• Where can exchangers operating pressure be found?

The nameplate The operating pressure of a heat exchanger can typically be found in its nameplate data. The nameplate is usually attached to the heat exchanger and contains key information such as manufacturer's name, model number, serial number, design temperatures and pressures, test pressure, and sometimes the materials of construction. If the nameplate is not available or readable, the information might also be found in the heat exchanger's original design specifications or in the operations manual provided by the manufacturer.

• What is the combined total weight of a 965lb channel head

and 735 lb. dollar plate?1700 pounds To find the combined total weight of the 965 lb channel head and the 735 lb dollar plate, you simply need to

add the two weights together:

965 lb (channel head) + 735 lb (dollar plate) = 1700 lb

• / 4

So, the combined total weight is 1700 pounds.

• When blinding a tower it is common practice to install

blinds?close to the tower When blinding a tower, such as a distillation tower in a refinery or chemical plant, it is common practice to install a blind flange or a spectacle blind as close to the tower as possible. This is a solid disk inserted between two flanges in a pipeline to block flow through the line. Installing it close to the tower ensures minimal process interruption and maximum safety. This method provides a safe way to isolate the tower for maintenance or safety during a shutdown. The blind should be installed on both the inlet and outlet flanges of the tower for complete isolation. Always remember to follow safety procedures when installing a blind.

• The correct tool to remove a broken pipe nipple is?

"Easy Out" The term "Easy Out" is actually a brand name that has become synonymous with the tool's function, much like "Kleenex" for tissues. The more general term for this tool is a "screw extractor" or "bolt extractor". It's used for removing broken or seized screws, bolts, studs, and in some cases, pipe fittings or nipples. The tool is designed to be driven into the object to be removed, and then turned to extract the object. 2 / 4

The exact type and size of extractor needed can depend on the specific task.

• head pressure testing is used on what type of system?

gravity flow systems Head pressure testing can be used on different types of systems, including both gravity flow systems and refrigeration or air conditioning systems.

In a gravity flow system, the head pressure, or hydraulic head, is a measure of the total fluid energy due to elevation and pressure. Testing in these systems involves assessing their ability to handle the pressure derived from the height of fluid above the point in question, crucial for systems relying on gravity like certain water supply or sewage systems.

In refrigeration or air conditioning systems, head pressure testing checks the system's ability to withstand internal pressure and helps identify potential leaks. The system is pressurized, often using its own compressor, and monitored to ensure it maintains that pressure without leakage.

In both cases, it's important to follow safety guidelines when performing these tests.

• the point of which an object is balanced when lifting is

defined as?"center of gravity." The point at which an object is balanced when lifting is defined as the "center of gravity." This is the point where all the weight of the object is evenly dispersed and all sides are in balance. Knowing the center of gravity is crucial in lifting operations to ensure stability and safety.

• 3 basic types of hitches are vertical choker and?

basket hitch The three basic types of hitches used in rigging are the vertical hitch, the choker hitch, and the basket hitch.These are different methods of attaching a load to a lifting device, each with their own specific uses and limitations.Always remember to use the appropriate hitch for the load and lifting conditions, and to follow safety guidelines.

• in oxy fuel cutting torch system what color code are the

flash back arrestors?Red&green In an oxy-fuel cutting torch system, flashback arrestors are often color-coded to prevent incorrect installation and connection of gases. Typically, the oxygen flashback arrestor is color-coded green, and the fuel gas (such as acetylene or propane) flashback arrestor is color- coded red. However, these colors can vary depending on the manufacturer, so it's always important to check the
