According to Directive 1999/92/EC, steel tools are considered to be a source of ignition and therefore unsafe for use in the presence of explosive atmospheres. In such environments, non-sparking tools must be used. However, based on our experience in the industry worldwide, there are still many purchasing, maintenance, and even safety professionals who are not fully familiar with what non-sparking tools are and what the key criteria are for use when purchasing or using such tools. The most common non-sparking alloys are aluminum - bronze (Al-Bron) and copper - beryllium (Cu-Be), but what criteria should be followed when choosing one of these options? Explosion-proof Durable Hand Tools Aluminum Bronze Edging Spade Type of gas in the environment Despite its name, non-sparking tools do produce sparks (all metals produce sparks when they rub against each other). The difference between non-sparking too...

Anti-corrosion coated steel pipe, through the anti-corrosion process, is to prevent corrosion or slow down corrosion in the chemical or electrochemical reaction that occurs during the transportation and use of steel pipes. According to our statistics, China's annual economic losses due to pipeline corrosion exceed 280 billion, and global annual pipeline corrosion losses amount to 500 billion. Anti-corrosion coated pipelines can effectively stop and slow down erosion, so the technology is widely used in industry. Anti-corrosion steel pipes are mainly used in petroleum, chemical, gas, heat, sewage treatment, water, bridges, steel pipes and other engineering fields in China. Anti-corrosion steel pipes are divided into the following categories. IPN8710 corrosion When steel corrosion in more kinds of media, such as acids, alkalis, salts, oxidizers and water vapor, the coati...

80% of the total sales of graphite electrodes are used as conductive materials in electric arc furnace steelmaking. Next, the Dan carbon graphite electrodes will introduce what the graphite electrodes are used for? Uses and properties of graphite electrodes. 1. What is the graphite electrode used for? Graphite electrode is a conductive electrode used in the electric furnace in the process of steelmaking in a medium-sized electric arc furnace. After passing electricity between the electrode and the charge or between the electrode and the electrode, an arc is generated to heat and smelt the scrap steel, similar to the lightning effect. The main raw materials for the production of graphite electrodes are petroleum coke and needle coke. Coal tar pitch is made as a binder through calcination, kneading, pressing, roasting, impregnation, graphitization and machining. The graphite electrode is divided into a body and a joint, and the joint production process requires three immersion and four b...

  Many walkers swear by them, while others swear they are annoying. Walking sticks seem to divide the walking community, but today more and more people are picking up their canes and enjoying the benefits. Studies show that there are many recommendations for using   trekking (or hiking) poles   or crutches if you plan to go on a walking vacation, especially if your daily walks are long or hilly, or both. Why use  trekking poles ? Using crampons has been shown to reduce the cumulative stress on your feet, legs, knees and back by sharing the load more evenly throughout your body. This is especially true when carrying a heavy backpack. Hiking poles can also. Protect your knees, especially when walking on steep hills. Improve your strength and endurance when walking uphill. Help maintain balance on uneven trails. Improve posture, making walkers more upright while walking, which in turn helps with breathing. Increases speed, especially on downhills. Provides additional st...

  When it comes to outdoor decorative lighting, nothing is more popular than  outdoor waterproof string light . If you have an outdoor lighting display, you may have realized the worst enemy of string lights: rodents. Main culprit? Squirrel. Some people may think that these animals are just furry little cuties, but many people think that they are the real wire-chomping scourge. Why do rodents declare war on lighting? What can you do to deal with this threat? Why does the squirrel bite the wire? Squirrel's food is mainly hard seeds, nuts, and fruits that wear out teeth. To combat this situation, their teeth are constantly growing. Therefore, they must chew things to prevent their teeth from growing too long. Most squirrels chew on things like branches and twigs. However, the urban squirrel found the electrical wire wires also work just as well and usually have a delicious soy-based plastic cover. How can we stop them? Fortunately, there are many options to help protect your str...

 A  booster compressor  is a type of compressor made to boost pressure in a system, typically by four to six times the normal pressure produced by machines in factories. Most factories that need a booster compressor only use this temporarily, because sustaining such high pressure can be difficult and costly. While this can be used to work a device, it more often is used for tests. Most of these compressors are pneumatic, or use air, but some have other power sources. Factories are where most booster compressor devices are found, because few consumers need the high pressure and power these compressors can offer. Factories' machines commonly are equipped to output about 100 pounds of pressure per square inch (PSI) (6.89 bars), which is enough to run most devices, but not enough for some other uses. When a higher PSI is required, these boosters are used, and they commonly can output from 400 to 600 PSI (27.57 to 41.36 bars). Most factories are capable of boosting their own P...
