Pipeline Accessories Applications & Usages

Air/Steam Moisture Separators

Separators are used for the removal of entrained water from steam or air.
Strainers

Strainers are used to remove dirt particles from fluid or steam and provide inexpensive protection for critical equipment such as pumps, meters, valves, traps and turbines.
Check Valves

The WSSCV is an all stainless steel in-line check valve for steam, gas or liquid service. Used in the petrochemical, pulp & paper, textile and food & beverage industries.
Drip Pan Elbow

Drip Pan Elbows are used to collect and remove condensate. Typically used on steam boilers and safety valves.
Safety Relief Valves

Safety Relief Valves are used for over-pressure protection on steam systems.

Air Vents (AV2000)
Air vents are used in steam systems for the removal of air and other non-condensable gases from process equipment, vessels and piping. Place at end of steam main and directly on process equipment.

Vacuum Breaker (WVBSS)
Vacuum breakers allow air to enter a system in order to “break the vacuum.” In a heat exchanger, the vacuum is caused by condensing steam which inhibits condensate drainage.
Drainage of liquids from storage tanks will also cause an undesirable vacuum which inhibits flow or can possibly collapse tank or vessel.

Exhaust Heads
Exhaust Heads separate entrained water from steam prior to being discharged directly to the atmosphere. Eliminates damage to rooftops and other equipment caused by hot condensate.

Flash Tanks
Flash tanks are installed in condensate return systems to vent flash steam and neutralize pressure in condensate return lines. The flash steam may be vented to atmosphere or used for low pressure heating applications.

Steam Trap Test Valve

The WSTTV Steam Trap Test Valve offers simple, immediate and visible diagnosis of any steam trap. Turning the handle 90º to the “Test” position will direct flow of steam trap out the test port for visual evaluation of discharge. This is the most effective method to inspect the function of a steam trap.

           

Air Eliminators

The AV813 and the AE1800 Series Air Eliminators are used for the removal of air and other gases from vessels or piping systems without allowing the contained liquid to escape. Air Eliminators are used only for liquid systems.

           

Suction Or Mixing Tee

The Watson McDaniel Cast Iron, Bronze or Stainless Steel Suction Tee is a specialized type of pipe fitting used for blending, agitation, recirculation, mixing, aeration and heating.

Ejectors

Watson McDaniel Ejectors perform a variety of functions depending upon the application and motive fluid (steam or water) used. See performance charts on the following pages. Applications include: exhausting, agitating, aerating, circulating, pumping and mixing.

           

Check valves can be installed on the discharge side of steam traps to eliminate backflow into the trap. With the Specially designed 1/4 PSI low cracking pressure spring. These check valves come standard on all Watson McDaniel Pressure Motive Pumps. 
Watson McDaniel Safety Relief Valves are ASME qualified for steam service and are available in Bronze and Cast Iron in 1/2” thru 6” sizes.
Test Valves can be installed downstream of any steam strap to visually inspect the discharge of condensate from the traps. Available in stainless steel up to 1" in size.
The WDF Diffuser was specifically designed to cushion the discharge from steam or air traps. They work to suppress the high velocity discharge often associated with blast-type steam traps in order to reduce noise, erosion and waterhammer. connections.
Exhaust Heads are used to separate entrained water from steam that is being vented directly into the atmosphere, preventing damage to rooftops and other equipment from hot water.
Vacuum Breakers "break the vacuum" caused by the condensing of steam or draining of liquid. These are primarily installed on the top of heat exchangers, allowing condensate to properly drain from the system
Air Vents purge unwanted air from steam systems which can inhibit the steam from entering process equipment, vessels and piping. Air vents should be placed at all high pints in the piping system  and on heat transfer equipment.
Strainers remove dirt and pipe scale from  steam systems to protect critical components such as Regulators ,Pumps and Steam Traps from damage. Available in Cast Iron , Carbon Steel and Stainless Steel up to 4' in Size.
This is a unique and specialized Product used for blending,mixing, aeration or heating by mixing steam and water together. Available in Cast Iron,Bronze and Stainless Steel
Ejectors are used for non-electric pumping of fluids or evacuating a tank or vessel of air or other gases . Used on sterilizing equipment for pre and post-evacuation of the chamber.
Air Eliminators are used on tanks or piping systems to vent air without allowing the liquid inside the tank or piping to escape. Available in Cast Iron and Stainless Steel.
Separators are used for the removal of entrained moisture in steam and compressed air lines. Separators should be placed before all regulating valves to eliminate problems caused by water  logging and wire drawing of the valve seats.
Freeze Protection Valves automatically open and discharge liquid to protect equipment from freeze damage. Scald Protection Valves automatically open and discharge overheated liquid from a system to protect personnel from possible injury due to scalding.
Drip Pan Elbows are used to collect and remove condensate. Typically used with steam safely relief valves.
Flash tanks are installed in condensate return systems to vent flash steam and neutralize pressure in condensate return lines . The flash steam may be used for low pressure heating applications or vented to atmosphere.
