Study of Pipe Fitting Manufacturer,Supplier and Exporter in India
Product Code : EL-FML-10023
Jlab Export is a leading Study of Pipe Fitting Manufacturer,and suppliers in India
Study of Pipe Fitting (code EL-FML-10023) is a water re-circulating bench for measuring the head lost in common pipe fittings: a ½-inch bend and elbow, a sudden expansion and a sudden contraction between 15 mm and 25 mm, a ball valve and a gate valve. Pressure tappings at the inlet and outlet of each fitting lead to a differential manometer that shows the pressure loss of that fitting alone. JLab produces this pipe-fittings loss bench in Ambala, India.

Loss Coefficient of Each Fitting
The manometer difference across a fitting gives its head loss hL in metres of water. Dividing by the velocity head in the pipe gives the loss coefficient, k = hL / (v²/2g), where v is the measured discharge divided by the pipe bore area. Taking readings at several flow rates, set with the flow control and by-pass valves, shows how steady k stays as the velocity rises.
Sudden Expansion Against Sudden Contraction
For the sudden enlargement from 15 mm to 25 mm, theory gives hL = (v1 − v2)² / 2g from the velocities in the two bores, so the measured loss can be checked against a calculated one. The contraction from 25 mm to 15 mm loses less head, because most of its loss occurs where the jet re-expands just after the vena contracta in the smaller pipe; its k is referred to the velocity in the 15 mm bore.
Head Loss and Pipe Flow Benches
- Friction in Pipe Lines Apparatus — measures straight-pipe friction in two GI pipes rather than fitting losses.
- Losses Due to Friction In Pipe Line — compares friction in four pipe materials of the same bore.
- Venturimeter and Orificemeter Calibration Set-Up — reads meter pressure differences on a differential manometer as well.
