The basic technique is the same as " trouble shooting cathodic protection systems: rectifier-ground bed "; more measurements are required, because of the multiplicity of drain points...
When the monitor, or a pipe-to-soil potential survey, indicates inadequacy of protection, the first place to look is at the protective unit. The current output of the rectifier should be check...
Each valve type has various design details that differ based on manufacturer. The following provides a brief description on types and uses of manual valves in the industry. Ball Valve is a ...
The main consideration for introducing reflux or intermediate feed into a packed tower is adequately distributing the incoming stream to the packing. Unlike most tray columns, packed towers ar...
Any liquid distributor gives some mal-distribution, because for practical reasons, liquid can only be divided into a limited number of streams. From these point sources the liquid spreads. The main ...
Perforated-pipe distributors are normally of the ladder type (spider pipe) or the perforated-ring type. Perforations are located on the underside of the pipes. The ladder type is usually easie...
Spray distributors are pipe headers with spray nozzles fitted on the underside of the pipes. They are most popular in heat transfer and scrubbing services and are infrequently used in fraction...
Guidelines for introducing liquid into parting boxes and distributor pan. In most small columns (<3 to 4 ft in diameter), the inlet pipe directly feeds the distributor pan (or trough). In ...
Orifice Steam Traps are thermostatic steam traps actuated by temperature sensitive devices, responding to changes in condensate temperature. Thermostatic steam traps respond to changes in...
Liquid or Solid Expansion Steam Traps (Wax Capsule Steam Trap) are thermostatic steam traps actuated by temperature sensitive devices, responding to changes in condensate temperature. Therm...
Bellows Steam Traps are thermostatic steam traps actuated by temperature sensitive devices, responding to changes in condensate temperature. Thermostatic steam traps respond to changes in...
Bimetallic Steam Traps are thermostatic steam traps actuated by temperature sensitive devices, responding to changes in condensate temperature. Thermostatic steam traps respond to changes...
Open Bucket Steam Traps are mechanical steam traps actuated by a float responding to changes in condensate level. Mechanical steam traps are density detectors and therefore also have diff...
Inverted Bucket Steam Traps are mechanical steam traps actuated by a float responding to changes in condensate level. Mechanical steam traps are density detectors and therefore also have ...
Closed Float Steam Traps are mechanical steam traps actuated by a float responding to changes in condensate level. Mechanical steam traps are density detectors and therefore also have dif...
