Abstract
The utility model discloses a seamless steel tube for a high-pressure boiler. The seamless steel tube comprises a pipeline body with a hollow cross section, wherein a high-density foamed polyurethane insulation coating is wrapped on the outer wall of the hollow pipe body, wherein an anti-rust coating is arranged between the polyurethane insulation coating and the pipe body, a galvanized coating is arranged on the inner wall of the pipe body, and heat radiating holes are arranged in the outer side of the polyurethane insulation coating uniformly. The high-density foamed polyurethane insulation coating is arranged on the outer side of the seamless steel tube additionally, the effect of heat transfer of the steel tube is greatly increased; and by adopting measures such as the anti-rust coating and the heat radiating holes, the safety of the pipe body is effectively ensured. The seamless steel tube has the advantages of obtaining extremely high economic benefit, greatly increasing heat energy transfer rate of fuel, lowering production cost of enterprises, and according with the idea of low carbon, energy saving and low cost.
