Enamel coated tubes from Shandong Hengtao Energy Saving & Environment Protection are steel tubes coated with a high-temperature ceramic enamel layer designed to resist ash buildup and low-temperature corrosion in flue gas systems. These tubes are used primarily in air preheaters and heat exchangers in coal-fired power plants and industrial boilers. The base material is low-carbon steel, with enamel applied via spray and fusion processes to form a continuous, non-porous barrier.
The enamel coating is formulated to withstand temperatures up to 450°C and resist chemical attack from sulfur oxides, fly ash, and condensates. Standard tube diameters range from 30 mm to 100 mm, with wall thicknesses between 1.5 mm and 4.0 mm. The coating thickness is typically 150 to 250 micrometers, applied in two layers for durability. Unlike paint or polymer coatings, this ceramic enamel does not degrade under sustained thermal cycling.
These tubes are purchased by boiler manufacturers, power plant operators, and EPC contractors in Asia, the Middle East, and Eastern Europe. Buyers prioritize corrosion resistance and service life over initial cost. Trade terms are commonly FOB Qingdao or Tianjin, with bulk orders shipped in wooden crates. Packaging protects against mechanical damage during transit. Lead times are typically 45 to 60 days, and custom lengths can be produced upon request.
| Base material | Low-carbon steel (ASTM A53 Grade B or equivalent) |
| Typical outer diameter range | 30 mm to 100 mm |
| Typical wall thickness range | 1.5 mm to 4.0 mm |
| Enamel type | Ceramic-based, silicate-fluxed enamel |
| Coating thickness | 150 to 250 micrometers (typical) |
| Maximum continuous operating temperature | 450°C |
| Thermal shock resistance | Standard test: 5 cycles from 450°C to ambient without cracking |
| Corrosion resistance | Resists sulfuric acid condensate and fly ash abrasion per ASTM G101 |
| Typical length range | 1.5 m to 6.0 m (custom lengths available) |
| Typical packaging | Wooden crates with corner protectors, bundled by size and length |

Sourcing Enamel Coated Tubes from Shandong Hengtao Energy Saving & Environment Protection - China Import Guide
Before ordering, verify the base steel grade, enamel composition, and thermal cycling test results. Request material test reports and coating adhesion certificates per batch. Do not accept product without documented proof of corrosion resistance. For critical applications, insist on third-party inspection of sample tubes prior to shipment.
Logistics are typically handled via FOB Qingdao or Tianjin port. Lead time is usually 45 to 60 days due to coating curing and drying cycles. Payment terms are commonly 30% advance and 70% against bill of lading. Incoterms must be clearly defined; DDP may include hidden import duties. Confirm packaging method to prevent tube deformation during sea transport.
Upon arrival, inspect tubes for coating cracks, chips, or rust spots. Use a magnetic thickness gauge to verify enamel thickness at multiple points. Perform a visual inspection under UV light if the enamel contains fluorescent markers. Retain samples for independent testing of chemical resistance. Ensure documentation includes origin, material grade, coating thickness, and test results for thermal shock and adhesion.
