ASTM A105 Thermodynamic Steam Trap, 1 IN, DN25, CL150, FNPT

Key Specifications / Features

The ASTM A105 Thermodynamic Steam Trap is a high-performance solution for steam condensate management. It features a forged carbon steel body, ensuring robustness and durability in demanding industrial environments. The 1-inch (DN25) size and pressure rating of 150 LB (PN16) make it suitable for a wide range of applications. The FNPT threaded ends provide easy installation and secure connections. Designed to efficiently remove condensate while preventing steam loss, this steam trap is ideal for maintaining system efficiency and reliability.

The Thermodynamic Steam Traps are designed for use in steam pipelines and equipment to prevent steam leakage and eliminate condensate. This helps conserve energy and prevent issues such as water hammer and other faults. By leveraging thermodynamic characteristics, secondary evaporation occurs when condensate water is discharged into a lower pressure zone. The drain valve opens or closes based on the differing viscosity and density of steam.

Product Features

» The working principle of the thermodynamic steam trap relies on the difference in vapor and liquid density.
» The valve body and bonnet are constructed from forged steel or cast steel.
» The valve clack and valve seat are made from special stainless steel. These components undergo heat treatment and aging treatment, ensuring they remain stable and wear-resistant under high temperature and high pressure conditions, thereby extending the service life of the trap.
» The stainless steel heat preservation cover isolates and reduces heat loss, preventing air locking within the trap.
» The internal fluid channel is designed in strict accordance with the Bernoulli equation, ensuring a rational and efficient structure.
» A built-in filter ensures the trap operates in a clean environment.
» The back pressure rate is as high as 80%.
