Cold press forming by mold is suitable for production of seamless carbon steel pipe fittings. Through this process where cold forming press and corresponding mold, we are able to make use of steel pipe of various sizes to produce elbow pipe fittings of corresponding size. For example, steel pipes with diameter of 4 inches are used for production of elbow with diameter of 4 inches.
Raw materials applied during this kind of production process are usually seamless steel pipes or welded pipes. The material could be stainless steel, duplex stainless steel, super duplex stainless steel, copper and aluminum. Since no further welding is required, the production process is much simpler than compression forming process for steel plate made pipe fittings production. The pieces outputted from the cold forming press will go into heat treatment directly. Then subsequent metal processing, surface treatment and pickling and passivation follows.Production Process
We have three sets of elbow cold press forming machines, which feature high automation degree, thereby being able to produce seamless pipe fittings with caliber ranging from 0.5 inches and 20 inches in quantity.
