Bending Serpentine Tube Superheater Coil ASME Standard Energy Saving

For over 30 years, Hua Dong Boiler has been consistently innovating and improving our boiler spare parts. The improvements in bending, welding and design ensure our products meet both European and American standards, ensuring a reliable performance.

Superheater Coil Description

Serpentine tube is a tube that twists and turns several times in a plane.The convection heating surface of the boiler, such as economizer, superheater and reheater, adopts the structure of serpentine tube through the belt, with horizontal and vertical layout.

The superheater, reheater and economizer of the boiler adopt serpentine tube heating surface. Due to a series of characteristics such as large number, different bending radius and many welded joints, the manufacturing process of serpentine heating surface is more complex and the productivity is lower. In recent years, in order to change this backward production appearance, China's major boiler plants have taken a series of measures in design and technology to improve the universality of product parts and components, creating necessary conditions for the mechanization, automation and organization of automatic production lines of serpentine pipe production. At present, China's major boiler plants have adopted automatic production lines with program control for the manufacture of coil heating surfaces.

1. Material composition: It is made up of snake-like tubes (carbon steel, alloy steel or heat-resistant steel, etc.) and collection boxes and other supporting material. Tubes generally have 32, 38, 42 or other types of specifications, according to user's needs separately.
2. Arrangement: vertical or horizontal layout.
3. Features: beautiful appearance, size, accuracy, first-class bending and welding technology, first-class detection equipment.

Superheater
Fossil fuel power plants often have a superheater section in the steam generating furnace.The steam passes through drying equipment inside the steam drum on to the superheater, a set of tubes in the furnace. Here the steam picks up more energy from hot flue gases outside the tubing, and its temperature is now superheated above the saturation temperature.

Reheater
Power plant furnaces may have a reheater section containing tubes heated by hot flue gases outside the tubes. Exhaust steam from the high-pressure turbine is passed through these heated tubes to collect more energy before driving the intermediate and then low-pressure turbines.
