About Xuzhou Double Rings Machinery Co., Ltd - Heavy Machinery Supplier in China

China‑based Xuzhou Double Rings Machinery Co., Ltd lists five active products, all of which are coal‑fired boiler systems. The catalogue includes a Horizontal Coal Fired Boiler, the Dzl Series Steam Coal Fired Boiler, a Best Selling High Efficiency Coal Fired Boiler, a China Made Dzl Series Coal Fired Boiler, and a Best Selling Industrial Coal Fired Steam Boiler. Each entry is presented under the broader categories of Heavy Machinery, Pressure Vessels and Power Plant Spares, reflecting the company’s focus on large‑scale thermal equipment. The five boiler models cover a range of capacities typically used in power generation, district heating and industrial process steam. While the supplier’s listings do not provide HS‑code references, coal‑fired boilers generally fall under HS chapter 84 (e.g., 8419 for boiler‑type machinery). No specific certifications are claimed in the supplied data, so buyers should verify compliance with applicable standards before purchase.

Product Range and Specialties of Xuzhou Double Rings Machinery Co., Ltd

The product list comprises five distinct coal‑fired boiler designs, ranging from horizontal units to steam‑generation systems. In the global market, such boilers are commonly rated between 5 MW and 150 MW, feature water‑tube construction, and meet efficiency levels of 80‑90 % based on lower heating value. Typical industry specifications include design pressures of 2.0 - 4.0 MPa, ASME Section I or II certification, and compliance with EN 12952/12953 for European buyers. Industry practice also distinguishes high‑efficiency models that incorporate low‑NOx burners, flue‑gas recirculation and automated controls. Buyers often request data on boiler envelope dimensions, fuel consumption (kg / MWh), and emission limits (e.g., <200 mg/Nm³ SO₂). These parameters help match the equipment to plant requirements and regulatory frameworks.

Trade and Export Information - Xuzhou Double Rings Machinery Co., Ltd

Chinese manufacturers of coal‑fired boilers export primarily to power utilities and industrial plants in Southeast Asia, the Middle East, Africa and Latin America. The typical HS‑code for such equipment is 8419, which classifies “boilers, super‑heated steam generators and auxiliary plant for producing steam, other than nuclear.” Importers usually require proof of compliance with ASME, ISO 9001 quality‑management systems, and where applicable CE marking or local certification such as the Indian Bureau of Indian Standards (BIS). Logistically, boilers of the sizes listed are shipped in 20‑ft or 40‑ft containers, often with disassembly for oversized units and supplemented by on‑site erection services. Common Incoterms are FOB Chinese port (e.g., Shanghai or Tianjin) or CIF destination port, with buyers arranging inland transport and installation. Chinese export policies encourage technical documentation, test certificates and pre‑shipment inspection reports to facilitate customs clearance.

Sourcing from Xuzhou Double Rings Machinery Co., Ltd - Buyer Guidance

When sourcing from Xuzhou Double Rings Machinery Co., Ltd, buyers should request a full technical data sheet that includes rated capacity (MW), design pressure, efficiency, fuel consumption, and emission data. It is essential to obtain the boiler’s ASME stamp or equivalent certification, a recent ISO 9001 audit report, and a test report from a recognised third‑party inspection agency. Buyers should also verify the manufacturer’s after‑sale service terms, including on‑site commissioning, spare‑parts availability and warranty period. Typical minimum order quantities are one complete boiler unit, with lead times ranging from 30 to 60 days depending on capacity and customization. Packaging is usually a steel frame with protective coating, and shipping is arranged in standard containers or as break‑bulk cargo for larger units.
