Baolai Steel is supplying ERW pipe for infrastructure and industrial projects worldwide, leveraging an integrated system that combines manufacturing, secondary processing, inspection, and export support. The company's ERW steel pipes are utilized in oil and gas transportation, water pipelines, construction, piling, and other industrial applications. With production standards including ASTM, API, JIS, GOST, and EN, Baolai Steel offers outside diameters up to 26 inches, and specific products meet requirements such as API 5L, ASTM A53, ASTM A500, and EN 10217-1.
The company supports project-based orders with customized wall thicknesses, lengths, surface treatments, end finishes, and processing, along with required documentation. Secondary processing capabilities include hot-dip galvanizing, protective coatings, beveling, threading, grooving, cutting, marking, bending, and more. By coordinating pipe production and secondary processing within the same supply system, Baolai Steel manages more stages of an order without separating manufacturing, finishing, and inspection across multiple suppliers. This coordination is a key strength, enabling the company to handle complex project requirements efficiently.
Quality control is a critical focus. The inspection process for ERW pipe includes dimensional checks for outside diameter, wall thickness, and straightness, as well as ultrasonic or eddy current testing for weld-seam integrity and hydrostatic pressure testing for leak resistance. Each batch is inspected for quality and quantity before shipment. Buyers can request applicable test reports or third-party inspection reports, providing a clear basis for verifying that the supplied pipe matches the agreed specification. For coated or galvanized orders, inspection documentation covers coating or galvanizing requirements, giving procurement teams more than a general quality claim—they can review key dimensions, tests, and inspection records against order requirements before shipment.
This emphasis on verifiable quality is essential for international projects, where reliable production, clear specifications, and dependable supply are paramount. Baolai Steel, founded in 1991, has built its business around infrastructure, energy, construction, water transmission, and fire protection applications. The company's advantage lies in combining steel pipe manufacturing with secondary processing, inspection, technical support, and export services, creating a coordinated supply process from specification confirmation through production and shipment.
With an annual production capacity of approximately 5 million tons, Baolai Steel supports both regular distribution and larger project-based requirements. The company's broader quality and certification system includes API, JIS, ISO, UL, FM, LR, and other certifications applicable to different products and project requirements. UL and FM apply to relevant fire protection products, while API and other certifications cover their corresponding steel pipe applications. By integrating manufacturing, processing, inspection, and export capabilities, Baolai Steel continues to support customers seeking reliable steel pipe supply for long-term distribution and project procurement.
