● Made of stainless steel: high degree of hardness & corrosion-proof.

A trap is called a steam trap, also known as an automatic drain or condensate drain. Divided into steam system usage and gas system usage. The trap is installed at the end of the steam heating pipeline, and its function is to continuously discharge the condensed water in the steam heating pipeline to the outside of the pipeline. Most steam traps can automatically identify steam and water (excluding constant temperature type), thereby achieving the purpose of automatic steam blockage and drainage. Drains are widely used in industries such as petrochemical, food and medicine, and power plants, playing a significant role in energy conservation and emission reduction.

When selecting a steam trap, it is not possible to simply choose from the emissions.Special attention : it is not allowed to apply trap based on the size of the pipeline. The selection needs to be based on the principles of steam trap selection and combined with the specific situation of the condensate system. In general, the selection should be based on the following aspects.

1. Select and determine the type of trap based on heating equipment and condensate discharge requirements. For heating equipment that requires fast heating speed and strict heating temperature control, it is necessary to store it in the heating equipment to avoid condensation water accumulation. As long as there is water, it must be drained. Choose a mechanical trap that can discharge saturated water. Because it is a trap that can drain water as soon as there is water, it can promptly eliminate the adverse consequences caused by water accumulation in the equipment, and quickly improve and ensure the heating efficiency required by the equipment. For heating equipment with large heating surfaces and less strict requirements for heating speed and temperature control, stagnant water can be allowed, such as steam heating drainage, process tracing pipeline drainage, etc., and thermostatic trap can be used. For medium and low pressure steam transmission pipelines, the condensed water generated in the pipeline must be quickly and thoroughly discharged, otherwise it is easy to cause water hammer accidents. The increase in moisture content in steam leads to a decrease in steam temperature, which cannot meet the process requirements of steam equipment. Therefore, mechanical traps are a good choice for medium and low pressure steam transmission pipelines.

2. Secondly, based on the working pressure and temperature of the steam equipment, determine the nominal pressure of the trap and the material of the valve body; Determine the connection and installation method of the trap. When selecting, the nominal pressure of the steam trap should not be lower than the working pressure of the steam equipment. At the same time, the material of the valve body is selected based on the nominal pressure, working temperature, and installation environment of the steam trap. Nominal pressure ≤ 1.0Mpa, using cast iron or carbon cast steel; When the nominal pressure is greater than 1.0Mpa, carbon cast steel or alloy cast steel should be selected. The working temperature of the steam trap is determined based on the steam used by the steam equipment, and the selection should not be lower than the temperature of the steam used.
