1.Perform bending of the pipe using the bender which has
Spring
a specified bending radius.
2.Be sure to take full care to perform bending of the pipe
successfully at one time.
Bending and unbending the pipe more than twice makes
the bending work increasingly difficult.
3.You may use the spring inserted into the gas pipe instead
of the bender to bend the pipe.
4.When you bend the pipe using the spring, hold the pipe with both
hands to prevent any distortion, and secure a minimum bending
radius of more than 100mm (4inch)
