Business Overview -Services-


From the manufacturing of devices in the plant to post-delivery maintenance,
engineering such as design, analysis, inspection, and measurement is indispensable.

– What materials are pre-existing pipelines made from?
– How much has the current thickness been worn or deteriorated?
– Are there any abnormalities in pipe temperature, or the amount of vibration or displacement?
– What is the pipe device’s residual fatigue life?

At Neuron Japan, we visit each plant site and carry out situation assessment and diagnosis of plants using the most cutting-edge portable inspection and measurement devices. We also undertake testing for the residual life of existing expansion joints couplings.

Structural Design 2D, 3D [AutoCAD/SolidWorks]

3D Analysis (CCR)   3D CAD(Pressure Balance bellows-type)

Stress Analysis [Finite Element Method For Pipes]

Finite Element Method [ANSYS]   Piping stress analysis

Metal Analysis [Component/Structure]

Ferrite Scope (ferrite content measuring instrument)

(Made in Germany by F Company)
  The metallic ferrite *1even in Stainless Steel induces and promotes corrosion.
Ferrite scopes are able to non-destructively measure the amount of delta ferrite in the welding used in oil pipelines and pressure vessels etc., as well as in steel cladding.

Test Range 0.1~80%
Usage Temperature Range 5 to 45°C
Measurement Methods Electromagnetic Induction Method
Accuracy ±2%
Measurement Conditions Minimum Area (surface) φ area of 2mm of more
Minimum curved surface φ2mm or more
Dimensions/Mass W97 X H177 X D43mm 520g

*1. Ferrite
The phase (structure) of iron within the temperature range of 911°C or below in 100% pure iron. Within this range, iron takes on a body-centered cubic crystal structure. Also known as α Fe or α iron (alpha iron). The name is derived from the Latin for iron, “Ferrum.”

Portable Multi-use Hardness Testing Device

 (Made in SWITZERLAND by F Company)
  A revolutionary tester which operates on a principle (*1 EQUO principle) which is completely different from past penetrometers. It is a consistently important inspection device in the metalworking industry, and is able to non-destructively measure a wide range of products, including non-metallic soft materials.

Model Ecochip 2
Test Precision The average measurement margin for error is ±0.5%, or ±4 L-value units
Test Range
HL (L-value via Ecochip): 100~990
HRC (Rockwell): 20~70
HV (Vickers): 80~1211
HRB (Rockwell): 38~100
HB (Brinell): 19~686
HRA (Rockwell): 61~88
HS (Shore): 29~102
Dimensions/Mass L175 X W180 X H80 750g
*1 EQUO principle
Powered by a special spring, an impact body equipped with a test chip strikes and rebounds from the surface of the test piece. At that time, the impact device’s coils and the magnet installed inside the impact body activate and voltage is induced. This voltage, directly proportional to speed, is transmitted to the electronic mechanism, and is automatically digitally displayed as hardness value “L.”

Portable Metal Component Analysis Meter (for alloys)

(Made in the USA by R Company)
  A device which uses the principle of fluorescent X-ray spectroscopy (energy dispersal type) to detect the existence/content of specified elements in targeted metallic materials.
Unlike typical fluorescent X-ray spectroscopy devices, there is no concept of a sample chamber, allowing the device to be transported in order to take measurements. Can be used in recycling sample division/screening, and product intake testing/finished goods inspection/shipping inspection.

Model NITON XLt898
Range of Measurement-Targeted Elements Ti(22)~Bi(83) Gas, excluding volatile/ferromagnetic materials
Testing Area Measurement Window (10mm X 20mm, Kapton film)
X-ray Emitting Part Miniature X-ray straight ball Ag target (semitransparent type), and high-voltage emitting part 35kv
Calibration Function Automatic adjustment function equipped in main body (by operator designation)
Usage temperature range -7℃ to 50℃
Dimensions/Mass 248 X 273 X 95mm approx. 1.7kg

Helium Leak Detector

  The Helium Leak Detector is a fully-automatic portable model which delivers high sensitivity/low background, and which comes equipped with a molecular drag pump with a high compression ratio, and a high-performance analysis tube. In leak testing, this method is able to detect the finest leaks.

Model MSE-2000
Test Port Max. Pressure 2000Pa (1000Pa during rough switchover)
Detection Sensitivity 1 X 10-12~1 X 100 Pa m3/s [He]
Exhaust-related Molecular drag pump, specialized-oil rotary vacuum pump
Analysis Tube Thoria-coated iridium filament (two equipped)
Usage Temperature Range -7℃ to 50℃
Dimensions/Mass W280 X H630 X D530mm approx. 45kg (main body)
In helium leak testing, it is able to detect even extremely fine leaks of (5 X 10 – 13Pa/m3/s), so small that at a rate of 1Pb, 1cm3 of air would take approximately 6,000 years to fully leak. In leak testing, this method is able to detect the finest leaks.
