Tensile tester is a versatile instrument designed to test a variety of materials. It consists of several types of devices used to apply controlled tensile loads to test specimens (test pieces). The tester is capable of varying the speed of load application and accurately measures the forces, strains, and elongations applied to the test piece. It is capable of carrying out many tests where load, stretch, and compression against distance are involved.

A tensile test, also known as tension test, is probably the most fundamental type of mechanical test that can perform on material. This test is simple, relatively inexpensive, and fully standardized. By pulling on something, we can very quickly determine how the material will react to forces being applied in tension. As the material is being pulled, we will find its strength along with how much it will elongate. As we continue to pull on the material until it breaks, we will obtain a good, complete tensile profile. A curve will result showing how it reacted to the forces being applied. The point of failure is of much interest and is typically called its 'ultimate strength' or UTS on the chart. This test measures the force required to break a specimen and the extent to which the specimen stretches or elongates to that breaking point. This test produces a stress-strain diagram, which is used to determine tensile modulus. The data is often used to specify a material, to design parts to withstand application force and as a quality control check of materials. Since the physical properties of many materials (especially thermoplastics) can vary depending on ambient temperature, it is sometimes appropriate to test materials at temperatures that simulate the intended end use environment.

Tensile testing machines are designed to apply a force to a material to determine its strength and resistance to deformation. These testing machines are operated at a prescribed rate of extension, and apply a uniaxial load to the specimen until the specimen ruptures. The tensile strength, elongation, initial or secant modulii, and breaking toughness are calculated from the measuring devices on the testing machine. It consists of several types of devices used to apply controlled tensile loads to test specimens. It is capable of carrying out many tests where load, stretch, and compression against distance are involved.

Tension bushings are ideal for high-load/low-speed operations in harsh, non-lubricated environments. These bushings are designed to replace solid steel (tubular) and case hardened parts. These are hollow cylinders with a full-length longitudinal slot. This slot permits compression and expansion. The bushings have chamfered ends to facilitate insertion and removal. These are roll formed from high carbon spring steel material, which has high elasticity, resilience, and wear characteristics. This process and the inherent elasticity of the material provide constant radial tension for tight fit - even if the bore hole becomes enlarged. Bushing insertion is easily accomplished either manually or with an arbor press.

Tension Floor Blocks are designed to ensure several rows of floor panels at a time are tight and in position. These are used as the return pulley for the hand line in J-guide or T-bar manual counterweight sets. These are sealed with precision ball bearings. They also have special grooves and special shoe sizes.

Tension leg platform well systems are used in drilling wellbores into the floor of an offshore body of water. This system includes buoyancy control vessel having a plurality of pull down cables attached thereto which extend to the ocean floor. A plurality of spaced apart anchors disposed at the ocean floor are positioned to receive the lower ends of the respective pull down cables.
