Ultrasonic Flaw Detector NOVOTEST UD-2301

Ultrasonic flaw detector UD2301 is designed for nondestructive testing of metals, plastics, glass, composite materials, weld inspection and measurement of the thickness of the various products and structures. The display of device can be operated in any orientation - there are 4 options of display rotation allow user to customize the unit by himself and lefties and righties,and the instrument display can be in both portrait and landscape orientation. Flaw detector is equipped with a standard type AA rechargeable batteries. The device can also operate from simple batteries same type. Using the batteries of standard type allows autonomous operation of the device in almost any conditions - if not the ability to charge the device, it is possible to have a supply of batteries, or buy them at any store. 

The LRM®XXI Diagnostic System provides high quality magnetic Non Destructive Testing of SteelWire Ropes, Conveyor Belts and Steel Tubes. The System is very helpful in evaluating the technical condition of tested object. The LMA Signal measures loss of metallic cross-sectional area (LMA) caused by corrosion, abrasion, etc. The LF Signal can indicate localized flaws (LF), for example broken wires, corrosion pitting, etc. Common Wire Rope application are: Inspection of Mine Hoist and Mine Elevator Ropes,Inspection of Crane Ropes ,Inspection of Guy Ropes on Flare Stacks,Inspection of Ski Lift Ropes and various Ropes for Amusement Rides 

 LRM Elevator wire rope tester-LRM MH - LIFT

Wire rope is a very important, but high-risk component of elevator equipment as it directly concerns the safety of passenger life and property. For a long time, due to the lack of reliable inspection equipment, wire rope safety has always been a “blind spot” of elevator safety management and even the “hidden danger” for passengers’ life. LRM-MH – LIFT For testing elevator wire ropes1 to 8 wire ropes in the set,diameter from 6mm to 18mm. Steel Cord Conveyor Belt Inspection System LRM MH - 400 For testing conveyor belts-Steel Cord Conveyor Belt Inspection System. 

Ultrasonic Testing

Ultrasonic testing is carried out using an ultrasonic flaw detector and an ultrasonic probe. In the inspection, ultrasound is sent into the area of interest. The ultrasound can be reflected from an interface (ex.Discontinuity) and received by the probe. The reflected ultrasound is displayed on a cathode ray tube screen in the flaw detector and the signal can be analyzed. This method of inspection is normally carried out on butt welds and is usually limited to section thickness of 8mm and above. It is technically difficult to perform the inspection on thin materials using conventional ultrasonic equipment. This method is good for detecting internal discontinuities. Surface or near surface discontinuities may not be easily detected. 

Magnetic Particle Testing

Magnetic Particle Testing is an inspection method with which defects on or close to the surface (to a depth of approx. 2 mm) in a ferro-magnetic material can be traced. It uses the principle that a crack or other discontinuity on the surface causes a magnetic stray field in a magnetized object. A crack will be made visible by an interruption of this field. The indications that are found are judged by their nature, size and location with the aid of an inspection standard. The shape or dimensions of the object do not or do not generally limit it. As with radiographic and ultrasonic inspection, the method can also be used well in the field or in companies. 

Dye Penetrat Testing

Dye Penetrant Testing is a technique by which a specially designed colored dye is used in conjunction with specially formulated developers are used to detect surface breaking indications on any ferromagnetic or non-ferromagnetic material to assist in determining the material integrity. Applications include determining weld surface integrity and detection of defects of all types of surface breaking discontinuities resulting from many different reasons. Dye Penetrant testing can be used on practically all materials. However, a condition is that the materials have a solid shape and are non-porous. As a rule this concerns non-magnetizable materials. 

On-Site Hardness Testing

Conventional hardness testers, like Rockwell, Brinell or Vickers machines, require the test piece be brought to the testing device; but this is not always possible. Portable testing devices have been developed that permit in-situ hardness measurements thus offering quick and economical supplements to conventional, stationary testing machines. We offer on-site hardness testing services using portable hardness testers.
