Product Details

Stainless steel tube can be easily classified as stainless steel seamless pipe and stainless steel welded pipe. 

Since the 1930s, with the rapid development of high quality strip steel rolling production and the progress of welding and inspection technology, constantly improve the weld quality, increasing varieties of stainless steel welded pipe specifications, and in the field of more and more especially in heat exchange equipment, decorative, low pressure fluid in the tube instead of stainless steel seamless pipe.

With the rapid development of China's economic construction, the consumption of stainless steel is increasing, the demand of stainless steel tubes is expanding, and the market prospect is promising. Stainless steel seamless tube’s market demand performance in terms of basic industries, such as petroleum, chemical, power generation, it is a third of the total consumption demand of stainless steel tube, and such as automobile, shipbuilding, construction and environmental protection, etc. Stainless steel welded pipe is mainly used for heat exchanger tube, fluid tube, pressure pipe, mechanical structure tube, urban landscape, etc., and annual consumption is about 700,000 tons. The industrial use of stainless steel weled pipe is of high demand, and the production process is mature. In our country, we use the stainless steel weled pipe of industrial use for about 150 thousand tons.
