Anonymous users2024-02-06The specifications for the installation of natural gas pipelines are as follows:
1. The connection between the gas pipeline and accessories can be flanged, threaded, and welded in other parts as much as possible.
2. The vertical weld of the gas pipeline should not be less than 300mm from the edge end of the support, and the horizontal weld should be located above the support.
3. Measures should be taken to eliminate static electricity and lightning protection for gas pipelines.
4. Coal pipelines with high carbon monoxide content such as blast furnace gas and converter gas should not be buried.
5. When the overhead gas pipeline is laid together with other pipelines, when the gas pipeline is laid on the same pillar or trestle with the sewer pipeline, fuel pipe and non-combustible gas, the vertical clear distance between the upper and lower laying should not be less than 250mm. The operating devices of other pipelines co-erected with gas pipelines should avoid gas leakage parts such as gas pipeline flanges, gate valves, and flaps. Power cables and wires should not be laid on gas pipes and supports, except for cables used in gas pipelines.

The ultrasonic welding device converts the current 50 60hz electrical frequency into 20kHz or 40kHz high-frequency electrical energy through a transistor functional device, and gives it to the converter. The converter converts the electrical energy into the mechanical vibration energy used for ultrasonic waves, and the voltage regulating device is responsible for transmitting the converted mechanical energy to the sonotrode of the ultrasonic welding machine. The sonotrode is an acoustic device that transmits mechanical vibration energy directly to the product to be pressed. >>>More
All welds should be qualified according to ISO-15614, but butt welds such as 6+6, 8+8 and steel pipe welds are qualified. Crane Specification 6067
Laser welding is a new type of metal welding technology, long-term engagement in this kind of work will make people's eyes and face suffer a certain degree of harm, therefore, practitioners should wear masks, as far as possible to minimize the harm, at the same time, you can usually eat more black fungus or mushrooms and other mushroom food, which will be good for the body.
Hello, we need to bring a welding mask, if you are soldering for a long time, it is recommended that you go to the pharmacy to buy some eye drops, and when there is nothing to do, order a little!
Electric welding, gas welding, argon arc welding, CO2 can be used.
