Creep & Stress Rupture Testing Machine RCW Series │ RCW-10~500 - Introduction HUALONG RCW Series Creep and Stress Rupture testing machine is mainly designed to perform Creep and Stress Rupture testing of a wide variety of materials to both standard and customized specifications such as ASTM E139, ISO 204, ISO/R 206 and similar international standards. These machines are capable of covering the determination of the amount of deformation as a function of time (creep test) and the measurement of the time for fracture to occur when sufficient force is present (rupture test) for materials when under constant tensile forces at constant temperature. HUALONG offers three models electronic high temperature creeptesting machine with full closed-loop servo-control in capacities from 10kN to 500kN. Applications ASTM E139 Standard test methods for conducting creep, creep-rupture and stressrupture test of metallic materials. ISO 204 Metallic materials uniaxial creep testing in tension. ISO/R 206 Creep stress rupture testing of steel at elevated temperature. Advanced servo motor and ball screw actuator which assures loading conveniently and simply. It can transfer constant rate loading to constant-load or constant stain loading automatically. Motorized draw-head assembly automatically compensates for specimen elongation and keeps loading bar with excellent load accuracy of +/- 0.5% guaranteed. Adjustable vibration isolator mounts Accessories available for a wide variety of tests. A completely enclosed robust base unit supports the lower crosshead and test actuator. This base unit houses an integral spur gear box/HTD toothed belt drive assembly, printed circuit motor & tachometer. Both room temperature and elevated temperature systems are available. Furnace and chambers available with temperature ranges from 200 to 1000 in common air Environments, and 600 to 2200 available in vacuum environment. Numerous high temperature pull rods, specimen holders, furnace systems and extensometers available for creep and stress Relaxation applications. Many of which are also adaptable to hot tensile testing applications on universal testing machines.

Why creep? The creep and rupture strength testing machine is an important equipment to determine the characteristic of metallic materials under high temperature. The significance of this instrument is more prominent especially in selecting materials for high temperature structures, increasing the reliability in estimating the life of working components, monitoring the safety of working components as well as the research and development of new materials. Creep and Stress Rupture Testing Machines Control Center High Temperature Failure Analysis Creep occurs under load at high temperature. Boilers,...

Stress Rupture Stress rupture testing is similar to creep testing except that the stresses used are higher than in a creep test. Stress rupture testing is always done until failure of the material. In creep testing the main goal is to determine the minimum creep rate in stage II. Once a designer knows the materials will creep and has accounted for this deformation a primary goal is to avoid Stress rupture time, hr Offers a comprehensive range of software products, each design in the hope of making testing simple, precise and Generation of user customized reports. Standard SPC programs for X-bar,...
