On the Application of LED Explosion Proof Lamps in Hazardous Environment
According to the State Administration of Work Safety issued by the State Administration of Work Safety on October 22, 2007, all electrical components in hazardous locations specified in the “Safety Code for Electrical Explosion in Hazardous Locationsâ€, which was implemented on January 1, 2008, must use the explosion-proof rating specified in the site. Explosion-proof electrical. Where are we today's topic "on the LED explosion-proof lights for places" can be satisfied with the specification to get a satisfactory answer. 8.12 Tianjin chemical warehouse accident, 8.2 Kunshan metal products manufacturer accident, 4.15 Dalian East China Gas Plant accident, 6.5 Linyi Jinyu petrochemical accident, etc.... How many painful lessons! Where are the lessons of blood! We should keep in mind that we must always keep in mind safety production and cherish life!
First of all, we talk about the term "dangerous environment" mentioned in the code. In dangerous environments, we can choose composite explosion-proof LED explosion-proof lamps based on hazardous gases, dust, weeping materials, steam, fiber, chemical residues, chemical gases, oil-gas products, liquefied gas, and so on. In this way, starting from the source of our production environment, each of us should always pay attention to whether our work environment is safe and reliable! Let each of us do environmental safety auditors.
How to determine the application of LED explosion-proof lights, and the distinction between explosion-proof grade?
1. Explosion-proof LED explosion-proof luminaires shall be selected in different environments and different explosion-proof measures shall be used to ensure the safety of the environment. First of all, distinguish the size and level of the dangerous environment.
2. Based on the degree and duration of the mixture in the hazardous gas, the hazardous area is affected by the size of the ventilation condition, the characteristics of the release source and the performance parameters of the dangerous goods.
Dangerous places are divided into three areas: Zone 0, Zone 1, Zone 2, Zone 10, and Zone 11.
Zone 1 and Zone 0 refer to areas where explosive gas, vapor, or mists appear continuously or for a long period of time or in a short period of time during normal operation. In addition to the enclosed space with hazardous substances, there is very little area 0.
Zones 2 and 1 are areas where periodic, or accidental, baoza gas, vapour or mist are expected during normal operation.
Zones 3 and 2 do not appear during normal operation, and even if they appear, they are areas where baoza gas, vapor, or mist accidentally occur.
Zones 4 and 10 refer to areas where baoza dust and fibers frequently appear during continuous operation or for a long period of time or for a short time.
Zones 5 and 11 are areas that do not appear during normal operation. They only occasionally appear explosive dust and fiber when they do not operate normally.
Finally, let's talk about what should be the LED explosion-proof lighting fixtures that are suitable for use in hazardous environments. Firstly, the appropriate LED explosion-proof lighting fixtures can be selected through different hazardous environments, irradiation areas for applicable sites, different installation methods for applicable locations, explosion-proof grades and protection levels applicable under hazardous environments.
Diameter Tape Measure
Basically there are two types of Diameter Tape Measure, one is Pipe OD Tape Measure Diameter Circumference, another is ID (Inner Diameter) PP Tape Measure
Pipe OD Tape Measure Diameter Circumference
Product Description:
The 2-meter Pipe OD Tape Measure Diameter Circumference is made of reliable material to satisfy precise diameter measuring requirement.The reading for the perimeter, accurate to 1 mm. The tape is double sided with circumference (measures in cm & inch) and diameter (measures in inch & inch) on the either part. Pipe od tape measure adopts fiberglass tape to deliver water and stain proof effect and to ensure that it is of good elasticity for diameter measuring. The retracting mechanism is built in the durable ABS case, thus service life is extended. Wintape provides the diameter tape measure with other patterns and offers customized logo for you.
ID (Inner Diameter) PP Tape Measure
Product Description:
Inner diameter tape measure is made of PP material that is of excellent stress tensile strength and high elasticity. The scale numbers are already been calculated so the tape gives you the result directly without calculating. The practical ID measuring tape can be adopted in various ways such as pipe and container measuring. The double sided inner diameter measuring tape makes number reading easier and more convenient.
