MINIATURE TESTING SERIESSUBMILLI TEST
Residual life evaluation of power plant components has been conventionally conducted by using nondestructive or mechanical methods that require fairly large samples extracted from the components. A recently developed mechanical method is the one that uses an approx. 2 mm diameter miniature specimen, which will minimize the effect to the components and is less expensive. KMTL has been conducting research and development for the methods and machines using an even smaller 1 mm diameter specimen, receiving good reputation from domestic and international suppliers.
ON-SITE SAMPLING USING EDSE
In all industries such as the electric power industry using thermal power generation, evaluating residual life and ensuring reliability and health of operating plants are important international issues. Our unique Electric Discharge Equipment (EDSE) aids in periodic maintenance and other inspections at the sites of the plants through sample extraction, as required by the customer, as well as in removal of the defective or deteriorated parts of components.
KMTL’s on-site sampling
① uses Electric Discharge Sampling Equipment developed by our company,
② takes samples directly from plant components (Sample thickness: 2.5 mm),
③ shortens time required to extract a sample (Standard time for taking a sample: 2 - 3 hours),
④ includes scaffolding and curing (Normal work period: 1 week),
⑤ requires no big work, extracting a small sample,
⑥ is available at low cost utilizing the equipment and excellent staff,
⑦ can be conducted at any place for any part, and
⑧ causes little adverse effect on facilities and components.

SMALL PUNCH CREEP TESTING EQUIPMENT
KMTL, jointly with Kyushu Electric Power Co., Inc., has developed the world’s most compact-sized and lightweight Small Punch Creep Testing Machine. This equipment enables creep testing to evaluate material deterioration with minimum amount of samples.
Non-destructive and destructive testing methods are used to evaluate heat-resisting members of high-temperature and high-pressure components in thermal power generation facilities, and, however, they conventionally require, for example, a 6-mm diameter bar specimen that significantly affects the component to be sampled. This equipment uses a miniature specimen (a disk 8-mm in diameter and 0.5 mm in thickness) machined from a sample material scooped from piping for residual life evaluation.
This development was highly regarded and won awards from The Japan Society of Mechanical Engineers Kyushu Branch and Thermal and Nuclear Power Engineering Society Kyushu Branch.
The small punch creep test is a type of miniature testing that obtain creep properties using a test specimen smaller than a one dime coin. For diagnosing the level of aging and deterioration of power generation equipment including boilers, creep testing is conducted using this machine with small amount of sample taken from the component surface.
The main body of the machine is the smallest and lightest, one tenth in size and one fifth in weight of the conventional equipment. Lever type loading system is employed. The specimen is set in the chamber with argon-gas atmosphere. Two pairs of displacement gages attached to the loading shaft increase measurement accuracy.
Comparison with a conventional specimen
Small punch creep testing
The time to rupture, creep curve, and creep rate are obtained from creep testing on a small punch creep testing machine.
