I. Raw Materials
The quality of stainless steel pipes depends on the quality of the raw material, steel strips. The quality of stainless steel raw materials in the current market varies greatly, with both refining furnaces and medium-frequency furnaces available. Different raw materials result in different qualities. Some stainless steel pipe manufacturers, due to cost issues, choose medium-frequency furnace steel strips as raw materials when selecting them. As a result, the stainless steel pipes produced in this way may have some quality problems. Such as dark color, hard stainless steel pipe, uneven wall thickness of stainless steel pipe, difficult to process, prone to rust, etc.
How did Jiangsu Fland Stainless Steel Company solve this problem? Since the establishment of the factory, we have always selected raw materials from refining furnaces to ensure the quality of each stainless steel pipe. The stainless steel pipes produced not only have high brightness, but also are soft and more suitable for processing. Moreover, nitrogen is used for internal protection during the welding process to prevent rusting.

Two, production process
The stainless steel pipes circulating in the market may have problems such as missed welds, off-center welds, and undercut. Some stainless steel pipes also have issues like round pipes not being round, square pipes not being square, and length errors. It has brought a lot of trouble to the processors in processing and manufacturing. Jiangsu Flanders Stainless Steel Processing and Sales Company adopts a hierarchical quality inspection system. Each process is inspected by dedicated personnel, and the quality inspection requirements are strict, such as the quality inspection standards for stainless steel round pipes
