Hi All, Please let me know that the maximum pressure that a brazed copper piping of size 1 1/4" can withstand. Thanks in advance

Dear All, We have laid 1" CS Sch 40 pipe for transporting engine oil at a depth of 50 cm. The pipe was wrapped with tape and was then buried. The pipe developed corrosion within a year and now we have to replace it. Now we are planning to pour concrete in the trench then lay the pipe wrapped...

Hello All, i have read in many articles that the head of a centrifugal pump is equal to the difference of discharge and suction pressure. if so, how can we calculate the hesd for submersible pumps which are also of centrifugal type? Thanks in advance.

Dear All, I need to run a 1" Galvanized air pipe in a ware house of height 9 mtr. The pipe will be running at a height of 4 mtr from the ground. My question is regarding the supporting of this pipe. Can I use a threaded rod for a length of 5 mtr to support this pipe from the ceiling? If...

Hi All, I want to hydro test a 6" Sch 80 PVC pipe. The pipe is of 3000 mtr length with 340 no's of 2" branches. The pipe don't have any intermediate valves. The pipe is used to convey water for irrigation. Please let me know the procedure to test this pipe. Thanks in advance

Hello All, Is it ok to use Brass Gate Valve (Pegler Make) for under water applications?

Dear All, We have recently installed a Lowara pump for feeding the fountain nozzles in an outdoor application. But due to space constraint, were unable to install a strainer in the pump suction line. As the fountain is located outdoors, we are continuously facing the problem of nozzles...

Dear All, I need to install a pump having a suction size of 3". The suction is taken from a tank and because of lack of space, it is not possible to install a 3" line. So we are thinking to install 2 numbers of 2" pipe and connect them to a 3" tee and then connect to the pump. Is it feasible...

Dear All, Suppose I have a 5 storey building and air at 5 bar is needed at the 5th floor where height of each floor is 3 mtr, what should be the pressure at the compressor discharge which is placed at the ground floor? In general whether elevation plays a role in determining the discharge...

Hi All, I have installed two submersible pumps of same make and specification in a tank and connected the discharge of both of them to a common header. I want to know what will be the pressure at the header if the pump discharge pressure is 2 bar. Whether the pressure in the header remain 2...

Dear All, I would like to know what is the minimum pressure required to open a spring loaded check valve. Thanks in advance...

Dear All, I would like to know if there are any equations using which we can calculate the velocity, pressure drop and flow rate of air in pipe. Whether the same formulas used for water can be applied to air? Also please let me know whether elevation difference makes any difference to the...

Dear All, I am very much confused when to use ASTM A 53 Grade A / B / C Pipes. I know that the basic difference between various grades is in the percentage of Carbon & Magnesium if I'm not mistaken. So please help me out of this. Thanks in advance................

Hi Every one, We have recently installed 1" Chrome Ball Valve in SS pipe and the valve is connected to the pipe by means of threading. Both the pipe and valve are in water. But after a month of installation, we find rusting on the valve. Can any one please provide the reason for this...
