Routine Pipeline Inspection For Leakage-Free In Pipelines

Some of the biggest problems especially faced by the oil and petrochemical industries relate to the leakages in pipelines and the failure to stop these leakages from happening altogether or at least to detect these at an early stage. Pipeline inspection is therefore the only option to ensure checks and to stop prolonged leakages from happening. The best inspection services firstly have experienced technicians who are reliable, qualified as well as duly certified. Secondly, these services use the latest equipment with proper calibration and deliver on schedule in accordance with approved procedures.

Pipelines inspection services have full competence in advanced Non Destructive Testing (NDT) techniques, data management and materials engineering besides the supervision and management of projects. The NDT techniques include those by magnetic testing, radiographic techniques and ultrasonic testing besides visual methods. These services also offer the expertise of the company’s materials engineering facility that includes both testing and analysis in their in house laboratory. Therefore, there is no need for you as their customer to go to another company for your standard samples or for analysis after the testing has been completed.

Magnetic testing includes Alternating Current Field Measurement (ACFM) technique and Magnetic Flux Leakage (Induction) besides other techniques. Whereas ACFM employs electromagnetic principles for the detection of cracks and their sizing the Magnetic Flux technique is an NDT method to detect corrosion or pitting in pipelines in order to prevent leakages from happening altogether.

Pipelines inspection services employ ‘In-Line Inspection’ or ILI tools. These tools actually travel within the pipeline while they collect data. The Magnetic Flux Leakage inline inspection or MFL-ILI is the inline tool to detect areas affected by corrosion and assess these areas before initiating damage control.

Ultrasonic methods employed by pipelines inspection teams use corrosion mapping, advanced flaw sizing and Electromagnetic Acoustic Transmission or EMAT among others whereas radiographic methods use Gamma Radiography using cobalt, iridium or selenium. X-ray equipment is also used for the inspection of pipelines.

If your company has the requirement of prevention of leakages and prompt detection of the source of these leakages before reaching criticality you need the services of a professional pipelines inspection company.

Digital Radiography – a Must in Dentistry

Digital Radiography – a Must in Dentistry

Dr. Steve Thompson DDS

Paper x-rays and digital x-rays effectively provide diagnostic information. Though paper x-rays have been used traditionally, developments in recent times see dental professionals using the modern technology of 'digital radiography'.

'Digital Radiography' involves the use of a small sensor, which is briefly placed in the mouth during the x-ray process. This sensor is like a tiny camera which is more sensitive to x-ray light than normal light.

The immediate benefits of Digi Images over conventional X-Rays:

1. The captured image is displayed on the computer screen, saving time over the traditional paper x-rays.
2. Digi radiographs also do not need any chemicals for developing, rendering them environmental friendly as well.
3. Digi Radiographs also provide larger and far detailed images, comparatively. Modern computing software also permits extensive handling of the image – magnification, rotation, contrast adjustment and even color coding of the various element of the tooth for educational purposes.
4. Due to the quick result & easy manipulation of the image, the patient-doctor communication is enhanced.
5. Also these digital images make for easy and uncluttered filing – making accessing these digital records a breeze.
6. Obviously, they also are free from wear or tear.

Patients worry about the radiation exposure they may face with every x-ray. Dentists are no different in this worry, and follow the ALARA principle to ensure minimal radiation as well. ALARA is an acronym for 'As Low As Reasonably Achievable.'

Though digital radiography is a quick and easy method of diagnosis, the dentist does keep its use to the minimal to comply with ALARA & reduce the radiation exposure.

Over time with scientific developments, radiation exposure though xray has been reducing, let’s say 10 or 20 or even 30 years ago. This has been possible primarily because the amount of exposure per radiograph has decreased hugely over the last few decades.

Newer digital radiography is now available and it offers dentists excellent diagnostic results.  It has also decreased radiation exposure by up to eighty percent.

The digital images are stored in the patient's computer file and these can be easily printed or emailed for communication with the patients, specialists or even insurance companies. It is also easier to compare images from one appointment to the next to allow the dentist to notice changes that may occur over a period of time.

To summarize:

• Digital radiography improves diagnostic ability
• It is faster
• It decreases radiation exposure
• Improves communication between the dental professional and the patient
• Images can be easily stored and also easily accessible
• Software enables the images to be enhanced

In today's modern age, most dental offices have begun using digital radiography in order to take advantage of all the features available with the newer technology. Do ensure that your dentist uses digital radiography too.
