Torsion Testing Machine is system of loading which causes section of a bar or shaft to rotate about its central longitudinal axis relatively to another such section and which thus produces twist or torsion in the bar, constitutes a torsional load. The load may be composed of forces acting in any direction but the twisting or torsional affect is provided by the couples formed by these forces in planes normal to the central axis. The torsional shearing stresses in circular cross section vary from zero at the axis of the section to a maximum value at the extreme fibres. If no bending is present pure shear exists. Torsion Testing machine Consists of two independent chucks. The twist is communicated through the test piece to the other jaw on which a weighted pendulum is attached. The resistance to deflection of pendulum causes a torque to be applied to the test piece and the angles of deflection of pendulum is the measure of torque. The machine is built for maximum twisting moment at about 50 kgm. It is equipped with jaws for accomo- dating test pieces of 10 mm, 15 mm and 20 mm size either square or circular with square shoulder.

we are the leading supplier of Steel Testing Equipment. and we provide according to client requirement.

Izod Impact Testing Machine serve for determining the impact strength of notched and unnotched metal bars of different sections and different lengths according to the charpy (Beam) method. The machine is meant for making charpy, Izod and tension impact tests. The Pendulum Impact Tester is designed conducting CHARPY Izod and Impact Tension Test. The test methods conform to IS : 1757-1973 and IS :1499-1077 and IS : 1598-1977. The impact energy absorbed by the specimen during rupture is measured as the difference between the height of drop before rupture and the height of rise after rupture of the test specimen and is read on the dial scale.

We are instrumental in manufacturing, trading and supplying of high quality Twin Tensile Testing Machine. Widely used for evaluating the tensile strength of rubber, our testing machine is available with digital display of load and pulley belt system for changing speeds. In adherence with set industry norms, we only use the best quality components and sophisticated technology to design this testing machine.

Features:

• Durability

• Light weight

By keeping track of current market development, we are offering an excellent range of Tensile Testing Machine.

The main purpose of the soundness test is to assess the possible risk of late expansion due to hydration of uncombined calcium oxide and/or magnesium oxide. The test uses apparatus known as Le Chatlier apparatus, which magnifies any expansion during heating to a value that can be measured.

General Description & Specification:
The apparatus consist of a small split cylinder of spring brass or other non-corrodible metal of 0.5 mm thickness forming a mould 30 mm internal diameter and 30 mm high. On either side of the split, two indicators are brazed suitably with pointed ends made of 2 mm diameter brass wire in such a way that the distance of these ends to the centre of the cylinder is 165 mm. The split cylinder will be kept between two glass plates.

Water Bath For Le-Chatelier Test
Water bath capable of containing immersed Le-Chatlier moulds with specimens and of raising their temperature from 27' deg _ 2'deg C to boiling in 27 /- 3 minutes.
