When using the UV aging test chamber, the lamp should pay attention to the common sense:
1. It is forbidden to touch the lamp by hand to avoid scratching or damage or to reduce the life of the lamp.
2. The lamp with the wiring direction requirement must pay attention to the direction. Failure to do so may result in damage to the lamp, reduced life or overheating of the lamp surface.
3, due to the pressure inside the lamp is very large, please avoid bumping, scratching and other external forces to damage the lamp.
4. Do not use it in places with flammable or explosive materials such as thinner materials. Failure to do so may result in fire or explosion.
5, UV aging test box lighting tube should not be directly with the naked eye to see, otherwise it will cause eye irritation or decreased vision.
6. Do not let the ultraviolet light directly shine on the skin, otherwise the skin will be damaged by ultraviolet radiation.
7. Do not touch the lamp that is lighting or the lamp that has just been turned off. Otherwise, it will cause burns due to excessive temperature on the surface of the lamp.
8. Do not bring flammable or explosive materials such as paper or cloth close to the lamp in use, otherwise it will cause fire due to excessive temperature on the surface of the lamp.
9. Please exhaust the air when opening the lamp in the sealed space. The ozone emitted by the lamp will cause great damage to the human respiratory system.
10. Restart or open the lamp cover after at least 10 minutes after turning off the lamp. Otherwise, the lamp may be damaged or burnt.
11. Install or replace the lamp. When cleaning the lamp cover, the power must be turned off. Otherwise, it may easily cause electric shock.

Stainless steel Flanges are essential accessories for pipeline connections. According to the standards, they are divided into JIS BS DIN ANSI GOST Italian standards. Among them, DIN, JIS, BS standard non-Carbon Steel Flanges are the most common, popular and widely used. flange. Stainless steel flanges are divided into two processes: forging and casting. Among them, cast stainless steel flanges have low price and stable performance, and are widely used in Europe and South Korea
The biggest features of stainless steel flanges are good stability, strong corrosion resistance, acid and alkali resistance, and are widely used in pipeline systems in chemical, pharmaceutical, food, pharmaceutical and other special industries.
When in use, the flange is evenly welded to one end of the pipeline with a special electrode, and then fastened with bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the entire pipeline is integrated and starts to work normally.
It is an indispensable pipe fitting that must be used in pipeline systems and equipment such as machinery, petroleum, chemical industry, water conservancy, medicine, food, and papermaking. It provides convenience for the cleaning, inspection and maintenance of the pipeline and reduces the engineering cost.
Types of stainless steel flanges:
According to the shape can be divided into: FF, RF, BLIND, SLIP-ON, Welding Neck
, Threaded , Socket Weld
According to the pressure can be divided into: PN10, PN16, PN25, PN40, PN63, PN100,
15OLBS.300LBS
According to the process, it can be divided into: forging flange, precision casting flange, steel plate flange
According to the material can be divided into: SUS304 SUS304L SUS316 SUS316L 321 201
According to the production process, it can be divided into: a: forged flange b: stainless steel plate flange c: precision casting stainless steel flange
