Different industries have their own "Norms"

The information that you need, or equipment that you wish us to select for you, needs to reflect these norms.

Unless the application is for chemical dosing, "potable water treatment", our recommendation will be for the SurgeGuard found at Shock-Guard.com, or the PumpGuard pulsation dampener for pulsation. In both cases the emphasis is in SIMPLICITY.

Beverage industry dampeners are sometimes single connection devices beingpurely used for flow fluctuation, but this provides no protection against resonance to guard heat exchangers, chillers, etc.

See PipeGuard, in single connection trim.

The liquid foods and slurries sector prefers truly flushable in place, separate in and out connection, dampeners for ease of flushing or cleaning. Please see The different levels of cleanliness.

The drug Sector prefers bolted items because they take things apart and tank them at high temperature. See Jacketed dampeners.

As most new exploration is offshore, the norm is for stainless externals. Alaska etc require low carbon metals preventing brittle fracture, quick serviceability by release from piping bases that preserve system integrity, and use of discharge system design pressures on suction dampeners - in case of blow back. All of which impact proper selection and cost. API specifications, 674, 675 etc say ASME code at a minimum.

Often the driving concern is the governmental tax grab, so that to produce profitability they can not keep slowing flow before closing stop valves.

Chemical Processing is mostly continuous, not batch. The cost of lost campaign time is extreme. High corrosion resistance, and other reliability is a premium. See how to save time, quick release methods available, see PipeHugger and FlexOrber. Flow-Thru flushability is useful before service.

Because the liquid is a lubricant, flow velocities are generally higher, up to 25 ft/sec, 7+ m/s, so the correct pipe connections are smaller. Gear, Vane, and Swash Plate pumps all run at direct driven motor speeds; so frequencies are in the 120 Hz to 250 Hz range. At these flow velocities and frequencies a single connection accumulator simply does not respond. See PistoFram by Hydrotrole
