Thick Cylinder Manufacturer,Supplier and Exporter in India

Thick Cylinder (Product Code: SLE/ETP/10) is a self-contained, bench-mounting stress analysis apparatus used to investigate how radial and hoop stresses and strains vary through the wall of a pressurised thick-walled cylinder, in strength-of-materials laboratories. A core item of lab equipment for technical institutes, it carries ten strain gauges inside the wall so students can compare measured strains with theory. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is the Thick Cylinder Apparatus Used For?

Hydraulic rams, high-pressure pipes and gun barrels have walls too thick for simple thin-wall formulas, because stress changes from the bore to the outside surface. Lamé's theory predicts that hoop stress is greatest at the bore and that radial stress falls from the internal pressure at the bore to zero at the outer surface. The Thick Cylinder lets students test that prediction directly.

Students raise the oil pressure in steps with the hand-pump, read the ten embedded gauges and the inner and outer wall gauges, and convert the strains to stresses. Plotting them against radius and overlaying the theoretical curves is a classic exercise in engineering lab equipment courses. Zero every gauge before pumping, let readings settle at each pressure step, and release pressure fully at the end of the session.

What to Specify When Ordering

• How you plan to read the embedded and wall-surface strain gauges, so a suitable multi-channel strain readout can be discussed.
• The number of Thick Cylinder sets required for your laboratory groups.
• Whether you also want the Thin Cylinder for comparing thin-wall and thick-wall behaviour.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Thick Cylinder apparatus. The unit is built and assembled at the company's own licensed factory at Saha, Ambala, Haryana, and supplied factory-direct to universities, engineering colleges, dealers and importers. Because the maker quotes directly, questions on set-up and later spares come straight to the people who build it. See the company profile for background.

Related Materials Testing and Properties Equipment

Apparatus often used in the same pressure-vessel and strain-measurement practicals:

• Thin Cylinder — the thin-walled counterpart, for comparing hoop and longitudinal stresses with thin-wall theory.
• Digital Strain Display — a sixteen-channel readout that gives direct strain readings from metal-foil gauges.
• Diaphragm — studies strain and deflection of a clamped diaphragm under oil pressure.
• Strain Gauge Trainer — introduces bridge circuits before students move on to pressure-vessel work.

More stress-analysis apparatus is in the Materials Testing and Properties category.

Frequently Asked Questions

What can students measure with the Thick Cylinder?
With the Thick Cylinder, students measure radial and hoop strains through the wall using ten embedded gauges, plus longitudinal and circumferential strains on the inner and outer walls, then compare the resulting stresses with thick-cylinder theory.

How are strain gauges placed inside the cylinder wall?
The Thick Cylinder is made in two halves cemented together. One face of the joint has an eccentric shallow groove holding ten strain gauges at precise radii and orientation, and jointing cement fills the groove around them.

How is the Thick Cylinder pressurised?
The Thick Cylinder contains oil. To stress the cylinder, students pressurise that oil with a hydraulic hand-pump, which lets them raise the pressure in controlled steps and take strain readings at each level.

What is the Thick Cylinder made of?
The Thick Cylinder uses a thick-walled aluminium cylinder held in a robust frame. The whole apparatus is self-contained and bench-mounting, so it can be set up on a standard laboratory bench for group practicals.

Who manufactures the Thick Cylinder?
The Thick Cylinder is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Quotations, repeat orders and spare-part requests go directly to the manufacturer.

What information helps us quote for the Thick Cylinder?
