Processing requirements and general rules for copper pipe straight pipe
Jan 22, 2019

The basic requirements for the finished copper pipe straight pipe are: clean and smooth inside the pipe, no oxidation, no water, no oil. Do not use copper tubes with cracks, non-circular deformation, distortion, visible blisters, inkjet (marked by copper pipe factory), blackening (oxidation) and other defects.


The processing requirements of the straight pipe of copper pipe mainly include: the processing of the pipe must be carried out in accordance with the requirements of the design drawings. The shape and size of the product should meet the design requirements; the diameter change at the fracture should be within 2% of the standard diameter of the copper pipe, and the fracture No flashing or burr is allowed; the pipe parts should be deoiled, decontaminated, and free of copper scraps. The inner and outer surfaces are smooth and clean, and no oil, scratches or scales are allowed. The welding process must be protected by nitrogen, and the welding is dried with 0.3~0.5MPa. The air blows the inside.


During the straight pipe processing of the copper pipe, during the cutting process of the blanking and deburring stages, the copper pipe should be kept evenly fed to ensure the smoothness of the pipe. After the material is cut, the copper pipe trimmer must be used to deburr the port. After deburring, the copper and dust inside and outside the pipe must be blown off with 0.3~0.5MPa dry compressed
