What is the difference between primary processing and secondary processing of stainless steel shaped pipes?

டிhe groove pipes, door frame pipes, bamboo joint pipes, hexagonal pipes, patterned pipes, முதலியன. seen on the market are all stainless steel shaped pipes.

How are shaped pipes produced? Today, the editor will provide you with a detailed introduction.

The processing of stainless steel shaped pipes can be divided into three types: primary forming, secondary forming, and bending and welding of stainless steel plates.

One shot forming processing refers to the process of dividing the sheet metal into strips and directly extruding it into a composite mold on the welded pipe production line before welding it into the target shape.

• Advantages: The one-time molding process does not undergo secondary plasticity, and the shaped pipe is more sturdy and less prone to cracking.

• Disadvantages: Due to the limitations of processing technology and mold technology, it is difficult to produce pipes with complex shapes.

The common types of special-shaped pipes processed in one molding process include patterned pipes, bamboo joint pipes, hexagonal pipes, elliptical pipes, flat elliptical pipes, grooved pipes, and so on.

Secondary forming processing refers to the process of multiple machining processes on the basis of circular and square tubes to achieve irregular shapes.

• Advantages: Secondary molding processing can produce more special-shaped pipes of different shapes.

• Disadvantages: The qualification rate of the finished product in the secondary molding process is low, and the stability after multiple extrusion deformations is not as strong as that of the primary molding product.

The third type of shaped pipe is formed by bending and welding stainless steel plates,

The use of sheet metal bending special shaped pipes is relatively rare, and the bending pipes do not have an R angle. The shape is complex and there are many bends, and the connection position is connected by welding.
