What is closed in tubing head pressure in Oil and Gas industry?
usually, the tubing head is the cross-tee connected by flange both at top and bottom. The tubing head is installed on the flange of the casing head, so as to hang the tubing string and seal the annular space between the tubing string and the production casing. The tubing head is made up of the tubing head cross-tee and the tubing hanger.
How many meters of water is 1 bar?
P=rho*g*h P= pressure rho= density = 1000 kg/m^3 at about 20C g= gravitational constant on earth at sea level = 9.81 m/s^2 h= height P=1 bar=1x10^5 Pascals = 1x10^5 N/m^2 (based on the definition of the Pascal unit) since by definition 1 Newton= 1 kg*m/s^2 1x10^5 N/m^2= 1x10^5 kg*m^2/(m^3*s)= 1x10^5 kg/(m^2*s) 1x10^5 kg/(m^2*s) = 1000 kg/m^3 *9.81m/s^2 * h solving for h yields: h= 1x10^5/(1000*9.81)= 10.19367 meters This value might vary slightly due to the affect of temperature on the density of water.
What are 4 welding positions for plate welding?
flat, horizontal, vertical and over head position
What is Cold Draw Bench?
A cold draw bench is a machine that is used (or can be used) for forming metal profiles. Rollers are usually at one cnd and the head of the machine is pulled along with a chain normally. Once the material has been attached through the rollers to the head, the machine drags the material through and that's it.
What is over head position welding?
When the weld is made from under the joint.
What is suction and discharge head?
These are terms used by refrigeration and air conditioning techs. The suction is refrigerant returning to the compressor from the evaporator, or the low side. The high side is the discharge or head pressure, where high temperature high pressure gas leaves the compressor to flow into the condenser. These systems should only be worked on by licensed and experienced techs.
If compressor has faulty valves the head pressure would be?
If a compressor has faulty valves, it can lead to increased head pressure due to the inability to properly compress and discharge refrigerant. This can cause inefficiencies in the system and potentially lead to overheating of the compressor. Regular maintenance and timely replacement of faulty components are recommended to prevent further damage.
Does compressor work more efficiently with an increased head pressure?
It depends on other conditions too. There is a net suction head, which is the pressure from which the compressor is drawing the gas. An increase here will often improve the compressor's efficiency. There is also a net discharge head, which is the pressure the compressor is trying to maintain. An increase here will often decrease the compressor's efficiency. There is an efficiency curve for all compressors, and they are all different based on their design, it is dependent on the differential pressure (NDH - NSH) and load (air flow in SCFM, typically) of the compressor, at a certain load the efficiency peaks then drops as the load increases.
If a compressor has faulty valves the head pressure?
the pressure would be low
Why should you never front seat the discharge service valve while a compressor is running?
This will cause the head pressure to climb very high and if something doesn't explode or cut out on a high pressure safety, you and the equipment will be damaged. Hopefully compressor will be one with internal or external overload. To summarize DONT DO IT WHILE COMPRESSOR IS RUNNING.
Is poor compressor can cause high head pressure in an air cooled condenser?
Poor compressor performance should result in low head pressure as the system cools better than the compressor can pump.
Where is suction and discharge s?
Answer: The terms suction and discharge are the terms refer to hydraulics. In hydraulics if the the liquid has to be lifted or pumped to the usage area the hydraulic pump will be used . This pump will have to functions that is first suction to lift the fluid and the discharge or delivery . The familiar words in pair are lift and discharge; suction and discharge. The specification of pump for these terms are suction head and discharge head.AnswerThe suction pressure refers to the pressure of the referigerant being "sucked" back into the compressor. The suction pressure is a critical variable in ensuring the accuracy of the refrigerant charge, along with the tepmerature of that line as well. The "superheat", or heat added to the vapor in that line can be monitored in this manner.You have not mention which suction pressure... Actually Where ever the suction is presented that pressure is called suction pressure.... and suction pressure in practical cases normally always less that atmospheric pressure and in case of delivery pressure it is oppositeSaying that suction pressure is " the pressure of the referigerant being "sucked" back into the compressor " is not accurate.Simply , the suction pressure of a pump is the absolute pressure of a fluid , measured at the inlet of the pump ( in your answer , the pump is the compressor , and the fluid is whatever refrigerant. )The discharge pressure , is the absolute pressure of the liquid measured at the outlet of the pump.Obviously, the discharge pressure is usually bigger than suction pressure.
What does the head pressure do if the suction pressure rise?
If the suction pressure rises, the head pressure will also increase to match the rise. This is because the compressor will work harder to maintain the balance between the two pressures to ensure proper operation of the refrigeration system. A significant increase in the head pressure could lead to compressor overload or system inefficiency.
What does the amperage of a compressor do when the head pressure rises?
When the head pressure of a compressor rises, the amperage typically increases as well. This is because the compressor has to work harder to overcome the higher pressure in the system, leading to increased electrical consumption. If the head pressure continues to rise beyond normal operating conditions, it can lead to overheating and potential damage to the compressor. Thus, monitoring amperage is crucial for ensuring efficient and safe operation.
A refrigerator with a freon restriction would have what symptoms?
High head pressure; low suction pressure; overheated compressor
What causes high head pressure in a compressor?
High head pressure in a compressor can be caused by factors such as a dirty condenser coil, restricted airflow, overcharging of refrigerant, or a malfunctioning condenser fan. These issues can result in the compressor having to work harder to maintain proper pressure levels, leading to increased head pressure.
What happens to the temperature of the discharge line when the head pressure is increased?
the line go up
