Copper tube, also known as copper tube, non-ferrous metal pipe, is a suppressed and drawn seamless pipe. Copper Pipe has a strong, corrosion-resistant characteristics, and become a modern contractor in all residential commercial housing in the water pipeline, heating, refrigeration piping installed first choice. Copper tube by use can be classified as general copper tube, oxygen copper tube, galvanized copper tube, metric copper tube, wire casing, roller tube, deep well tube, automotive pipe, transformer tube, welded thin-walled tube, welding special-shaped pipe and spiral copper tube.
(1) General Copper tube: general copper tube used to transport low-pressure fluid. Made of q195a, q215a and q235a steel. It can also be made of other soft steel which is easy to weld. Copper tube to carry out water pressure, bending, flattening and other experiments, on the surface quality has certain requirements, usually the delivery length of 4-10m, often require a fixed ruler (or double feet) delivery. The specification of copper pipe is nominal caliber (mm or inches) nominal caliber differs from the actual, copper tube according to the stipulation wall thick has ordinary copper tube and thickened copper tube two kinds, the copper tube is divided by the tube end form and the thread and without the thread two kinds.
(2) oxygen-blowing copper tube: used as steel-making oxygen pipe, the general use of small-caliber welding copper pipe, specifications by 3/8 inch-2 inch eight kinds. Made of 08, 10, 15, 20 or q195-q235 steel strips. In order to prevent corrosion, some aluminizing treatment.
