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

@littleinch Thank you for the feedback.

Thankyou for the feedback.@ Little Inch The pipe tape used was of brand Petro and was coated with adhesive like grease. but we had not coated this tape with polyethylene coating.The corrosion developed at the outer layer of pipe.

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 Thanks for the feedback. I don't have any other points to support the pipe. The only option is to use the purlin in the roof. I have come across Gripple support system which uses cables to support the pipe. U can find more info at www.gripple.com. But not sure how effective it...

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...

Can anyone help me in calculating friction drop in looped pipes? thanks in advance........

Hi All, Thanks very much for the response. We have decided to install isolation valves at an interval of 500 mtr and then test the pipe. The working pressure is 10 bar and will be tested at 15 bar.

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

Hi, It will be used to regulate the flow to a fountain nozzle Service fluid is water Max pressure will be 2 bar and max temp will be around 50 degree celcius (yes water temp) Water depth is 0.4 mtr Yes there is access to repair The company says it is safe to use it

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

Hi, Thank you all for the replies. Yes the pump is drawing from the bottom of the pool and we have put a screen cover over the pool (OASE suction fitting). Now it is not possible to modify the suction line as it is already casted in the concrete. I have found some TORO filters and planning...

Hi, Thanks for the reply. Yes the discharge line is vertical and is of 3" size. You suggested to install the "Y" strainer backwards. Isn't direction of flow important for "Y" strainer?

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...
