Principle and practical application of laser surface cleaning (3)
Laser cleaning technology is widely used in weapon maintenance. The laser cleaning system can remove rust and contaminants efficiently and quickly, and can select the cleaning parts to realize the automation of cleaning. Laser cleaning is not only more clean than chemical cleaning, but also has no damage to the surface of the object. By setting different parameters, Quantel's LASERLAST can also form a dense oxide protective film or metal molten layer on the surface of metal objects to improve surface strength and corrosion resistance. The laser-cleared waste does not substantially pollute the environment, and can also be operated remotely, effectively reducing the health damage to the operator. 5.3 Removal of old paint from aircraft: Laser cleaning systems in Europe have long been used in the aerospace industry. The surface of the aircraft must be repainted after a certain period of time, but the original old paint must be completely removed before painting. The traditional mechanical paint removal method is easy to cause damage to the metal surface of the aircraft, posing a hidden danger to safe flight. If multiple laser cleaning systems are used, the paint on the surface of an A320 Airbus can be completely removed within two days without damaging the metal surface. 5.4 Cleaning of the exterior wall of the building: With the rapid development of China's economy, more and more skyscrapers have been built, and the cleaning problem of the exterior walls of the building has become increasingly prominent. The LASERLASTE laser cleaning system provides a good cleaning of the exterior walls of buildings through fiber optics up to 70 meters long. The solution can effectively clean all kinds of pollutants on various stone, metal and glass, and it is many times more efficient than conventional cleaning. It can also remove black spots and stains on various stone materials in buildings. The washing test of LASERLASTE laser cleaning system on buildings and stone monuments in Shaolin Temple of Lushan Mountain shows that the use of laser cleaning is very effective in protecting the appearance of ancient buildings. 5.5 Cleaning in the electronics industry The electronics industry uses lasers to remove oxides: the electronics industry requires high-precision decontamination, and is particularly suitable for laser deoxidation. Before the board is soldered, the component pins must be completely de-oxidized to ensure optimal electrical contact, and the pins must not be damaged during the decontamination process. Laser cleaning meets the requirements of use and is highly efficient, requiring only one laser to be applied to one pin. 5.6 Precision deesterification cleaning in the precision machinery industry: The precision machinery industry often needs to remove the esters and mineral oils used to lubricate and resist corrosion on the parts, usually by chemical methods, while chemical cleaning often has residues. Laser deesterification removes esters and mineral oil completely without damaging the surface of the part. The removal of contaminants is done by shock waves, and the thin gas layer of the surface of the part is explosively vaporized to form a shock wave, which leads to the removal of dirt rather than mechanical interaction. The material is completely de-esterified for the cleaning of mechanical parts in the aerospace industry. Oil ester removal in mechanical part processing can also be done by laser cleaning. 5.7 Pipeline cleaning in nuclear power plant reactors: The laser cleaning system is also used for cleaning pipelines in nuclear power plant reactors. It uses optical fiber to introduce high-power laser beam into the reactor to directly remove radioactive dust, and the cleaned material is easy to clean. And because it is operated remotely, it can ensure the safety of the staff. In summary, laser cleaning plays an important role in many fields, and in automotive manufacturing, semiconductor wafer cleaning, precision parts processing, military equipment cleaning, building exterior cleaning, heritage protection, circuit board cleaning, precision parts. Processing, manufacturing of liquid crystal displays, and removal of chewing gum can play an important role. Previous page
Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications.
Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe.

5.2 Cleaning of weapon equipment:
This type of joint connection is Speedy and simple but not suitable for high presser and temperature applications. Threaded Flanges are mostly used in utility services such as air and water.
Threaded (Screwed) flange is similar to the Slip-On flange, but the bore is threaded. Its chief merit is that it can be assembled withour welding, explaining its use in low pressure services at ordinary atmospheric temperatures, and in highly explosive areas where welding create a hazard.
The various types of threaded flanges are as follows:
Plain Threaded Flanges
Female Threaded Flanges
Male Threaded Flanges
