, coupled, and beveled ends. Standard lengths include 5.8 meters, 6 meters, and 12 meters, with customized lengths also available.
The company also provides deep-processing services, including grooving, threading, and customized packaging, to meet specific project requirements.
Beyond standardized products, Baolai offers extensive customization capabilities for fire sprinkler pipe, including custom diameters, wall thicknesses, lengths, end finishes, surface coatings, and packaging specifications. These capabilities allow the company to adapt its products precisely to unique project designs, regional code variations, and contractor preferences across different markets.
