Pipe Surge and Water Hammer Apparatus Manufacturer,Supplier and Exporter in India

Pipe Surge and Water Hammer Apparatus (Product Code: SLE/MCE/37) is a fluid mechanics test rig used to demonstrate pipe surge and to measure water hammer pressure transients in engineering college and polytechnic laboratories. Students work with stainless steel test pipes 3 m long and 20.2 mm in bore, a fast-acting discharge valve, electronic pressure sensors and a clear acrylic surge shaft. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of engineering lab equipment in India, at its own factory in Ambala.

What Is the Water Hammer Apparatus Used For?

When a valve at the end of a pipeline shuts quickly, the moving column of water is brought to rest and its momentum becomes a pressure wave that runs back up the pipe and reflects to and fro. On this rig students trigger that event with the fast-acting valve on the second test pipe, and the two electronic sensors capture the high-speed pressure transients as the wave travels backwards and forwards along the pipe.

Since one sensor sits beside the valve and the other half way along the pipe, the time delay between their signals gives the wave speed — the speed of sound in water, reduced by the elasticity of the metal pipe wall. The acrylic surge shaft makes the slower rise and fall of water level after a flow change visible, which links the experiment to surge tanks on hydropower and pumping mains. As lab equipment for technical institutes teaching hydraulics, it is best run with the head tank kept full and air cleared from the pipes so that repeated runs compare fairly.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of this Pipe Surge and Water Hammer Apparatus. The rig is built at the company's own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, not sourced from a trader. The company is incorporated under CIN U29309HR2020PTC087597, and the factory premises hold Factory Licence AMB-ONLINE-CHD-J-414.

Engineering colleges, universities, dealers and importers in India and international markets deal directly with the manufacturer, so questions about replacement valves, sensors or acrylic parts reach the people who build the rig — just ask us. More background is on the ScienceLab company profile.

Frequently Asked Questions

What does the Pipe Surge and Water Hammer Apparatus measure?
The Pipe Surge and Water Hammer Apparatus measures the high-speed pressure transients created when its fast-acting valve closes, using electronic pressure sensors beside the valve and half way along the 3 m test pipe. It also shows surge behaviour as a changing water level in a clear acrylic surge shaft.

How is the speed of sound in water found with this apparatus?
With the Pipe Surge and Water Hammer Apparatus, wave speed is worked out from the time delay between the two pressure sensors and their known spacing along the test pipe. The value obtained is lower than in open water, because the elastic metal pipe wall attenuates the wave.

What size are the test pipes and the surge shaft?
The test pipes of the Pipe Surge and Water Hammer Apparatus are stainless steel, 20.2 mm inside diameter and 3 m long. The surge shaft is clear acrylic with a 40 mm inside diameter and 800 mm height, and water is held in a 45 litre PVC head tank.

How much floor space does the apparatus need?
The Pipe Surge and Water Hammer Apparatus measures 3500 x 800 x 1600 mm overall and weighs 120 kg. Plan a long, level floor area with room along one side, so that students can operate the valve and watch the surge shaft and sensor readings.

How are the pressure sensor readings displayed?
The Pipe Surge and Water Hammer Apparatus picks up transients with electronic pressure sensors, but the display or data-recording arrangement offered with it should be confirmed at quotation. Please ask through the contact page which readout is supplied for your order.

Who manufactures the Pipe Surge and Water Hammer Apparatus?
The Pipe Surge and Water Hammer Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. It is supplied factory-direct to colleges, institutions, dealers and importers.

Is a calibration certificate available for the sensors?
Calibration certificate availability for the sensors on the Pipe Surge and Water Hammer Apparatus should be discussed with us before you order. State your requirement in the enquiry so that it can be answered in the quotation.
