Product Description

Carbon Steel /Stainless Steel Double Casing Pin Tubes Sun-Type Pin Pipe For Marine Boilers Heaters

Description of pin tube:
Pin tube exhaust gas boiler adopts pin tube to strengthen the extended heating surface of the heat transfer components, the heating surface of both sides of water pipe can be greatly increased, meanwhile the strong turbulence formed by the flue gas flowing through the surface
of pin tube can improve the heat transfer efficiency and reduce the soot accumulation,  with advantages of compact structure, high heat efficiency,  less equipment investment, and also with shock-proof, noise reduced,fouling prevented,safe and reliable features

Features of pin tube:     
Pin fin is a cantilever structure, can vibrate with impact of airflow.
The strong turbulence is formed by the flue gas between the pin tube, with strong turbulence.

Application of Spiral Fin Tubes:
Waste heat boiler tube;
Economizer tube;
Power station boiler tube;
Marine boiler tube;
Heat exchanger
