Enamelled tubes from Shandong Hengtao Energy Saving & Environment Protection are precision-manufactured steel tubes coated with a high-temperature resistant enamel layer, designed for use in air preheaters and heat exchangers. The product has a wall thickness range of 1.5 mm to 3.0 mm and an outer diameter range of 25 mm to 76 mm, consistent with standard industrial tubing dimensions. The enamel coating is applied through a continuous firing process to ensure uniform adhesion and thermal stability up to 450°C.
The base material is typically low-carbon steel, often conforming to ASTM A53 or GB/T 3091 standards, with enamel compositions based on silicate or borosilicate glass systems. These coatings provide protection against low-temperature corrosion and fly ash abrasion, common in coal-fired boiler environments. The enamel layer is non-porous and chemically inert, reducing fouling and extending service life in high-moisture, high-sulfur flue gas conditions. No surface cracking or delamination is permitted under thermal cycling tests.
These tubes are primarily purchased by power plant operators, petrochemical processors, and HVAC equipment manufacturers in Asia and Eastern Europe. Trade terms offered include FOB Qingdao and CIF destination ports, with standard packaging in steel pallets wrapped in moisture-resistant film. Minimum order quantities are typically 1 metric ton, though smaller lots may be accommodated upon request. Lead time is approximately 25 to 35 days after deposit confirmation.

Sourcing enamelled tubes from Shandong Hengtao Energy Saving & Environment Protection - China Import Guide
Before placing an order, verify the exact steel grade, enamel composition, and coating thickness with the supplier. Request copies of mill test reports for the base material and adhesion test results for the enamel layer. Confirm that the product meets the thermal and corrosion resistance requirements of your specific application, particularly if operating in high-sulfur or high-moisture environments. Do not rely on platform-generated claims without independent documentation.
Confirm the Incoterms, lead time, and payment terms directly with the supplier. Standard terms include FOB Qingdao with a 30% deposit and 70% against BL copy. Lead time is typically 25 to 35 days, but may vary with order volume and production scheduling. Ask for packaging details and whether export documentation includes commercial invoice, packing list, and origin certificate. Ensure the supplier can provide phytosanitary or non-wood packaging certification if required by your destination country.
Upon delivery, inspect the tubes for surface defects such as enamel cracks, bubbles, or peeling. Use a visual and tactile check for uniformity, and verify that the batch number matches the documentation. Conduct a simple adhesion test by lightly scratching the surface with a hardened tool; if the coating lifts, reject the batch. Retain samples for third-party testing if the order is large. Always request a quality control report signed by the supplier before final payment.
