ASTM A335 P9 11R SERRATED FIN TUBE oil Refining Condencer

ASTM A335 P9 11R SERRATED FIN TUBE

ASTM A335 Grade P9 is the specification for seamless ferritic alloy steel pipe designed for high temperature service. It is commonly used in power plants, refineries, etc.

Other industrial applications where high temperature and high pressure conditions exist Grade P9 provides excellent resistance to oxidation and high pressure

Temperature intensity. ASTM A-335 P9 Grade Spiral Fin Tube is made from high-quality materials and is designed to withstand extreme temperatures and pressures.

Spiral fin tube, also known as fin tube, is a heat transfer surface composed of fins wrapped around the outer surface of a base tube. Fins increase surface area

The tube area is conducive to enhancing heat transfer.

The serrated finned tube is produced using high-frequency welding technology and has high-frequency patented technology. Using high-frequency power as the heat source, the steel strip and steel pipe are heated and welded together at the same time. It has the characteristics of long life, wide operating temperature range and high voltage resistance.

Serrations are small grooves or notches cut into the surface of the fins that disrupt the boundary layer and increase turbulence in the fluid flowing through the fins. This increased turbulence enhances convective heat transfer between the pipes and fluid, resulting in a more efficient heat exchanger. Serrated finned tubes are commonly used in applications requiring high thermal performance such as boilers, air-cooled condensers and other heat exchangers.

Application

1. Enhance heat transfer efficiency: The spiral fin design increases the surface area of the tube, thereby improving the heat transfer rate and efficiency.

2. Compact size: The heat transfer efficiency is improved, and more compact heat exchangers and equipment can be designed.

3. Reduce energy consumption: The improvement of heat transfer efficiency means the reduction of energy consumption, making spiral fin tubes more cost-effective.

4. High temperature resistance: ASTM A335 Grade P9 aly-steel has excellent high temperature resistance, making the pipe suitable for harsh applications

app.

5. Corrosion resistance: P9 grade alloy steel has good corrosion resistance, ensuring the durability and service life of the spiral fin tube.

ASTM A335 Grade P9 spiral pipe applications:

- Heat exchanger: used for efficient heat exchange between two fluids in industrial processes.

. boiler. Used in power plants and industrial facilities to generate steam.

. Furnace: A high-temperature process used for heating or drying applications.

. Refinery: used in various refining processes that require high temperature resistance and efficient heat transfer.

Specific uses for ASTM A335 Grade P9 Spiral Fin Tube may vary depending on industry and application requirements.
