Copper nickel elbows wall thickness larger than 2.5mm need to be beveled. Copper nickel elbow wall thickness less than or equal 2.5mm not require beveling.
The thickness of both the end and bend of the copper-nickel elbow meets DIN86090 and EEMUA234 standard. You need 89*2.5 elbow, we undercut the pipe is 89*3.
Undercut pipe wall thickness is thickened by 0.5mm, because the elbow wall thickness will be thinned when bending.
The process of our copper nickel elbow bending is internal steel ball push. Outside plus the mold, multiple push bending molding. This process has a low amount of thinning, and does not cause damage to the mechanical properties of the pipe.
The copper nickel elbow can also be made into 15 degree, 30 degree, 60 degree.
The first thing is how many degrees of elbow, followed a short elbow or a long elbow.
