Process characteristics of hot expansion tube

Hot expansion tube process is a technology that simultaneously expands the diameter and wall thickness of the tube by heating and mechanical expansion. Its main features are as follows:

1.High material utilization rate:

The hot expansion tube process can make full use of raw materials and enlarge the size of the original tube through the expansion process, thereby reducing material waste.

2.Wide range of applications:

It is suitable for tubes of various metal materials, such as carbon steel, stainless steel, alloy steel, etc., and can produce tubes of different specifications and sizes with strong adaptability.

3.High production efficiency:

The hot expansion tube process can achieve continuous production, the process is relatively simple, the production efficiency is high, and it is particularly suitable for mass production.

4.Good product quality:

The tubes produced by the hot expansion process have uniform internal structure, refined grains, improved mechanical properties, and good strength and toughness.

5.Low equipment investment:

Compared with processes such as cold drawing and cold rolling, the equipment required for the hot expansion tube process is relatively simple, the investment cost is low, and maintenance is convenient.

6.Flexible process:

By adjusting the heating temperature, expansion speed and expansion ratio, the final size and performance of the pipe can be flexibly controlled to meet different usage requirements. In general, the heat expansion process has the advantages of high efficiency, flexibility, wide application range and low production cost, and is an important pipe processing method.
