special shaped copper pipe and shaped copper tube

special  shaped copper pipe and shaped  copper tube     From the aspect of the copper and aluminum tubing, in addition to any kind of pipe outside tube is shaped tubes. Type example: Folding Edit this paragraph RHS RHS points inward from the outer appearance, two kinds of foreign inner circle. Production size requirements to know: outside, inside edge (inner circle directly), external angle 4 R angles. Character tube Pipe character is named from the shape. Production size requirements to know: internal diameter small round, up and down inside the 8-word length, and wall thickness.
Hexagonal tube Hexagonal tube shape is also more named. Production size demanded to know: External two pairs of side edges, wall thickness, external 6 R angle perspective. Brush Tube Full name brush holder brass. Broadly divided into two categories: One is the intermediate projection plane. Production size needs to know the thickness, and internal dimensions (a = long side of the side length, b = shorter side of the side length, c = projection height between planes, d = length of the portion of the lower portion of the projection, e = raised portion The upper portion of the length). Another intermediate projection is circular. Production data size needs to know relatively less: wall thickness, and internal dimensions (a = long side of the side length, b = shorter side of the side length, c = raised circular diameter).
Other species Pipes are many species.
