Hydrostatic testing

Hydrostatic testing of pressure piping is a mandatory activity before finalization of any new or modified piping system. It is the final check of mechanical integrity of the whole system and should be followed religiously as after this activity the pi...

DR flat panel detector - indirect flat panel detection techn

Indirect flat panel detection technology uses a fluorescent substance (germanium iodide) to convert X-rays into visible light, which is converted into an image charge signal by a photoelectric acquisition circuit....

THE ABCS OF EDDY CURRENT

The advantages of eddy current inspection include its effectiveness in detecting surface-breaking flaws and ability to be used on wet surfaces...

DR flat panel detector---direct flat panel detection technol

The core component of the DR system is the flat panel detector, which is a detector that converts X-ray energy directly into electrical signals to produce X-ray images....

Hazards from overpressure from a ruptured vessel or piping s

The atmospheric boiling point of LNG is approximately -160°C, any residual water left in the equipment, such as by hydraulic pressure testing, is undesirable....

X ray inspection--Exposure conditions

X-ray photography, when the focal length is 700mm, the recommended value of the exposure is not less than 15A.min, when the focal length changes, the recommended value of the exposure can be converted according to the exposure factor formula....

Risks of Pneumatic pressure testing

Pneumatic testing is widely used to achieve minimum down time and economy and convenience of testing as compared to hydrostatic tests....

X-ray inspection technology---Geometry condition

When using the source in the center of the circumferential exposure, as long as the obtained film blackness and image quality meter meet the requirements, the f value can be reduced, but the reduction value should not exceed 50% of the specified value...

Industrial radiography

Industrial radiography is a method of inspecting materials for seeing hidden flaws by using the ability of short X-rays, gamma rays and neutrons to penetrate various materials....

X-ray inspection process

The blackness meter error is less than or equal to 0.05, the blackness meter is calibrated at least once every six months, and the blackness meter is sent at least once every two years....
