Stainless steel elbow use precautions

The corrosion resistance of stainless steel decreases with the increase of carbon content. Therefore, the carbon content of most stainless steels is low, the maximum is less than 1.2%, and the wC (carbon content) of some steels is even lower than 0.03% (such as 00Cr12). ). The main alloying element in stainless steel is Cr (chromium), and steel has corrosion resistance only when the Cr content reaches a certain value. Therefore, stainless steel generally has a Cr (chromium) content of at least 10.5%. The stainless steel also contains elements such as Ni, Ti, Mn, N, Nb, Mo, and Si.

Stainless steel elbows are used and maintained in an accurate and fair manner. The notes are as follows:

1. Ball valve of stainless steel elbow, stop valve, gate valve only when fully open or fully closed, do not allow to adjust the flow, so as to avoid erosion of the sealing surface and accelerate wear. The gate valve and the upper thread stop valve have a reverse sealing device, and the hand wheel is screwed to the uppermost position to prevent the medium from leaking from the packing.

Second, long-term storage of stainless steel elbows should be checked on schedule, often the exposed surface must be kept clean, remove dirt, neatly stored in a place where the room is airy and dry, no stacking or open storage. Always keep the stainless steel elbow dry and ventilated, keep the cleaner clean and tidy, and store it according to the exact storage method.

3. When installing, the stainless steel elbow can be directly installed on the pipeline according to the connection mode, and installed according to the position used. Under normal circumstances, it can be installed at any position of the pipeline, but it is easy to check the operation. Keep in mind that the flow direction of the stainless steel elbow should be upward from the longitudinal valve. The stainless steel elbow can only be installed horizontally. Stainless steel elbows should be carefully sealed during installation to prevent leakage and affect the normal operation of the pipeline.

Commonly used grades of precipitation hardening stainless steel are 04Cr13Ni8Mo2Al and the like. It can be treated to hard (strong) stainless steel by precipitation hardening (also known as age hardening).

LED Searchlight

‌‌A searchlight is a device with a powerful light source and a concave mirror, mainly used for remote illumination and search. ‌A searchlight concentrates the light in a very small solid Angle (generally less than 2 degrees) through a mirror or lens to obtain a large light intensity. Most of these devices are attached to tripods or mobile vehicles, and large searchlights even have dedicated vehicles, such as trucks. The history of searchlight can be traced back to the 19th century, with the development of technology, modern searchlight has high efficiency, intelligent control and other functions, widely used in ‌ military, ‌ navigation, ‌ search and rescue, ‌ construction and large sports venues and other fields. ‌
The core advantages of searchlights are their powerful light source and precise optical system, usually using high-intensity discharge lamps (‌HID) such as ‌ xenon lamps or ‌LED as light sources to achieve high brightness illumination over long distances. LED light sources are becoming the mainstream choice because of their energy saving, long life and low heating characteristics. The mechanical structure of the searchlight includes a robust stand and an adjustable rotating mechanism, ensuring stability and flexibility in a variety of environmental conditions. In addition, the modern searchlight is also equipped with an advanced ‌ control system, which supports manual and remote control operation to achieve precise control of the beam.
The searchlight is designed with durability in mind in extreme environments, using water -, dust -, corrosion - and earthquake-resistant materials and construction to ensure stable operation in harsh environments. The appearance design takes into account practicality and aesthetics to meet the aesthetic and functional requirements of different application scenarios. With the continuous progress of technology, the performance and intelligence level of searchlights will continue to improve to meet the changing market demand.
