DataTime:[2016-8-12]
D 150 mm stainless steel pipe fittings or less, because the stainless steel pipe bending without heating, the stainless steel tube bending aluminum pipe and copper pipe, cold bending heat is more appropriate.
Stainless steel pipe fittings' cold bending processing, tube don't need to pack sand (except for larger diameter and wall thinner), usually conducted on manual or motorized pipe bender.
When the stainless steel pipe outside diameter greater than 60 mm must be placed in the tube bending mandrel bending. Outside the mandrel margin is smaller than stainless steel pipe diameter 1 ~ l. 5 mm, on stainless steel pipe fittings began to bend and slightly forward. Ball part of the heart library boundary with cylindrical part should always keep in the beginning of the stainless steel pipe fitting curved surface. If the mandrel stretched out before, is likely to make the mandrel fracturing; Without mandrel to position, and stainless steel pipe fittings causes excessive ovality.
A large number of bent pipe, use the motor tube bending machine.
Stainless steel pipe fittings is one of the books to parts of piping, it originated in the connection between tube and tube and the turning of pipe, branch, variable diameter, or closed, and then the pipe installation and maintenance (such as union).
