The way the mining pipe card is made
In terms of how to make mining pipe cards, we will analyze the relevant situation that our company knows or understand, so that you can have more knowledge about the industry in addition to understanding our company!
1. Ordinary pressure piping system for underground coal mines
2. Common pressure piping system for mining and mining
3. High-rise building fire pipeline system Size range: 33-630mm
4. Flexible connection, strong adaptability, can provide 0 degree to 4 degree deflection angle
5. The mining pipe clamp has the functions of damping vibration and absorbing thermal expansion and contraction
6. The surface of the joint is painted with orange-yellow paint for mining pipe fittings. What are the functions of mining pipe fittings? Hot-dip galvanized or plastic-coated
Mine pipe card production method:
1. Mine pipe clamps by forging method: use a swaging machine to punch and stretch the end or part of the pipe to reduce the outer diameter. Commonly used swaging machines include rotary, connecting rod and roller types.
2. Bending forming method for mining pipe clamps: There are three methods commonly used, one method is called stretching method, the other method is called punching method
3. Roller method mining pipe clamp: place the core in the pipe, and push the outer periphery with rollers for round edge processing.
4. Mine pipe clamps by rolling method: generally no mandrel is required, and it is suitable for the inner round edge of thick-walled pipes.
5. Stamping method for mining pipe clamps: use a tapered core on the punching machine to expand the pipe end to the required size and shape.
