How to properly bend galvanized pipe

The method of bending galvanized pipe depends on the desired bend angle, radius, and the need to maintain the integrity of the galvanized coating.

First, manual bending galvanized pipe steps
1. Preparation: according to the need to cut the galvanized pipe into the required length, the galvanized pipe is stuffed with the appropriate length of pure copper (can also be filled with sand, etc.) to avoid wrinkles or creases when the pipe is bent.
2. Selection of bending cam: according to the required bending radius to select the appropriate specifications of the bending cam, and will be fixed on the pipe bender.
3. Measure the length of galvanized pipe: mark a straight line at each end of the galvanized pipe, and use these two straight lines as a reference to measure the length of the galvanized pipe.

4. Processing bending: place the galvanized pipe on the bender by hand, gradually press down with the operating lever, and then turn the bender wheel to start bending the galvanized pipe.

Second, mechanical bending galvanized pipe steps
1. Preparation: cut the galvanized pipe into the required length, and clean the pipe of impurities, the galvanized pipe will be placed in the machine's feed port.
2. Adjustment of machine parameters: in accordance with the required bending radius, bending angle and bending radius and pipe diameter ratio and other parameters, adjust the working mode of the machine.

3. Start bending: After adjusting the parameters of the machine, feed the galvanized pipe into the bending mechanism of the machine and start the machine to start bending.

Third, the precautions
1. Before the bending process to carefully check the galvanized pipe for damage or cracks, otherwise it may lead to breakage.
2. In the bending process, be careful to observe the pipe wall for wrinkles and creases, if necessary, replace the pure copper strip and other fillers to avoid unnecessary defects when the pipe is bent.
3. According to the bending radius, bending angle and the ratio of bending radius and pipe diameter to choose the appropriate cam, otherwise it is easy to cause damage to the galvanized pipe and can not be bent.
4. In the bending of the pipe should try to avoid direct force pulling the pipe, so as not to trigger the galvanized layer breakage, you can use appropriate lubricants to reduce friction.

5. Bending angle is too large or too small can easily lead to pipe distortion or rupture, bending need to pay attention to the control of the angle.

Conclusion
We hope that the introduction of this article can help you to correctly carry out the bending process of galvanized pipe. The use of manual and mechanical methods need to pay attention to the control of the strength and operation of the norms, to avoid unnecessary losses due to incorrect operation. If you encounter problems in the operation process, please note that timely find the cause and solve the problem in time, in order to better complete the bending task.
