Pipeline Auxiliaries

An accumulation of air and other non-condensible gases in pressurized liquid lines can cause a number of problems. These gases can lead to corrosion, excessive noise, reduced heat transfer, and eventually can impede or stop the liquid flow. It can cause air locks which inhibit the filling of the system or the priming of pumps. It can seriously affect the accuracy of flow measurement meters and regulating valves. Entrapped air in any water system is an enemy to thermal efficiency. It is particularly damaging in a chilled water system which does not have the natural deaeration process of hot water. Spirax Sarco float operated air and gas eliminators, when installed at points where gases collect, will quickly, efficiently, and economically purge the system.

For general cleaning and washdown applications the hosedown station is the perfect tool. Hot water is economically provided by mixing steam and cold water safely.

The removal of air from a steam system is essential for efficient operation. Air can lower the steam temperature, insulate the heat transfer surfaces, and react to form extremely corrosive acids. Spirax Sarco Thermostatic Air Vents, when installed at points where air collects, will quickly, efficiently, and economically purge the steam system. They discharge air at full bore on startup and open during normal operation whenever air collects, regardless of the steam pressure.

Spirax Sarco's range of brass radiator valves are suitable for isolation applications in steam and liquid systems. Various configurations are available including straightway, angle and offset angled.

The DCV4 provides an efffective maintenance free solution for the prevention of reverse flow in pipelines carrying most types of liquids, steam and gases. Designed to fit between two pipeline flanges, they provide a compact installation when compared size for size with conventional swing and lift type check valves.

Spirax Sarco steam injectors are designed to inject steam into tanks of water or process fluids to ensure quiet and efficient heating of the tank contents. The injector draws in cold liquid, mixes it with the steam within the injector nozzle and distributes the hot liquid throughout the tank. In many applications the circulation induced by the injector is an advantage, ensuring thorough mixing and avoiding temperature stratification.

For efficient removal of moisture from steam and gas systems. The Spirax Sarco separators provides the total solution for all pipelines carrying steam, air or gas where water particles are in suspension.

Sight glasses fitted in a fluid line provide a visual indication of the system condition. Potential problems such as blocked strainers and steam traps are all easily detectable, helping reduce inspection and maintenance time. Where reverse flow needs to be prevented, a sight check can be installed which combines a sight glass with a check valve.

Spirax Sarco vent heads are designed for fitting to vertical open-ended steam vent pipes. The vent head incorporates an internal baffle which separates entrained water from the steam, safely discharging dry steam at decreased velocity to atmosphere, protecting personnel from injury, buildings from damage and minimizing the nuisance of water spray. Simple and effective vent heads for increased safety and environmental protection.
