• PWHT requirements are specified in various welding codes and standards such as ASME, AWS, and API.

Impact testing as per code is a method used to determine the toughness and resistance of materials to sudden loading.

• Impact testing is conducted to assess the behavior of materials under high-stress conditions.

• It helps in determining the ductility, brittleness, and toughness of materials.

• Common methods of impact testing include Charpy and Izod tests.

• Results of impact testing are compared to specified codes and standard...read more

The number of pressure fire lines can vary depending on the specific requirements of the system and facility.

• The number of pressure fire lines is determined by the size and layout of the facility.

• Pressure fire lines are typically installed in areas where there is a high risk of fire, such as industrial plants or commercial buildings.

• The number of pressure fire lines may also be influenced by local fire safety regulatio...read more

HVAC requirements refer to the specifications and standards needed for heating, ventilation, and air conditioning systems in a building or facility.

• HVAC requirements include proper sizing of equipment to meet the heating and cooling needs of a space

• They also involve ensuring proper ventilation to maintain indoor air quality

• Regular maintenance a...read more

The question is unclear and does not make sense. It seems to be a typo or a mistake.

• The question may be asking about a specific type of equipment or tool, but it is not clear.

• It is important to ask for clarification or more information to provide an accurate answer.

• Without more context, it is impossible to determine what 'sprlar tipe' refers to.

Types of compressors include reciprocating, rotary, centrifugal, and axial compressors.

• Reciprocating compressors use pistons to compress air or gas.

• Rotary compressors use rotating mechanisms such as screws or vanes.

• Centrifugal compressors use a rotating impeller to create centrifugal force.

• Axial compressors use rotating blades to compress air in a straight line.

• Examples include reciprocating air compressors, rotary scr...read more

The procedure to install centrifugal axial compressors involves proper planning, alignment, assembly, and testing.

• Ensure proper foundation is prepared to support the compressor

• Align the compressor with the piping system for proper flow

• Assemble the compressor components according to manufacturer's instructions

• Test the compressor for performance and efficiency before final installation

Types of pumps include centrifugal, positive displacement, and axial flow pumps.

• Centrifugal pumps: use centrifugal force to move fluid through the pump

• Positive displacement pumps: move fluid by trapping a fixed amount and forcing it through the discharge port

• Axial flow pumps: move fluid parallel to the pump shaft

A lifting plan procedure is a detailed plan outlining the steps and precautions to be taken when lifting heavy objects.

• Identify the weight and dimensions of the object to be lifted

• Determine the appropriate lifting equipment needed

• Assess the location and environment for any obstacles or hazards

• Assign roles and responsibilities to team members involved in the lift

• Communicate clearly and follow the plan step by step

• Conduc...read more

Pumps capacity refers to the maximum flow rate a pump can handle.

• Pumps capacity is typically measured in gallons per minute (GPM) or liters per minute (LPM).

• It is important to consider the required flow rate when selecting a pump for a specific application.

• Factors such as pump size, motor power, and system pressure affect the capacity of a pump.

• For example, a centrifugal pump may have a capacity of 500 GPM, while a dia
