ASTM A743 CA40F Thermodynamic Steam Trap, 1 Inch, 150 LB, RF

Key Specifications / Features

The ASTM A743 CA40F Steam Trap Factory produces high-quality thermodynamic steam traps with a cast stainless steel body. These traps have a 1-inch (DN25) size and a pressure rating of Class 150 LB and PN20. They feature RF flanged ends for secure and leak-free connections. The body material is ASTM A743 CA40F, which is a corrosion-resistant alloy stainless steel, ensuring durability and reliability in various industrial applications.

The Thermodynamic Steam Traps are designed for use in steam pipelines and equipment to prevent steam leakage and eliminate condensate buildup. This helps conserve energy and prevents issues such as water hammer and other faults. Utilizing thermodynamic principles, these traps enable secondary evaporation when condensate water is discharged into a lower pressure zone. The difference in viscosity and density between steam and condensate causes the drain valve to open or close, ensuring efficient operation.

Product Features

» The working principle of the thermodynamic steam trap relies on the difference in density between vapor and liquid.
» 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. Through heat treatment and aging processes, they remain stable and wear-resistant under high temperature and high pressure, thereby enhancing the service life of the trap.
» The stainless steel heat preservation cover isolates and reduces heat loss, and prevents air locking within the trap.
» The fluid channel of the internal structure 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%.
