310S stainless steel is a kind of Austenitic chromium-nickel stainless steel, which has a very good Oxidation resistance, corrosion resistance performance. With a high composition of Ni and Cr, 310S stainless steel material can be used in extreme environment like acid, high temperature, high oxidative. Therefore it is widely used in boilers, steam turbines, industrial furnace and aviation, petrochemical and other industries.

Advantages:

1. Raw material choices.

All of raw stainless steel coils are from YUSCO, Baosteel, TISCO.
From slitting to production, we care more about the tolerance and raw material mechanical parameters to guarantee the tube quality control.

2. Various mold choices

With years of development, shanghai Yieh United Corporation is able to produce various OD tubes with different thickness.

For OD<50mm, Shanghai Yieh United Corporation has induced automatic welding machine. The daily production is 150 tons.

For OD>50mm，Shanghai Yieh United Corporation apply advantageous manual welding process.

3. Surface Polishing.

Shanghai Yieh United Corporation can offer different tube and pipe surface from No.1 to #400 surface based on customers' requirement.

 

4. Pipe Surface Pickling.

5. Quality Control(Water pressure check)

For every welded tube diameter <50mm, Shanghai Yieh United Corporation strictly test every welded tube in order to guarantee the quality for our customers.

Curently, Shanghai Yieh United Corporation has three different production lines including welding, cold drawing, and cold rolling.

1. Welding.

 

2. Cold drawin and Cold rolling for seamless stainless steel tube and pipe.

Based on customers requirement, Shanghai Yieh United Corporation has two production lines.

For OD<100 mm, cold rolling is applied to guarantee the surface and tolerance requirement.

For OD> 100mm, cold rolling is applied to reach the tube diameter.

The overall production Process:
