Puretube UBC Ba welding drawing straight pipe (seamless welded pipe) is defined as welding + oil drawing + oleic acid washing + ultrasonic cleaning + dust-free clean packaging. Cold drawing extrudes the weld through internal mold external mold, which overcomes the weaknesses of weld in terminal application, such as cleanliness requirements, leakage risk, difficulty in bending. Through the strict process requirements, we have achieved the super sanitary pipe with good cleaning property, which meets the requirements of RA < 0.6.Some customers will be hesitant when choosing welded pipe seamless pipe. We provide a better solution for this problem. The tube can be widely used in applications with cleaning requirements, such as biopharmaceutical industry, automobile manufacturing industry, fine chemical industry, food beverage industry. On the premise of meeting the requirements, the use cost can be effectively reduced.
