Second, it is prohibited to accidentally modify the explosion-proof camera structure, components and equipment of the internal circuit. The fastening bolts shall not be interchanged or missing, and the elastic gaskets and metal gaskets of the extra inlet and outlet ports must be kept sealed at the factory, and the compression nut should be tightened to seal the inlet.
3. It is forbidden to carry live electrical equipment and lines in explosion hazardous locations, and to prohibit transmission of electricity or power outages. And a warning sign “Someone working, no closing†should be hung on the offsite. During inspection and maintenance, if the explosion-proof camera is disassembled into a safe area, the equipment power cable end of the site shall be properly handled and shall not be powered on.
Fourth, daily operation and maintenance inspections, should try to avoid opening the explosion-proof camera housing, must first open the power should be cut off. If the explosion-proof enclosure is opened, the explosion-proof surface shall be properly protected and shall not be damaged. During the inspection, the explosion-proof surface shall be placed upwards, and shall not directly touch the ground. After the scene is cleaned, it shall be coated with a phosphatizing paste or 204 anti-rust oil.
5. All explosion-proof cameras should establish equipment files, install, test, operate, and repair equipment, and decompress and decompose the equipment until it is decommissioned. Various technical data of different periods should be collected, archived, and numbered one by one on the equipment.
Couplings are used to connect two joints of TUBING coupling or CASING pipe together.
Couplings are short length of heavy wall pipe with the same threads on each end.
EASTSUN manufactures tubing coupling and casing tubing coupling strictly comply with API 5CT latest standard.
The steel coupling is mainly used to connect oil pipes in pil drilling.
This product can be used to connect the shafts of units that are
manufactured separately.
It can fit the misalignment of the shafts or introduce mechanical flexibility.
The pipe coupling is capable of reducing the transmission of shock losds from one shaft to another.
It can also introduce protecyion against overloads.
The steel coupling can be used to alter vibration characteristics of
rotating units.
Pipe coupling is also used to connect drilling par and driven part.
