Application of Industrial Endoscope in Cleanliness Detection of Clean Pipeline in Pharmaceutical Industry

July 10,2019.

The pharmaceutical industry has very high requirements for the cleanliness of clean pipes.During installation, the internal environment of the pipeline must be smooth, and high-pressure cleaning, disinfection and drying should be carried out, and the number of microorganisms should be controlled to avoid contamination of the medicinal liquid.

The smoothness and uniformity of weld directly affect the contamination degree of liquid. To ensure that there is no suitable environment for bacterial growth in the interior, reasonable welding methods and sequence should be adopted in the welding of clean pipes to ensure that the appearance of weld on the welding surface is uniform and beautiful, the welding quality is good, and no welding defects can be put into use.

Clean pipeline installation requirements are very strict, so the quality of the weld is very high. The quality of the weld directly affects the level of liquid pollution. Professional tools must be used for inspection. For all completed automatic welding, at least the automatic welding and all manual welding need to be endoscopically inspected.

Smooth transition of standard welding seam and base material, no obvious internal concave or external convex on the inner surface, uniform welding wave, flat and straight, no welding deviation, no sand hole, no crack, no overheat or overburning of welding seam, etc.The internal and external surface of the welding seam is basically the same as that of the parent material, showing a silver-white color. The heat-affected zone does not change color, and there is no crack, interlayer and other defects.All welds shall be free from corrosion spots, pinholes, corrosion marks and spot weld marks, etc., and the internal and external surfaces shall be free from obvious concave and convex, and the welding wave shall be uniform and straight.After welding, the welding seam shall be inspected according to the endoscopic inspection procedures. The inspection standard shall meet the requirements of the design specification, and the unqualified welding seam shall be repaired according to the repair specification.

In addition to the pharmaceutical industry, there is also the food industry, such as beverage, dairy products and other liquid transportation, pipeline cleanliness is also particularly important.It is necessary to strictly control the internal colonies, foreign bodies and impurities to ensure food hygiene and avoid contamination.

Industrial endoscope is a portable tool used to detect welding inner surface defects and to take photos and videos. It can inspect the oxide skin, slag, bulge and depression on the inner surface of clean pipeline, and the foreign matter, impurities, paint, rust, profit and dirt affecting the cleanliness of pipeline, so as to clean them up and ensure the dryness of the inner wall. Clean and dry, to improve cleanliness is of great significance.

Coantec has reached in-depth cooperation with many well-known dairy and tea beverage enterprises in China. The self-developed industry peepscope has been widely used in the cleanliness detection of clean pipelines. With the stricter quality control in the food and pharmaceutical industry in China, more and more attention has been paid to the cleanliness of pipelines. It is believed that endoscopes will be more widely used.
