Thin Cylinder
Thin Cylinder (Product Code: SLE/ETP/14) is a bench-mounting pressure vessel apparatus used to investigate and analyse the stresses and strains in a pressurised thin-walled cylinder, in mechanical and civil engineering laboratories. Its thin-walled aluminium cylinder sits in a robust frame that leaves it free to move along its axis, while surface strain gauges and an electronic pressure sensor record its response. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM and TVET lab equipment manufacturer in India, at its own factory in Ambala.

What Is the Thin Cylinder Apparatus Used For?
Boilers, gas bottles, water mains and aircraft fuselages are all treated as thin cylinders, where the wall is thin enough for stress to be taken as uniform through it. Simple theory then gives a hoop stress twice the longitudinal stress, and this apparatus lets students check that relationship with real measurements rather than accept it on trust.
Students pump the oil up in steps, record pressure from the gauge and electronic sensor, and read the surface strain gauges at each step. From the strain-pressure graphs they can work out hoop and longitudinal stresses and estimate the elastic constants of the aluminium, a core exercise for engineering lab equipment in India used on diploma and degree courses. Because the frame leaves the cylinder free to move along its axis, the frame itself does not add axial load. Pump slowly, let each reading settle, and release pressure fully after the test.
OEM Manufacturer
The Thin Cylinder is an original product of Jain Scientific Equipments Private Limited, which trades as ScienceLab and is its OEM (original equipment manufacturer). It is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and sold factory-direct to engineering colleges, polytechnics, dealers and importers. Quotations, repeat orders and spares questions all come straight from the manufacturer. Learn more on the ScienceLab profile.

Frequently Asked Questions
What can students work out with the Thin Cylinder?
With the Thin Cylinder, students measure surface strains at known oil pressures and use them to find hoop and longitudinal stresses, compare the results with thin-cylinder theory and estimate the elastic properties of the aluminium cylinder.
How is pressure applied and measured on the Thin Cylinder?
The Thin Cylinder contains oil that students pressurise with a hydraulic hand pump. The hydraulic pressure is measured by a gauge and by an electronic sensor, while strain gauges on the cylinder surface measure strain.
Why is the Thin Cylinder free to move along its axis?
The frame holds the Thin Cylinder so that it is free to move along its axis. This keeps the frame from adding its own axial force to the cylinder, so measured strains come from the internal oil pressure alone.
How does the Thin Cylinder differ from the Thick Cylinder?
The Thin Cylinder has a thin wall with strain gauges on its surface, suited to thin-wall theory. The Thick Cylinder has gauges embedded through a thick wall to show how radial and hoop stresses vary from bore to outside.
Who manufactures the Thin Cylinder?
The Thin Cylinder is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Buyers deal directly with the manufacturer for quotations and follow-up orders.
